My client has several of DH-SD5A225XA-HNR 25x AI PTZ domes and some of them seem to have occasional reboots. In the log there is reboot mark: abort.
This can happen right after IVS has been triggered and tracking has been started, but also when there is no events triggered (nothing moving in the image).
Camera has Dahua 128GB SD card in, cotinuous record on and IVS record also when triggered. Power source is PoE switch.
I haven't seen the physical installation but in one camera the problem stopped when the camera was moved to different place and another cable was used. It turned out that the cable was too
thin (27AWG) and probably Poe voltage dropped too much. After that he has used various cables and some time this problem has been away for long time, but then it just appears again.
I have suggested to test +24VAC directly, but client wants to use PoE.
I have also asked directly from Dahua, they told to update firmware and do factory reset. Well, that has been done.
Anyone else has these symptoms with these SD5A***XA-HNR PTZs?
