Feature Request: Higher level of motion detection to avoid false motion detection


I have problems with changing light conditions that I haven't been able to solve using the current setting options including use of masks and experimenting with lightswitch. Either too sensitive or too unsensitive. I've solved this using external scripts but a new feature could solve this for many users. This is what I did after completed decent settings with occasional but annoying false motion detections:

Each time a new image is saved from a detected motion, I only regard this as a higher level motion if at least 10 (or whatever) such images have been produced during the last minute, including all cams in the building. Using a value of 10 or higher, it is very unlikely to get false motions and an intruder will in short time trigger 20 or more such images during 1 minute from only one camera, much more likely when using more cameras. After 5 minutes I reset the trigger, thus only triggering this at most one time each 5 minutes. I send a push notification and an SMS each time.

The values 10, 1 minute and 5 minutes should be configurable, also set per camera or on top level. When this is trigged using a dedicated event, an external program can be called.

This really works well, I'm able to filter out all nuisance warnings while stile keeping the sensitivity of the individual detection for each camera. I also send the number of saved images during the last minute in my push and SMS message so I can also use this number to judge if this is a false alert. Current logic is that I first send a high level alert and during the 5 minutes of activation I also send messages of the individual detections at each on_movie_start, including the total number of saved images during the 5 minutes. It's then very easy to see if this is a false alert and if not, I can continuously follow what's going on for the different cameras.
