Multiple TRIG records in log for single trigger

ArduCopter Copter 3.5

Hi everybody
We have some issue with logs of camera triggers. We try to geotag photos using TRIG records. In some missions we have multiple TRIG records for what is in our opinion single event. Here is example log done on the ground, where we carried copter with distance trigger enabled:

Please look at TRIG records from 16:47:04 to 16:47:05 - there are 10 record couple hundreds ms apart. We have:
CAM_DURATION,7
CAM_MIN_INTERVAL,1400
Camera triggered once.

Do you have any hints?

Check what your camera outputs using a oscilloscope, could be switch bounce, or that camera output more than a simple signal.

OK. I may investigate it with scope, but I was thinking that TRIG records are independent from camera. I know about CAM records, which records feedback from camera, but issue here is with TRIG records.
If TRIG records are bugged we may try to modify our camera to use CAM records.
