2、 Main control system
Due to the wireless transmission scheme of digital microwave transmission, the main control system can use an ordinary computer for access control and video recording, and only need to install the corresponding software in the existing computer or directly access through the browser. If the image of the main control center needs to be on the TV wall, it needs to be equipped with a corresponding decoder to decode before it can be on the TV wall. In order to facilitate the user's understanding of the system functions, this paper describes the various intelligent monitoring functions of the system from the user's two use environments of the system.
1. Functions of central monitoring room:
The main control room of remote wifi image transmission module is the signal control and information exchange center of the whole system. The system has the most comprehensive functions, which are simply described as follows:
a. It can display audio-visual information of any one or more monitoring points in real time for real-time monitoring.
b. The display effect and recording speed of any camera can be set to achieve the best effect.
c. Images of one or several important monitoring points can be stored in multiple modes.
d. It can back up and play important video materials.
e. It can perform various intelligent retrieval and playback of video data.
f. It has powerful network transmission function, and can transmit various monitoring signals to the WAN to realize network monitoring.
g. By setting up a digital intelligent control host, the monitoring signal can be uploaded to the Internet network to achieve remote monitoring.
2. Functions of other network sub control terminals:
Other network sub control terminal equipment mainly refers to the sub control computer installed at the location of unit leaders or system management personnel. As the network sub control terminal, three conditions must be met to realize the sub control management function. Including: the sub control computer at the sub control end must be connected with the central digital master control equipment; Install and run special sub control software on the sub control computer; Enjoy the administrator's authorization and password.
Specific functions are as follows:
a. The video images of all monitoring points can be viewed at any time through the network.
b. The PTZ and lens of each monitoring point can be remotely controlled through the network and sub control software to get rid of regional restrictions.
c. You can log in to the monitoring host and view the previous video data at will.
d. The color, contrast and saturation of the front camera can be adjusted.
