More Upgraded Features: With loop recording, simply insert an SD card to record moments or evidence of your vehicle. The image can be set to either front view or rear view as needed. If you add more cameras to the system, it can be set to split-screen mode, allowing you to monitor your surroundings simultaneously.For GMC/Chevy/Ford Owners: Newer GM vehicles utilize PWM power, which may interfere with video transmission—resulting in flickering / signal loss / screen freeze. To ensure stable performance, we recommend adding a Furrion 7-way adapter (not included) or a 12V PWM filter (not included). These accessories help clean the power supply, restoring reliable camera operation. Tip: To confirm if your vehicle uses PWM power, you can use portable 12V Power Supply or Household Power Supply Testing.Wireless Transmission: The BW7M system wirelessly transmits video between the camera and monitor (no video cables required). However, both units require wired power connections to ensure stable power supply and consistent performance, which is crucial for the camera to function properly. (Note: "Wireless" refers only to video transmission)The BW7M camera system can be used as a back-up camera (wiring to the reverse lights) or and observation system (wiring to the running lights). Make sure you have whatever lights the camera(s) are wired too on when testing the cameras. If you have it connected to the running lights, then the running lights need to be on for the cameras to receive power. This is a common thing that gets overlooked when testing the camera.Please note that this system is not compatible with the furrion cameras.
