Device error when trying to change Intrusion Detection on Hikvision DS-2CD4A26FWD-IZHS

[llars]

Everything else seems to work fine including Intrusion Detection, Motion (expert) and Line crossing, but when I try to change Intrusion detection or Line Crossing I always get "Device Error". As I am 200 miles away from the camera I am a little afraid to reboot. Is there something else I can do?

I would like to move the detection area to suit better as I would like to drop Motion which react on almost every change in light, shadow and insect.

I travelled to the camera, but I still have the problem spite I have upgraded firmware to latest version with automatic reboot. Everything else function all right, but not the above mention problem which still occors when I try to save changing in Intrusion Detection og Line crossing detection.

Any suggestions? Hikvision didn't answer either direct or via supplyer (shop in England).

The camera model is DS-2CD4A26FWD-IZHS (darkfighter).
