Not sure if this is the proper category - please move if necessary. 'Hypothetical' Home security cameras send alert to cell phones that 'upstanding citizen' is entering vehicle in driveway.

Use siren on security camera for same purpose? Grab weapon and confront? Tactical (sneaky) or with some kind of warning? Shelter, Call LE, and wait? Other?
