Many horror movies create suspense by having the main character blissfully unaware that there is a monster, serial killer or thief in their home. If only these characters had installed a motion detector, they would have known someone (or something) was lurking in their home.
Motion detectors can serve many purposes in protecting your home. Many homes have outdoor lights with sensors that will only come on when someone is walking near them. These lights also deter burglars who lurk near homes at night searching for a way to get in and steal, and even worse yet, terrorize the home's occupants. It is proven fact that burglars will run away when seen under the lights.
Home Security Essentials
Many earlier models of outdoor motion detectors were actually costing homeowners money when they were triggered by sunlight. Police and fire personnel in most cities will fine homeowners for false alarms after a certain number of them. Newer models have been developed that are not sensitive to the sun and cut down on the number of false alarms. They can also be equipped with recorded messages. These messages can be pre-recorded and are played through the detector to warn the burglar not to come any closer because the police will be called.
Many motion detectors will be linked to a camera, which will begin recording whenever someone has been detected. Hopefully, the intruder will run away and by capturing his image on the motion detector, police can catch him or her before they are able to burglarize a home or worse yet, attack a family.
Infrared technology has improved motion detectors and increased safety in businesses and homes. These will sense any movement inside or outside the home. For example, if someone manages to disable your burglar alarm and is able to get inside your home the motion sensor will go off, alerting you that someone is there. The sensor will also alert the alarm company and the police will be sent to your home.
While infrared motion detectors have deterred thieves from many homes, it has also spurred complaints from homeowners who have pets. Many families have been awakened in the night when a dog or cat has managed to get inside or escape from a safe room and is detected by the sensors. This problem has been somewhat solved by new ones that have are immune to small pets. They are often part of an overall home security package. This makes them more affordable for homeowners looking for a way to ensure the safety of their family.
