I bought a door viewer recorder recently so that I can record who loiter outside my house. Before I bought it, I checked for the viewing angle. A Singapore company charged me $250 over dollar for the camera with a viewing angle of 70 degrees and not recording function. I found one in eBay with a viewing angle of 165 degrees and with recording function, at USD 92 only.
After I installed the camera, I realised that I missed out these points
- The sensitivity of the auto-detection. It turns out that my can detect movement up to 1m away.
- How sensitive is the auto-detection. Not so good, there is a delay and if anyone is outside try to cause a mischief, the camera may not catch him if he moves off very fast.
Do take note when you buy this gadget.
