The Micromark MM80111 Wireless Black & White CCTV Camera Kit is easy to install. Just a case of plugging everything in then matching one of the four channels on both the receiver and the camera for the best picture. Don't do what I did and screw the camera to the wall first as if the picture is terrible, you have to take the back off the camera, and switch little jumper switches to channels 2, 3 and 4 to get the best image on the TV. I would have thought maybe an external switch would have made more sense!
Once we got a stable image, the quality of the camera picture was not bad. We can definitely see what is going on in the black spots of our shop. The only big let down with this kit is that is susceptible to interference from mobile phones, and as everyone carries one now, this is a bit of a pain. This is more so if someone is using the phone, or if the Bluetooth is activated on the phone. The picture will roll, then go of and come back again.
All said and done, it is a deterrent, and we can still see if any wrong doing is going on in areas that before were hidden.
A good, affordable kit, but the signal strength is weak.
