The Video quad
splitter is a very important component of close circuit television systems.
Quad splitters were developed to eliminate the not so cost effective way of one
camera per monitor and time lapse recorder design. A Quad enables the user to
view up to four cameras on the same screen simultaneously. It displays all
cameras on the screen two on the top quadrants and two on the bottom quadrants.
This gives the user a tremendous advantage over security camera systems using
video sequential or manual switchers. Using a quad, the system operator will
not miss any activity he or she would have if they were using a sequential or
manual switcher. However there is a slight drawback to the quad splitter. Its
images can sometimes be too small to distinguish any specific details on an
image, especially when using small CCTV monitors.
While viewing a live feed this drawback can be overcome since the quad allows full screen viewing of any camera with a simple push of a button. However the same cannot be said once a picture has been recorded. When a quad output is recorded, it is recorded the same exact way as it is seen on the screen. Therefore if a quad view is being displayed while recording that’s the only way it can be retrieved on playback. And if an operator has switched to a full screen camera view while recording that will be the only camera that could be viewed on playback. As you can see this could pose a problem in many applications and is also the main reason why many people upgrade theirs systems from quads to video multiplexers.
