Here is how. If someone forced a window tonight, who would hear it? Read on: it takes a few minutes and could save you a lot more than that. **In this guide you will see:** - Pet-immune sensors ignore small animals when mounted correctly. - Sunlight, heat and moving curtains cause false alarms. - Mount at the recommended height and angle. Quick answer Most false alarms come from sensor placement and pets. Pet-immune PIR motion sensors ignore animals under a certain weight (often around 20 to 25 kg) when mounted at the right height. Avoid pointing sensors at windows, heaters, curtains or fans, keep them away from direct sunlight, and use door contacts and sensors in places pets cannot reach. Good installation prevents most false alarms.

They are rated for animals up to a stated weight; a large dog may still trigger them, so use door contacts or keep the dog out of the covered area. Why does my alarm go off at night? Often a sensor in the sun, a fan or curtain, or a low battery; we inspect and fix. Can I bypass a sensor temporarily? Yes; panels let you bypass a zone, but fix the cause. Should I use stay mode? Yes; stay mode leaves the downstairs sensors on while upstairs sensors are off. ## Why customers choose Qyvea **Genuine brands**: Manufacturer warranty on what we sell, so you are not gambling on the box. **One team, start to finish**: The people who advise you also install and support it. **Fast answers**: WhatsApp replies usually within 30 minutes, and delivery within 24 hours in Nairobi. **Easy to buy**: Pay by M-Pesa, bank transfer or card.
