Saw an awesome product the other day, it's a door bell that rings through to your smartphone when it's pressed, with a video feed if you want. You can answer the doorbell from anywhere in the world, that's pretty smart and quite a deterrent if they check the property by pushing the intercom.
But ja all this extreme security does nothing to actually stop crooks, car security is so jacked up now that instead of stealing the car when it's parked and you aren't there they have have to hijack it with you inside, same with properties, super secure but now the occupants are at extreme risk every time they are entering and exiting the property. Counter intuitive perhaps but it seems the more security you have to protect your belongings the more you imperil your life.
