Just set the parameters of each 5-megapixel model with a fixed focal length can be increased by adjusting the rings when the lens with the camera installed at the facility surveillance. To improve the quality of video HF35SR4A-1/HF50SR4A-1 and optics with ARD HF35SR4A-SA1/HF50SR4A-SA1 allow necessary to apply optional filters. For this purpose lenses equipped with standard thread M35/M40 for screwing the filter. For example, in outdoor conditions video to compensate for the excess brightness of the sky, with the active sun is advisable to use a gradient filter, which allows not only to balance the illumination of the scene, but also to prevent flare matrix cameras.
To ensure correct operation of the lens series of HF35 (1950) SR4A with cameras such as "day / night" allows infrared (IR) correction filter, which is a special multi-layer coating applied on the lens. Unlike conventional optics without IR correction, which is unable to compensate for the different wavelengths of the day and night lighting and leads to a shift in focus when switching camera modes between "day" and "night", the new lenses correct this deficiency, preventing defocusing the image. This is especially important for video surveillance, high-resolution, where a slight shift of focus would lead to loss of informative videos, and the impossibility of its use for identification of state. numbers of machines and other important tasks.
Robust new products reduces their sensitivity to vibration, shock and temperature fluctuations from -10 to 50 ° C, and C-metal thread securely attaches the lens to the cameras from manufacturers such as Arecont Vision, AXIS, Pelco, Sanyo and others . In this new lens will work effectively in a video security, recognition, license plate vehicles, including, in poor visibility and high flow rates, in systems Learning cargo, surveillance complex technological processes, as well as in machine vision systems.
New 5-megapixel long lens with IR correction HF35SR4A-(SA) 1 and HF50SR4A-(SA) a company Fujinon already arrived at the warehouse company ARMO-Systems, and their retail price is 733 and 833 dollars respectively.
