4 en | Glossary of CCTV Terms Camera, DVR, and VIP products AWB Auto White Balance: A feature that allows a color camera to automatically adjust its output color to give a natural color, independent of the lighting used. Balun Baud Bilinx Bilinx address Biphase Bit/s BLC B Short for Balance/Unbalanced. A device that converts a balanced video signal (e.g. as used on twisted pair) line to an unbalanced signal (e.g. as used on coax). In a balanced line both wires are electrically equal. In an unbalanced line one wire has different electrical properties than the other. Unit of measure for the speed of data transmission. A communications protocol that allows remote control, configuration, and updates to be performed over the video cable (Coax or Passive UTP). The address may be set locally using the Bilinx Configuration Tool for Imaging Devices (CTFID) or remotely using the Fast Address function (see Fast Address). Pan/Tilt/Zoom protocol for Bosch products. Bits per second, the actual data rate. Back Light Compensation: Selectively amplifies parts of the image to compensate for large contrast differences when only a portion of the image is brightly lit (e.g. a person in a sunlit doorway). C Cable Category Application and bandwidth rating system for UTP cabling. Categories 1 through 7 are based on EIA/TIA-568-B standards. Category is typically abbreviated CAT. UTP Category 5, 5e, 6, and 7 are used for Ethernet data cabling applications. Ethernet wiring distances are limited to a maximum of 100 m (328 ft.) when using UTP wiring. Cable Compensation A technology that prevents image degradation caused by signal losses when transmitting video over long cable lengths. CCD Charged Coupled Device: A type of solid state image sensor used in CCTV cameras. The sensor converts light energy into electrical signals. CCD Format Indicates the size of the camera sensor used. In general, the larger the sensor, the more sensitive the camera and the better the image quality. The format is quoted in inches, for example 1/4 or 1/3 inch. CCTV Closed Circuit TeleVision: A video system that transmits television signals over a closed (nonbroadcast) system. CF CompactFlash: Digital storage media - used in computers, digital cameras, and Personal Digital Assistants (PDA) in the form of CF cards. CIF Common Intermediate Format: Video format with 352 × 288/240 pixels. Color Temperature A measure of the relative color of illumination. Generally used to specify the color balance correction of a camera to achieve a natural color image. CTFID Configuration Tool for Imaging Devices: Bosch software used to configure and update cameras and other remote devices over video cable using Bilinx, and to save them for later use.
