Yup; home security will deter a quick grab, but if someone wants to come in they will. The main things there is, will it be noticed in the act (like how much noise will it cause), and will there be damage. If you get robbed with no damage or evidence of a break-in, insurance won't pay out.

I mean me and my neighbours' houses have a big sliding glass door for a back door, one of the neighbours has had it yote in with a brick last year. Not even at night, it was in bright daylight. Probably had a laptop or something in view with nobody around.
