Dear all.
Me and my brother migrating from a zoneminder setup, to proper NVR board setup, with dahua 2,3 & 4 Mpiix CCTV camers.
By brother ordered this board on aliexpress
But actually received a much newer and better 24ch@1080p / (8ch@4k) noname Chinese NVR board. we have not been able to identify the board model etc.
It works well and has all the standard NVR features we need, for instance an event-server interface which is needed.
The only thing it does not seem to offer is proper pre-recording.
In my opinion, 5-10sec pre-recoarding on the event is absolutely necessary, because any event / person detected will be ½ way through the frame when the video starts, if the pre-recoarding is not enabled. The first part of the frame, the person has not seen the cctv and are not aware of the recording, and typically looks around etc. This first important half of the event is missing without pre-recording!
Can anyone suggest a better or different NVR board that offers the same standard features together with event-server and proper pre-recording, in the aprox. same price range and Channel size
My dahua cameras supports the pre-recording on the camera firmware, but unless its supported on the NVR side, it does not work.
I hope you can help ;O)
