Pet-Friendly Alarms UK Guide
UK homes with pets face a unique challenge when choosing a burglar alarm. Standard motion sensors cannot distinguish between a burglar and your cat or dog, leading to frequent false alarms. Pet-friendly alarm systems solve this problem with specialised sensors that ignore animals while detecting human intruders.
How Pet-Immune Sensors Work
Pet-immune PIR sensors use advanced signal processing to distinguish between humans and animals based on body mass, heat signature, and movement patterns. A sensor rated for pets up to 25kg will ignore animals below that weight threshold while still detecting human intruders.
Some sensors use dual-element or quad-element detectors that compare signals from multiple detection cells. This allows the sensor to reject the smaller, faster signals produced by pets while triggering on the larger, slower signals from humans.
Choosing the Right Pet-Immune Sensor
When selecting pet-friendly sensors, check the weight rating carefully. Standard pet-immune sensors are typically rated for animals up to 15kg, while premium models handle up to 45kg. For homes with large dogs, choose sensors with a higher weight rating.
Consider the mounting height and location. Pet-immune sensors work best when mounted at 1.8-2.4 metres high, angled slightly downward. This creates a detection zone above the pets normal movement area while still covering human-sized targets.

Installation Tips for Homes with Pets
Position sensors so your pets cannot climb or jump directly in front of them. Avoid pointing sensors at stairs or furniture that pets use to climb. Create pet-free zones in areas with motion sensors, or use door contacts instead of motion sensors in pet-accessible areas.
Consider using door and window contacts on ground-floor entry points instead of motion sensors in rooms where pets roam freely. This allows you to have the alarm set at night or when out while your pets move around normally.
Key Takeaways
- Pet-immune sensors use advanced signal processing
- Choose sensors rated for your pets weight plus margin
