Overview
YIMU's K4302 kit mounts a 150 degree, night-vision camera into a license plate frame and wires it to a 4.3 inch monitor rated IP69K for waterproofing. Power comes from a cigarette lighter, USB port, or a wired connection to the reversing lights for automatic activation.
This is a wired system rather than wireless, which the listing frames as a stability advantage since a hardwired feed avoids the dropouts that can affect Bluetooth or RF backup cameras. It ships with two mounting brackets, one pre-installed for the license plate frame and a smaller one for alternate placement on the front or side of a vehicle. Installation is described as a two-step, roughly 10 minute job connecting camera to monitor and then to power.
- 150 degree wide-angle night vision camera
- IP69K waterproof rating
- 4-pin wired video power connection
- Pre-installed license plate bracket plus a second mounting option
Who it's for
Fits drivers who want a permanent, hardwired backup camera on a car, truck, trailer, RV, van, SUV or camper and are comfortable running a cable from the rear to the dash or a power source. Less suited to someone who wants a wireless setup with no cable run at all.
Pros and cons
- Wired 4-pin connection avoids wireless interference and pairing
- IP69K rating for full waterproofing in rain or wash
- Two brackets included for license plate or alternate mounting
- Adjustable, resizable parking grid lines
- Requires running a physical cable from camera to monitor
- Cigarette lighter or USB power adapter not included in the box
Performance notes
The camera connects to the monitor over a 4-pin video power cable rather than a wireless link, which the listing positions as the reason for a steadier picture with less interference than Bluetooth or RF units. Grid lines for parking can be resized, moved, or switched off, and the picture can be flipped and adjusted for brightness and contrast. Wiring to the reversing lights turns the camera on automatically when the vehicle is put in reverse; wiring instead to a lighter or USB port keeps it running whenever that port has power.
