I ordered 2 of these security cams. The first one set up and installed exactly as it was supposed to. The picture quality is excellent—I can zoom in on faces with nice clarity if necessary. The night vision also works well. The motion detection is very sensitive. I made the mistake of having it on high when I first put the camera up. ANYTHING that moved would trigger it (someone walking on the sidewalk across the street, cars going by, etc). Once I set it to low sensitivity, it settled down a bit. It is still sensitive enough to do what I want it to do. Now it just doesn’t pick up people across the street.The second camera would not pair no matter what I did. I contacted K&F Concept and after the obligatory “did you do this? Did you do that?”, they sent me a replacement. It arrived in 3 days. I charged it up and it was as easy to get online as the first one.As I mentioned above, I judge a company on their “recovery strategy” when things don’t go as planned. K&F Concept was great. They were pleasant and took good care of me. I’m sure the non-functioning one I got was simply a fluke and they stood behind it.I’m very impressedWith both the cameras and the company.
