The sensors that detect movement on your home's alarm system are there to make you feel safe and to protect your property. They give you a great sense of security. However, they can also give you a few headaches if you have pets. For example, cats and dogs can both trigger motion sensors setting off false alarms on a regular basis. This can be irritating enough for you but spare a thought for your poor neighbours who may end up cross as a frog in a sock if they must listen to regular false alarms when you're not at home and your pet has danced the fandango in front of a sensor.
