I have a Sinocam IP-camera which was connected to a Huawei b593 4g router, until a supposed computer engineer fiddled with the cameras settings and rendered it unusable. The camera ships with a static ip address of 192.168.1.100, but does not respond to pings on that address any more.
The camera is connected to the router with an ethernet cable, I have tried several cables to exclude cable problems.
After sending an email to the (chinese) producer of the camera asking them for help, I got a reply that said (quote):
Please change your PC with fix IP address and add 192.168.5.xxx, 192.168.1.xxx
I think they mean that I should put a static ip address on my computer and then I should be able to connect to the camera. I have tried but it does not work.
I have tried nmap -sP 192.168.1.0/24
and nmap -A -T4 192.168.1.*
but the camera does not seem to be listed.
How can I troubleshoot this?
There is no reset button on the camera. The email from the producer tries to explain how to reset it by using telnet.
I tried the camera on a different router, but everything still behaves the same. The camera does not show up on any of the routers 'connected devices' page.
I tried to connect to the camera by setting a static ip on my laptop and connecting them directly with an ethernet cable, but I got no response from the cameras static ip address or from nmap.
I tried again to connect to the camera, but it did not work. What I tried:
- set my ip to static 192.168.1.14
- reboot
- connect camera directly to computer with ethernet cable
- execute
nmap -sP 192.168.1.0-255
-> only my computers address showed up - execute
telnet 192.168.1.100
-> 'could not connect'
I tried once more to connect the camera directly to my laptop, but it did not work. Here's what I did:
- Purchased a twisted network cable and connected my laptop and camera with it
- Set my laptops static ip to 192.168.1.13, I also tried 192.168.5.13
- Performed nmap, ping and telnet commands in cmd to no avail.
I'm at a loss here. Maybe the camera is just broken.
tcpdump
to try to infer its settings based on what it sends out.
