Dahua Camera rebooting once a day or other day

[houmi]

Hi Everyone,

I have a 6 Camera system, they used to be powered via NVR that had built-in POE switch but right now I am using a tp-link poe switch since I upgraded the NVR to one that didn't have a POE switch built-in. But about once a day, or once every 48 hours, one of the camera reboots on its own (I see Abort/Startup in the log), there is no SD card in it.

The POE switch is this one:

https://www.amazon.com/dp/B093Y147Q5

It is unmanaged so I don't get anything about power usage and such, as far as I know the cable has been fine and it is somehow closer distance wise than some of my other cameras which are fine, and I was wondering what I can do to pinpoint / debug this issue.

Start with a short cable 3-6ft at the NVR/desk. test for 24-48 hours

What model camera is it exactly?

Does it happen to another camera if you plug a different one into that port?

the Model is N42BJ62, I'll swap cameras on port #1 & #2 of the POE switch (the one on #1 is having issues) to see if it is a POE switch related.

I might have to take that camera off as well and try it closer at my desk. Good call!

If I'm not mistaken thats an older Lite 4MP with a crappy 1/3 sensor in it. Might be better off just replacing it

make sure Smart Codec and H.265 are OFF
use General codec and h.264.h

Yeah I plan on upgrading my cameras at some point, I just upgraded the NVR, but will probably get the IPC-T58IR-ZE-S3's next.

mmmmm you may want to rethink. The 58xx is not going to do as well as the 5442 4MP generally speaking. It needs over 2X more light to even get close.

Dont chase MP. Look at some video samples here on the forum

Do you have a link to those ?

By the way, this was it... thank you!

I have 6 cameras and all are on h264 but that one was on h265 , and switching it to h264, it has not rebooted in a few days.

30 watts(802.3AT standard) x 8 ports =240 Watts. POE max is 124W...
8 x 802.3af 15watt cams would need 120 watts.
you could be hitting your max available power.

Thank you, when I was looking at my Camera specs, it had them listed on Dahua's site as : < 6.6 W per Camera.

The Switch has a POE Max of 124W like you mentioned. I have 6 Cameras, so shouldn't be plenty ?
