Background Introduction

Currently, only some small enterprises have built their video surveillance systems, and the video surveillance systems they use are mostly early analog (CCTV) or digital (DVR) surveillance. The video clarity is insufficient, the performance and stability are not high, and it is difficult to maintain. If the distance between different departments is far, and a dedicated video line from the monitoring center to the factory area is laid, the amount of wiring work will be huge, which will greatly increase the cost of the entire project. With the development of network and computer technology, the application of IP networks based on TCP/IP protocol has been widely popularized. The construction of high-speed broadband backbone networks and the rapid development of high-speed access systems in various regions have promoted the development of various video communication applications based on IP technology. Therefore, introducing high-definition network video monitoring systems into security monitoring systems for small businesses has become a trend.

The Kuer Network Camera Video Monitoring System is a high-definition video monitoring system based on the TCP/IP protocol. PFEIFFER EVR116 utilizes the Kuhl network camera video monitoring system, allowing central monitoring personnel to directly monitor the entire production process of the enterprise in real-time. It can intuitively monitor and record the safety production situation at the workshop workplace, detect potential accidents in a timely manner, prevent accidents in advance, and provide relevant first-hand image data for post accident analysis, providing reliable guarantees for future safety production.

summary

The establishment and continuous improvement of security systems have played an important role in protecting personnel and equipment safety, improving production and management efficiency, preventing and stopping crime, and maintaining social and economic stability.

System Introduction

Zhongshan Huayi Lighting Factory has set up a total of 38 monitoring points, distributed at the entrance, several workshops, and office spaces. This system solution consists of two parts: front-end equipment and control center. 35 front-end devices, servers in the control center, clients, decoder devices, etc. are connected through an IP network to form this system.

Zhongshan Huayi Lighting Factory has installed a simulation monitoring system. Due to unclear images in the simulation monitoring system and the consideration of adding new monitoring points, the cost of laying a lot of video cables will be high. Therefore, the factory has decided to adopt a network video monitoring system. The newly added 15 fixed monitoring points use high-definition network infrared cameras installed at the entrances of various production workshops and warehouses in the company, ensuring that on-site images can be monitored all day long; Add a network smart ball camera in the main production workshop, which can clearly see all the details of production in the workshop by rotating the pan tilt and controlling the extension and contraction of the lens; In the factory warehouse, a high-definition network hemispherical camera with a 15 meter infrared irradiation function has been installed. Even in an environment where the lights are not turned on at night, the management personnel can control the pan tilt rotation to have a clear view of the entire warehouse; The original analog camera was upgraded to a network video monitoring system by using a standard definition network video server to digitize and compress on-site video information. These network infrared integrated cameras and network video servers do not require specialized wiring and are directly connected to the secondary switches near their location, connected to the factory’s network center. The switches in the system control room are also connected to the network center. Audio and video images are compressed and encoded in real-time by network video equipment and transmitted through the IP network. A network video decoder has been installed in the guard and security departments, which outputs the video from the decoder to the TV. The guard and security personnel can see the images of their respective locations on the TV screen (old CCD cameras). The front-end equipment mainly adopts the company’s network infrared integrated camera KE-PN1304/F10 and network video server KE200 series products. In addition to having high-definition image compression and network conversion functions, video devices can also be connected to alarm devices such as infrared targeting devices.

The main control room is equipped with three system servers for equipment management, user management, control management, video management, etc. of the entire monitoring system; Configure several PC computers as system clients according to actual needs.

The computer network of the factory is connected to the Internet through a router, and the factory leaders can realize real-time visual monitoring of the main departments of the factory by logging on to the Internet.

1. Monitoring front-end components

The monitoring front-end mainly consists of network infrared integrated cameras and network video servers as the core. The video monitoring system achieves real-time image monitoring of various departments in the factory through existing computer networks. The following devices are recommended for the front-end section:

A. Network infrared camera;

B. Fixed lens for network cameras (KE-PN1304/F10 series);

C. Fixed lens of network hemisphere camera, 355 ° rotation, low-speed pan tilt with decoder, and 10-20 meter infrared night vision equipment;

E. The best product for upgrading and upgrading network video servers and analog video monitoring systems.

2. Transmission network and backend parts

The system control room is the central hub of this system, responsible for all front-end equipment management, control, alarm processing, recording, video playback, user management, and other work in this system. A total of 3 servers need to be configured in the control room (it is recommended to use an i5 processor, independent graphics card, 1000M network card, 2GB memory), and the hard disk configuration of the servers depends on the actual recording needs. The server required to be configured in the control room can integrate display and recording. Each image monitoring server can simultaneously display images of 16 front-end devices. The server is connected to the backbone switch in the center, while other devices are connected to the secondary switch in the control room.

The image monitoring server needs to be pre installed with Windows XP operating system (SP2 patch) or WIN7, and installed with Kull’s multi screen monitoring software and video server software, responsible for storing all relevant databases of the system.

A network video decoder has been installed in the guard and security departments, which outputs the video from the decoder to the TV. The guard and security personnel can see the images of their respective old surveillance cameras on the TV screen. By using the unique virtual matrix function of the Kuhl network video decoder, the front-end 14 channels of videos can be switched to 2 display devices, and all video images can be observed. By connecting to the keyboard of the network video decoder, the video images can be manually switched, and the pan tilt and lens zoom can be controlled.

All video signals are processed and converted into TCP/IP based packets, allowing the images captured by the camera to be directly transmitted to the network through the RJ-45 Ethernet interface, and the images can be remotely monitored through the network. The staff can grasp the situation of each monitoring point through this system, and have a panoramic view of everything that happens in the monitored area. System operators can observe all video images on the computer by operating the system, and can simultaneously zoom in on the video images or record video images of each monitoring point.

The system adopts advanced digital processing technology, which can replay previous data without affecting normal recording, ensuring the integrity of the data. The system can freely control the speed of video playback when replaying previous data, allowing for fast, normal, and slow playback.

The system adopts standard TCP/IP network protocol transmission and supports application protocols such as SMTP, FTP, DHCPClient, TCP/IP, UDP, DDNS, etc. It is widely applicable to LAN, WAN, Internet, wireless network (WLAN, microwave, wireless spread spectrum), etc. Users can share system resources through authorization.
