My DS-2CD4A26FWD function very fine, but one month ago I should change some setting under Intrusion detection and Line crossing detection. When I come to "save" I got the message "Device error" in a little box down in right corner. Basic Motion can be saved with no problem. The same with Defocus detection under "smart event".
I have tried questioning my hikvison supplyer with poor result. I have since upgraded to last firmware hoping it would help, but no.
Hope for help.
