Basics of the Internet

By Pocholo Peralta

The Internet in its earlier decades was simple and easy to use. But as years go by, it becomes more complex and very fast. After using the Net for more than four years, I got inspired to review its basics because I seem to have forgotten it! Let’s get back to Internet basics and basic components.

The most prominent component of the Internet model is the Internet Protocol (IP) which provides addressing systems (IP addresses) for computers on the Internet. It enables internetworking and essentially establishes the Internet itself. But one of the cause of Internet connection problems is the exhaustion of IPv4 (IP version 4) because of the explosive growth of the Internet. Now we wouldn’t be in the basics anymore if we continue so…

Connecting to the Internet

Broadband – Most users prefer this connection because it’s the fastest and most stable. But you can only use this on a fixed location.

WiFi or Wireless – As opposed to broadband, you can use this connection where ever you are, ergo wireless.

Programs and Applications

Before you can do something with your computer, you must have programs and applications. When you buy a new computer, there are already installed programs that would let you add more.

Browsers

Browsers are the doors to the Net. Our connection to the Internet is useless without them. In order for us to browse or ’surf’ the Internet and connect to other websites, we need to use browsers. Examples of Browsers:

Google Chrome

Ubuntu

Firefox

Opera

Safari

Explorer

Networking

The main reason for connecting to the Net is networking which is sharing of resources and information among computers and devices connected to the network. By networking, users can communicate efficiently and easily via e-mail, instant messaging, chat rooms, telephony, video telephone calls, and videoconferencing.

Social Networking is mainly done for leisure. By using programs and applications, people can join a social network and exchange messages and pictures. The most popular social network sites are Facebook and Twitter. Serious working people see social networks as time wasters.

Internet Safety and Security

Many new computer users don’t realize that maintaining their gadgets isn’t a simple task and fail to maintain the safety and security of their computers, either unintentionally or by recklessness, until one day, their computer ‘crashes’ and find out that their gadget wouldn’t work anymore.

Tasks for maintenance and safety:

Updating Operating System

Updating Browsers

Updating Antivirus, Antimalware, Antispyware

Using link scanners that check if the site we plan to visit is safe

Deleting suspicious ‘flash cookies’

Doing all these tasks regularly

(And I’m not sure yet if these tasks are complete!)

We can update any of these automatically but sometimes for some reason, it stops working. So another task is checking for updates.

Things that could happen if we ignore safety:

Malfunction of your computer

Malware, spyware, or virus infection which could stop or ruin our computers

Identity theft which could lead to stolen bank accounts -This is the most dangerous and most popular among computer criminals

Hijacking of your personal weblogs, email account, or sites

I hope I have convinced us all that Internet security is a must. Some techies believe that we have to be paranoid about our internet safety to be really safe.

5 Tips to Help You Have Great Skype Calls

By Meghan Burton

Are you having some trouble with popular VoIP program Skype but you have no idea how to fix it? If you’re not entirely tech savvy, you may be struggling and tempted to give up on it before you’ve even begun. Don’t worry! Here are solutions to five common problems. These are all easy solutions that anyone can understand and implement.

1. Bad Call Quality

The most common cause of poor call quality on Skype is when two users are running different versions of the program. The codecs will not be compatible which leads to echoing, lost voice packets, and general difficulty. It’s easy to fix this; each of you needs to update your own program. Just navigate to the main website and download the newest version. Alternatively, you could click on “Help” and “Check for Updates” in the Skype menu. If that option greys out, there are no updates. If there are, the program will guide you through installation of them.

After installation, check to see if the situation has improved. Skype is regularly improving on its codecs and you should always update for the latest one.

2. Call Quality Fluctuates Even After Updates

Check your internet quality. Are you doing something else online, like downloading or uploading a large file? Do you have a very low speed connection to the internet? These issues can combine to lower your call quality. Unfortunately if your internet speed fluctuates, there’s nothing you can do, but you can try not to download or upload files while you are chatting on Skype. This includes browsing large websites that may have excessive use of flash.

3. Webcam Picture Is Blurry

If your webcam looks dark, check that it’s securely connected to your computer and installed properly. Try opening it in its native program (after closing Skype) and troubleshooting from there first because that program may recognize more issues than Skype will. Turn more lights on so that the lighting is more central. Very few webcams will provide good quality video in a video call, but you can improve it with even, bright lighting.

