Motion detection: Sensitivity & Tolerance query
Posted: Wed Oct 03, 2012 3:55 pm
I'm having a bit of trouble setting up the motion detection settings.
My camera points at the sky and records the stars at night, this is done by 30s snapshots combined into a .mov file later on.
Obviously sometimes meteors etc appear in the sky and I wish the motion detection to pick these up.
So far my results have either been the motion detection does not trigger or i end up with 150k images per night as it detects everything.
The auto detect usually puts the settings at:
Sensitivity 75-85% and the Tolerance pretty much stays at 20%.
I;ve played around with these settings manually but i just cant find the right settings.
Has anyone done a similar set-up, looking for motion on a pretty much motionless dark frame, where the thing you want to capture is a bright light source? The main issue is clouds moving across as they are a large change in motion as opposed to a smaller moving streak of light.
