Based on pre-record rule of Multicam, when motion happens there will always be 2 clips
recorded. One clip is Pre-rec and the other would be (motion + Post-rec). Therefore in this
case, customer's video clips per motion event should be a 2 min Pre-rec clip and another clip
with duration of the motion + Post rec.
The reason why customer's second clip has (Pre-rec + motion + Post-rec) is because
Multicam is constantly doing Pre-recording from the moment it starts monitoring. So let's say
Multicam starts monitoring at 1PM it will keep generating a Pre-rec clip every 2 mins. If a
motion starts at 1:02:30PM, Multicam will save the 2min clip of Pre-rec it has archived (1PM ~
1:02PM) and then the second clip will start recording from 1:02:01PM to end of motion + Post
rec time. This is because Multicam cannot throw away the part of the clip before motion
happens, other wise the two clips will always have a gap between them. Please refer to the
diagram below for more details.
