I have been struggling with a camera in one location for over a year. The camera is a Everest EV-IPMB4T36, which is a rebranded Dahua 4mp 3.6 rectangular bullet, larger sized camera with 4 high intensity IR LEDS in the 4 corners of the camera face. The Cat 6 was originally run for an older 1.3 mp Dahua bullet long since replaced, which had no problems with image cutout. The camera image intermittently cut out, mostly at night, starting over a year ago, but would illuminate the IR at night even when not sending an image. Despite the recommendation that I do not replace the camera by my vendor (HD Security Store/HEI-vision out of NY) I did replace the camera approximately 8 months ago. This did not fix the problem, and the old camera installed in a new location works fine.
The camera is mounted on the top of a roof, and is a difficult install with a custom mount, etc, but even more difficult is the 70 Ft Cat 6 run, which runs under a new metal roof. I do have some L-Com lightening arresters inline in an wall mount enclosure at the outside wall penetration, but bypassing the arrester makes no difference. I used to be able to get the camera to work for a day or so, if I manually restarted the camera either by disconnecting the Cat 6 from the POE injector (originally an L-Com injector, but more recently a Unifi USW-pro 24 in a POE ++ port) or cycling the switch port (when using the Unifi POE switch). Now a restart only gets the camera running for a few minutes. As you can tell, I am trying to avoid what will be a very difficult new run of Cat 6. I just upgraded to the Unifi USW-pro 24-POE from a USW 16 POE switch because the latter only has 45watts total of available POE, while the new USW Pro 24 has 400 watts plus POE ++ ports. Needless to say the upgraded switch didn't help.
Any other suggestions before I tackle a new run of Cat 6? I was looking at the Platinum Tools TPS200C tester ($85)

to possibly test for voltage drop at the camera end of the Cat 6. Passive 24V setting on the switch didn't make anything more stable, but maybe I could push more watts through the line since it seems to work part of the time?
Any other suggestions?
Thanks in advance.
