Searching for a smart motion detector

[rrzepka]

The motion detection solution that I am searching for is ideally:

* analog in design
* capable of sending a configurable message (e.g. Room 3, zone 1) in a software readable format (e.g. XML)
* selectable or tunable motion sensitivity

The problem I am attempting to solve is how to turn on multiple analog dome cameras in a multi-room scenario as long as any one of the rooms is occupied. I have the software solution to capture, encode, and store video/audio in MPEG-4 format using the keyboard. However, I am missing a motion detection capability with the aforementioned characteristics.

Does anyone know of such a smart motion detection device?
