With the proliferation of low-cost digital cameras able to shoot video, it is possible to use the output of such a camera to detect motion in its field of view using software. See details. When the Motion Detector is removed from the wall, the Alarm Station will trigger a tamper alarm and send an alert to your smartphone. An ultrasonic transducer emits an ultrasonic wave (sound at a frequency higher than a human ear can hear) and receives reflections from nearby objects. Xodus Innovations HS4370B Battery Powered Adjustable Motion Sensor Alarm with Remote Control. The best thing about our best motion alarms for home security is that they’re wireless and easy to install yourself. When you have a motion detector installed, you can rest assured knowing your easy-to-install motion sensor alarm will let you know when something’s amiss. Specialized systems are more expensive but have either increased sensitivity or much longer ranges. A motion detector is an electrical device that utilizes a sensor to detect nearby motion. One potential drawback of ultrasonic sensors is that the sensor can be sensitive to motion in areas where coverage is undesired, for instance, due to reflections of sound waves around corners. They have the ability to detect over large areas completely because they can sense through walls and other obstructions. From an outdoor motion sensor light with alarm to an indoor system with multiple sensors, you have plenty of options. Often disguised as a smoke detector, they hide in plain sight so they won’t be tampered with.

Ceiling Alarms: Ceiling alarms are simple and effective. Portable Alarms: A portable motion detector has two parts: the motion detector and a portable receiver. [1] This distinguishes it from the electric eye for instance (not usually considered a motion detector), in which the crossing of a person or vehicle interrupts a visible or infrared beam. Alarm Station will ring a local security siren and send an instant alert to your smartphone whenever it detects motion, keeping you aware of what's going on at home from anywhere. An active electronic motion detector contains an optical, microwave, or acoustic sensor, as well as a transmitter. In such smart lighting systems, energy is conserved by only powering the lights for the duration of a timer, after which the person has presumably left the area. Set to detect even the slightest movement, some motion sensor alarms actually connect to fire alarms and security cameras, too! Such a detector may also trigger a security camera to record the possible intrusion. Installing a motion detector or motion sensor alarm is the quintessential way to stay alert when someone (or something!) It takes less than an hour and just a few batteries to secure all your home’s entry points from invasion. These systems also come with a remote and panic button.
