I believe strongly that video surveillance linked to security systems is the key to eliminating false alarms to police. A lot of waste is going on with traditional alarms - some police departments actively measure it and the results range from 95~99%. If you can eliminate false alarms to police, they will respond faster to your clients sites. If they respond fast and if they are silent alarms you will get apprehensions. There is not much published data on this subject.
I just completed analysis of events at our video verified outdoor sites for the months of Sept and Oct and wonder what readers opinion of my data might be. 1/4 of the sites were Car Dealerships, 1/4 were construction sites, 1/2 were out door storage areas. The car dealerships were open lots, otherwise were fenced properties. 3/4 of sites were triggered by video analytics, 1/4 were videofied cameras.
