Recording with slower frame rate than analysis
Posted: Thu Dec 23, 2010 7:31 pm
I would like to 'mocord' my backyard with a normal frame rate of 0.25 (one frame every 4 seconds). Then during alarm, have it go up to 20fps. I am already doing this.
However, when the normal frame rate is 0.25, the motion detection doesn't work as well, as there are bigger jumps between frames, and it can take 4 seconds before it knows there is motion.
So, is there a way for ZM to analyze a camera at ~5fps, record at 0.25fps, and alarm at 20fps?
In case this is not yet available, I think a quick way to enable this would be to provide an option of (Record 1 frame per X analyzed), with an input of X. Then have a code loop that only stores the first image of the loop of X repetitions.
