No complaint on the BNC coupler, it work just the way i wanted it to work, it convert my Revo RJ12 camera to BNC line to connect with TVL DVR. Work very well, but the power adapter is too weak and small, it would power the camera for 48 hours then it stopped. I have to unplug it and plug it back in again.I end up purchasing another 12vlt power adapter for $20 from Revo. I guess this small 12v is only for small dome, turret, and bullet cameras.
