    [HELP] Formatted HDD Recorded from DVR AVTECH

    Most likely in Linux. My wife does recovery of different kinds of hard drives and believe the header just needs to be restored using a recovery program. We are in Southern California.
  2. I have been working with some Hunt CCTV IR cameras at a particular project where the picture at night looks extremely foggy (when there is no fog). On one of the cameras, I was able to get results by moving the camera up a wall 10'. I have not yet moved the other 2, but have temporarily replaced the Hunt IR Domes with Hunt IR Bullet cameras at same locations and the fog at night continues. I am trying to imagine what it is in the picture that causes the difference, when the domes I brought back to my place seem to work OK here. Is it most likely that I do not have enough IR? Too much IR? Too much contrast between light areas and dark areas? Hunt thinks that if I move the others (even a few feet) that I could resolve the issue. But I am looking for an overall rule for the future, as to how to avoid this issue.

    Night time looks foggy on IR cams

    I had thought that I had it. Got new dome covers, made sure they were pristine, set low light luminescence to .25, and there was still fog and picture was too dark. Looks like I have to move the cameras or it is reflection from the dome. Problem does not exist without dome covers on.

    Night time looks foggy on IR cams

    When they were at clients home, I focused during the day. When I am working on it at my place, I have focused at night and come up with similar scenario (focused at night). I might not have mentioned it before, but I temporarily replaced the domes at the clients with 79G Bullet IR cameras and the same fog effect occurs. So it cannot just be reflection off dome cover. Maybe reflection off a wall. But, again, when I brought the domes back here, I was able to recreate similar effect, that is worse with cover on, but is mostly remedied by turning down the low light luminescence seting from .75 to .25. I picked up Hunts better dome that is WDR and 650 lines in both an IR and non IR version that I hole to test here tonight.

    Night time looks foggy on IR cams

    The Hunt Domes have a spring loaded, circular separator between the IR emitters and the lens, so this is hard to imagine. It IS a little worse when the cover is on, but I found that by turning down the low light luminescence from .75 to.25, it seems to help quite a bit.
