The ADT® Monitored PIR Motion Sensor

A motion sensor can act as the focal point of your security system. When you’re away from home, your motion sensor will sense the presence of someone inside. With this type of advanced technology, you can monitor the activity at your home from anywhere, and get notified of the presence of any movement that shouldn’t be present. The ADT® monitored PIR Motion Sensor can serve many purposes within your home from monitoring the presence of intruders to managing your children’s curfew.

The ADT® Monitored PIR Motion Sensor

garage-door-sensor

The ADT® monitored PIR Motion sensor uses a passive infrared sensor to detect body heat or infrared energy. The motion sensor monitors the presence of a moving, high heat source that shouldn’t be present in the area. It does this by creating a grid in the area. Once activated, the motion sensor tracks any blockers in this grid. Then, it receives measurements of a moving object blocking grid zones, and trips the sensor thus creating an alarm.

What is a Motion Sensor?

A motion sensor is a device that is a big part of your security system. It allows you to monitor whether someone is inside of your home when they shouldn’t be. The motion sensors inside of your sensor track movement within a specific area.

Here are some features of the Motion Sensor:

  • High-traffic shutdown
  • Pet immunity up to 60 pounds
  • Lithium battery included
  • Digital signal analysis for consistent detection throughout the coverage pattern
  • Exceptional catch performance at elevated temperatures
  • Patented Multi-Level Signal Processing for accurate detection of human IR energy over a broad range of temperatures
  • Temperature compensation
  • Sensitivity adjustment to configure the sensor for “normal” or “hostile” environments



Frequently Used Together

How Motion Sensors Work

A motion sensor is a device that can detect the presence of people based on their movement. Motion sensors are often used in conjunction with a security system that alerts users of motion in and around their homes.

There are six (6) types of motion sensors:

  1. Passive Infrared (PIR sensor)
  2. MicroWave (MW)
  3. Dual Technology Motion Sensors
  4. Area Reflective Type
  5. Ultrasonic
  6. Vibration

A Passive Infrared or PIR sensor essentially detect body heat or infrared energy. These are the most common type of motion sensor. The PIR sensors can sense heat and movement throughout areas by creating a grid of the area. When specific areas of the grid become blocked by infrared energy, the PIR sensor is triggered and an alert occurs.

MicroWave or MW motion sensors send out microwave pulses that are transmitted or reflected to the sensor. As these pulses are sent out, if an object moves, the reflected wave will change, causing the sensor to trigger and an alarm to occur. Dual Technology Motion Sensors are sensors that combine both PIR and MW with the hope to eliminate false alarms as much as possible. This occurs because for an alarm to occur, you would need a change in both infrared temperature reading and microwave frequency.

Other less common types of motion sensors include Area Reflective which emits infrared LED rays to measure distance to objects, Ultrasonic which sends out pulses of ultrasonic waves to measure reflections, and Vibration which detects if there are any vibrations in the area caused by movement.

Why use the ADT® Monitored PIR Motion Sensor

The ADT® monitored PIR Motion Sensor is the perfect device to help protect your home from unwanted intruders. Due to its advanced features and benefits, it is one of the more technologically advanced motion sensors on the market today. Motion analysis is accurately analyzed within this sensor and is not subject to any signal deterioration due to noise or signal clipping.

This motion sensor also helps prevent false alarms. Many homes have pets that wander around while you’re away from home. This motion sensor comes equipped with pet immunity for pets up to 60 pounds. This means that your pets can freely move around your home without triggering a motion sensor and causing a false alarm. The motion sensor can be setup with your control panel for home and away modes. While in home mode, your security system can be armed, but your family can move freely within the home without causing an alert.

Many devices, like glass break sensors, use audio to detect an issue and trigger an alarm. With the ADT® monitored PIR Motion Sensor, you don’t have to rely on the presence of sound to identify an intruder. This motion sensor can also help monitor multiple rooms due to its 60’ coverage pattern. For example, if you have an open floor plan kitchen, you could have one device for your dining area and kitchen area. Having the ADT® PIR Motion Sensor is one of the best ways to help protect your home from intruders and keep tabs on when someone is in your home.
