Think about it. Are you more likely to do a nasty deed if someone can see you or if they can’t? I’ll answer that one for you. Nobody wants to be caught being naughty. That even applies to burglars.
Sensor lights are not expensive. These days, they can be mounted easily and run on batteries. Put them outside in all the nooks and crannies. Buy the kind that light up any time there is motion. You don’t even have to hardwire them. Low maintenance, easy to install.
No burglar wants to risk getting caught. The second that light shines, a thief, like a rat, will go scurrying. Put these up at the front and the back of your property.
An alternative is a timer light. These give the illusion that someone is inside the premises and can be set to come on and off at different times every night. A few of each kind, strategically placed, will provide an effective deterrent against night-time prowlers.
