That's quite simple... You do what brings success. Assuming that with RC2N you will be safe forever is just naive. Once most houses are equipped with RC2N, the burglars will just take a glass hole cutter instead of a crowbar and almost silently drill holes in the glass. No need to smash it. When everyone has RC2, then they'll move on to torches and circular cutters. And so on. You can only create as much distance as possible between your own and the usual equipment to become as unattractive as possible to the average burglar. Security was, is, and will always be an arms race; whoever stays ahead, wins.
And what is the video system supposed to achieve then? You'll have a nice image of the perpetrator, and then? For a manhunt, such images are completely useless, and the lost sense of security doesn't come back either.
Just as a side note: Here (25km from the nearest big city) in recent months several windows were simply smashed, and then the (lockable!) bolt was opened from inside using a pipe extension. With RC2 this wouldn't have been that easy because of the laminated glass. The criminal investigation department was "appalled that no one heard the glass breaking"... but that doesn't surprise me nowadays at all. It is heard for sure, but nothing is done.
