CCTV IP POE help needed
Discussion
Hi all,
I've recently moved into a new (to me) house with IP CCTV POE cameras. The previous owner didn't have any details about the passwords for the existing NVR or cameras so I have bought a new set hoping to utilise the existing cat5 that's already been run.
I have plugged in the new NVR and replaced all the cameras but they will not link up. The network connections are not coming online and I have no link lights at the back of the NVR.
The RJ45 only has 2 twisted pairs 1,2,3 and 6.
If I connect one of the new cameras via a normal ethernet patch cable they work so I am assuming it's something to do with the cabling.
If anyone has any ideas or suggestions it would be much appreciated.
Thanks

There are 2 types of poe, one uses 123 and 6 for power and data, 1 uses 1236 for data and 4579 for power.
The old recorder will have used the former, your new recorder will be the latter.
If your cameras can use both which is normally the case you might be able to rescue the situation and reuse the existing cabling by using a poe network switch that supports 1236 power and data, plugging the cameras into that then plugging the switch into the recorder. I jave used this method with hikvision cameras and recorders, the hikvision cameras will take power either way but the recorders only use 4579 power. This allowed me to ru 2 cameras down 1 cat5 cable where the client did not want to redecorate because the cabling went in as the house was built and he wanted some more cameras.
Plug and play probably wont work you will probably have to configure your camera ip addresses manually.
Thank you so much for this info. The old recorder will have used the former, your new recorder will be the latter.

I connected a POE switch and manually configure the IP addresses of the cameras and it's all worked!
Thanks again OGH!
