Product Code: VM-Q401A



The VM-Q401A color quad processor is used in CCTV camera systems to take analog video input from up to 4 analog CCTV cameras (CVBS) 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. The VM-Q401A includes the power supply and a infrared wireless remote control which allows users to access all settings and controls.

The VM-Q401A supports analog CCTV cameras only (D1 and 960H resolution). NEW! Please check out this product if you are looking for a quad video multiplexer that also works with 1080p AHD and TVI cameras.

5 of 5 Awesome Quad! November 16, 2013
Reviewer: CCTVman72 from USA  
This is the best quad that we have used and is the only one that we have been able to find that has a dual screen mode. The wireless remote that is included is really handy. This unit is a great value. Highly recommended!
