We regularly get asked about our pet friendly alarms because, according to the PFMA (the Pet Food Manufacturers’ Association), in 2015, 46% of UK households owned some form of animal.
That’s around 58 million pets living in the homes and gardens of British residents. And, as a security system installer, in many cases, it’s also another family member that we have to think about when we survey a home.
Most house alarms use PIRs (Passive Infrared) sensors which detect movement using infrared light and many struggle to tell the difference between a human and a dog.
As a result, some homeowners think that having a pet means you cannot have an intruder alarm, but some modern alarm sensors are able to differentiate between an unwanted intruder and your favourite two- or four-legged friend.
So, if you want your dog, cat or budgie to be free to roam/fly around the house whilst you are out, you need a motion sensor with more than one field of view. These could be at a human’s chest and knee height with both needing to be triggered simultaneously to activate the alarm system.
For most animals this is sufficient as they will not be big enough to trigger both sensors at the same time. However, if you do have a particularly large dog, you might need to talk to us about options that are based on the weight of the animal, its body temperature and movement patterns.
Alternatively, you could look at the placement of your motion sensors.
