HIK IP PoE Camera IP Address "Reset"

[Yama1300]

Hi "lewic", thanks for the detailed and informative reply. I changed over the cable as you suggested and I instantly got one camera back- the one that I lost when I
was playing around with cabling a couple of days ago. So that's two out of four !! I connected the NVR to my PC and pulled up the SADP- I see two camera's listed
with 192.168.254.x IP's, plus the NVR this is listed twice with different IP's ! I thought I would see the other two camera's on the SADP as well having changed over
the cable -I just tried to add manually on the NVR but still getting "network unreachable".
I'm misunderstanding something here.

See images

Thanks for your patience
Cheers

JG,
Let me get an idea of how you have everything. The screenshot of the SADP. Where is the computer plugged in? Where are the cameras plugged in? Are the cameras plugged into the switch or the NVR’s onboard POE?

Let me infer. Your cameras are currently plugged into the switch on the router side. If so then that is why you cannot see the cameras. SADP will only show the Hikvision devices that are on the current network. This makes me feel that your computer is plugged into the router side. If this is the case then you will only see the NVR and also the cameras that are plugged in on the router side. Meaning you will not see the cameras that are on the NVR’s POE since those are technically on a different network. If this is true then look at the two cameras on SADP. You have these two cameras on the switch and not on the NVR’s POE right? If that is true then the problem is the IP address of those cameras. The reasoning is like so.... The NVR’s POE is on the 192.168.254.1 network so each camera’s connected to the POE’s will have a 192.168.254.X number. This number is assigned to the cameras and if you then disconnect the cameras from the POE and connect it to the Netgear switch which is not connected to the POE but on the router/LAN side, the cameras are still listed as having a 192.168.254.X number but are currently on the 192.168.1.X network. Look at your NVR’s IP address for the cameras. It is showing 192.168.254.X. Yes the IP address is matching your camera’s IP address but the issue is where you plugged in the cameras. When you put in 192.168.254.X in the NVR for the cameras then the NVR will think to look at the onboard POE because “X.X.254.X” is for the POE. It will not look for the cameras on the Netgear switch because as you said before those devices are listed at 192.168.1.X network. You have two options to fix your issue.

Option 1.
Unplug the cameras from the Netgear switch because you currently have two 192.168.254.X devices on the 192.168.1.X network.
Plug those cameras onto the NVR’s POE ports. This would put the 192.168.254.X (cameras) back on the “254” network.
Your cameras should work immediately after booting up. (It takes roughly 20 seconds or so for the cameras to be online because once you plug in the cameras to power they go through a boot up process before they will appear.)

Option 2.
You keep the cameras on the Netgear switch. In order for your cameras to work you need to change the IP address of the cameras.
Netgear switch is a 192.168.1.X network so you need to give the cameras IP addresses on that network.
Easiest way would be to select the camera by putting the check mark and on the right hand side you will see the settings for the camera. Check the box that says “Enable DHCP” and enter the camera’s password at the bottom and click modify. Click refresh a few times and you will see that it has changed the IP address of that camera.
Do the same thing for the other camera.

Once you have those updated IP address and those cameras are giving you a 192.168.1.X number for each.... You will be going back to the NVR and changing the IP address for those cameras. So on the camera screen you will click the edit icon (pencil) listed for that row for the camera. It will open up a new window with the camera’s information.
Double check this:
Camera is set to manual and not plug and play (plug and play only works if you are plugged into NVR’s POE)
IP address - this is the 192.168.1.X number
User name and Password - default username for the camera is “admin”. Enter the password....
Then click apply.
It should take a few seconds and show connected after that.

Let me know if this helps.

Hi Lewic I have both Router and PC problems today- just started to reinstall Win 10 as it became really unstable, internet seems ok again. Just scratched out a diagram of cam setup,see image, sending this from my phone, THANKS again much appreciated Cheers John

John. So the Netgear is plugged into the POE port of the NVR and not the LAN port. What I would do is plug the computer into the netgear and run SADP. You should see all the cameras along with the NVR. If cameras not showing up then check the power. In your scenario then yes each camera will keep the 192.168.254.X IP address. Make sure the ethernet cable connecting the camera to the switch is good and not over 328 ft (100 meters). There is not any reason for the camera to not connect if:
1. Cameras all have a different IP address.
2. Cameras are added using manual instead of plug and play.

The netgear switch you have is POE right or just a regular switch?

Hi "lewic" Thank you again for the very quick response, our Network is just about working, every device is crawling along, still waiting for Win 10 to complete on PC and trying to use it or anything else is a royal pain. The Netgear Switch is an unmanaged 4 port POE (GS305P). The cable length is approx 35ft. Once the ISP sorts out the bandwidth I'll go with your excellent suggestions. It's after 9pm here now so it's going to be Monday before I can start working on the camera's again. Bars and Cafes are closing here at midnight,all schools and colleges closed and lots of companies because of the C19 virus. Hope you are safe, Cheers John
