Infrared security devices are essential components of modern security systems, providing reliable detection of unauthorized movement. These devices use infrared technology to sense heat signatures, making them highly effective in various environments. Passive Infrared (PIR) sensors detect changes in infrared radiation, while active infrared sensors emit beams and monitor for interruptions. Both types are widely used in residential and commercial settings, offering a robust solution for intrusion detection.

Types of Infrared Security Devices

Infrared security devices come in several forms, each designed for specific applications. The most common types include:

• Passive Infrared (PIR) Sensors: These detect heat emitted by moving objects and are commonly used in motion-activated lights and alarms.
• Active Infrared Sensors: These emit infrared beams and trigger an alarm when the beam is interrupted, often used in perimeter security.
• Dual Technology Sensors: Combine PIR and microwave or ultrasonic technology to reduce false alarms.

Applications of Infrared Security Devices

Infrared security devices are versatile and can be used in various settings:

• Home Security: Protect entry points like doors and windows with motion-activated alarms.
• Commercial Security: Monitor large areas such as warehouses and offices for unauthorized access.
• Outdoor Security: Use weather-resistant infrared sensors to secure perimeters and driveways.
