What Is Surveillance Equipment?

A typical TV monitoring system is mainly composed of two parts, the front-end equipment and the back-end equipment. The front-end equipment usually consists of cameras, manual or motorized lenses, gimbals, protective covers, monitors, alarm detectors and multi-function decoders They perform their respective duties and establish corresponding connections (transmitting video / audio signals and control and alarm signals) with various devices in the central control system through wired, wireless or fiber optic transmission media. In an actual TV monitoring system, these front-end devices are not necessarily used at the same time, but the cameras and lenses that realize the monitoring of field image acquisition are essential. Back-end equipment can be further divided into central control equipment and sub-control equipment.

Camera, transmission, control, display four parts

The front and back-end devices have multiple forms of construction, and the connection between them (also known as a transmission system) can be implemented in a variety of ways, such as cable, fiber, or microwave. The TV monitoring system consists of a camera part (and sometimes a microphone), a transmission part, a control part, and a display and recording part. Each part contains more specific equipment or components.

Now, for security prevention, many security monitoring malls and projects use monitoring equipment systems. So, with the development of the monitoring industry in China, what are the advantages of using such a system?

1. Advancedness and inheritance. The construction of the alarm network system of the urban video surveillance project cannot completely abandon the original analog-based system. The appropriate approach is to incorporate the original analog system as much as possible on the premise of planning a fully digital system. The most ideal system is to be able to make a seamless connection between the two to form a complete city video image network monitoring. [1]

2. Performance-price ratio. The designer should reasonably set the system functions, correctly perform the system configuration and equipment selection, and ensure that the overall price of the system is low under the premise that the key equipment is of good grade, so that the system has a high cost performance. The selection of the camera at the front of the system and the level of the back-end software should be the focus of attention. If the number of lines of the front-end camera is less than 460 lines, no matter how good the subsequent system is, it is impossible to ensure the system has a clear image effect. In some applications, advanced features such as wide dynamic range are also required.

3. Convenience of system upgrade and maintenance. Due to the large scale of the system, the system software and core equipment should have automatic upgrade and maintenance functions. In addition, the city monitoring and alarm networking system is composed of multiple complex systems, including network, storage, operating system, platform software, various front-end equipment, etc. Therefore, it is required that each subsystem should have a working log record, including system modules and core equipment.

4. Practicality. The system should take into account local environmental conditions, monitoring objects, monitoring methods, maintenance and investment scale and other factors, which can meet the needs of the normal operation of urban video surveillance alarm networked systems and social public safety management.

5. Reliability and stability. The system should use mature technology and reliable equipment, with backup or redundancy measures for key equipment. The system software has maintenance support capabilities and strong fault tolerance and system recovery capabilities to ensure that the system runs for as long as possible, and can be repaired or restored as soon as possible when the system fails.

6. Scalability. The distributed system and modular structure design should be adopted to meet the needs of system scale expansion, function expansion, and supporting software upgrades. Users can expand or tailor the system at any time as needed to reflect sufficient flexibility.

7. System management function and easy operation. Considering the scale and complexity of the networked system, the management software platform should have a good system architecture, and the core management and business management of the system must be clearly separated to ensure that it meets different application requirements. Due to the large number of management servers, storage and forwarding servers in the system, the network management function of the system must be strong, otherwise daily maintenance cannot be performed; the management and user interface provided by the system must be clear, concise and friendly, and the control should be simple, Flexible, easy to learn and easy to use, easy to manage and maintain.

8. The ability of the system to support secondary development. The number of cameras in a city's surveillance and alarm networking system is at least a few hundred, and many can reach tens of thousands, so the sustainable development of the platform must be considered. To achieve the goal of "video creates value", the system must be qualified for secondary development. Only in this way can the platform's video resources be fully utilized.

9. The degree of system security. System security includes multiple aspects, among which is mainly to prevent illegal users and devices from accessing, so in addition to different levels of authentication methods for different users (including administrators and users), also ensure that illegal devices cannot access Go to the system. Networked monitoring systems are most vulnerable to hackers' attacks, and effective security protection measures should be taken to prevent the system from being illegally accessed, illegally attacked, and infected by viruses. In addition, it is necessary to prevent unsafe factors such as lightning strikes, overloads, power outages, electromagnetic interference and human damage in order to provide comprehensive and effective security measures.

10. Compatibility and standardization. Compatibility is the key to interconnecting devices from many different vendors and protocols. The system should be able to effectively communicate and share data, as far as possible to achieve compatibility and interoperability between devices or systems. The higher the standardization and openness of the system, the longer the life cycle of the system. Control protocols, transmission protocols, interface protocols, video and audio codecs, and video and audio file formats should all comply with the relevant national or industry standards.

Overview of monitoring equipment

Integrated monitoring equipment management

Intelligent integrated monitoring host is a multi-purpose monitoring alarm host developed for important places such as buildings, shopping malls, weak motor rooms, data centers, and so on. It has various functions such as data collection, analysis and processing, linkage control, alarm notification, report query, etc. It has a built-in WEB server. Users can view and monitor the site environment, equipment parameters, alarms, reports and other information through IE browser, instead of manual inspection, to achieve Unattended, improve maintenance efficiency and reduce management costs.

Monitoring equipment features

1. Using low-power embedded industrial control host and embedded configuration monitoring system, the system is fast to deploy, stable and reliable.
