Pet-immune sensor

« Back to Glossary Index

A pet-immune sensor is a type of motion detector used in burglar alarm systems that is designed to ignore the movement of small animals such as cats and dogs. This is particularly useful in residential settings where homeowners have pets that may trigger false alarms. The sensor works by using advanced algorithms to distinguish between the movement patterns of humans and animals, ensuring that the alarm is only triggered when a potential intruder is detected.

In the commercial and residential burglar alarm industry, pet-immune sensors are becoming increasingly popular as more and more homeowners have pets. False alarms can be a major inconvenience for homeowners, and can also lead to fines from local authorities. By using pet-immune sensors, homeowners can have peace of mind knowing that their pets will not trigger false alarms, while still maintaining a high level of security.

1. What is a pet-immune sensor in a burglar alarm system?

A pet-immune sensor is a type of motion sensor that is designed to ignore the movement of small pets, such as cats and dogs, while still detecting the presence of an intruder. These sensors use advanced technology to distinguish between the movement of a pet and that of a human, reducing the likelihood of false alarms.

2. How does a pet-immune sensor work?

Pet-immune sensors use a combination of infrared and microwave technology to detect motion. They are programmed to ignore the movement of objects that are below a certain weight threshold, typically around 40 pounds. This allows pets to move freely around the home without triggering the alarm, while still providing reliable detection of human intruders.

3. Are pet-immune sensors effective in preventing false alarms?

Yes, pet-immune sensors are highly effective in reducing false alarms caused by pets. By ignoring the movement of pets, these sensors can significantly reduce the number of false alarms that occur in homes with pets. However, it is important to note that pet-immune sensors are not foolproof, and may still trigger false alarms in certain situations, such as if a pet jumps onto furniture or climbs onto a shelf. It is important to choose a sensor that is appropriate for the size and behavior of your pet, and to test the system regularly to ensure that it is functioning properly.
