Following door and window alarms, motion detectors are one of the most important security features in your home. Both indoors and out, a motion detector will alert you to anyone who is creeping around or inside your home. Many people with pets are leery of indoor motion detectors, believing that the pets will set off the alarms. The good news is that today s motion detectors are designed to be pet friendly; you won t be waking up to accidentally triggered motion detectors anymore.
Today s motion detectors are high tech, affordable, and effective. These devices have become more dependable as the technologies behind them have advanced. There is a wide range of motion detector devices available at every price level. Here are a few types of motion detectors that you can choose for your home:

Infrared sensors, also known as PIR sensors, detect radiating heat in the vicinity. These inexpensive, reliable detectors are a standard choice for many home security systems. Microwave sensors emit microwave energy. These can penetrate walls, detecting motion even in other rooms. Quite useful for home applications, these sensors are also seen in businesses, especially in automatic doors. Dual sensors, which combine both infrared and microwave technology, have the ability to distinguish between the movement of a person and that of a family pet.
Ultrasonic motion detectors can be designed to detect motions either by detecting sound waves or emitting a high frequency sound. These are very sensitive, which can also make them more expensive than other types of motion detectors. Although they are a common choice for many applications, they are not typically used for home security because of their cost.
Shock sensors work not by detecting the movement of people, but of the air. Known as glass break sensors, these detect the shock wave created as a window is broken. These are often installed along with a standard sensor near windows or glass doors. Many home intruders attempt to enter through a window, making these areas of the home in particular need of protection using motion sensors and other security devices.
While often placed near potential entry points, in truth, these sensors can be placed anywhere in the home. Many families also choose to place motion detector alarms near the bedrooms of elderly parents or young children, to be notified if they try to leave the room at night. Some emit a very loud noise, intending to scare away whoever has tripped the alarm, while others emit a quieter noise intending to alert family members to the situation.
Motion detectors are also a useful security device for your shed, RV, or other outdoor locations to scare away potential burglars. Of course, there are also motion detectors with a bright light designed for outdoor use. These are a great option for scaring away potential intruders before they attempt to enter your home.
Motion sensors are a crucial part of a comprehensive home security system. If an intruder should ever make it into your home, it is critical to be alerted to the movement as soon as possible. Thus, indoor motion sensors play a vital role in home security.
