Multiple Camera Monitor Display for Boat Monitor

Here is a solution to display multiple camera feeds on a single marine boat monitor. I recommended this solution when a marine technician who contacted me with the following questions.

My company services boats, yachts, and ships. We are currently remodeling a yacht for a client and are looking for a solution to display more than one camera on an existing screen that is part of the yacht’s bridge system. The 19″ monitor that we are currently using supports 1280 x 1024 resolution and has a composite RCA input and a DVI video input. Right now we have a single CCTV camera that is mounted in the engine room connected to the monitor’s RCA input. The camera uses coax cable with BNC connector on the camera end and an RCA connector on the monitor end.

We would like to add 3 additional cameras to this system and have them all displayed at the same time on the 19″ monitor. I have read that a multiplexer is what I need to combine the video signals.

Do you have a video multiplexer that would be compatible with this monitor and our existing cameras? Do you have cameras that you recommend that we can use to expand the system?

This is the advice that I gave to this customer.

Please take a look at this multiplexer video solution for boats. Your existing camera can connect directly into one of the BNC video input ports on the multiplexer. You can use this BNC to RCA converter so that you can use your existing camera cable.

The video multiplexer used in this system will work with your existing analog CCTV camera (CVBS video) and also with the latest 1080p HD-over-Coax cameras. All BNC inputs support the following video formats: analog CCTV / CVBS, AHD, HD-TVI, HD-CVI.

This is how the whole system works.

1. RG59 Siamese coax cable is used to wire the cameras to the video multiplexer. The coaxial portion of the Siamese cable (blue line above) connects the BNC video output of the camera to the BNC video input of the multiplexer. These BNC connectors are crimped on the RG59 cable.
2. The power cable built into the Siamese cable is connected to a 12V DC power source. You can use individual DC transformers that are included with the camera or a multiple camera DC power supply box like this. You can also tap into an existing 12V DC power source if you already have one on your boat.
3. The VM-HD4 multiplexer has 3 video outputs: HDMI, VGA, and BNC, which make it compatible with just about every marine monitor. You can use a HDMI to DVI converter cable if you want to use the HDMI output or you can convert the BNC video output to RCA.
4. The dome cameras that are use in the above application are these IP68 rated armor dome cameras. They are very popular for use in marine and other harsh environments.
