Cabinet Alarm

[Guest adrianf]

I'm trying to source some type of device to protect some antique display cabinets which contain more antiques. I'm after a battery powered device that sounds when the doors are opened. The units or sensors need to be small as the look of the cabinet can't be comprimised. Any help or info would be greatly appreciated.

Thanks in advance.

HERE is the cheap and cheerful option! I have nothing to do with the auction by the way.
