A Deep Dive into Avigilon's Adaptive IR


May 5, 2023


Infrared (IR) technology has become a crucial component of modern surveillance cameras, providing enhanced visibility and performance in low-light conditions. In this blog post, we will explore the workings of IR technology in cameras and highlight Avigilon's innovative Adaptive IR feature, which sets it apart in the realm of video surveillance.

Understanding Infrared Technology in Cameras

Infrared technology leverages the invisible portion of the electromagnetic spectrum, known as infrared light, to illuminate scenes in low-light or complete darkness. While the human eye cannot detect infrared light, specialized cameras equipped with IR sensors can capture this light, resulting in clear and detailed images even in challenging lighting conditions.

In surveillance cameras, IR technology typically works in tandem with two main components: an IR LED array and an IR-cut filter. The IR LED array emits infrared light, which illuminates the scene, while the IR-cut filter, which is placed in front of the camera sensor, ensures accurate color reproduction during daylight hours by blocking infrared light. In low-light conditions, the IR-cut filter automatically moves away from the sensor, allowing the camera to utilize the infrared light for improved visibility.

How Avigilon's Adaptive IR Stands Out

Avigilon's Adaptive IR technology elevates the performance of infrared cameras by intelligently adjusting the intensity and distribution of infrared illumination based on the scene and the position of objects within it. This innovative feature offers several key advantages over traditional IR cameras:

Improved Image Quality: Adaptive IR technology ensures that objects in the camera's field of view are evenly illuminated, preventing underexposure or overexposure, which can lead to loss of detail. This results in crisp, clear images regardless of the distance between the object and the camera or the level of ambient light.

Enhanced Privacy: By dynamically adjusting the intensity of the IR illumination, Adaptive IR technology minimizes light spillage onto neighboring properties, reducing the likelihood of privacy concerns or light pollution.

Increased Efficiency: Traditional IR cameras often operate at a fixed level of illumination, which can consume more power than necessary. Adaptive IR technology adjusts the intensity of the IR illumination based on the scene, reducing power consumption and extending the lifespan of the IR LEDs.

Better Performance in Complex Scenes: In scenes with varying levels of light or objects at different distances, traditional IR cameras can struggle to provide adequate illumination. Adaptive IR technology continuously analyzes the scene and adjusts the IR illumination accordingly, ensuring optimal performance even in challenging environments.

Avigilon's cameras, such as the H5A and H5SL cameras, are equipped with Adaptive IR technology, making them ideal choices for a wide range of applications, including perimeter security, parking lots, and critical infrastructure protection.


Infrared technology has revolutionized the capabilities of surveillance cameras, enabling them to provide clear, detailed images in low-light conditions. Avigilon's Adaptive IR technology takes this a step further, intelligently adjusting the intensity and distribution of infrared illumination to optimize image quality, enhance privacy, and improve efficiency. As the video surveillance industry continues to evolve, innovations like Adaptive IR will play a crucial role in ensuring that our homes, businesses, and public spaces remain safe and secure.
