This is what I do to stop my bike getting nicked firstly insurance, Ive used it for the cage and bike at least five times in ten years, its saved me about 30000 dollars. get it. when out alarmed and chained to a pole where possible, my licence number is engraved on the underside of the pipes and randomly in three other places. The police station is a great place to park. when in I fixed four eye bolts to the garage floor 4 inches into the concrete, a chain the size of god is padlocked to these at both ends - this cost 40 bucks at bunnings including the drill bit. Both wheels are chained to the ground. I have anti cut padlocks at both ends with the chains padlocking in the middle so I only have to unlock two locks rather than drag the mother through the wheels. The chain has flexible plastic piping on it so as not to massacre the finish. It cost me 25 bucks to get an extra sensor for my house alarm which monitors the garage as a whole. total cost maybe 80 bucks and twenty minutes work I thought about cameras but dont believe that the cops will actually bother doing anything with footage- there is cheap bird watching cameras which are motion activated on ebay - no film just high quality fixed shots of a set point. Before I got serious about it I got robbed 9 times in three states and was starting to get paranoid. At one point I made a complicated booby trap, involving beer bottles and lumps of metal and got home to find blood all over my driveway. Oops. Damm. Ive also got a boxer called Biggles who tends to eat burglars and wag for kids. I actually really enjoy the security of having security.
