• Cables. Systems should be connected with signal cables from the cameras to the TV, VCR, computer or DVR for recording purposes. DVRs and cameras should have power cables. It is a must to determine where the camera will be mounted so that you will know ahead of time how much cable you will need. Make sure that the system you buy includes cables to get the system up and running.
When shopping for a c-mount security camera, it is important to remember that they do not come with a lens, which makes them both initially more expensive and more adaptable. Having a more expensive initial price tag does not tell the whole story, however, as most c-mount cameras become far less expensive in the long run. The reason for this is that often a c-mount camera can be repositioned in a security setup that has changed simply by buying a new lens rather than having to buy a new camera.
• DVR. This is a hard drive that allows you to record and playback the video feed from the security system. When the memory becomes full, the new video signal will then overwrite the oldest one. There are some systems that have memories large enough to record 150 days worth of footage.
