Pros and Cons of Microwave Motion Detectors

Microwave motion detectors are great ways of making sure people don't go where they're not supposed to. Much like the sensors you see in movies surrounding priceless diamonds, microwave motion detectors can tell when an unwanted guest has crossed a forbidden barrier using microwave energy. Any motion that enters that area of detection immediately activates your alarm, alerting you and your home alarm system of the intruder.

The sensor system can be contained in one unit or two, known as monostatic and bistatic respectively. Monostatic units detects motion through a 400 foot linear beam whereas bistatic offers a larger range of detection of up to 1,500 linear feet. The downside to bistatic is that it does not allow the owner to define the area as precisely as monstatic, making it prone to false alarms. Depending on what your particular situation is, you may feel the need to have one or the other. If you're uncertain, talk to a home security expert and explain the dimensions of the area you want to install your motion detector in.

One of the pitfalls of microwave motion detectors is that it can have dead zones when metal is involved as it is one of the only materials it cannot penetrate. Also, as it can penetrate walls, it might be triggered by things objects blowing in the wind or even fluorescent lighting due to the light particles it emits. It also can be a pain if you or a family member forgets that the sensor is activated or you forget to keep a pet locked out of the room that it's in.

When you get a microwave motion sensor, it's often recommended by professionals that you pair it with an infrared sensor. This way, the microwave motion sensor will be able to detect forward motion and the infrared radiation sensor will be sensitive to lateral motion. With both of these systems employed, it would be nearly impossible for a burglar to fool it by walking slowly or trying to take advantage of dead zones.

Another good addition to your microwave motion detectors would be magnetic detectors on your doors and windows. By having these sensors on your doors and windows, you greatly decrease the chance of someone entering the house before they even get a chance to set of the motion detectors. Glass breakage alarms are another way that you can prevent the intruder from getting too far into your home, as well.

The important thing to remember when it comes to using any of these alarms is that there is safety in numbers, even when it comes to home security systems. Of course, it's also imperative to note that many of these systems are prone to false alarms, so they must be properly calibrated. Even when done correctly, it's still likely that the owner will receive a few false alarms. The more detectors you have, the more false alarms there will surely be, so don't install more than you're prepared to deal with.
