Has anybody got a security alarm?? Not one that's wired in, the yale wireless budget type of thing? I really would love to get one for our new house but 1) do they act as a deterrent or as a 'TRY AND BREAK IN, I PROMISE IT'S WORTH YOUR WHILE' sign - because of the box on the outside (it's more for personal security than valubales) 2) do they work or do they go of all the time (we want the sensor that monitors movement type) 3) are they worth the money 4) what one would you recommend but not something super expensive, we've just had our house renovated and nearly every penny has been spent so dh would kill me if I spent a lot:) thank you for any help
