But keep in mind, most people purchase more than one motion sensor to cover different areas of their home or property. Single sensors usually cost less than $50.
To trigger an alarm or light when someone walks through the entryway, a microwave or infrared sensor may be more useful.
#MOTION SENSOR LIGHT SWITCH WINDOWS#
Vibration sensors are useful for use with windows and doors, but less so for detecting movement in an open area. If you want to increase security inside your home by placing motion sensors indoors, think about where you’ll mount your new sensors. These models are durable, and can handle extreme temperatures and precipitation.Ī larger area is usually in question when monitoring the exterior of a home so consider motion sensors that have bigger detecting ranges. If you are looking to prevent people from coming close to your home in the first place, you may want to invest in outdoor motion sensors. What do you intend to do with the sensor? Are you concerned about potential break-ins? Or are you more focused on people coming close to the property at all? If a system includes indoor sensors, these will be deactivated while outdoor sensors will continue working. Many detectors offer users the option of enabling this function, which tells the motion sensor that someone is already in the home. This type of sensor is activated by the vibrations that occur due to movement.
#MOTION SENSOR LIGHT SWITCH VERIFICATION#
The double-step verification process reduces the chance of false alarms. Some motion sensors utilize a two-step process for detection that includes both passive infrared and microwave technologies. The biggest drawback to microwave motion sensors is that they’re prone to false alarms. Intrusion by a moving object alters these frequencies, triggering an alarm. The sensor monitors the frequency of the reflected waves. This type of motion sensor detects movement from a distance by using microwaves fill a target area. Infrared is useful for monitoring large areas, and is sensitive enough to detect movement. Passive Infrared sensors use body heat to detect movement and potential intruders. This is one of the most common types of motion sensors. Your needs will dictate which type is best for you and your unique situation. There are various types of motion sensors on the market. Some even mimic a dog to drive away intruders. Some motion sensors can make different noises when people approach.
