That was my thinking as on the long run the infra red lights up but after a few seconds it switches off. I also read a topic "http://www.cctvforum.com/viewtopic.php?f=6&t=55474" that says that may be the ports are not allowing data and or power. (Im unable to offer a live url as I'm turned off by default and cannot see how to turn it on). So what sort of power would I be looking at. If I was to get another I would be looking at an 8 port POE and 1 uplink as I add further cams.

I have five hikvision cameras two HiWatch IPCD 120, two DS-2CD2032-1 cameras, and one DS-2CD2142FWD-1 cam and one switch BV-Tech 5 Port PoE Switch (4 PoE Ports | 1 Uplink Port) – 65W – 802.3af – POE-SW501. My query is that this one is working DS-2CD2142FWD-1, on a medium length cable approx 20ft. but none of the others will work on long length cables approx 60-100ft, but they will work on a three foot cable. Could my switch not be powerful enough for the long runs. I have checked the cable and both ends are in line as per cable tester wires 1-8 all correct at each end. On the short cable I can talk to the cams via the iVMS-4200 app and via the web app on the ip address. Just cannot get them to work on a long run. Any help or options, or power requirement options.
