RNL36 & 823A alarm logic

[user_639868941582417_639868941582417]

I have a RNL36 and and a 823A. I use the RNL alarm output,. I see two or three variations in functionality (latest firmware installed) and do not understand what is happening. Is there a certain sequence in the firmware that causes this? To me it looks like the 823 sends an alarm, and it decides to yes or no switch on the spotlight. The RNL receives the alarm, switches on the alarm output, but might not start recording. So i have condition 1, all works fine. Conditions 2 and 3 are false alarms and for some reason almost only in the early morning before sunrise hours, and in the evening after sunset And it is then sometimes almost continuously. What is causing this and how can i reduce it? Alarm delay setting has no effect, sensitivity als not. Rain doesn't seem to affect it, and any moving trees/bushes are blocked. Pet's are disabled and I use a minimum object size

1) I walk outside in the dark and it works great; 823 LED lights go on, 823 tracks me, RNL36 records, and alarm output (a light) goes on
2) Alarm output light goes on, nothing happening outside, no recording, and no 823 spotlight (happens much less with current firmware)
3) As 2) but it starts recording too
