Britain is a nation of pet lovers, so it is not unusual for our skilled burglar alarm installation engineers to be asked if a dog or cat will trigger endless false alarms.
The answer is no, but with some caveats. Pet-friendly burglar alarms are very efficient these days and can usually differentiate between a family pet and an unwanted intruder.
But they cannot be 100% effective, and much will depend on the technology they use and how efficient the burglar alarm installation.
Of course, pets and intruder alarms can work together. The family dog can be just as much a deterrent as an alarm unit and pets can often alert householders to an unwanted visitor.
And as good as any alarm system is, no one can guarantee they will not experience a false alarm at some time. But modern detectors are now super-efficient and improving all the time.
Pet-friendly detectors can work in many ways and mainly depend on which type of technology is employed during installation.
Passive Infra-Red (PIV) alarms work by detecting body heat, and they can be calibrated to ignore various sizes and shapes in a room.
One problem with PIRs is that they can suffer interference from radio waves and that may cause them to behave erratically. One solution to this is an RFI stabiliser which will help overcome the problem.
Movement detectors can be positioned and set to ignore motion below a predetermined height so that cats, dogs and other pets can pass by unnoticed.
One drawback to this is that pets can behave in unpredictable ways, so it's not always possible to cover all eventualities. From active puppies and sofa leaping kittens to flying parrots, pets still have the potential to trigger alarms.
To counteract such problems, dual technology systems have two sensors, one for heat and another for movement. Again these can be calibrated to ignore pets and can also be configured to require both sensors to be triggered before the alarm is set off.
Fortunately, home security companies have invested lots of time and effort into solving these problems and designing pet-friendly alarm systems.
Scientists and engineers have recorded and analysed hundreds of hours of animal and human movements in confined spaces to determine patterns of behaviour.
Sophisticated algorithms have been devised that can 'learn' about their environment and so conclusively separate human from animal movement.
Pet-friendly sensors are becoming increasingly effective at detecting animal motion using sophisticated technologies to assess mass, speed, weight and movement patterns of moving objects and thus eliminate movement by household pets.
With surveys showing around nine million dogs in the United Kingdom and nearly eight million cats, it makes sense to install a burglar alarm system that won't go off every time the family pet jumps on the sofa.
Home alarm security installers with years of experience show that, even with the latest scientific advances, this is not an exact science.
Professionals may advise on home security systems that rely on door and window contacts to trigger burglar alarms.
No home alarm system is entirely foolproof but with professional advice on detection systems and their installation.
With a fully fitted professional pet-friendly burglar alarm system in your home, you can leave the house safely knowing that your home is fully alarmed and protected from intruders while your family pets are free to roam without triggering a false alarm.
