This photo shows the traditional method of installing CCTV systems (without SmartBay). The combo cable is stripped back one meter so that the Coax can terminate at the DVR. The two power cores are twisted together using a drill and wired up to a shelf containing four switch mode power supplies, the PSU’s are wired into 4 terminal strips with copper wire links distributing the +12VDC power to each camera. Note that in this particular installation a cable fault would take out 4 cameras and cause a switch mode PSU to shut off its output. Cable termination time was 2 hours (for the power and BNC’s for a single technician), changing an input on the DVR would mean unlocking the cabinet removing the DVR and plugging the cables into the DVR on the desired port, this caused uneven length on the coaxial cables. The cables used a Numbered Tape to designate which camera they went to. There is no redundant PSU facility nor can one be installed without significant rewiring. Installation and configuration of the DVR required the help of the cable installer to identify cables.
