Sorry to hear about the breakin, bastards....
Anyway, the National Parks and Wildlife in NSW are using small portable CCTV's, quite inexpensive and are getting results.
Our department at work is seriously looking into buying some and putting them in places to catch rubbish dumpers, vandals and general idiots in our parks.
www.farmcam.com.au/I've bought two, stuck one in the front garden facing towards the front door/windows etc and the same out the back. They work well, bloody Bandicoots digging up the lawn, we got visited by a couple of cats and the resident python.
The camera works at night via infra red and can be time lapsed and such....they're not bad.
Note: I have no affiliation what so ever to the manufacturer.
