Starlight series CCD camera is one of the special series of multi-purpose cameras developed by B & T. By using frame accumulation technology, starlight camera provides surprisingly low brightness performance and can compose images in almost complete darkness.
In these cameras, the concentration of photons on the CCD sensor is 2 to 128 times ( 1 to 2 seconds) longer than the maximum exposure time ( 1/60 or 1/50 of a second) of a conventional CCD camera . As a result, the minimum illumination of the camera to produce a usable image is reduced by 2 to 128 times.
Using a starlight camera with frame accumulation technology, users can see color images under starlight conditions ( 0.0035Lux ), and black and white images under cloudy starlight conditions ( 0.0002Lux ). (Such as light pollution) is sufficient to produce good color exposure.
The starlight camera can also expand the effective range of using infrared. Using frame cumulative exposure, the range of influence of an infrared light source can be extended 128 times. If a starlight camera is used, an infrared lamp designed to illuminate a target 10 meters away can extend its working range To a few hundred meters.
