I am missing events in my timeline. Why may that be?

If at times you have the impression that the app didn’t record a motion-triggered video whereas there was motion, this may be due to the effective range of the camera or the so-called cool off period. 

1. Cool OFF period:
Please note that after each motion triggered event there is what we call a cool off period of 60-120 seconds (this varies per model). During this period motion is not recorded. After those 60-120 seconds, when there is again motion within the camera view, a new video is recorded, again with a maximum of 30 seconds per trigger event.

2.The effective range, that is the range within the camera detects and records motion varies per model:

• The effective range of the indoor cameras is around 5m/16.4ft in daytime mode and to around 3m/10ft in night vision mode. 
• The effective range of the outdoor cameras is around 10m/30ft in daytime mode and to around 3m/10ft in night vision mode.
• The Orbit has a range of 2-5 meters/6.5 - 16.4ft (depending on the angle of the object). 
• The Focus72 has a range of 10 meters/20 ft, irrespective whether is day or night (albeit that it depends on the detection method use: PIR or software).
