The VM-Q401A color quad processor is used in CCTV camera systems to take analog video input from up to 4 CCTV cameras and split / switch the video output based on the users preference. Typically, the VM-Q401A is used as a quad screen splitter (4 cameras on one screen), however, this CCTV quad allows the user to control the video display output using the following modes: quad split, full screen, PIP (picture in picture), dual screen (2 camera split), auto sequence.
Please see the below sample CCTV quad multiplexor images for examples of these video modes. You can also watch a video demo of the VM-Q401A CCTV quad and see how-to install the quad here. The VM-Q401A can be used on its own as a stand alone video processor that controls video output to a monitor. The Q401A can also be used in conjunction with a video surveillance VCR recorder. The VM-Q401A quad video processor supports analog video resolution at 720x480 at 60hz for NTSC video format, and 720 x 576 at 50Hz for PAL analog video format systems.
