The GDS3710 is not working with GVR3550/GVR3552 recorder with GRANDSTREAM-protocol, only with ONVIF connected by hand.
This means the ‘Region Config’ for Event Setting is not working, so the motion detection is useless and you can’t record only when something moves.
So you can only record 24h or scheduled, but this doesn’t make much sense for an entry-cam.
It’s one of the main advantages of the GVR355x that you can record by motion detection!
This really has to be fixed! It should work like a GVR36xx camera in connection to the GVR355x recorder.
