I am using Hikvision NVR, the strange thing is that it requires configuring/enabling motion detection in both camera and NVR together in order to function. Despite that the actual settings it uses from the camera.
yup hik nvr like a NAS, and the cam just only send trigger when nvr must record, but you dont have set twice if you set on nvr it will update setting on camera also, but not opposite
so since new hik firmware nvr not send me email with picture i'm disable email from nvr, but enable push email in camera
