With the continuous development of science and technology, wireless technology has become more and more advanced. Wireless video surveillance has also been applied to various industries. In choosing a suitable wireless video surveillance system, we must meet the following principles:
1. Practicality. The system should consider factors such as local environmental conditions, monitoring objects, monitoring methods, maintenance and investment scales, and meet the needs of the normal operation of urban video surveillance and alarm networking systems and social and public safety management.
2. Reliability and stability. The system should use mature technologies and reliable equipment, and have 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 as long as possible, and can be repaired or restored as soon as the system fails.
3. Extensibility. Should adopt the distributed system and the modular structure design, in order to meet the system scale expansion, the function expansion, the matching software upgrade demand. Users can expand or tailor the system as needed to provide sufficient flexibility.
4. Advanced and inherited. The construction of urban video surveillance and alarm networking system is impossible to abandon the original simulation-based system. The proper approach is to include the original simulation system as far as possible on the premise of planning a fully digital system. The most ideal system is to be able to seamlessly connect between the two to form a complete city video image network monitoring.
5. Performance and price ratio. The designer should reasonably set the system function, correctly configure the system and select the equipment. Under the premise of good grades of key equipment, the overall price of the system is guaranteed to be low, so that the system has a higher cost performance.
6. System upgrade and maintenance convenience. Due to the large scale of the system, system software and core equipment should have automatic upgrade and maintenance functions. In addition, the city monitoring and alarming networking system is composed of a number of complex systems, including networks, storage, operating systems, platform software, various front-end equipment, etc. Therefore, it is required that each subsystem should have a working log record, including all modules and core equipment of the system.
7. System management functions and ease of operation. Considering the scale and complexity of the networked system, the management software platform should have a good system architecture. The system core management and business management must be clearly separated to ensure that they meet different application requirements. Due to the large number of various management servers, storage and forwarding servers in the system, the network management functions of the system must be powerful. Otherwise, routine maintenance cannot be performed. The management and user interface provided by the system must be clear, concise and friendly, and the operation should be simple and easy. Flexible, easy to learn and use, easy to manage and maintain.
8. The degree of security of the system. System security includes many aspects, among which the main purpose is to prevent the access of illegal users and devices. Therefore, in addition to different levels of authentication methods for different users (including administrators and users), it is also necessary to ensure that illegal devices cannot be accessed. Go to the system.
Networked monitoring systems are most vulnerable to hackers 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 also necessary to prevent unsafe factors such as lightning, overload, power failure, electromagnetic interference, and man-made damage to provide comprehensive and effective security measures.
9. The degree of compatibility and standardization. Compatibility is the key to interconnecting devices from many different manufacturers and protocols. The system should be able to effectively communicate and share data, as far as possible to achieve device or system compatibility and interoperability. The higher the degree of standardization of the system and the better the openness, the longer the life cycle of the system. Control protocols, transmission protocols, interface protocols, video/audio codec, and video/audio file formats, etc., should all comply with the requirements of the corresponding national or industry standards.
Remote Control's wireless video surveillance system has the following characteristics:
1, suitable for long-distance transmission of digital information anti-interference ability, not affected by the transmission line signal attenuation, and can be encrypted transmission, which can be real-time monitoring of the scene thousands of kilometers away. In particular, digital video wireless monitoring can achieve in-person results in the harsh environment of the site or the inconvenience of direct in-depth observation. Even if the scene is damaged, it can still get a real record of the scene in the distance.
2. It is convenient for computer processing. Because the video image is digitized, it can make full use of the rapid processing power of the computer to compress, analyze, store and display it. Through video analysis, abnormal conditions can be detected in time and linked alarms can be achieved, thus realizing unattended operation.
3. The system is easy to manage and maintain The digital video wireless monitoring system is mainly composed of electronic equipment. The degree of integration is high. Wireless video transmission can use wired or wireless channels.
In this way, the entire system is a modular structure, small in size, easy to install, use and maintain.
4, easy to find in the traditional analog wireless monitoring system, when there is a problem, it takes a lot of time to watch the video tape to find the scene records; and in the digital video surveillance system, the use of computer-generated index, in a matter of minutes will be able to find the corresponding On-site records.
