The VB-C50iR comes with a varifocal lens, with a range between 3. 5 and 88. 3 millimeters that allows an amazing 26x optical and 12x digital zoom. For extreme low-light situations, this camera has a 1/30 per second shutter speed, a light sensitivity of one Lux with its motorized IR-cut (infrared) filter, and visibility in no-light conditions up to 10 feet away using the IR light illuminator. The Canon VB-C50iR has automatic adjustable positioning with a 340-degree pan, and 100-degree tilt range. The VB-C50iR also features automatic image capture with 15MB of internal storage capacity for still image recording, which can be activated by schedule, motion detectors, or contact sensors. This system supports the Canon Multi Terminal VB-EX50 Module for connecting external speakers, cameras, sensors ,and alarms and can operate in temperatures from zero to 40 degrees Celsius. Technical Features: Sensitivity: down to one Lux Frame rate: up to 30 frames per second (fps) Resolution: up to 640 by 480 pixels Zoom: up to 26x optical and 12x digital Pan/Tilt range: 340-degree pan range, 100-degree tilt range Dimensions: approximately 10 x 13 x 11 centimeters (W x D x H) The Canon VB-C50iR provides you with a reliable, easy-to-use camera with unparalleled zoom potential, making it a powerful addition to any security system. You can define 20 position pre-sets as part of a scheduled tour, and you can catch the most important action by setting your camera so that it is triggered when motion is detected in one of four areas within the camera's view. Quick and easy to install, this camera comes completely assembled and ready to use. Users should note, however, that the CCD sensor may become permanently damaged if exposed to long hours of direct sunlight or halogen light. About Surveillance Camera Technical Features Lux rating is the measurement used to indicate how sensitive a camera is to light, and stands for the level of light reflected off a piece of paper by a candle from one meter away. Thus a sensitivity of three Lux would mean a camera could generate an acceptable picture of a piece-of-paper-sized object that was illuminated by the equivalent of three candles from one meter away. The lower the Lux level, the better the camera's ability to work in low-light conditions. The camera's resolution should be greater than or equal to the resolution supported by the system's recorder or monitor. The S/N, or signal to noise ratio, is an important measure of a camera's quality. A poor camera, low-light conditions or poor wiring causes "noise" which consumes processing power and disk space. A camera with a wide dynamic range is ideal, especially for recording areas in which both indoor and outdoor light are present. CCD (charge-coupled device) sensors provide high-quality images that are less susceptible to noise. CMOS (complimentary metal-oxide semiconductor) sensors offer less image quality, but are usually more cost-effective and energy efficient. About Pan/Tilt Cameras A Pan/Tilt Camera has the ability to pan ("move" horizontally), or tilt ("move" vertically). IP cameras often have pan/tilt capability. A pan/tilt camera is ideal for monitoring of situations that need a continual real-time adjustment of the views. About Auto Zoom Cameras An auto-zoom camera can be remotely controlled and allows the monitor to manually zoom in on areas for clearer viewing. An auto-zoom camera, combined with a mount that has pan and tilt functionality, can be used to construct a high-end surveillance system. About Infrared Cameras An infrared camera uses an infrared illuminator for low-light and nighttime viewing. Typically designed with fixed focal lengths, infrared cameras provide black and white images of nighttime viewing, and many have color capability for daylight use.
