What are simplex and duplex and triplex capabilities?
A9: These are simply terms which define the nature of the processor. Many 4 camera systems are simplex and usually feature two video output ports on the back- one to go to the monitor and one to go to a video recorder (DVR or VCR). The output signal from the monitor port shows all 4 cameras unless a single camera is selected as “full frame” on the screen. The output signal from the “VCR” or recorder port will continously display all 4 cameras regardless of what manual functions may be in operation by the user. Duplexing systems essentially allow user to “loop through” to monitor one camera while still recording the others. Duplexing systems actually record individual camera frames rather than all at once- allowing user to select a single camera during playback of recording- regardless of what manual selections were made onscreen by operator during recording. Triplex systems are found as digital devices which allow simultaneous monitoring, recording and playback of different events! It
