Motion-triggered barking alarm
Creates the impression of a dog and an active household at the exact moment someone approaches your entry point. The most effective single deterrent for a solo household because it works whether you are home or not.
Motion-activated exterior lights
At the front door, back door and any side passage or gate. Lights on timers are predictable; motion-activated lights are not — and unpredictability deters approach.
Strong front and back door locks
Deadbolts on both main entry doors. A security screen door on the front provides a second barrier and allows you to open the door safely to see who is there.
Don't advertise absence
Avoid posting travel plans on social media. Hold mail or ask a neighbour to collect it. A full letterbox is a visible vacancy signal.
Know your neighbours
Two or three trusted neighbours who know you live alone can be eyes on your property and a contact point if something seems wrong. Neighbourhood watch groups are worth joining.
Personal safety routine for arriving home
At night: park close to the entrance, have your keys ready before you reach the door, check that the door is locked behind you. Simple habits reduce the window of vulnerability.
