Abstract A CMOS camera image sensor that may be combined with additional CMOS camera image sensors to form a multiple-camera security monitoring system. Each CMOS image sensor includes phase-locked loop circuitry. The phase-locked loop circuitry receives a reference input signal and in response thereto synchronizes the video output of the CMOS image sensor to the reference input signal. In one configuration, one of the CMOS image sensors provides the reference signal, while in another configuration, the reference input signal may come from an external circuit. Each CMOS image sensor also includes state selection circuitry. The state selection circuitry allows the video output from the CMOS image sensor to be displayed on 1/4, 1/2, or all of a display. Thus, the video signals from multiple CMOS image sensors may be displayed on a video monitor simultaneously.
