Zone Setup

I have been using ZM for some time now and am now trying to better understand how zone setup works. I have a camera pointed at our travel trailer outside and am getting more events than I care to go thru. Below are the settings for my zone, is there anything I can do to reduce the amount of false recordings?

Things that seem to cause false recording are leaves blowing through the zones, rain and lighting changes.

Thanks
Rick

alarmed pixel is a light but non filtered method, its bedt to use blobs so id experiment with that

I would agree. Adding in filtering and/or blobs will very much help to reduce clutter caused by leaves and rain. The light changes are a bit harder to diagnose without a couple of examples perhaps?

Thanks for the suggestions, however I am still not quite sure about the method of using blobs. Below is the zone setup, could you give me some pointers on where to start?

Thanks

you have used almed pixels in your previous post, chnag ethis to blobs and adjust sensitivity. Would also recommend using 1.22.2 as you can shape the zone how you like

Ok I am beginning to make some progress however I need some help on this zone. This is the bigger zone in the middle from above.

The first frame to indicate an alarm is well into the zone. I would think that it would alarm as soon as I walk into the zone.

There are several frames prior to this one that should be in alarm state but are not. Most likely the settings for the zone are not correct.

Okay now on your above alarmed picture is some what useful but what would be more useful is in that sceen top left side you see "Stats" that screen would be useful to you and us.

That frame did not have ant stats associated with it, however the next frame did.

Zone Middle
Alarm Px 815 (4%)
Filter Px 746 (4%)
Blob Px 559 (3%)
Blobs 1
Blob Sizes 559-559 (3%-3%)
Alarm Limits 145,87-167,127
Score 3

Okay now look at your min sets for your zones and the detected values for that frame.
Looks like you might need to bring your min settings down. Can you guess which one?

I would guess that the min blob size would need to be reduced a bit. However I tried that and detection appeared to take place later. I will do more testing and see.

Also as james mentioned upgrading to 1.22, I am using the LiveCD version. How would I perform and upgrade to the latest version?

Thanks
Rick
