Home Security Components: The Motion Sensor

People who rent as well as those who own their home have a common desire to feel safe wherever they live. Choosing the right home security system can an extra sense of peace of mind, particularly when spending an extended period of time away. Today’s home security market offers exciting new technology to those who are looking for the most innovative, convenient, and reliable ways to keep their home safe.

One of the most important components of a security system is the motion sensor. True to its name, the motion sensor detects movement around within the property and sends a signal to the security company’s monitoring station while also alerting the home security client. In addition to creating an alert when a door is opened or a window is broken, motion sensors may also be used to serve a variety of other purposes, including alerting parents when their teens arrive after curfew, alerting adults when a child enters or pet an unsafe area in the home, saving energy costs by turning lights on and off, and triggering a doorbell as visitors approach the front door.

There are two main categories of motion detectors: passive and active. Passive sensors read changes in the surrounding energy to detect changes in the area while active sensors emit infrared light, microwave, or sound waves to identify motion. Most common are passive infrared sensors, which creates divides the home into a grid once the sensors are warmed up when the system is armed. If a moving object blocks too many zones within the grid, the sensors will trigger an alarm. In Pembroke Pines ADT Security offers products which utilize infrared sensor technology. Microwave and ultrasonic sensors both detect motion by sending out pulses and measuring wave reflections off moving objects in the room. While microwave technology is capable of covering a larger area than infrared, the waves are vulnerable to electrical interference. Microwave sensor technology is also generally more expensive than infrared. Some systems may also use a combination of different types of sensors to minimize false alarms.

When considering home security technology, customers should determine the type of technology they would prefer to use and seek out service providers that offer these options. Not all alarm systems are created equally; therefore, it is important that the customer know his or her technological needs before purchasing a system.
