Check FPS and key rates/Error 8000ffff
I have deleted it and reinstalled it, now I have a No signal - Error: 8000007a (Check Port/User/Password)0 Camera works in GUI(though since no NACL support I don't have video in GUI). -
Check FPS and key rates/Error 8000ffff
I have tried switching ports, and even good working camera cables to that port, with no change, I guess you are right. I have tried this camera/cable to use a working port and it still did not boot up(no image). Maybe the camera is dead?! I will investigate it soon. The weird thing is that now I... -

Check FPS and key rates/Error 8000ffff
It was under network, that is why I couldn't find it. Ok, that worked for the 8000ffff error code. I still have the "Check FPS and key rates error" on. Thank you wittaj, you are the best!! -
Check FPS and key rates/Error 8000ffff
It is my first camera, an old Chinese market HFW4431R-Z. In the BI I don't even have a video image, the plug-in doesn't even work anymore, but for the side alley it is an OK camera. If I adjust something on it, I use UI3 to view it. Where can I find the ONVIF authenticator? I can't find it, I... -
Check FPS and key rates/Error 8000ffff
I have this exclamation sign on this camera, which I haven't encounter before. Do you guys know what could be the problem? iframe is the same. It used to work great for years. Lately, I had a bad memory leak(just memory, cpu was low), it was increasing the usage as I was watching(over 4GB)... -

Troubleshooting Circuitry in Old SD49225T-HN PTZ Cameras
Great job! I'm surprised, how come that battery is not a super capacitor? In a Fluke meter they use supercapacitors. I have just replaced one a few weeks ago, in a 189. It started to corrode, some start leaking after a few years, and can seriously mess up the board. When you buy electrolytic... -

I have never repaired one of these, just basic cameras. -
Troubleshooting Circuitry in Old SD49225T-HN PTZ Cameras
That little "battery" looks almost like a super cap, that I have just replaced in my Fluke 189. With the thermal gun, you did not notice anything red hot? Like an SMD capacitor? I have found in the past shorted SMD caps, causing the IR to not work. Greta job, of working on these. When I have got... -
Someone on eBay has a bunch of Dahua SD49225T-HN cameras
The auto tracking wasn't great on these. -

You don't have a thermal gun by any chance? Maybe that would show something overheating. -
Troubleshooting Circuitry in Old SD49225T-HN PTZ Cameras
It is not enough to have their value, they have an ESR value as well, and you need an ESR meter to check that. That value could be much higher than a new one. Did you replace the 47uf one? If not, maybe you should. -
An Awesome Camera
Believe me, the extra IR lights will produce a way better image, than the camera can provide. -
An Awesome Camera
I have this for narrow angle(LPR purpose), but you can get one for wide angle. It is great light. It's been running great since 08/19. https://www.aliexpress.us/item/2251832631327435.html?spm=a2g0o.order_list.order_list_main.317.21ef18028zY0l1&gatewayAdapt=glo2usa4itemAdapt -

You should install some IR lights on the barn, then you will have way better images. -

Camera reliability?
I have a Chinese 4431-R-Z(my first camera/didn't know any better then) since 2017 and it still runs well. It is under my garage eve in LA, so temps are high here. -
Thin vertical line, what is it?
If not the monitor/TV, then maybe a ribbon cable inside the camera?! -
Smallest Auto-Tracking Camera
The smallest is most likely the SD49225XA, which is not small, around 11" tall. -
Dahua SD49225XA-HNR Auto Tracking Enabled Firmware.
I have two network ports/cards on the PC(one for Windows-updates, and the other no internet access-just for cameras), use Asus router OpenVPN and on the phone, I use UI3. P2P disabled on the router and on the cameras. -

This is why it is a good idea to restrict internet access to the cameras. -

Hardware repair of DH-TPC-SD8620N-B50Z30
You don't have a thermal camera? I would power it up and inspect it with the thermal to see if anything start heating up. Otherwise, I would start measuring components around the input where you added power. Measure across smd capacitors with the dmm beeper, to see, if it has a short. -

It does not have a 12V plug? It won't turn on from that supply? -
Dahua PoE failure rate
For sure they have changed. In 2008-2010 Samsung TVs were going bad because of capacitors, were bulging. -
Dahua PoE failure rate
Yes, shorted smd caps. I have just fixed a JVC Dila-X500 projector, that had a shorted smd cap in the ballast daugherboard. I have fixed quite a few other devices in the past, even security cameras, that had shorted caps. -
Dahua PoE failure rate
I'm 90% that some capacitor is shorted. Check those brown capacitors. The black ones are resistors, and those two big black ones are inductors(those will show short). -