4. Webcam Isn’t Working at All

First, check that Skype is recognizing your video. Go to Tools, Options, and then choose Video Settings under “General”. You should see an image of yourself. If you don’t, first check that no other program is using your video. You won’t be able to do both. If it still doesn’t work, again ensure that your version of Skype is fully updated. Update your webcam drivers by going to your manufacturer’s website and downloading new ones for your model. Sometimes older webcams struggle with Skype.

5. How Do I Block Someone?

Just like any instant messaging type service, Skype unfortunately has its fair share of spammers. If you receive inappropriate message or invitations to video calls, you naturally want to take the next step and block those users from accessing you again. Blocking is easy. Just right-click on the person’s name from the instant message or the call and choose “block this person” from the menu.

If you’re having a lot of problems or you simply don’t want others to view when you’re on Skype, you can also go invisible. This will mean that only you can initiate calls and instant messaging conversations because everyone else will see you as logged out. In order to do this, click on Skype at the top, then hover over online status. Invisible should be one of the options.

The Skype website is a fantastic place to investigate if you have more tech knowledge or are having a different problem. I hope these tips helped!

Your Mozilla Firefox is Slow? How to Effectively Boost the Browsing Speed

By Jacob A. Turner

Your Mozilla Firefox is slow because of a number of reasons we would trash out in this discuss. Mozilla is one of the best browsers on the entire internet world at the moment. It’s uniqueness sterns from the fact that it supports several other operating systems such as Linux, Mac, Windows and many others. You may need to boost the speed of your Mozilla browser sometimes. Follow the Firefox tweaks below to enhance the speed of the browser.

Start by typing: ‘about:config ‘ on the address bar of the Mozilla Firefox. You would be taken to a page where you are asked if you want to proceed or not. Just click ‘ENTER’ so that you would be taken to a list of configurations and many more. This configuration is almost universal in nature and is the exact configuration used by most irrespective of the computer’s speed or the connection type. The configurations are as follows:

On the filter tab; enter ‘network.http.pipelining’, then double click on the network.http.pipelining field, and then set the value you see there to ‘TRUE’. You should set the next value to ‘8′ by double clicking the next field that says: network.http.pipelining.maxrequests.

Then get back to the filter tab and type ‘network.http.proxy.pipeliningand hit ‘ENTER’. Set it at ‘True’ by double clicking ‘network.http.proxy.pipelining’ field.

Now, right-click on any corner or anywhere on the about:config result and simply choose new and then integer. Follow it up by typing ‘content.notify.backoffcount’, then click ‘OK’ and set the value to ‘5′.

Then type ‘network.dns.disableIPv6′ on the filter tab you see there. Don’t forget to set this to the value ‘TRUE’ too.

Lastly, set the ‘ui.submenuDelay’ to the value ‘0′. To find this, simply right-click on anywhere on the about:config result and follow it up by choosing new integer.

The Mozilla is slow but not after completely this detailed reconfiguration. You would definitely experience faster and better browser.

There are lots of configurations on any browser because of the nature of their primary task, that is helping to gather data from all over the internet but the ones we have discussed above are those that simply would help to hasten the speed of your browser. You don’t need to worry about what may have happened to you computer is the speed suddenly disappears. It may be as a result of certain configurations that needs readjustments or some certain actions you have earlier taken that require redress.

If your Mozilla Firefox is slow after reconfiguring certain configs, it is the time to look in the direction of the registry. It is true that the registry performs a lot of useful tasks. It sometimes gathers more information than it can process and gets ‘confused’ in the process. This usually results in wrong saving of certain data. This kind of confusion usually results to slow speed of the entire computer because it would be difficult for it to interpreter the actions you are requesting. By trying to properly ‘read’ what you are asking it to do, the result takes time and this is what causes most of the slowed system speed.

How to Ensure Data Security by Using an Effective Firewall

By V K Rajagopalan

Data security is extremely important for every person that uses a computer system. One of the best ways that you can ensure data security is by using a firewall. A firewall is a program that is built in to most computer systems. It can also be a hardware device that helps to block intrusions from worms, hackers, and even viruses.

The intrusions that the firewall blocks are those that try to reach the system through the internet. While you can ensure data security by way of a firewall, it is essential to understand that it needs to be supplemented with a decent program that focuses on eliminating viruses and spyware. This will ensure maximum protection.

