What kind of detection do you use?

[Jannick]

Before i upgraded my nvr i used IVS on all my cams, but that feature dissapeared when i upgraded, unfortunately.

So now i just use motion detection but got so many false alarms, pretty anoying.

Is there a better way which is more reliable?

Anyway to downgrade to an earlier FW ? External sensors wired to the cameras are the best but i dont know if that works for an NVR. Like PIRs, magnet sensors, pressure plates and so on.

I thaught i could, but Really cant find any earlier FW that Will install, tried many different but all makes error. It’s a Dahua nvr4204

Well never thougt of that, but dont know eather if it’s possible.

Thanks for reply.
