Our CCTV System features four 3.5 - 8mm varifocal color cameras, and 14" color monitor with built-in sequential switcher, which minimizes the number of components and connections required for set-up. The ProVideo Advantage allows for the addition of any CCTV camera to these systems using our rear BNC inputs! Each system camera has a built-in miniature microphone and 2-way communications speaker. A sixty ft. cable and camera mount also included for each camera. All monitors have an alarm input and output via rear terminal strip. Additional B/W (PVS-CAMB) and Color (PVS-CAMC) cameras are available for the expansion of the CCTV system. Available system accessories include a PIR motion sensor (PVS-PIR), external speaker (PVS-SPK), 100 (PVS-C100) and 250 (PVS-C250) ft extension cables, and an extension cable coupler (PVS-DIN).
