Many people hesitate to purchase a home alarm, worried they may have to leave their family pet outside in order to arm their alarm system. The concern was that the pet may walk in front of a motion sensor, and cause an alarm.

Most pet motions use a dual lense feature, which gives the device the ability to distinguish humans from all household pets under 2 1/2 feet and up to 85 lbs (depending on the model and sensitivity adjustments). A model with these specifications will not sound an alarm if one of your pets (small dogs, cats) walks into the coverage area. If you have more than one pet, it would be a good idea to keep each pet separated from each other while the system is armed. Two or three pets in front of the same motion sensor at the same time may confuse the sensor, and cause an alarm.

Your pet immune motion detector should be able to tell the difference between intruder threat and a family pet – consistently. It’s a good idea to have your pet walk in front of the sensor during your installation, so the installer can make any necessary adjustments.

However, while you find some deluxe products out there from brand name selling at skyhigh price claim genuine pet immune, but are you sure they alarm correctly always? are you sure they can tell me the difference between a human and a big dog or a fox or a bear or a wild pig (maybe a joke, you cannot find a fox, a bear or a wild pig to try. right!! you know the result, when they drop in your house one day – though that too late). A reality is that you know you house best, you know what kind of pet will be there, how don’t you take one to try. Any PIR motion detector has an angle of detection, test or imagine if your pet will fall into the detected area. If not, I would expect a cheap and most entry-level motion detector will give you an acceptable result – though a false alarm may not be 100% eliminated.
