Note that there are security cameras in certain areas.
Despite burglar alarms and even guard dogs break-ins have been known to occur. Well, not with the dogs around, it's true.
If premises are unoccupied and an alarm is sounding, do not enter alone. Call the police and report. Ask for help. Do not touch anything.
If you are attacked by thieves, don't be brave. Give them anything they want, including cash. Try to remember as much detail as possible about the attacker(s) to help the police with their enquiries later.
Do not take risks.
