Motion Record Settings
Motion Record Settings
Hey all. So, I have played with these settings for a while, and it seems like I always have issues with this one camera not recording when I walk anywhere in the zones. It will pick up in the closer (bottom) zones some, but almost never in the top (further away zones). Any ideas what I need to change? I have 4 other cameras with these same settings with 4-6 zones and they all seem to work fine with these settings. The blue circles are where I do get picked up on motion the most.

Re: Motion Record Settings
Big thing is change units to pixels from percent.
Don't see the res, but smaller is easier on the cpu.

I changed from percent to pixels on my previous hardware, it is much better way to get accurate settings for motion detection. For example pixel counts that remain when you change from percent to pixels, were very much bigger than after tuning motion detection with pixels.
I added new zone, changed it's size to reflect expected object sizes to get accurate pixel counts(zone size in pixels), then deleted it after done. False alarms dropped to minimum and according to tests I made, it did not seem to miss any motion I wished it to see.

Re: Motion Record Settings
Turn on analysis frames and set the sensitivity really high (low minimum alarmed pixels, filtered pixels, and blob area; no maximum). Remove preclusive zones, if you have any. You should then get recordings on even slight movements. Scroll through the stats for the alarm frames you get to see what the alarmed pixels, filtered pixels, and blob areas actually were, and use that information to tune your settings to capture just what you want without too many false events.

In master I recently changed the defaults to 0.01% for all those minimums.
Seriously instead of 3%, 0.01%.

Re: Motion Record Settings
After you change to pixels what I tend to do is temporarily create a zone about the size of the object to be detected. This will give you an approximate pixel count. This trick will get you close then it is a matter of looking at the analysis frames and adjusting.
