1. Network cameras are too "expensive"
When choosing a surveillance product, when it comes to network cameras, people think that a network camera costs 10,000 to 20,000 yuan, which is too expensive compared to ordinary cameras that can be bought for a thousand dollars.
2. "Technical requirements are too high" for network cameras
When choosing surveillance products, when it comes to network cameras, people will think that the network is too complicated and the technical requirements are too high. In fact, this kind of thinking is wrong. With the rapid development of broadband technology and related technologies, the Internet is entering the home. The intuitive and simple operating system has made it possible for a few-year-old elementary school students to play the Internet. It is almost transparent, or almost no need to care about it.
3. "Poor image quality" of network cameras
Network cameras are based on the network, and the analog local image monitoring system is based on video cables (a few use optical fibers). Although they are all monitoring, these are two completely different system structures. The network camera integrates an ordinary camera and a network converter, and converts the image into a data packet based on the TCP/IP network standard, so that the picture taken by the camera is directly transmitted to the network through the RJ-45 Ethernet interface. The screen can be monitored remotely through the network. The network camera adopts the most advanced camera technology and network technology, and has powerful functions.
Advantages of network cameras
1. Advancement This system uses the existing integrated wiring network to transmit images and conduct real-time monitoring. The system requires less front-end equipment, and the connection multiplication is simple; the back-end only needs a set of software systems.
2. Reliability The main equipment of this system, the network camera adopts an embedded real-time operating system, the required equipment is simple, and the image transmission is realized through an integrated wiring network. The reliability of the system is quite high.
3. The performance and price ratio of the equipment required by the system is extremely simple. The control of the system is all realized by the back-end software system, eliminating a large number of equipment in the traditional analog monitoring system, such as expensive matrices, screen splitters, switchers, and video to network. Because the image is transmitted through the integrated wiring network, a large number of video coaxial cables are omitted, and the cost is reduced.
4. The security system has set up different levels of user authority, and only users with the highest authority can set or change the entire system. Users without permission cannot receive images. The storage of image data is in a proprietary format.
5. The installation and maintenance are extremely simple, and the installation and use of the software system are also very easy to understand. In terms of maintainability, the wiring of the system is very simple, and the reliability of the main equipment is high, the maintenance performance is good, and remote maintenance can be achieved.
6. Expansion and extensibility When it is necessary to increase monitoring points and monitoring hosts, it is only necessary to add a camera or PC through the existing network, without any changes to the existing wiring system.
7. Wide application scope and regional monitoring: use the network to transmit real-time images, such as cross-regional remote monitoring of offices and buildings; chain businesses, large-scale factory computer rooms, remote elderly and child care, public buildings, unmanned hazardous environment monitoring, etc. Financial institution branch monitoring, traffic supervision, false alarm identification department, etc.
