What Are Pet Immune Motion Detectors and How Do They Work?

Pet immune motion detectors disregard the motion caused by animals weighing less than 80 pounds (in many instances). Most security system motion detectors use passive infrared (PIR) motion detector technology to monitor heat changes in a designated area.

With a traditional motion detector, when your pet enters the coverage area, a sensor is tripped and causes a false alarm. Pet immune motion detectors ignore the motion caused by animals and thus reduce the likelihood of a false alarm. Features vary by manufacturer and model, but can include selectable sensitivity for pets up to 40 pounds or those weighing up to 80 pounds and can be set to disregard one large pet, like a full-grown dog or several small pets, like cats.

SafeWise strongly encourages homeowners who have pets to invest in pet immune motion detectors.

Often, homeowners with pets don’t set their home’s security system fearing their pet will activate too many false alarms, which could result in hefty fines or being placed on a “do not respond” list by authorities.

However, not setting your home’s alarm weakens your family’s defense against criminals. An essential component of your home’s security system, pet immune motion detectors allow you to set your home’s alarm with confidence and give your pet the freedom and comfort to move about without setting off a false alarm.

When you take advantage of pet immune motion detectors, you’ll never again have to sacrifice the safety or your family or security of your belongings. If you’re a pet owner, SafeWise invites you to call 1-800-398-2128 and speak to a SafeWise security specialist about the benefits of using pet immune motion detectors.
