The Misunderstanding Of Network Camera

1. Webcam is too "expensive"

When selecting monitoring products, people will think that when they mention the network camera, it costs 10000 or 20000 yuan, which is too expensive compared with the ordinary camera bought at a cost of thousands of yuan.

2. Webcam "technical requirements are too high"

When choosing monitoring products, people will think that the network is too complex and the technical requirements are too high when it comes to network cameras. In fact, this idea is wrong. With the rapid development of broadband technology and related technologies, the network is coming into the family. The intuitive and simple operating system makes several year old primary school students play the network well. The network is almost transparent to engineers and users, or there is almost no need to care about them. At present, the network is basically based on tcp/ip.

3. Webcam "poor image quality"

The network camera is based on the network, and the analog local image monitoring system is based on the video cable (a few use optical fiber). Although both are monitoring, these are two completely different system structures. The network camera integrates an ordinary camera and a network converter to convert images into data packets based on tcp/ip network standards, so that the pictures taken by the camera can be directly transmitted to the network through RJ-45 Ethernet interface. You can remotely monitor the screen through the network. The network camera adopts the most advanced camera technology and network technology, and has powerful functions.

Advantages of webcam

1. Progressiveness the system uses the existing generic cabling network to transmit images and conduct real-time monitoring. The front-end equipment required by the system is few, and the connection multiplication is simplified; Only one software system is required at the back end.

2. Reliability the network camera, the main equipment of this system, adopts an embedded real-time operating system. The required equipment is simple, and the image transmission is realized through the generic cabling network. The reliability of the system is quite high.

3. The equipment required by the performance price ratio system is extremely simple. The control of the system is fully realized by the back-end software system, which saves a large number of equipment in the traditional analog monitoring system, such as expensive matrix, picture splitter, switcher, host of video to network, etc. because the image is transmitted through the generic cabling network, a large number of video coaxial cables are saved and the cost is reduced.

4. The security system sets different levels of user permissions. Only users with the most advanced permissions can set or change the entire system. Users without permission cannot receive images. Image data is stored in a proprietary format.

5. The installation for use and maintenance is 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 main equipment has high reliability, good maintenance performance, and can realize remote maintenance.

6. Expansion and extensibility when it is necessary to add monitoring points and monitor the host, it is only necessary to add a camera or PC through the existing network without any change to the existing cabling system.

7. Wide application range regional monitoring: use the network to transmit real-time images, such as cross regional remote monitoring of offices and buildings; Chain business, large factory machine room, remote elderly and children care, public buildings, unmanned hazardous environment monitoring, branch monitoring of financial institutions, traffic supervision, error alarm identification department, etc
