The basic ViewPro™ camera to Observation monitor connection is accomplished using the supplied 60' RJ-11E camera cable connected to one of the RJ11 camera inputs on the back of the Observation monitor. Industry standard CCTV cameras with BNC (twist-on bayonet) connectors may also be used with the ViewPro™ system. Connection from the BNC camera to the observation monitor is made to one of the BNC camera inputs on the back of the observation monitor.
