HIKVision 7608 installation driving me nuts

[genwolf]

I am trying to set up a HIKVision 7608 that is driving me crazy.
The situation is that the bussiness had an existing security camera setup consisting of 8 cameras that came back to an NVR which was seized by the police after one of the partners was accused of smuggling tobacco products. The owners don't remember what the original NVR was but from their description of the interface it was probably a HIKVision. All the cameras are still in place and their cables terminate at one point. There was existing cabling from the modem router to the old NVR.
So far I have succesfully connected the NVR to the network and it is visible to SADP and you can login to its web interface.
The router Subnet is in the 192.168.1.x form and the NVR is using DHCP
After connecting all the camera cables to the POE ports on the NVR all the rx and tx lights are blinking green.
But neither on the router nor on the monitor interface, nor with SADP tool, are the cameras visible. I have tried a number of protocols, but all the camera ports just show network unreachable messages.
According to this thread (Hikvision NVR POE not detecting my cameras)apparenty some people have had succcess running a 2nd ethernet cable back to the router from one the POE ports on the NVR. I have ordered a 30m cable to try this. The HIKVision manual is pretty useless for any purpose other than getting a fire started. I have attached pics of setup.
Any advice would be greatly appreciated.

The NVR acts as a firewall of sorts so you will not see cameras connected to the NVR POE ports in your router with any other device as the cameras are now on a different subnet.

Your mistake was connecting all the cameras at once.

You can try unplugging them and then plug one in and wait and see if the NVR sees it. If not (and probably not as either the previous NVR or owner assigned it passwords), then factory reset the camera and wait for the NVR to see it and then plug in the next camera.

Thanks for your response, before connecting any cameras should I try and delete any settings I made in the NVR camera management page or should I maybe start by resetting the NVR as well?
Is the only way of resetting the cameras usually finding a physical reset switch? The way these cameras are installed this is a major job, they are mounted high up in hard to reach parts of a warehouse.

Yeah I would go ahead a try resetting the NVR as well.

Yes you can reset the cameras without using the physical reset, the problem is that you need to be able to log in to them - if you could log in to them, you wouldn't have this issue!

Do you know the user/password of the old NVR? If so, make that the user/password for this NVR. And hopefully they didn't make the cameras different and by plugging them in one at a time it will find them and add them.

They could have setup Static IP's, oh i see they show IP's...
Ok then the USER/pass of the NVR is often handed off to the Camera and will only respond to the Previous USER/pass.
which would require a physical hard reset of the cameras.

I will give this a try and let you know how it worked
