I recently bought this recorder, but I didn't notice that there is the same model with 4 POE ports, but one of them has 4 extra channels.
If everything is the same, it must be just a question of software.
If I can't, I'll even have to buy the 4108
Today I downgraded to V3.2 firmware.
Because V4.0 firmware it can't support Dahua Chinese camera.
In order to use a cheaper and latest camera, I had to do this.
