Genuine Canon 95° Angle of View Lens
Canon's world-wide fame in optical technology means that this same expertise is seen in the superb lens fitted to the VB-S31D. In addition to a wide 95° viewing angle, the UD, aspherical elements and high refractive index mean this lens delivers excellent image quality while at the same time possessing the smallest form factor in its class, all in a compact size.
Another benefit this lens brings to the user is the mitigation of environmentally caused focus shift. Wide temperature ranges to which the camera may be exposed can result in thermal expansion of the lens barrel. This affects the lens' refractive index, causing focus shift. This problem is largely eliminated in the VB-S31D.
Class Leading Low-Light Performance
Frequently, challenging low-light situations are found in surveillance locations. The ability of a security camera to capture the highest quality video possible in such conditions is very important. The VB-S31D combines a high sensitivity sensor, bright lens, enhanced noise reduction, and video quality optimization to deliver Full HD video with low-light performance at the top of the compact HD class in Canon testing. What this means is color video from .45 lux down to .01 lux* and black/white video from .025 lux to .007 lux.** These impressive numbers translate into higher quality video from VB-S31D cameras mounted in the most demanding locations.
