    New Hikvision Hybrid Thermal Cams

    The camera is seeing its first sunrise. As I understand it, this type of thermal sensor (VOx) is "generally" safe to point at the sun...

    Oops. I hadn't properly finished the publish process on that one. Should be fixed now.

    For this clip, the optical module was set to 1/120 exposure. The thermal module doesn't have exposure settings in the traditional sense.

    Here are snapshots from the optical module at night. I have a big IR floodlight as well as several other IR cams pointing here. Though it is hard to tell viewing thumbnails, distant stuff does get clearer as the exposure time goes up. 1/500 exposure 1/250 exposure 1/120 exposure 1/60...

    Thermal cams are particularly good for motion detection that doesn't get false-triggers from shadows and lighting changes. Sometimes they are also used to monitor industrial equipment -- checking for overheating for example.

    I got it mounted outside. I prefer to keep the thermal video as pure thermal (not blended with optical) because that keeps it immune to certain false alarm conditions like changing lighting and shadows. Here are snapshots demonstrating one of the image settings, DDE (Digital Detail...

    Yep. My thumb.

    Picture-in-picture is available on Camera 01. You can move the thermal overlay around anywhere, but not resize it. Camera 01 offers 3 resolution choices for its main stream 1600x1200 you've already seen above. 1280x960 is the same FOV but smaller. 1280x720 is just the same thing...

    For the following video, I've set the noise reduction to "Export" with Space DNR 20 and Time DNR 50. I think the stock setting for "Space DNR" of 50 is too high and reduces perceived detail. I've set Camera 02 (the stream that includes thermal imagery) to Details Overlay mode which means it...

    Now I'll get around to some of the promised snapshots. The optical module is nothing special. On this -2 model, it is a 1600x1200 resolution and just slightly wider FOV than the thermal module. Here are various blend mode settings. The alignment is poor up-close, but further away it looks...

    Persistence has paid off. I started trying undocumented API commands, and it turns out there is one which appears to fully reset the DPC system and it fixed my camera! <?xml version=\"1.0\" encoding=\"UTF-8\"?> <DPC><mode>start</mode><dpcMode>auto</dpcMode></DPC> The secret is to set auto...

    Everything was fine when I unplugged the camera last night. But when I plugged it back in this morning with the intent to record some more video for you guys before installing it outside ... the 5 defective pixels I uncovered the previous night reappeared and the DPC (Defective Pixel...

    New Hikvision Hybrid Thermal Cams

    So far the main caveat of this camera is the thermal sensor recalibration that happens every few minutes. It makes an audible clicking noise that is just a bit louder than a typical IR cut filter, as it moves a physical shutter in and out of place in front of the thermal sensor. More annoying...

    I don't do anything halfway it seems. I didn't like the prospect of cleaning up my mess of good-pixels-marked-bad manually, because I knew I would miss some. So I wrote a program that uses the camera's API to clear the defective pixel flag on all the pixels, one by one. It is actually pretty...

    New Hikvision Hybrid Thermal Cams

    UPS came by at 9 PM and dropped off the camera, a couple hours after tracking said it was no longer out for delivery. I'm getting this thing figured out. There's a lot of customization that can be done for the thermal camera. One of the first things I noticed when I plugged it in was the...
