How to choose the best shed security alarms and systems to keep the contents safe
Briefly

Garden sheds are frequently targeted by thieves, highlighting the importance of effective security systems. A 2025 Aviva survey states that 29% of people reported a break-in or attempted break-in to their garden outbuildings, with 40% specifically targeting sheds. Shed alarms, which include various sensor types such as door/window sensors and motion detectors, can provide vital security. Door/window sensors often utilize two-part magnetic contacts that trigger an alarm when separated, making them effective in preventing unauthorized access.

Shed alarms use sensors to detect intrusion: those for the door/window; vibration sensors; and motion-detecting or PIR (passive infrared) sensors.
Door/window sensors are typically two-part magnetic contact sensors. If the door or window is opened, the two parts are separated, setting off the alarm.
