FreezeFrame was the first video-based system for fear conditioning. It has become the standard in its field combining the sensitivity of the human observer with the objectivity and high throughput of automation. While infrared beams can detect gross movements of an animal from one part of the cage to another, FreezeFrame can detect the minute movements of grooming, sniffing, turning and rearing. The proprietary motion detection algorithm filters out shadows, light flicker and camera noise, and detects movements as small as 1 mm.
