Motion sensors are one of the best ways to secure your home. They can protect your property’s vulnerable entryways to protect you and your loved ones. However, if someone does manage to breach your exterior security, you also want to know whether people are moving inside of your house. Motion sensors can be used that have radar, photo-sensors, or infrared motion detectors. The most simple motion sensors use radar or microwave technology.

What is a Microwave Motion Sensor?

A microwave motion sensor uses electro-magnetic radiation. It emits waves which are then reflected back to the receiver. The receiver analyzes the waves that are bounced back. If there is an object moving in the room, these waves are going to be altered. The microwave detector is able to identify changes from moment to moment. Ideally, the receiver should be receiving the same waves back again and again.

    Because of the way that microwave motion sensors work, they can be either more sensitive or less sensitive. They can identify very minute changes (a totally empty house) or be calibrated to require larger scale movement (to avoid false positives).

    What Are the Capabilities of a Microwave Motion Sensor?

    Microwave sensors that are more advanced can also detect whether an individual is moving towards or away from the sensor, or moving randomly. There are ways that some trained individuals could potentially move to avoid detection by a motion sensor.

    These detectors are helpful in sensing and differentiating between the ordinary movement and intruder movement. This feature of such  sensors  makes them  highly reliable.

    Microwave sensors are completely safe to use. They can be used both inside and outside properties and be used across relatively large areas. They can also be configured to detect different types of activity, such as ignoring certain areas of the home where household pets might be active.

    What Are the Benefits of a Microwave Motion Sensor?

    • Microwave motion detectors can be used in virtually any environment, including those that are not otherwise hospitable to sensors, such as high heat environments that can set of photo-electric sensors. This makes them one of the most versatile types of sensor system.
    • Microwave detectors can go through walls and holes. Because of this they can cover a larger area of a home or commercial property, including fairly large outdoor areas. Because of this, they’re usually good for those who need to secure large areas of land.
    • Microwave detectors can be programmed in a way to reduce the amount of false alarms without having to reduce the amount of correct positives, therefore improving accuracy while also improving upon ease of use.
    • Microwave detectors are generally less expensive to purchase, even though they may be more expensive to run. They are one of the simplest systems to purchase, and also one of the oldest technologies.

    Of course, like all sensors, microwave detectors also have some negatives. They do have a number of false alarms, as things such as drapery moving could potentially cause problems. The sensors require a continuous power draw, so they may be expensive to run. They also only work at intervals rather than working continuously, by sending out signals and then receiving them. That means that someone moving fast enough could potentially evade detection.

    Weighing Microwave Motion Detectors Pros and Cons

    Not sure is microwave motion detectors are right for your home? Then it’s time for you to make a list of microwave motion detector’s pros and cons. Weighing your options is critical because this method of security will not be efficient for every home.
