    Is ZoneMinder still being actively developed?

    I've been using a second screen (on modern gnome) and the Montage feature of ZoneMinder in full screen Firefox. As long as you want to watch the same cameras all the time it is fine. One feature it lacks is cycling between cameras and cycling to one that has an alert, but I'm OK without it.

    PoE surge protection.

    Thanks for sharing. I guess you're an example of someone having pretty good SPD setup. I'd also love to hear of experiences of people with less than ideal setups. Hopefully living in places with lots of lightning and highly charged rain. To explain what I mean by highly charged rain consider...

    PoE surge protection.

    I'm leaning towards the understanding that shields acting as a giant antennas picked up a nearby lightning strikes. Perhaps the shape of the cable influenced why some cables were affected and not the others. I'll be testing grounds and redoing rj45 on the switch ends to have the shields...

    PoE surge protection.

    Thanks. My grounding setup is a bit complex. Initially all 3 buildings had their own grounds. Then the house and the closest building grounds were connected together with direct underground wire. So they are now one ground. Building no 3 is separately grounded. I might change this in future, but...

    PoE surge protection.

    Thanks for answering . I have good grounding where switches are located(in all 3 buildings), but there is no grounding where cameras are. I have used foil shielded wire just in case I need it in future, but I haven't got the shields connected at camera side (the Poe adapters don't use shielded...

    PoE surge protection.

    I have a system with 10 cameras and 3 L3 managed PoE switches (cheap Tenda TEG5310P). One switch is installed in my house, it has 4 cameras connected via cables that go out of the building and are run on the edges of the roof overhang. 3 have these tiny PoE 48V to 12V adapters and one has...

    Weird glare visible at night.

    And the mystery is solved!!! I replaced the red plastic diffuser (pictured below) taking one from another unit and the problem went with it. By this I mean the camera on the pole can see a great picture, while the new one that has the old diffuser now has this glare. It looks like this In...

    Can anyone recognise this camera?

    I did manage to get root on that camera by dumping nand flash and replacing root's password in /etc/shadow. Also one can enable telnet by sending the camera this command via the web: tlctrl (so the entire path is http://cameraIP/cgi-bin/hi3510/param.cgi?cmd=tlctrl ). But, the main reason for...

    Can anyone recognise this camera?

    OK, I'll reply to myself in case someone lookinh for this info finds this thread. The camera is a generic SSC338Q+IMX415 like this one It seems to be a newer model of the Sigmastar+IMX415 camera module sold in few places on Aliexpress and it supports loading custom firmware through the method...

    Weird glare visible at night.

    I haven't tried moving it. I tried swithing other nearby cameras off to make sure it is not getting any IR shine into it(there is another camera a meter higher on the same pole). I also tried pointing a PTZ camera into its field of view at night and I tried switching off its IR illumination, but...

    Weird glare visible at night.

    Sadly it didn't help. I finally got a huge ladder, got up there and I cleaned the front with iso alcohol. During daytime it looks great, but the glare is present at night. Also I had a good look at the lens. I can't see any condensation or anything else inside. I think I'll have to send it back...

    Weird glare visible at night.

    It isn't. It is this style(with antenna removed and sma connector terminated): The case is metal and it is glued shut, except a small gasketed port at the bottom. Perhaps the seal there has rolled as was said. The entire front is a transparent piece of plastic with a hole for the lens and on...

    Weird glare visible at night.

    I have a number of the same type of noname cheap 2.7mm imx415 cameras. All but one are perfectly fine. One, installed recently has a very weird issue. It has some sort of "glare" on one side of the image. It leeks like the ir illuminators is hitting some dirt/grease on the inside of the lens...

    Is thermal right for me?

    For anyone interested as we're also talking about nigh performance of visual imaging sensors here. I checked the Dahua cam from 2019 with the 1/1.2 4MP sensor (IPC-Color4K-X, IPC-HFW5849T1-ASE-LE) and here in the EU it still costs $330. Ouch! This is pretty much what I paid for the thermal...

    Is thermal right for me?

    Sadly, the slider in the camera web intetrface goes from 1/1000 to 1/100 and then immediately to 1/10 (but has hundreds of settings between 1/1000 and 1/10000) So I was able to test only at 1/100 and 1/10. Based on my testing I believe the Auto setting is somewhere around 1/15~1/30. The image at...