If you are on a network, whether it is in the home or at a business, it is absolutely essential that you ensure that you activate a firewall on each and every single system in that network. Many feel if they have a router, which is a firewall that is hardware based, that is enough. However, it is not. Every computer should have an active firewall on the system.

You may find that choosing a firewall for your system is a challenge. There are three basic types of firewalls that can be selected. First, you have the standard firewall that is a software program. Next, you have the firewall that is an actual piece of hardware. Then, you have a firewall that is automatically built in to the wireless routers that you find on many types of networks.

In order to determine which type of firewall is most appropriate for your particular situation, there are a few things that you must consider. These considerations are as follows:

1. How many computers will this particular firewall be responsible for handling?

2. What types of operating systems do these computers implement? An operating system is represented by Microsoft Windows, Linux, and Macintosh.

If you have a Microsoft Windows operating system that has XP with the Service Pack 2 or the Vista version, you may benefit from using the firewall that is built in to Windows. This firewall is built in to the system and it automatically turned on to ensure data security.

Many individuals who have Windows XP have elected to not download Service Pack 2. If you are one of these individuals, you may be wondering if it is possible to benefit from a firewall that is built into Windows. The answer is “yes”. You can enjoy protection through the Internet Connection Firewall, but it is important that you turn this function on in order to benefit from the protection that it offers.

There are many different types of firewalls that you can purchase as standalone software for your computer system if you elect to. These types of firewalls are extremely beneficial for individuals who have the operating system of Windows 98, ME, 200, and even Linux, and Macintosh. The only real downfall to these types of programs is that they can prove to be costly and it may prove to be challenging when it comes to the initial installation and configuration.

The latest version of Windows is Windows 7 which was released sometime in October 2009. This version has proved to be the best among all earlier Windows operating systems in terms of functionality, built-in security features and ease of use. I would strongly suggest that you upgrade your computer’s operating systems to Windows 7 at your earliest.

If you have a network in your home, or at your business, it may be best to have the firewall of a hardware router. These pieces of hardware can connect many different computers at once. This security is supplemental to any firewall that is already installed on the computer systems. It does require a little wiring when it comes to setup. This is a minor complication compared to the dangers that hackers, worms, and viruses can pose to your system.

If you have a wireless network in your home, it is important to ensure that you have a wireless router. Not only does this router assist in establishing an internet connection, it is also beneficial in acting as a firewall. The downfall to these types of firewalls is that it broadcasts a signal via radio waves that can be accessed by someone outside of the network if they know how to do so.

If you use a wireless router, it is important that it is equipped with a proper password. It may take some money to purchase the additional equipment, but it is well worth the safety and security that is offered to your network. This is essential to ensuring the protection of your data. If you want to ensure the data security on your computers, a good firewall, or a multiple firewall is an absolute must.

And, to help you learn to use computers and the internet safely and effectively, I invite you to take a look at my computer training website. You would get lot of useful tips when you visit http://www.ctfy.net. From Rajagopalan, A computer professional helping people in the usage of computers with safety and security.

Android Application Developer – A Whole New World of Possibilities

By Kim Dsoza

Google’s Android operating system has taken the world of mobile application development by storm, for quite some time now. Granted, there are still less number of apps available for the platform compared to the other platforms like iPhone, Blackberry and Symbian but this is for sure that Google’s Android has already started spreading its tendrils to other handsets. On its recent earnings call, T-Mobile announced that it has sold its one millionth G1 phone based on the Android open-source operating system, meaning it took Google just six months to do this. This by all means is an impressive feat considering the incredible anticipation and fervor for the iPhone.

Android apps cost a good amount each, and hence can be used to rake in a steady stream of income over time. Here are the advantages that I foresee for building an Android application vis a vis other platforms:

1. Android OS Roils SmartPhone Market: Android Mobile Operating system was introduced a year back and could hardly give a competition to Apple iPhone but with the recent slew of new Android based devices the growth has been phenomenal with a phenomenal 15 point jump in just 3 months.

2. Huge developer community support: The Android platform is open to all, and as such there is a dedicated community of developers actively working on this platform. If there are any troubles that the developers run into during the development phase, there will always be help at hand. Besides, if there are any bugs, community members will also offer help during testing phase. This will make sure that your apps are stable and bug free when those are released.

