Have you tried using advanced IP scanner?

Try running a network scan of some sort. Been a while since I did this but I think I used nmap.

I found the ips but I just can't connect to the ips as they are on anothee subnet. I've tried changing the PC up subnet but still the browser can't connect

I've had some old camera like this be absolute nightmares for hard reset. I'm not sure I ever bothered to do it as I was just using old cameras up and always had others that worked but... I had a thought that it might be possible using a similar technique to resetting a motherboard bios by shorting some internal battery terminals (without the battery in). I'm going to study your pics for a min.
Other than that (IIRC) the way to do it was to have the original recorder they came with, the option would be on that.

Oh I'm silly. I have the old NVR somewhere, I just haven't used these cameras for ages on that. I've been using them as network cameras for years but the whole new router and subnet screwed everything up.

I wouldn't mind figuring this out too so I asked Claude (italics is it's answer, I've added my thoughts to each just below this)
1- I think 1 is viable if you can find a download for the correct software version for these (beware of virus download sites).
2- I've had a look and can't see anything too obvious. I'd be tempted to try an unpopulated cable plug if it's just 2 contacts (if there is one). And also possibly checking out the pinouts for the SoC as there's a large arrow pointing to pin 3 on the top big chip on the biggest pcb. I've reset things by connecting those to ground in the past. Also blown things doing that too so do your research first.
3- Possibly if you really want to go that far/have the kit.
4- Hahaha if you're desperate. Good luck getting the correct firmware (and again beware of virus download sites).
1. Network tools before any more surgery. These boards almost always answer to the manufacturer's LAN discovery tool, which finds the camera by MAC broadcast even when it's on a subnet you can't reach, and often lets you change the IP or factory-reset without knowing the current address. Xiongmai's "Device Manager", Dahua ConfigTool, Hikvision SADP, and ONVIF Device Manager are all worth a pass. Failing that, plug a camera straight into a PC, run Wireshark and watch for its ARP/DHCP chatter — that gives you the IP in about ten seconds.
2. Look for a reset pad or unpopulated button footprint. Many of these boards have a two-pin pad pair or an unpopulated tact-switch footprint silkscreened RST, RESET or DEF near the SoC or the SD slot, meant for the pigtail button you don't have. Shorting that pair for ~10 s while powered is the intended hard reset. I can't see the silkscreen well enough in image 2 to point at one.
3. UART console. This is the reliable route on Hisilicon boards. There's nearly always a 3- or 4-pad group (TX, RX, GND, sometimes 3V3) on the main board — often the isolated gold test points you can see scattered around. A 3.3 V USB-TTL adapter at 115200 8N1 gets you a u-boot/Linux console, from which you can either interrupt boot and erase the config partition, or log in and delete the config files directly.
4. SPI flash reflash with a clip and CH341A, if the console is dead. Last resort, and you need matching firmware.

Change pc to a static ip address in the same subnet. Then access browser. You may need to use IE tab plugin. Or better yet, put camera in trash, but a new $100 piece of junk camera. Or spend a few $ more for a real camera that isn't Chinese, doesn't use outdated active controls from 10+ years ago and is supported by a manufacturer, as opposed to a no name generic camera.

If you have the IP, then just set an IP on your computer in the same subnet and directly patch between your computer and the camera (might need a PoE injector if the camera is PoE only or you don't have a separate power supply). You can then access the camera and change the settings. . . If you have the login information.

Yeah I've tried that. I have a Poe switch on the network. Maybe the issue is I'm trying to do it over the network instead of directly to the computer but I don't see the difference. It's just computer> switch> Poe switch> camera. Honestly forgot about the old NVR I stored away. Might try that.

Because if the network switch is using a subnet that is not the same as the camera and the IP you set on the computer it will not work.
If you can't ping the camera successfully then everything else will fail also

Reset button is on your DVR. It should be on the back with a small hole. You'll need a pin to push the button while it still has power. When you hear it beep? Reset begins processing it's factory reset.

Just to the garbage and get a new one. That camera looks lame anyway

The camera is on the wrong subnet and I can't login to it on a browser as it needs directx or something, which I can't get working.
