I'm gradually updating my domestic cctv system. We are in a relatively remote rural location and have internal and external POE Hikvision cameras connected to a NVR. One of the internal cameras has become erratic and unreliable. I've checked and the problems are definitely with the camera and not the cabling. It is a DS - 2CD2532F-1. It is in our main, large living room. When working reliably the camera served its purpose well with adequate coverage of the room. I would though prefer to replace it with something better. It needs to be unobtrusive and this puts me off the white light Colorvu options and turret cameras. A 2.8mm fixed lens seems best, but I am no expert. I will appreciate any suggestions as to a current suitable alternative. I have looked across the Hikvision camera range, but it is a little daunting given my limited experience. Thanks.
