There are already commercial garden beams (real beams) and you get outdoor IR sensors and such too, dont need to invent you own, and they can intergrate with your alarm system or just have their own siren.
Anyway, security is best layered.
Perimeter: Wall or fence. Then something on top, razor wire perhaps, that thing cbrunsdonza posted also good, electric fence best though, offers physical deterent and perimeter alarm (it need to be on and also linked to a siren or alarm)
Garden: Beams, IR sensors or similar, dogs, motion activated lights or normal lights. You can have a mix of these as you want.
Home: proper burglar proofing, alarm with infrared and door magnet sensors. Remember smoke alarm or 2 (around R150).
