Day/night megapixel cameras
Ahrensburg, Germany
During normal lighting conditions, the IR-cut filter is positioned in front of the imaging sensor. This results in high quality color images. When the ambient light level decreases, the automatic exposure control on the Basler IP camera moves the mechanical IR-cut filter aside and replaces it with a clear filter to keep the correct back focal length. Without the IR-cut filter in front of the sensor, the camera will shift into a black and white mode that allows operation at a minimum illumination and enabling full night vision capability.
An ultra-compact, all-metal housing with a size of 89.8 mm x 29 mm x 44 mm and a weight of only 230 grams makes these the smallest day/night IP cameras in their class. These characteristics contribute to a flexible, easy installation.
"CCD sensors are extraordinarily sensitive to near infrared light, and this makes them a perfect fit for true day/night cameras. Because CCD sensors are not packed with circuitry as CMOS sensors are, they have a better "fill factor" resulting in a greater sensitivity to light and making them more suitable for low light conditions. By using this state-of-the-art technology together with our extensive experience in vision technologies, we are able to provide professional quality imaging for all lighting conditions", states Gerrit Schreiber, product manager at Basler Vision Technologies.
