Motion Detectors For Home Security

Posted in Home Security

Many homeowners concerned about security install motion detectors on their property to deter would-be burglars and other intruders. They are also sometimes used to monitor the activities of children and pets. 

Motion detectors can be quite complicated systems, but are used more or less the same way in home security situations. Outside the home, the motion sensor is usually hooked up to a camera or flood lights, which come on when the sensor detects motion. Inside the home, motion sensors can be connected to windows or doors with alarms that sound if the sensor detects movement. They can also contact your smart phone or local law enforcement. 

Here are two types of motion detectors commonly used in home security systems. 

Passive Infrared Detectors 

Passive infrared systems are the most commonly used by homeowners because they’re reliable and affordable. They work by detecting changes in temperatures in a given area. Passive infrared sensors do not emit energy of their own. 

Active Motion Detectors 

Active infrared sensors, on the other hand, use optics, sound waves or radiation to detect motion.  The main difference between passive infrared detectors and active motion detectors is that active detectors emit some sort of energy; passive detectors do not. Active motion sensors are often used in commercial settings to open doors or ring bells whenever someone approaches the threshold. 

Motion detectors are not completely foolproof when it comes to catching intruders. They can have gaps in their coverage, and can sometimes be blocked by radio signals or light waves. In any case, it’s important to consult a home security specialist if you have any doubts.


Motion Sensors Have Many Uses

Posted in Home Security

Motion detectors play an important role in many home and business security systems and home and business automation systems.  For most businesses and homeowners, motion sensing outdoor lighting is the first thing that comes to mind when thinking of motion detectors, but in addition to security motion detectors have many more applications including energy savings, home automation, and remote monitoring.

Outdoor motion activated lighting detects motion outside of your home or business and illuminates the area, increasing personal safety as family members and employees enter or leave the premises.  The illumination also discourages would be intruders.  In addition, the lighting is programmed to turn off automatically after a set period of time, saving energy costs.

Outdoor motion sensors can be used in additional security applications such as monitoring driveways and entryways or other areas around your home or commercial facility and sending an alert when vehicles or visitors are arriving at your home or business or entering one of these areas.

Indoors, motions detectors can be integrated with your security system to sound the alarm when unwanted intruders are detected inside your home or business.  In addition, motion detectors are used as occupancy sensors to automatically activate and extinguish lights or other appliances.  They save energy by automatically ensuring that the lights or appliances are only turned on when needed.

Motion detectors can also integrated with remote monitoring systems to help monitor elderly family members, babies, or to keep an eye on your home or office while you are away.  Talk to an experienced security and automation company about how motion detectors can help meet your needs.
