Think one of my Dahua cameras is about to die?

Revo2Maxx · Mar 3, 2025

So starting at about 2am last night my camera went offline. It is a camera that I really don't get any traffic but is there incase I do. I have it setup with a Tripwire for human detection seeing it is watching an area where my Large BBQ is for doing a whole Pig and does have a couple of areas that someone could enter this area. It is keeping an eye on my Large Spit Motor and other then that it don't really mater. However I don't want the camera to die either lol. So I put in the log files that was sent to my log server and have this camera sending the logs to the computer. I have listed the log in a way to take out all the #012 that it normally looks like and have it in a format that is readable. Maybe someone that has an issue might be able to tell by the log what the issue is. I am not sure if this is the right format to enter lots of text but I put it in Code format on the forum to maybe not make the post look so long. On another forum it puts it in a text box that can be scrolled and hope that is how it works here too, If not sorry in advance as there is a lot of text.

Anyway if you have had a camera die, and seen text in the logs like what is seen here, If you were able to correct it before the camera died would love to know what you did?. I have the camera connected to a POE switch and I have changed the cable and the port that it is connected to. The issue only happens maybe once or 2 times a month. Most times I just notice it is offline and go do other things and when I return the camera feed is back. One time it was offline for 3 days. It was so cold out that I didn't care to go look. But was after it came back online that I made the changes to the POE port it was connected to and changed out the cable. It is Pure Copper cat5E and test good.. So don't think it is a Switch issue or a cable issue? I did check the POE port data to see if there was anything and there was some Errors but my guess that is caused from the camera and not the switches ability to move data.. If I log into the switch and I turn off the port and wait and turn it back on thinking that it would do a camera reboot the camera still fails to resetart. I didn't do that last night when this was going on. Or should say early this morning lol. Anyway if you see something that stands out to you would love to hear what you think . Also I just logged into the camera before I posted this and there is no info in the camera anymore about Sub Channel and did a Reboot and camera came back online but again there is no info about sub channel? Should I just try to reset it back to factory? Thank you for looking..

I occasionally have an outdoor camera that goes on and off line, and it virtually always goes back to connections. I had one a few days ago. Near the camera there's a waterproof box with a POE splitter and the various connections for it. They were all clean and dry and I saw no signs of corrosion. Just from prior experience I removed and re-plugged all the connections a few times and closed the box up. The camera has been solid since. From the log, it looks like it recorded "hot swap" when it went offline, then "start up" and "abort", in either order, when it restarted. I wouldn't have a clue what the hot swap is about. I have had some real camera failures, maybe one every 3 years out of 16 cameras.

Hotswap has to do with microSD most times my systems in critical areas will have them for backup to nvr recorded footage. Normally for me only have issues when card fails. The system will log hotswap from a working state to 0 none working mode.

Area covered in poison ivy but guess have to clean out and swap the camera on next warm day.

Thanks for looking

Yep the HotSwap is usually related to the SD card. Either a problem with it recording or failing. A re-format usually gets it going again.

Well went and looked after another offline and I changed from h.265 to h.264h to see if that would do anything and today both streams are back.

So did a reset of the camera, camera came back online and back to h.265 so it defaults to it, so I leave, if go offline again I go put a 8mp turret there. Haven't even used the area in 4 years lol

Think one of my Dahua cameras is about to die?
