Although this example uses a network camera, the same principles apply to any type of IP-addressed electronic security device, such as video servers, access control interfaces, or alarm transmitters. Although there may be unused RJ-45 sockets available in the work area, and the temptation great to connect the camera to them, this should be avoided. It is too easy for a person to unplug the camera’s network connection from the wall, and it’s also probable that at some point the client will need that particular network socket for the enterprise network or a telephone connection. The security contractor should install new UTP cable from the camera location to the horizontal cross-connection room, placing male RJ-45 connectors on each end to plug into the camera and the patch panel within the horizontal cross-connect.
Many of today’s network cameras are powered by low-voltage AC, supplied by a plug-in transformer. Security installation technicians need to make sure that the AC outlet selected is not on a switched circuit, which can kill power to the camera. They also should ensure that the location for the plug-in transformer is not easily accessible, which would allow someone to inadvertently or deliberately unplug the transformer.
