I'm wondering if this is possible ...
Have existing LPR camera at a parkade gate to view entry and exit - it is the only way in or out. Is there a way, using either VMS or the access system (in this particular case Lenel), to use the plate DB to create an alarm if, for instance, a plate goes in, but does not exit for a prescribed period of time? Essentially object left behind, but the object is a car, and we know it is left behind because the LPR camera saw it go in at 1 pm but 8 hours later it had not exited. Thanks.
