Different Motion Sensor Models & Their Features
Motion sensors are essential in modern security, automation, and energy management. They detect movement and trigger responses such as lighting, alarms, or notifications, and protect your property.
At Thompson Security, we help better understand differences in various models or types of motion sensors commonly used today. Knowing how passive infrared (PIR), microwave, dual-technology, ultrasonic, and AI-enhanced sensors work will guide you in selecting the most effective technology for reliable motion detection.

How Motion Sensors Detect and Respond to Movement
Motion sensors use different technologies to detect movement and respond accordingly:
- Detection: PIR (passive infrared) sensors sense changes in heat, while ultrasonic sensors send out sound waves and listen for their echoes. Some motion detectors combine these methods to improve accuracy.
- Signal Processing: Once movement is detected, it runs algorithms to filter out false alarms caused by environmental changes, ensuring only real motion triggers a response.
- Triggering: When motion is detected, the system activates lights, alarms, cameras, or other smart devices to protect your property. These systems are customizable to suit your specific needs.
Types of Motion Sensors and Their Features
Motion sensors detect movement to trigger alarms, lighting, or notifications in security and automation. The types include
Passive Infrared (PIR) Sensors
Detect body heat by sensing infrared radiation, effective up to 30 feet with passive operation.
Microwave Sensors
Emit microwaves and measure reflections to detect movement, even through walls or objects.
Dual Technology Sensors
Combine PIR and microwave sensors, reducing false alarms with motion detector.
Advanced Ultrasonic Sensors
Use high-frequency sound waves that bounce back to detect motion in three dimensions.
Tomographic Motion Detectors
A mesh network uses radio waves to detect movement over wide areas through obstructions.
Optical Motion Sensors
Use cameras and algorithms to detect detailed movement, size, and direction for surveillance.
Smart Vibration Sensors
Detect mechanical vibrations or acceleration, ideal for equipment and structural security monitoring.
AI-Enhanced Motion Detection
Combine AI and sensors for better accuracy, fewer false alarms, and advanced threat analysis with us.

Choosing a Motion Sensor That Best Fits Your Business
Choosing the right motion detectors depends on your specific needs and environment. For indoor use, passive infrared (PIR) sensors are reliable and cost-effective for detecting human presence. If you need to detect movement through walls or objects, microwave or tomographic sensors are better options. Dual technology sensors offer high accuracy by combining methods, reducing false alarms.
For detailed monitoring, optical sensors integrated with cameras work well. Consider vibration sensors for equipment monitoring. Also, factors like installation location, sensitivity requirements, and budget matter for selecting the best type.
Residential & Commercial Applications of Motion Detectors
Motion sensors have a wide range of applications across various fields. In home security, they provide early detection of intruders and automate lighting for convenience and safety. Smart homes use motion detectors to optimize energy use by controlling lights and thermostats based on occupancy. In commercial and industrial settings, they help manage access control, monitor equipment, and enhance security systems.
Healthcare facilities use them for patient monitoring and fall detection. Additionally, the systems support automation in traffic control, retail analytics, and environmental monitoring, making them versatile tools for improving safety and efficiency.
