The post record problem has only existed since upgrading / downgrading V4 firmware, it worked ok with the previous V3 configuration.
Its very irritating as when a line crossing activation is sensed I get an instant push notification of the event but when I go to view the footage its blank.
Also when I clean the lens on the driveway camera it doesn't show me cleaning the lens, only me walking away from it, which is totally unacceptable (no post record)
I only have x2 cameras set to line crossing out of a total of x8 cameras..
Im running Firmware V4.1.64 build 190119 and my known problems are:
1.. Post/Pre record not working (Have now set to 5s and still not working)
2.. Line crossing showing no footage recorded (linkage method "Notify surveillance centre" + "trigger recording channel D*)
3.. Older 3MP DS-2CD2232-I5 camera no longer displays "Sub stream" and returns error (works ok on web browser)
4.. Email Notification still locks up NVR when you try and enter any details, hence why I use push notifications which work very well.
I've factory reset NVR several times with no difference.
