Reset NVR and Cameras now not showins

[samnorman21]

Hi Folks,

I recently bought a house with a CCTV system that had been monitored.

I accessed the system and could see all the 8 cameras active yesterday, but could not access them directly on the app, so did a factory reset. My NVR kicked back up, I added a new password etc but now all the cameras are showing as offline

Any ideas what i can do to help bring the cameras back online?

My NVR device is DS-7608-NXI-12/8P/S
They cameras are all connected via as single ethernet cable which is connected with a POE Injector (I am not technical so may have got wording wrong).

The NVR shows up on my home router page http://192.168.0.1/ but cameras do not.
The cameras not showing on SADP, but can be seen on the config page (screenshots attached).

I suspect my cameras just aren't on the network, but no idea how to fix. PLEASE HELP

You've reset the NVR but the cameras are also password protected. Ideally you need to change the admin password of the NVR to what it was previously so that it can access the cameras and connect to them. If you don't know that password, unfortunately you're going to need to factory reset each camera individually. Depending on the model the camera may have a reset button that you can use; that's rarely convenient as you have to get to the camera to use it.

The 8 x POE ports on your NVR are in a separate, totally unique network (or "Broadcast Domain") from the LAN port connected to your home network.

The NVR does NOT copy (or "route") Ethernet packets from the 192.168.0.xxx network (your LAN port) to the 192.168.254.xxx network (8 x POE ports) or vice versa. The NVR is not a Level 3 switch or router.

To see your cameras on the 8 x POE ports, free up 1 x POE port, plug your SADP tool into that empty port, and re-run SADP. You should see the other 7 cameras still plugged in.

Too early for me to say why the cameras aren't seen by the NVR. I'd expect them to be there. Something else is going on. Plug & play vs manual configured ? I dunno. Provide a new screen shot of SADP (run from a POE port on the NVR) & maybe someone can help further.

EDIT...... JB probably nailed it with the password concern.

Hi, The way the system is wired there is only 1 POE used to connect with the NVR so lets of free ports to connect into.

When I plug my laptop into the NVR, then what do I do? Just run the SADP app or something else? Thanks In advance

Just run the SADP tool on your laptop....... with the laptop plugged into a spare NVR POE port.

IF you use the LAN port you'll get significantly different results. Be sure to re-try it if you wish.

Post a clear screenshot from SADP (but to avoid confusion for the inexperienced, please do indicate which port the laptop is plugged into. Other people read this post too)

1 x cable plugged into an NVR POE port - AND you have 8 cameras hung off that - doesn't sound good, performance wise...... BUT with low res cameras maybe it can work. First things first though..... get your cameras connected/working.

Thanks! Realised it’s 6 not 8 cameras!


See attached the screenshot, I was plugged into POE 4. The cameras do at least show up so that’s a start…

ok, seems at one point the configuration had 8 cameras. But now you have 6.

The is my best guess, since all 6 cameras are connected to 1 x NVR POE port:

1. figure out the full IP addresses for all 6 cameras. Extend the column in SADP so you/we can see the full IP address.
2. disable all 8 x NVR POE ports D1-->D8
3. enable NVR POE port "D1". Set the port to:
   • manual (not plug & play)
   • assign the next camera IP address as determined from your list of 6 above. e.g. D1 = 192.168.254.2 (?)
   • network mask --> 255.255.255.0
   • gateway --> 192.168.254.1
   • save it
   • if the camera fails to connect, it's likely a password issue that will need to sorted as JB outlined earlier, but ???.
4. repeat step 3 for ports D2, D3, D4, D5, D6

Once all 6 ports are done, re-boot the NVR, & verify that all cameras connect correctly.
