The following terms and definitions apply to this standard. 3.1
Based on the current television mode (PAL color system, CCIR black and white system 625 lines, 2:1 interlaced scanning), the required baseband signal is about 6MHz or higher bandwidth.
Video detection videodetecting
A detection method that uses photoelectric imaging technology (from near infrared to visible spectrum range) to perceive the target and generate video image signals.
GA/T367—2001
Video monitoring videomonitoring
Use video detection methods to monitor, control and record information on the target. 3.4
Video transmission videotransmitting
Use wired or wireless transmission media, directly or through modulation and demodulation, to transmit video image signals from one place to another, from one device to another. This system usually includes video image signals from the front-end camera to the video host device, from the video host to the display terminal, from the video host to the sub-control, from the video optical transmitter to the video optical receiver, etc. 3.5
Video controller/switcher usually refers to the video control host, which is the core device for video system operation and control, and can usually complete image switching, PTZ and lens control, etc.
Alarm image review video check to alarm When an alarm event occurs, the video surveillance system can automatically call the image related to the alarm area in real time to observe and review the on-site status.
Action with alarm
When an alarm event occurs, it triggers other devices other than the alarm device to take action (such as alarm image review, lighting control, etc.). 3.8
Synchronization of video and audio refers to the synchronous switching of video and audio signals from the same scene. 3.9
Environmental illumination environmental illumination A physical quantity that reflects the brightness of the target environment, which is numerically equal to the luminous flux passing vertically through a unit area. See Appendix A. 3.10
Picture quality picture quality
refers to the optical image quality that can be distinguished by the observer. It usually includes the number of pixels, resolution and signal-to-noise ratio, but is mainly manifested in the signal-to-noise ratio. See Appendix A.
Picture resolution picture resolution
refers to the maximum number of TV lines of the target image that can be distinguished in a certain length in the horizontal or vertical scanning direction of the display plane. See Appendix A.
Front-end device terminal device
refers to various types of equipment distributed at the detection site. In this system, it usually refers to the camera and its related equipment (such as lens, pan/tilt, decoding driver, protective cover, etc.). 3.13
Branch console
usually refers to the control and observation terminal equipment set up outside the central monitoring room. 3.14
Video motion alarm video moving detecting refers to an alarm method that uses video technology to detect changes in the on-site image and issues an alarm message once the set value is reached. 2
