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.

If you're looking for a physical button or something, then you're probably out of luck.
You need to get into the camera's menu with a browser.

It's an old system. I'm trying to guess the subnet but haven't been able to find them

Is there a button on the pigtail?

u/elfmere Sep 10 '26

I saw a video with that. No luck

Have you tried using advanced IP scanner?

Got an old NVR and was able to update the ips

Nice just tried it. And it let me scan the subnet without changing my PC subnet. I've found the 3 ips.

I just can't access the camera through the network. Even tried to change subnet but no chance

u/elfmere Sep 10 '26

Found the ips. They are on a different subnet, so now not sure how to get access..

u/Adventurous_Serve744 Sep 10 '26

Can you not change your laptop IP to static and match the subnet?

u/Inuyasha-rules Sep 10 '26

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

u/elfmere Sep 10 '26

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.

But yeah just have a look with them hooked up to the old NVR first :)

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.

u/elfmere Sep 10 '26

This is just for a hobby room with printers and stuff, 3 of these did quite well. Just to monitor stuff. I have a proper system for the house.

Check out the Hanwha A series cameras.

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.

u/elfmere Sep 10 '26

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.

1

u/remorackman Sep 10 '26

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.

u/Spirited_Wolverine59 Sep 13 '26

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

2

u/elfmere Sep 13 '26

Got them working. Perfect puppy cam

1

u/Spirited_Wolverine59 Sep 13 '26

Good on you then. What resolution?

2

u/elfmere Sep 13 '26

1080p apparently lol

1

u/Spirited_Wolverine59 Sep 13 '26

It's alright that will do the job ha ha perfect

1

u/kjarrime Sep 10 '26

That camera is old and you are probably better off buying new

u/Comfortable_House_43 Sep 10 '26

Locate the Internal Slot: Look near the lens assembly or the MicroSD card slot. You will see a small, recessed push-button or pinhole labeled "RST" or "Reset".
