Vicon IP camera with digital noise reduction

547 Vicon Industries has added three new models within its I-Onyx line of IP cameras. The VN-856 series, which includes colour, day/night and wide dynamic range models, all feature Digital Noise Reduction (DNR), allowing the cameras to provide superior performance in low light conditions. The cameras apply DNR algorithms to process the video prior to transmission, greatly reducing the noise that typically plagues video captured in low light. Vicon says the result is cleaner images with more discernable detail, as well as smaller video files that require lower bandwidth for transmission and less storage space.

The cameras offer several high-end features that provide system designers with added flexibility when determining camera placement within an installation; for instance, programmable privacy masking zones that allow for sections of the image to be shaded out so that the operator may not view video within these boundaries. A mirror setting allows for aiming the camera at a mirror, rather than the desired scene, and the captured image is automatically reversed for viewing purposes, returning it to its proper orientation. A sensitivity setting allows the user to increase the camera's sensitivity as it detects the light levels in dark or night environments.

All three cameras provide a resolution of 540 horizontal lines and employ ViconNet MPEG-4 compression that optimises both file size and picture quality. Power over Ethernet (PoE) eliminates the need for a separate power supply.
