False motion trigger during day/night transitions

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