Motion sensor alarms serve as the backbone of many security systems, providing the first line of prevention against break-ins by detecting when intruders are in or around your home or office. Many motion sensors have options to send alerts, turn on detector lights or trigger integrated security cameras to record the event. Some of the more sophisticated units can perform all three actions at once. Motion-sensing lights can also be ideal for providing illumination where you need it for safety. For instance, you can place a motion-detecting light where it will automatically come on each night when you take out the trash.
You can use motion-sensing devices to alert you when your children or pets enter a restricted area like a basement under construction, or your tool room. Additionally, since many of the available motion sensors can be programmed to turn on automatically at dusk and then off at dawn, it is possible to give your house the appearance of being actively inhabited while your family is on vacation.
