JJ, Helpful... thanks.
I parked my car in the street of a small town near to where I live. The car was nose to the kerb and the sidewalk/pavement quite busy. Returning 2 hours later there were 158 incidents to review. It seems that it recorded everyone walking passed triggers the sentry. Far too much data to be of any use, is there any way the system could be desensitized, so it is only triggered if someone touches the car or stands by it for more than 10 to 15 seconds?
