Sharp's security camera captures color video when it's pitch black
Cat burglars, beware: Sharp has a security camera that can shoot in the dark and in color.
The Infrared Color Night-vision Camera, model LZ0P420A, is the first security camera that can record color footage in zero-light environments, according to Sharp.
The camera works by shining a near-infrared light on a target area so that its 1/3-inch, 1.3-megapixel CCD chip can capture color images. It can record footage in 1280 x 720 resolution at 30 frames per second.
However, a person in the area wouldn’t be able to see a thing.
“The camera analyzes the reflections of near-infrared light to retrieve the actual colors of a scene,” Sharp spokeswoman Miyuki Nakayama said.
The CCD chip was developed with Japan’s National Institute of Advanced Industrial Science and Technology (AIST), which had been working on color night-vision cameras for several years. Since it only has one chip, the camera is the size of a conventional security camera. It weighs about 940 grams.
Beyond security surveillance to deter theft, the camera could be used in facilities such as hospitals and nursing homes.
Sharp said it will begin sales of the camera on Nov. 28 and is targeting production of 4,000 units per month, with availability initially in Japan. The price would be around ¥150,000 ($1,325) to ¥200,000, which would be about 1.5 to two times as much as conventional security cameras, according to the company.
A prototype of the camera was shown off at the Ceatec trade show outside Tokyo last month, where Sharp also displayed a car camera system that lets drivers have a virtual bird’s eye view of their surroundings.
Infrared light is often used in nature documentaries to film animals at night, but the footage is monochrome and often grainy.
Sharp’s camera follows several security cameras released by Sony that also use infrared light and are designed to work in very low light conditions. They can reveal faces and vehicle license plates by using exposure-compensation technology, according to Sony.
