Outdoor motion sensors

[eNRGy]

Hi all, is there such a thing as an outdoor motion sensor that does not use batteries (eg mains powered) for use on 220v or 12v?

That will work with Telldus gear.

Reason being my outdoor sensor keeps dieing and I think the batteries don't like the cold in the winter.

I haven't seen any detectors that are mains powered.
It shouldn't be too hard to add some voltage regulator and feed the detector from an external power supply.
