Question:  How does a CCTV surveillance camera get tested before installation? 

Answer:  Republic ITS is an electrical contractor that installs closed circuit television (CCTV) cameras, either through maintenance or installation contracts.  We perform a simple bench test before installing cameras.  The photos below show a recent test of Cohu cameras, using a simple wood support, a Cohu control panel and a test kit, and a laptop with Cohu software.  The test procedures include verification of basic camera functions through image transmission, proper pan tilt and zoom operation, and camera pressure readout.  The test takes about an hour to set up and about 5 minutes per camera to run.
