Hi guys, here’s an interesting one. I have a Swann 4K nvr system . I wanted a closer field of view on one of the cams so I bought a 5mp 16mm lens . I swapped it in , set it up & refocused it etc & it all worked well when I had it close to the nvr , ie a 5m cat6 cable ( not swanns cables). When I set it up at the location I wanted it at some 50m away , it won’t work . No image . Nvr doesn’t say offline either . I tried reloading factory defaults for the cam & tried rebooting the cam but to no avail. Other cams work ok at that distance. Any ideas ? Cheers
