This module stabilizes and monitors the power from the vehicle’s reversing light to reliably power the rear-view camera. It helps prevent video errors, wobble, or a blank reverse screen caused by unstable or pulsed power on the reversing-light circuit. Key benefits - Quick detection of reverse-light voltage issues: Designed to identify when the camera could experience abnormal video output due to unstable supply. - Detects interference on the power line: Some vehicles generate pulsed or non-pure DC signals on the reverse-light circuit; this unit helps determine if such signals are present and affect camera performance. - Easy plug-and-play installation: Connect the input to the reversing light positive and negative, and connect the output to the camera’s power terminals. Red wire goes to camera positive; black wire to camera negative. The input includes a reverse-polarity lead for protection. - Stable, reliable performance: Addresses and fixes screen shake or black-screen symptoms during rear-view camera operation with professional, high-performance design. Function and compatibility - Function: Power the rear-view camera from the reversing-light circuit while monitoring and stabilizing the supply to prevent video issues. - Compatibility: Particularly beneficial for vehicles where reverse-light power is not a pure DC source and for vehicles that previously exhibited interference or unstable camera output (including some German and American models). What you get and how it works - Wiring: Simple two-wire input connected to the reversing light (positive and negative). Output wires connect to the camera (red to positive, black to negative). The input features a reverse-polarity line to help ensure correct wiring and protection. - Build: Professional manufacturing with a focus on durable, stable operation for automotive installations. - Size and placement: Compact module designed for easy integration into standard rear-camera wiring harnesses. Use scenarios - Scenario 1: Upgrading a rear-view camera on a vehicle that shows intermittent video or screen shake due to fluctuating reverse-light power. - Scenario 2: Auto-shop retrofits for cars from markets where reverse-light power can be pulsed or noisy, ensuring a stable camera display after installation. - Scenario 3: Fleet vehicles or work trucks where reliable rear-view camera performance is essential, even in models with non-ideal reverse-light power characteristics. Notes - Installation is straightforward: connect input to the reverse light circuit and output to the camera's power input. Red to camera positive, black to camera negative. The device includes a line for reverse polarity to help prevent damage from incorrect wiring.
