What Is a Network Camera?

A network camera is a new generation of camera produced by combining traditional cameras and network technology. It can transmit images to the other side of the earth through the network, and remote viewers do not need any professional software, as long as a standard web browser ( Such as "Microsoft IE or Netscape" can monitor its image. Network cameras generally consist of lens, image, sound sensor, A / D converter, image, sound, controller network server, external alarm, control interface and other parts.

With the rapid development of the Internet, network products gradually cover every corner of our lives. The development and innovation of network cameras are widely used in many fields, such as education, commerce, medical care, public utilities, etc.

Ordinary audio and video camera surveillance systems used in banks, supermarkets, companies, and even some homes are gradually being replaced by network cameras, and all recorded content will be directly transmitted online. You can sit at home or anywhere you can access the Internet through the Internet and see real-time updated photos or movies provided by public or private.
The self-care ability of the elderly and children is generally poor. If there is no special person in attendance, it is easy to be dangerous, which makes it difficult for family members to worry, especially in kindergartens, elderly homes and other places. Network cameras are installed in these places, and the supervisory managers can keep abreast of their activities, and their families can also learn the current situation of their families through the network cameras at home, so that parents can work at ease.
With the development of social economy, there are more and more group companies, and the business activities between various branches are more frequent. As a corporate leadership, it is often necessary to travel around the various subsidiaries and participate in various business activities. Network cameras can be used to remotely and intuitively grasp the situation of companies and factories through the network. Due to the influence of the external environment, the network camera appears suitable for indoor. Outdoor network cameras use a professional CCD sensor chip, a hemisphere protective cover, waterproof and high temperature, inhibit strong light, infrared night vision; can adapt to more severe Outdoor environment that supports wireless routing.

When Axis started the CD-Rom business in 1995, Martin Glenn's accidental customer meeting brought a historic turn to Axis' development and gave birth to the idea of developing a network video surveillance system product. Martin Glen was on a business trip in Japan and met a client who was very interested in the business. At the same time, he also learned from the history of Axis that Axis is a company focusing on providing network services. This customer is a large Japanese conglomerate with a large inventory of unsaleable analog cameras, and they asked Axis if they could network these cameras to improve their performance. Martin Glen saw new market opportunities from customer needs, and returned to the company to begin the study.

During the research process, Martin Glen realized that this is a market completely occupied by analog cameras. With the development of network technology, analog cameras have become increasingly unable to meet the growing demand for network video development. Digital technology will revolutionize the field of video surveillance. At that time, Martin Glenn said to himself, "Sooner or later, all analog technology will be replaced by digital technology."
Based on this market insight, Martin Glen led the Axis team to do a lot of market research. Through research, Martin Glenn keenly observed that during the dot-com bubble era, the Internet became mainstream and the market was destined to go digital with the entire society. Through unremitting efforts, Axis demonstrated the world's first network camera for the first time at the Networld + Interop exhibition in Atlanta on September 18, 1996.

Because of its excellent product, the product quickly gained widespread attention and won multiple innovation awards. At that time, Axis focused on remote monitoring applications, and the transmission time was almost the same as the time that the camera provided the image. In the first few years, about 50% of Axis' products were sold to professional remote monitoring applications, and the rest were supplied to various "network attraction" applications on the Internet. At this point, Axis has begun to make the network more intelligent and promote the market's transition from analog to digital technology. Axis has successfully developed a new market.

1. As the most representative third-generation networked video surveillance product, network cameras have been widely recognized by the market in the field of industrial security protection. More and more security projects use network camera products for implementation.

With the development of the overall society and economy in China, network cameras have begun to enter ordinary people's homes. In small shops, offices and homes, the Internet can already be seen.

In general security monitoring system installation, the installation and debugging methods of HD network cameras and ordinary cameras are basically the same, but you must pay attention to the selection of the lens, because the quality of the lens is not good, or the selection is not good, it will largely Affect the sharpness of the picture;

For example, the infrared night vision system camera is best to use an infrared lens, while the 1 / 3-inch CCD is usually equipped with a 1 / 3-inch lens, and the 1 / 2-inch CCD is usually equipped with a 1 / 2-inch lens. It must be adjusted, especially the back focal plane of the camera must be adjusted. In many cases, the focus of the lens is unclear, which will cause the image to be blurred, which cannot meet the requirements of high definition.

In addition, the protective cover of the camera can not be ignored. The front glass of the gun-type protective cover cannot use general flat glass, but must use better optical glass. General flat glass has a very strong weakening effect on the resolution of the image. The spherical shell should pay more attention to the curvature of the spherical surface must be smooth, it is best not to point the lens at the upper edge of the spherical shell, where the light's refractive power is large, and it can even seriously affect the sharpness of the image. It is very important that no matter what kind of cover, it is better to lower the light in the cover, the better, and the shorter the distance from the lens to the cover, the better the light pollution in front of the lens will be reduced, which will help improve the image Clarity.

The 3G IP Camera adopts the latest 3G mobile communication technology, and is designed to implement a simple, convenient, and cost-effective device for home, small business, or users in specific industries.

With the application of large-scale security systems in various public places, the demand for the prevention of terrorist attacks and public security through intelligent video surveillance systems is increasing. Intelligent video based on central processing

1. Unable to access the external network. At this time, you should first determine whether you have changed the IP or WEB after getting the machine.

One of the first factors when purchasing a network camera is to look at the quality, but not stick to the product specifications . The quality of the IP camera is not just the numbers listed in the product specification table. The initial appeal of network cameras came from superior image quality, but network cameras are constantly evolving and image quality is now only one of its outstanding features.

Users should also calculate the total cost of ownership (TCO) of the network camera solution, which is greatly affected by the cost of image storage.

Network video cameras are much more than just an authentication tool . Equipped with more intelligent technology, network cameras have now become an important part of the active intelligence chain. ^[1]

1. Choose the location where you want to install the camera. This needs to be selected according to the needs of the scene and the situation. Others can't help you. Take out the surveillance camera bracket, prepare tools and parts: necessary tools such as plugs, screws, screwdrivers, hammers, electric drills, etc .; check the size and model of the plugs and self-tapping screws according to the predetermined installation position, and try the bracket Check whether the screw and the screw port of the camera base are suitable, whether the pre-buried pipeline interface is properly handled, test whether the cable is unblocked, and enter the installation program when ready. The installation height should meet the requirements of the field of view of the monitoring target: the indoor ground clearance should not be lower than 2.5m; the outdoor ground clearance should not be lower than 3.5m.
