Multifunctional digital monitoring device

Abstract

A multifunctional digital monitoring system belongs to the field of computer image signal processing. The structure of the present invention is divided into four ways: the first way: the camera is connected with the four frequency divider (one) through the data line, the four frequency divider (one) is connected with the host computer (one) through the data line, and the image compression card (one) is inserted into the host computer In the slot of (1), the host (1) is connected to the signal input end of the digital switcher through the data line, and the signal output end of the digital switcher is connected to the monitor. The second road: camera, four-way frequency divider (2), host (2), image compression card, digital switcher, monitor, the connection relationship is connected to the first road; the third road: the camera is connected to the host (3) through the data line connection, the image compression card (3) is inserted into the slot of the host (3), the host (3) is connected to the signal input end of the digital switcher through the data line, and the signal output end of the digital switcher is connected to the monitor. The fourth way: the mouse and keyboard are directly connected to the digital switcher through the signal line.

Description

technical field [0001] The invention relates to a digital monitoring device, in particular to a digital device for multi-functional monitoring of banks, stock exchanges, airports, stations and shopping malls. It belongs to the field of computer image signal processing. Background technique [0002] Traditional monitoring systems are all analog devices, and their main problems are: poor image quality; low reusability of tapes; small storage capacity of tapes, and a large number of tapes require a lot of space, which brings great difficulties to maintenance. Inconvenience; inconvenient query, in order to find a certain fragment, it is often necessary to search through it. [0003] According to literature search, on http: / / www.china-ideals.com / mail.htm website, the "Falcon 2000" digital video monitoring system developed by Ideals Group Co., Ltd. is controlled by a computer (compatible machine) , camera, modem, video capture card (ZK901A function card), infrared detector, cont...

Problems solved by technology

[0002] Traditional monitoring systems are all analog devices, and their main problems are: poor image quality; low reusability of tapes; small storage capacity of tapes, and a large number of tapes require a lot of space, which brings great difficulties to maintenance. Inconvenience; inconvenient query, in order to find a certain fragment, it is often necessary to search through it

However, the image quality of the monitoring system is poor, and it is impossible to improve the image quality through other technical means; the continuous storage time is relatively short, and the hard disk needs to be replaced frequently, which is troublesome to use and maintain; when querying image data, it is necessary to provide accurate query time. Quickly retrieve images based on an approximate time period; once the host computer crashes, manual intervention is required to restore normal operation
