We've had these things for a while now. Plus a night watchman who inhabits the starting tower from 7 to 7, security gate, movement sensitive lights etc.
There seems to be always somebody or something looking ,checking. It's good to have in a way, but I find I'm a little uncomfortable with the thought of this all pervasive intrusion. What next, a remote boat security set-up in contact with a shore based security centre when you are on the hook in the middle of nowhere.( please don't tell me it already exists)
