Motion sensors and detectors.

Find the best motion detector for your needs.

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.

Types of motion-sensing alarms.

Motion detection can be either active or passive, using one or multiple technologies to discern movement. Active motion detectors send out pulses and waves that reflect back with information relating to changes or movement in the covered grid. But the most popular motion detection for home use consists of passive infrared motion detectors that identify heat emanating from animals and humans to identify potential threats. Passive sensors tend to be more energy-friendly since they only come on when movement is detected.

Smart motion detectors.

A home automation system enables you to control many types of smart devices inside your house and out. You can customize your smart lighting, as well as indoor and outdoor motion detection sensors and lights, to work the way you want as part of your home monitoring system. Other popular home security components include window and door alarms, smart locks, and video doorbells, which feature a wireless doorbell camera. The video doorbell shows you instantly who is at the door, and even lets you talk to visitors from wherever you are.
