Glad to see you can chime in on this Andy. A lot of guys buying here are DYI home owners and small business owners and are looking for a good camera at a discount price. I think as a business owner yourself, you can understand why the end user just wants things to work, in my case, people or as you say RiCh GUYS are willing to pay the little extra for good service and good support. I depend on my re-sellers to support their product. It seems you do pretty good here just doing that, keep it up. Most amazon or ali sellers are are of little help when things go wrong, i have experienced this first hand and have stayed away from them for just that reason. Judging from the amount of cameras you sell here it would seem you do your best to keep they guys happy here. I have even considered trying some of your stock and see what happens.

Aliexpress seller has responded to me asking if i have upgraded the firmware on my camera. I think they will just say that i upgraded the firmware and killed the cam (maybe i have 
) Think i may have jumped the gun a bit by trying to get the camera working when it first went down and maybe i should have left it as it was for a while as it seems most people have got theirs working again.
) Think i may have jumped the gun a bit by trying to get the camera working when it first went down and maybe i should have left it as it was for a while as it seems most people have got theirs working again.Problem is related that dms.dahuatech.com server died and camera has bad workaround for this error. So the main process dies and then camera reboots.
To fix it for temporary - set DNS both servers to non-existing ones and wait for a fix.
Also - DONT TRY TO UPGRADE camera when it has internet connection BECAUSE in the middle of upgrade process it's watchdog hardware will reboot it and you will get a brick with only possible way to recover will be to use UART and TFTP method. I warned YOU!
Below are logs from DH cam when it dies - this is what happens.
So stop fighting with PSU, POE, power, ethernet cables, cabling. It's not you fault. Just wait or if you have knowledge - just set DNS to non-existing ones (both) or disable access to internet from cameras on router.

No need to - just wait day or two.
I can't even get anything out of the camera though
I can't get into the web interface and the camera no longer does the clicking sound when it's rebooting. I used to have a green LED light that came on on the PCB but even that doesn't come on now.I did during the second day of it not working. It says that the firmware upgrade completed successfully and rebooted, ever since then it's not worked. I can still get the camera to ping on 192.168.1.108 and it ends up losing pings and then it pings fine again so the camera is not completely dead but i'm guessing the firmware upgrade has something to do with it not working and most likely bricked the camera.
I've just looked on here at that method. To be honest i don't feel very confident trying to do that. I think i might just have to pick up another camera to replace this one.
I've got the same issue where the cam reboots when connected to switch that has internet connection, funnily it's only 1 out of the 3 dahua cameras that does it. In the meantime I have just connected the camera directly to the POE port on the NVR and it works fine

one more time - changing password won't help at all. This is not hack, this is not backdoor. This is just poor software inside that needs to be fixed. Change DNS or disaable access to internet - no incoming but outgoing. You can drop just DNS (port 53 UDP). It will fix it.

What is the purpose of the cameras contacting dms.dahuatech.com?Problem is related that dms.dahuatech.com server died and camera has bad workaround for this error. So the main process dies and then camera reboots.

My guess would be for bar scan code to make it easier for customer to link their camera to the app on the smart phone without having to find the ip address and port the camera is on outside of home network.
