I have domestic CCTV system with 7 Vivotek cameras and a Vivotek ND9322NP-V2 NVR. The NVR is in kocated in the garage togerher with the network cabinet. I'm really pleased with it however a little concerned that whenever we get a warmish day ( say 75 deg F) the cooling fan in the NVR seems to run continuously.
Should I be concerned? Would it cool better if i mounted it vertically?