3. Ease of Development and Porting: By default, Android is configured to auto-scale everything in most cases, however if layouts are specified with exact pixel values rather than the other suggested options the developers can easily make the necessary changes with the help of published content. The support for porting legacy applications to add support for larger or smaller screens is rather much simpler in case of Android. Sometimes it might be as simple as adding the following into their AndroidManifest.xml

4. Stable platform: Owing to its Linux core, the Android operating system from Google exhibits rock solid stability and resists crashes. As such, the apps developed on this platform exhibit the same characteristic, resulting in rock solid stability, resistance to anomalies in the system.

5. Many sales options: The Android apps can be sold in a variety of ways. There is the Android App Market, which the majority of users access in order to purchase and download Android apps. Secondly, there are third party stores that just about anyone can use to sell their apps. Even you can set up your own store to sell the apps, which is a huge plus, considering many other popular platforms force you to sell apps from their stores only.

6. Excellent ROI: The Android apps cost quite a good amount to download; hence you can be assured of getting excellent returns over your investment. All you have to do is find a good Android application developer for getting your apps built, and upload it in a store that is offering good commissions over sales.

As Android’s growth continues to explode since the release of the Droid, one developer, in fact, wrote that his app, which was showing modest, double-digit daily sales late last year, now reports that his app is making $13,000 a month.

But in order to net a steady stream of income it is important to partner with a well reputed organization with an established record of delivering robust mobile applications and someone who can contribute not just from technology perspective but also add value by engaging in providing suggestions for future enhancements of the product.

Motorola QUENCH – New Tricks From an Old Dog

By Simon Drew

Motorola, the world’s third largest mobile phone maker after Nokia and Samsung has unveiled its latest Android smartphones at the recently concluded 2010 Mobile World Congress held in Barcelona.

The Motorola QUENCH with MOTOBLUR is its 8th Android sporting the older 1.5 Cupcake version just when many new unveiled Androids have started using the new 2.1 Éclair. But this just confirms our suspicion that because of its open source nature, Android versions, unless severely handicapped, can easily be tweaked to rival even the latest versions coming from Google.

It also further buttresses the observation that no upgrade paths are necessary. Versions remain as OS variants with UIs like Sense form HTC and UX from Sony Ericsson making an upgrade irrelevant. The suspicion is finally confirmed when Acer came out with the latest Liquid e showing nothing else but the new 2.1 Éclair OS when they could have just provided an OS upgrade to the older Liquid. Apparently, no upgrade path exists from 1.6 to 2.1.

New Features

Despite an old OS, the QUENCH can carry itself proud among the new smartphones running the new 2.1 Éclair, thanks to the Motorola innovations built into the 1.5 Cupcake. It starts with MOTOBLUR which Motorola calls as its content delivery system that promises a unique Android experience.

It syncs your phonebook contacts, media content and communications trail in MySpace, Facebook, Twitter, Gmail and email accounts automatically on the home screen. Then there’s SWYPE, an entirely new method for text input form the same people who invented T9 predictive text. You only need a finger to swipe or trace the letters across a QWERTY keyboard on the touchscreen and the word gets spelled.

Its entertainment features also gets an innovative boost in media players that allow you to play while getting connected online to download new media content like Tune Wiki, SoundHound, GoTV and YouTube.

There’s even FM stereo streaming. The Motorola QUENCH enhances its telephony experience with noise cancellation technology and dual microphones for crystal clear voice calls. You can also benefit from its voice activated search facility that can launch Google Web search.

Apart form these, it’s your 3G phone with WiFi, HSDAP/HSUPA. You get a 3.1-inch QVGA capacitive touchscreen with 64k colors, accelerometer and proximity sensors. There’s a 5 megapixel autofocus camera with LED flash, geo tagging and CIF video recording at 25fps.

Other features include stereo FM with RDS, Bluetooth A2DP, 3.5m headphone jack and speakerphones. There’s 512 MB ROM and 256 MB RAM with 32 GB of microSD expandability.

Conclusion

To a large extent, the various Android versions whether old or new remind us of the many Linux flavours for the PC which created a fragmented market that essentially brought the Linux to fail in the home PC markets.

The QUENCH clearly shows you don’t need a new OS to compete and even edge out the competition using the new Éclair. Thanks to the Open Source nature of Android. But like Linux, it is creating a fragment markets this early and could end the same way.

For the sake of Android markets, we hope Google can get its act right and get a grip of its open source OS. As it is, with all the many OS variants and UI ported by different makers, a single upgrade to the latest 2.1 Éclair from Google, if and when that happens, would simply wipe out all the cool UIs ported into various smartphones. So you can kiss your HTC Sense or Sony Ericsson UX goodbye in one upgrade.

