  • It is a misconception that using a webcam is just to record yourself doing something beneficial or entertaining. A webcam can also be used a security surveillance system. For instance, if you want to see what your children or employees are doing while you are away, just hook up a webcam and watch it from a remote location.

The military is even using the technology to allow troops to communicate with their families after they have been deployed to other countries. Many college kids like to use webcams to communicate with their friends who are away at schools in different states. It is a faster communication than writing letters and more enjoyable than emails.

  • The first thing that needs to be done is the buying and setting up of the webcam. Some webcams are very simple to connect to your computer; all you have to do is connect it to the USB port on the computer. Some webcams are much more complex. Follow the directions that come with the packaging.

  • There is software that comes with the webcam that allows you to captures the images and videos. Depending on what you need the webcam for, the proper settings need to be in place. The frame rate should depict if you want streaming video or still images. For streaming video, the frame rate needs to be set very high.

  • Once the camera and software is installed, you now need a way to broadcast the images and videos. Some utilize their own web server or use one of the free resources available. After you have decided on what server to use, set up an account and copy down the server address the FTP information to include it in the webcam settings. Your computer is now able to capture video and photos then upload it to a web server. Your software will continue to capture and upload the images while you have it in capture or record mode.

  • For recording streaming video, you will need a constant connection to the internet. This way you will be sure to receive up-to-date images captured from your webcam. A reliable and fast connection is also needed on both computers when communicating between two webcams.
