What to check before buying a motion sensor for UK doors
Consider the power type: wired sensors are more reliable but require installation, while battery sensors offer flexibility. Check the detection range and angle to ensure coverage of your door area. Pet immunity is important if you have pets to avoid false alarms. Also, verify compatibility with your existing alarm system or smart home hub.
Mistakes to avoid
A common mistake is ignoring the detection angle, which can leave blind spots near doors. Another is choosing a non-pet-immune sensor for homes with pets, leading to frequent false alerts. Also, avoid buying a battery sensor without checking battery life and replacement costs. Finally, ensure the sensor is rated for outdoor use if placed under a porch or in a drafty hallway.
