Thanks for answering. I commented that the cameras if wireless IP connected wirelessly to the Router, the router is connected to a cable modem and I connected from one of the router ports to the DVR. With the PC I connect via Wi-Fi directly to the router and type in the browser of some of the IPs of the cameras I enter without problems and I have an image now my problem is that I bought this Tribrido DVR that supposedly connects to the network and detects the connected cameras and no one recognizes me, I want to use it to store the images. I don't know if I explain myself.
Yes, they are in the same range, the router's IP is 192.12.12.254
The ip of the cameras is:
Cam1 192.12.12.100
Cam2 192.12.12.101
Cam3 192.12.12.102
Cam4 192.12.12.104
They are ONVIF and are connected by wifi (wireless)
And the DVR 192.12.12.105
The DVR is connected to the router via cable and in turn the Router is connected by cable to the Cisco brand Fibertel cable modem.
And they are generic Chinese equipment.
