Description of Bosch VC86775T 0.33-inch B/W Camera with 4mm Fixed Lens

This monochrome camera utilizes a 0.33-inch CCD (charge-coupled device) sensor, with 512-horizontal by 492-vertical active picture elements according to the EIA (Electronic Industrial Alliance) standard. This produces a resolution of greater than 380 TVL (TV-lines) with a S/N (signal to noise) ratio of better-than 48 dB. The Axis VC86775T comes with a standard CS-mount, 4mm (F1.2) lens with a light sensitivity of 0.2 Lux. Powered by 9.6 to 27 volts DC (via system cable), this unit uses a telephone-style (modular) connector. This camera can operate in temperatures from -20 to 45-degrees Celsius.

Technical Features:

• Sensitivity: down to 0.2 Lux for acceptable picture
• Resolution: greater than 380 TVL
• S/N ratio: 48 dB
• Dimensions: approximately 7 x 6 x 7 centimeters (W x D x H)

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.
