Burglars and criminals generally make the decision to enter a premises based on likelihood of available cash or goods, whether anyone is there and if you have security such as an alarm and cctv. Have an alarm, make sure it looks to be maintained and working, have cctv if you can, have insurance and lock equipment away in steel cabinets etc. Some premises are still burgled with alarms, but in general burglars feel time limited and steel cabinets can take too long to open if an alarm is already activated. Backup off site. Generalised advice, but many criminals choose easier targets if they can, determined criminals are rarely stopped. Cars can be difficult to protect once it's know gear is in there, but most are broken into because valuable items or the likelihood of them is already visible.