Website Content Management Software

By David T Webb

What is Drupal?

Drupal is an open-source content management system (CMS). Basically its an environment that allows you to develop powerful websites quickly and with relative ease.

Why use Drupal?

Firstly, it’s free. It manages your website content. Easily store and edit all your content and data, display your website pages, easily and instantly edit the appearance of your website using Themes (templates), Color profiles. Drupal lets you easily add features to your website, such as Image galleries, Blogs, Forums, Calendars, Video Streaming, Podcasts, and many other features. Drupal has a large online community, supporting each other and developing drupal add-on modules to provide extra functionality to the system. Get started now with drupal at drupal.org

How Drupal works

All content; such as articles, information, user details, etc, are stored in a database. The database is accessed and managed via a database server. The design and layout of a drupal site is handled by themes. These are template files, styled with graphics and text. Themes allow you to easily change the appearance of your website without modifying any of your content. Drupal uses the PHP programming language. PHP is open-source and therefore free to use.

Drupal requires 3 things to work; A server environment, such as Apache, A PHP Server and a mySQL database server.All of the above can be downloaded in a complete package for you to use while developing websites on your PC. I recommend that Windows users check out Xampp, Linux users can use Lamp. But there are many other all-in-one PHP-mySQL development environments too. Once you have your development environment set up, then you can install drupal and start making websites.

How to install and setup Drupal

Required Software; Development environment: Xampp (Windows), Lamp (Linux), Drupal installation file (compressed archive, e.g..zip or.gz). Download from drupal.org.

Installation steps:

Extract the drupal installation file to your htdocs folder. This is the folder where your website files for your development environment are found. I will assume from here on that you extracted the drupal installation archive to a folder called ‘drupal’. (The default folder is something like ‘drupal-6.13′ with the version included.) Copy the settings.default.php in the ’sites/default’ folder to settings.php. To do this, in your file browser, navigate to drupal, sites, default, make a copy of settings.default.php, rename the copy to settings.php. Create a database for your drupal installation to use, this may vary depending on your development environment and database server. If you are using Xampp, navigate to localhost/phpmyadmin. In the Create new database field, enter the name of your new database, e.g. drupaldb and click create. Finally, navigate to ‘localhost/drupal/install.php’ in your web browser. Follow the instructions to complete the installation of drupal.

How Drupal Themes Work

Drupal displays and styles your content using themes. A theme consists of; theme template files and theme functions. Theme template files display your content through an html and css styled template file. So your site design and content are separate. This means that you can easily change the visual display of your site without affecting the content.

How to change the theme in drupal

In drupal there are two themes that can be applied to your website; the default Theme and administration Theme. The administration theme is applied to the site when the administrator is logged in and is viewing pages under the Administer menu item. In all other cases the default theme is applied to the website. To change the default theme, navigate to Administer, Site Building, Themes. Scroll down to the theme you want, enable it by checking the checkbox. Activate it by selecting the radio button (column labeled as default). Scroll down and click Save configuration. To change the administration theme, navigate to Administer, Site Configuration, Administration theme. Select the name of the theme you want to use as the administration theme. Click Save configuration.

Conclusion

Drupal is a robust, free, community developed open source, multi-functional website creation and management system. It is arguably the best content management system available, under continuous development and improvement. It has detailed documentation on every aspect, from basic to advanced level. To get started with drupal or for more information, visit drupal.org.

The Linux Box in My Pocket

By John Dembowski

My wife and I picked up new ‘phones’ last week. Penny wanted a phone with a slide out keyboard so she would be able to text more easily. I wanted a Droid.

The Droid is a 4 inch machine running a slim Linux Kernel called Android. The whole thing is orchestrated by Google. The machine comes with 16 gigs of flash memory, a 5 megapixel camera, audio player that plays several different formats of music including MP3s, GPS, 3.7 inch touch screen, slide out keyboard, WiFi, wireless broadband, a very sophisticated (free) software installation framework, and, oh yeah, a phone.

Not wanting to scare her off I dumbed it down a tad. I said something like “This one has a keyboard. And you can log into Pandora and stream your channel 24 hours a day.” She was sold.

When were just about done checking out and I’ve had about 1/2 hour to tell her all about ‘this and that’ I mention that it doesn’t come with a manual. You have to learn how to use it by actually using it. Among other things there is a big search box on the main screen. Instinctively you find your way to Google. Google can answer any question.

