Hello everyone, I am experiencing a strange problem between TVT IP cameras and Dahua POE NVRs.
The same thing happens to me with different models of cameras and different models of POE NVRs of that brands.
The cameras are 4MP.
The cameras, to be managed by the Dahua NVR, have to be activated, given a certain IP address and must have Onvif enabled.
I explain what is happening:
Case 1 - the camera has address 192.168.1.200 and is connected to an external POE switch in the NVR's LAN = perfect
Case 2 - the camera has address 10.1.1.2 and is connected to the POE port 1 of the NVR = occasionally freezes and there are holes in the recordings
Case 3 - the camera has address 10.1.1.2 and is connected to the POE port 1 of the NVR but is powered by 12Vdc (I thought: "maybe it's a power problem") = occasionally freezes and there are holes in the recordings
Case 4 - the camera has address 10.1.1.2 and is connected to a POE switch from which, from the UPLINK port, a cable goes to the POE 1 port of the NVR = perfect
The case seems very strange to me.
It seems to be a problem of incompatibility between the 2 products in the use via POE port of the NVR.
It's not an ONVIF problem because it works fine in certain modes.
It's not a power supply problem because at 12Vdc it doesn't work well.
It is not a POE port bandwidth problem of the NVR because if I connect a POE switch at the POE port 1 of the NVR, the camera connected to the switch works fine.
I don't understand what's going on and wonder if it has happened to any of you before.
Thanks in advance.
