How to use a webcam as a cctv

One of the major differences between a CCT-type video camera and a webcam is that the webcam's USB cable can not travel as great a distance as that of a coaxial cable-attached CCT. To use the webcam as if it was a CCT camera, use a USB cable adaptor so that coaxial cable can be used. The adaptor can be acquired from an electronics store or select computer shops. You do not need to modify the webcam.

  1. 1

    Plug the power cord from the USB adaptor into a wall outlet for power. Plug the USB cable attached to the webcam into the USB port on a USB sending adaptor. Examples of a sending adaptor include the Sendtek Coaxial USB adaptor, the Forvus Coax adaptor or the CNC USB extender adaptor. Place the webcam on a table or shelf so that the lens faces the area of the home that is to be monitored.

  2. 2

    Screw in one end of a coaxial cable into the coaxial output on the adaptor. Run the coaxial cable along the baseboard of the wall until you come to the computer.

  3. 3

    Screw the end of the coaxial cable into the coaxial input on the USB receiver adaptor. Plug the adaptor's power cord into a wall outlet for power. Plug the USB cable attached to the adaptor into a free USB port on the computer; if there is no USB cable attached to the adaptor, insert one end of a USB cable into the USB output port on the adaptor and the other end into a USB port on the computer.

  4. 4

    Click the red "X" in the upper right corner of the "Adding New Hardware" window when it pops up on the computer.

  5. 5

    Download a video surveillance program to the desktop. Popular programs for this use include the free Vitamin D program, the trial version of webcam Video Capture or the trial version of Debut Video Capture Software. Double-click the file once it has fully downloaded to start the installation. Follow the menu prompts to install the program onto the computer's hard drive. Quit the installation once you are done.

  6. 6

    Launch the video surveillance program by selecting it from "All Applications" under the "Start" menu. Follow the configuration wizard that pops up to select the video source being sent by the webcam. If a wizard doesn't launch, manually select the webcam from the "Video" or "Source" menu on the program's main screen. You can now monitor the video being sent by the webcam on the program's video window.
