KASIONVI 2.4g Wireless Color Video Transmitter and Receiver for the Vehicle Backup Camera/front Car Camera

The proximity must be within a couple of feet and minimal vibration to get a video signal about 50% of the time. BW video works better about 75% of the time. I could never get it to display a consistent static free video. I have this hooked up to a truck and they transmitters are about 18" apart, but any vibration or movement of the vehicle will cause the display to flicker and give a "no source" message. Better to wire to directly an not waste effort trying to get a stable connection.

Failed after 2 days. 2nd one from same company intermittent

Works well, better than my old one that came with my backup camera.

Might be defective. Picture is good at first, then static, then fades out within 20 seconds.I double-checked all connections..moved the location of the transmitters..nothing worked.In the end I ran a cable from front to back of my Prius. It would have been easier from the start.And a direct connection made a sharper picture.
