Overview:

In order to ensure the safety of the factory's anti-theft alarm video surveillance, network cameras are installed at the entrance to record daily personnel and vehicle entry and exit situations, monitor valuable equipment, and better prevent theft. Real time video recording is provided for future reference, providing strong evidence for evidence collection.

1、 Scope of application

Factory network monitoring/enterprise group network monitoring (headquarters/branch)/remote office monitoring, etc

2、 Requirement analysis

1. Financial Office, Key Office Area Monitoring

The finance department and key office areas monitor personnel activities through network cameras, infrared probes, etc. to prevent illegal intrusion; Install network cameras in key areas for 24-hour uninterrupted video monitoring, with alarm linkage recording. Some areas can use infrared network cameras and high-speed ball cameras; It can achieve centralized management and control of all monitoring areas, as well as unmanned storage work, reducing labor intensity and investment costs;

2. Warehouse monitoring

Installing infrared night vision network cameras in the warehouse allows duty personnel to real-time monitor the situation inside the warehouse, playing an important role in theft prevention, fire prevention, and improving safety management levels.

3. Monitoring of employee work status

The working condition of employees directly affects production quality. Installing network cameras in the lobby can assess and evaluate the status of employees, observe their duty and production situation within the prescribed range. By utilizing the recording function of the system, the work status of employees can also be saved as a basis for assessment and evaluation.

4. Monitoring of gates and important equipment

In order to ensure the safety of the factory's anti-theft alarm video surveillance, network cameras are installed at the entrance to record daily personnel and vehicle entry and exit situations, monitor valuable equipment, and better prevent theft. Real time video recording is provided for future reference, providing strong evidence for evidence collection.

3、 Scheme design

Utilize the broadband network already deployed within the enterprise to transmit monitoring images to the monitoring center of the enterprise;

Complete a network-based video surveillance system using fast and appropriate methods and ideas;

The entire system consists of front-end network cameras, local monitoring centers, network clients, central servers, etc.

4、 System composition

1. Front end equipment

This mainly refers to the network cameras installed at various branches, which are responsible for digitally compressing analog signals and converting them into network signals for transmission to the local area network.

2. Network Monitoring Center

The network monitoring center equipment consists of a central management server, a video workstation, an electronic map/alarm host, a television client, and an IP resolution server.

The central management server consists of a PC host installed with system management software. It is the core of the entire distributed network video centralized monitoring and management system. Through the central management server, network cameras, video workstations, electronic maps/alarm hosts, etc. in the system can be configured, including IP address settings, user permission settings, decoder settings, connection channel settings, image quality adjustment, manual and automatic recording settings, etc. Through the central management server, the setting parameters of front-end control devices can be added, deleted, and modified as needed at any time.

The video workstation mainly connects front-end devices such as network video servers and hard disk recorders. The video workstation stores the audio and video signals and alarm signals transmitted by the network video servers, and can backup the video recordings of the hard disk recorders as needed. At the same time, it provides users with the display, recording, and pan tilt control of all remote video images, and also serves as a video source for other network clients, responsible for forwarding audio and video images.

The electronic map/alarm host is an important component of the network video centralized monitoring and management system. Combined with the electronic map, it can accurately reflect the alarm information of monitoring points on the map.

The TV client uses a PC as the video image decoding device and a monitor as the video image display terminal device to display network transmitted video signals. It supports multiple display modes such as multi screen segmentation display, single screen display, and screen rotation switching display.

The IP resolution server is mainly used for address resolution in dynamic IP network environments. For dynamic IP transmission methods such as ADSL, the system's built-in IP resolution server software can be used to solve the problem of network monitoring interruption caused by IP changes. Whether to choose an IP resolution server mainly depends on the network access method. For static IP networks, an IP resolution server is not required. (In this example, whether to use an IP resolution server is determined based on the user's choice of network access method)
