A request came in from one of our customers asking for help to find a solution to their Android Headunit with multiple camera support for the motorhome idea.
We were happy to help.
Multiple cameras
The customer’s idea was to install multiple cameras. This was to blind spot assist when turning and a better view than just a reversing camera when backing up. The problem is that although some of the Android headunits do have video in and reversing camera inputs, they do not support enough cameras to get the enhanced view required.
Intelligent camera
A solution considered for the multiple cameras was the universal PAC Intelligent camera switcher. This device has 4 camera inputs and one camera output that will interface directly into the Android headunit ‘video in’ connector. The intelligent switcher is also connected to the turn signal indicator circuit and the reversing light circuit and these allow the switcher to allocate which camera input is switched to the Android video in.
Connections
There is a wide range of signal inputs for turn signals, speed signals, and backup signals to allow the switcher to select the correct camera to display on the android headunit screen. There are also connections to the 4 cameras. This does create a fair amount of work to run the cables in and get them connected to the correct places.
