Cannot find IP CAM

Hi,

I bought a Dahua IPC-HDBW4231F-AS. I have connected the cam to my PoE switch (Ubiquiti) which is connected to my modem/router. I cannot find my camera with the config tool.

I've tried using an IP adress in the same subnet, but I cannot manage to detect the camera (it is working, as the IR leds are glowing).

Can anyone point me in the right direction? Thanks!

PS I want to use my Synology 718+ as a NVR.

Make sure your computer is on the subnet of 192.168.1.1. Then using Internet Explorer, go to 192.168.1.108.
If that doesn't work, while cam is powered on, press the factory default button for 10 seconds, wait 3 minutes, then try again.
 
Hi, thanks.

I connected my laptop to the switch, changed the ip to 192.168.1.1 (in network adapter > properties > ipv4 settings > set static IP). But still I cannot find the cam.

Where is the factory default button?

Thanks again!

If you entered that IP address, my $2 bet is that you have nuked the router's internal gateways address - normally your router is on 192.168.1.1.

Tell us a bit more about how this ubiquity is configured? Don't you see actual "power consumption" in the gui? it should (at least) indicate that something is connected to port #

Hi,

It shows up in the Uniquiti cloud controller. And the power consumption is displayed. The camera's IR leds are also on. So the cam gets power.
My ISP modem is also the router and is assigned with 192.168.178.1. I changed this to 192.168.1.1 as well as my computers IP (same subnet). But still can connect to the cam.
Will try to reset the camera tomorrow and try again.

Is it possible to access the camera if connected to the switch? Or do I need to plug it in my modem/router. In that case, I need a PoE injector, because my modem/router does not support PoE. Right?
 
Should work if the computer and IP Camera are attached to the same switch, even to multiple ports on your internet router, or even if connected directly (computer directly wired to camera over a simple ethernet cable with nothing inbetween) if you set the PC ip address to the correct ip/subnet (manually), and you can power the camera a different way. I wouldn't buy anything new though, so if you only have POE switch to power the camera, you should be able to get it working connecting the computer to the same switch as the camera.
 
Hi, I reset the camera. Hooked my laptop up to the same switch, assigned the 192.168.1.1 (via IPv4 settings) IP to the laptop, but still I cannot see the camera...
Any more ideas? Thanks!
 
Can you ping 192.168.1.108? What does the Ubiquiti controller show for an IP address?

Try to set your PC to something other than 192.168.1.1, use 192.168.1.110, just anything other than the 1.1.
 
I'm with bob2701 on this, if you are connected to a switch/router then the likelihood that it would be at address 192.168.1.1 is pretty high. If you are ARE NOT CONNECTED DIRECTLY (with no other device in-between) with a short ethernet cable, try something more like bob suggests for your PC IP address.

It's possible the PC is both conflicting with your switch and also thinks itself the primary gateway and since it cannot see the camera it assumes it is unreachable. If the camera is hooked to the switch then the switch is very likely able to reach the camera, and if the PC sends the request to the switch it should be able to establish a connection barring any significant hardware/wiring issue.

Some of this could be obvious if you tried the following from a command prompt on the PC:
  • PING 192.168.1.108
  • TRACERT 192.168.1.108
If your computer is 192.168.1.110, you should see it connects first to the default gateway (probably 192.168.1.1) and then to the camera itself.

Check the settings in the config tool and see if it looking for the proper network ip.
 
I've set the IP for my PC to 192.168.1.110.
Both with ping and tracert I get: 192.168.1.110: destination host unreachable.
Ubiquiti switch is set at DHCP.
 
 
what are you using to power the camera. If it is a power wart change to a different power plug.
If you are using a POE switch, try a non POE switch and a power plug.
How far is the camera from the PC ?
Are you using store purchased cables. NOT your home made cables.
 
Can you do an IPCONFIG on that computer and check the default gateway on the network interface to which you have assigned the 192.168.1.110 IP ? I would expect it to be 192.168.1.1. I interpret that destination host unreachable as the PC doesn't know where to send your request.
 
So to recap, you changed your router from 192.168.178.1 to 192.168.1.1 correct?
If so you should not have to do anything else to see your camera. Your pc should be on the same subnet as well as the camera as long as your cables are good and the camera has power.
Which Ubiquiti switch are you using?
 
Hi, I did not change the router (=ISP modem) IP adress, only that of the PC connected to the same switch as the camera. See image. I'm using this switch: Ubiquiti Networks - UniFi® Switch 8
IP of the switch is in the range the modem assigns (192.168.178.xxx).

My guess is you don't have any way to power this camera except via the POE switch?
  • Try ARP + Dual IP Interface method
    • revert your network back to default working condition(192.168.178.1)
    • arp -s 192.168.1.108 00-1E-8F-46-80-2e (<-- your camera hardware address here, might be optional I didn't try without this step)
    • Change Network Adapter settings, add 192.168.1.1 subnet: 255.255.255.0 as a secondary IP under Advanced for that network interface
    • ping 192.168.1.108
    • (if it works) connect to the camera at the 192.168.1.108 IP, change the address from 192.168.1.108 to 192.168.178.X you want
    • find and turn off the "Enable ARP/Ping to set IP address service" in the camera settings
  • Manual Way
    • Buy a POE-to-12VDC adapter with the correct size DC barrel so you can direct connect all future cameras
    • Manually connect network cable from PC to camera with unknown IP (in this case default is 192.168.1.108)
    • configure the network interface on PC with Manual IP of 192.168.1.1
    • ping/test connect to camera
    • login to camera and change camera IP to 192.168.178.X you want (camera will reset)
    • revert your PC network adapter settings back to normal
    • plug camera and PC back into switch

So this "switch" who is distributing DHCP addresses (I never saw one, routers are usually doing this) is distributing it in the range of 192.168.1.x ? Otherwise your setup won't work.
