Rapid Pulse Illumination Technology minimizes IR LED glow by pulsing LEDs for just 1/4 second
Cuddeback's exclusive Rapid Pulse LEDs reduce unwanted LED glow. The LEDs are not on for longer than 1/4 second* which means a dramatic reduction in the visible glow that comes with most LEDs.
*While taking night videos, LEDs are on longer.
Another Cuddeback innovation, Rapid Pulse Illumination Technology

"This is one more clever feature that you won't find on other cameras. The reduced IR glow means it's harder for others to see your IR camera and yet itstill provides long illumination range."
