False motion trigger during day/night transitions

[t_andersen]

I have a BI setup with three outdoor cameras that switch to IR in the evening and back to visible in the morning. Trouble is that the transition during switch-over between day and night triggers the alerts for two of the cameras (but strange enough not for the third camera), so I get false alerts every morning and evening. Has anybody figured out how to circumvent this problem i BI?

See this thread...you can clone the cameras and set a different threshold for alerts vs recording... http://www.ipcamtalk.com/showthread.php?1094-BI-Motion-detection-Outdoor-sunny-cloudy-days&highlight=clone
Another option is to create a profile around sunrise and sunset to increase the make time a bit...

I use the object detect/reject option on all my motion detect cameras and they rarely record the IR filter transition anymore.
