How is the network monitoring system composed?

In the analog era, the transmission part generally adopts coaxial cable and optical cable, which is composed of a closed-loop system, that is, only this unit can be provided for use.

A typical closed-circuit monitoring system is mainly composed of four parts: camera part, transmission part, control and recording part, and display part. First, the camera part is the cutting-edge part of the TV surveillance system and the "eye" of the whole system.

The video surveillance system consists of five parts: front-end acquisition, transmission, control, display and recording.

The hardware composition of the security monitoring system usually includes the following aspects: Camera: Installed in the area that needs to be monitored, and the monitoring is completed by capturing images. Video server: used to manage and store images or videos taken by cameras.

The main technologies adopted by network monitoring are network monitoring and communication analysis technology. The specific composition of the network monitoring system can be divided into the following parts. Computer hardwareAlthough some products require special hardware, most of them work on standard network adapters.

Network video surveillance components: The network video surveillance system is generally divided into three levels: front-end access, media exchange and user access, specifically composed of front-end coding unit, central business platform, network video unit, client unit and decoding unit.

How to build a remote surveillance camera system

First, enter the IP of the router in the browser address bar to establish a connection, and set the LAN parameters and subnet mask after logging in, and the WAN login link. Then set the router to intranet address forwarding, which we usually use port 80. Then enter the domain name of Peanut Shell on the computer's software.

Choose a suitable camera: Choose a suitable camera according to actual needs. There are indoor and outdoor cameras. You can choose wired or wireless cameras according to your needs, taking into account factors such as image quality and function. Install the camera: Fix the camera in the appropriate position to ensure that the field of view covers the area that needs to be monitored.

Mobile phone remote surveillance camera setting method First of all, we need to find a network remote monitoring system client corresponding to the mobile phone system and install it on the mobile phone. Log in to the network remote monitoring system client, click the icon to add the device, and enter the username and password of the home network surveillance camera. Left-click to save.

Download and install the corresponding cloud vision mobile phone network remote monitoring system client 2Log in to the main interface of the mobile phone monitoring system, click the "Add Device" icon, and enter the Yunshitong number 3 of the home network camera. Click the "Save" button to open the "Device List" interface and display the device name 4.

How to set up remote monitoring? It can be done in two steps

1. First, enter the IP of the router in the address bar of the browser to establish a connection. After logging in, set the LAN parameters and subnet mask, and the WAN login link. Then set the router to intranet address forwarding, which we usually use port 80. Then enter the domain name of Peanut Shell on the computer's software.

2. First of all, make sure that the Hikvision device is connected to the network and can be accessed externally. SoAfter that, follow the following steps to set up mobile phone remote monitoring: On the web interface of Hikvision device, enter "Device Management" u003e "User Management" and add users with remote access rights. Remember the user's name and password.

3. Then, in the [Select Remote User] section, enter the account name and password to allow remote access. Establish a remote desktop connection. On the monitored computer, click the Start menu, search for "remote desktop connection" or directly enter "mstsc", and you will see the [remote desktop connection] program and open it.

4. How to set up the mobile phone remote monitoring camera First of all, we need to find a network remote monitoring system client corresponding to the mobile phone system and install it on the mobile phone. Log in to the network remote monitoring departmentUnify the client, and click the icon to add the device, and enter the user name and password of the home network surveillance camera. Left-click to save.

5. First of all, you need to place the camera and connect it correctly to the monitoring settings. Because the connection between the mobile phone requires the help of the network, the router is connected to the computer, and after debugging, one network cable is installed on the router, the other is installed on the camera, and then the power supply is connected.
