About eight months ago I installed a Hikvision I-series NVR with eight 2355/2385 cams. I've always had three cams that set alarms on either intrusion or line crossing at both dawn and dusk each day. Those three cams are oriented the same direction, west, which is different than the remaining 5 cams. I've done all the tweaking I can think of to eliminate the false alerts to no avail. The false alerts have followed the changing times of dawn and dusk throughout the year. Reviewing recordings...
Intrusion/line crossing at dawn and dusk? Possible answer...