We each found cool stuff to show each other over the next 8 hours. ‘TV time’ that night became ‘install-try-uninstall time’. We tried out every free Droid app we could get out hands on.

My current app list includes:

* a dictionary

* an app with information on every country

* another with info on each of the United States

* an app with just about every math and physics formula you can imagine

* a copy of the Constitution

* the periodic table with all the basics on each element

* an interface to play audio versions of just about every influential book that has fallen out of copyright

* a crappy DirecTV app to set my DVR to record (better than nothing but this is weak and I expect something really slick and similar to the same searches that can be done directly on the DirecTV box)

* an LED scroller that shows the message you type in (think “Get me a beer, plz” on a lit up sign)

* a light saber with the sound-FX following the Droid’s movement

* the Bible

* the Quran

* several WiFi tools to not only find hot spots but to see which channels have the least traffic

* a ton of relaxation noise machines

* a Darth Vader soundboard

* headlines from NPR and BBC World

* the weather radar for where I happen to be standing (goooo GPS)

* the 10 day and hour by hour forecast from the Weather Channel for where I happen to be standing (GPS is so abused in Android apps)

* a few tools to automate common Android tasks

* a guitar tuner

* flashlight app that turns the flash on and leaves it on until you turn it off

* copied 5 gigs of music to it – turning it into a USB drive for a desktop computer was a tad strange

I’ve spent probably 72 hours during the past week geeking:

* set up all the various options to my preferred settings

* set up the phone to teach me Spanish using 5 different apps

* set up a rather complex Personal Assistant to remind me of just about everything using 4 apps but I’m adding at least 2 more for specific task lists

* on my regular PC I installed the developer’s tool kit, the java programming libraries, an Android OS emulator, wrote and ran a little BS app so I could see what the developers see

* joined a couple Droid-Fanboy forums

* joined a couple Android-Developer forums

* wormed my way out of xWindows and into the underlying file structure

* tricked the phone into doing a full install of the Perl programming language

I can really see a future for the Android OS. I have no idea what is going on for iPhones and BlackBerry. They will not be able to go where the Android will go unless they are willing to let other people use their OS.

Dude, I’ve totally gone Google.

What is So Fascinating About a Wireless Security Camera System?

By Singgih Tri Widodo

From the installation and use, lies in the simplicity and beauty that has a wireless security camera system. With this camera you can send pictures or videos directly to the recipient that the cord is connected to your computer or television. This is a wise way to watch someone who you think is suspect or your goods.

You do not need to buy goods with a very high price for it, and then you get someone else to arrange it. It is not necessary. For that, you should need is some good camera and handy with a computer software and stable, it makes you more calm and comfortable.

Wireless camera – Take a picture

You have the freedom to choose different types of cameras you want to build your own surveillance. You can have 4 to 30 cameras, you want at will. If you want to do off-site supervision, you need to put the camera in certain places. For example pages, swimming pool, main entrance, backyard, etc..

A good outdoor camera should be weather resistant, and must also have night vision. While which indoor surveillance cameras, was far too difficult for a computer or using a simple camera eye to eye. This camera is easily disguised so as not to be seen and caught.

Tips for buying a camera

I suggest before you make a purchase, make sure you check the camera so that the signal coverage to ensure you receive a picture can clearly. It may need a powerful transmitter.

To create a data input, choose the camera to perform voice or movement, and he will activated own end at the appointed hour through the scheme

Recipients / Receiver

Wireless camera basically sending videos and pictures through walls which can achieve distances up to 300 feet 10 miles. By your camera, you will only need can to get a DVR receiver that is used to retrieve the signal is transferred through the camera. The recipient is the most important part of your camera system, without it you can not do anything and can not receive video images you capture which.

This hardware is easy once you plug in the computer or television or wherever you want to install to see it. Usually the camera is equipped with DVR card is which their own and it can directly broadcast to the Internet. But you can buy the device separately at your nearest store shops.

Memory

Data you have on your camera you should keep it safe. You must put the camera in a different place, which surely will make the full leap camera memory. You must buy a separate memory was of about 1 TB hard drive or you need to hire another online server to store your video data. And of course you should regularly monitor your data.

Software

You must have the software to monitor the camera. Maybe you can using a Mac, Windows, Linux, or others. This can help you to monitor, transfer, and store your data. You can see it on the laptop, or phone, or even equivalent to a simple desktop.
