With more and more high-definition surveillance in people's field of vision, as well as the development of civil security market, more and more high-definition network cameras into the list of people purchasing products, then what are the considerations for the purchase of high-definition network cameras?
To understand the strength of suppliers
Users need to understand the strength of HD network camera vendors. At present, domestic manufacturers are confusing. Because the threshold for entry into the industry of manufacturers is relatively low, the quality of products produced varies greatly, and some manufacturers cannot therefore continue to develop in the market for a long time. The inconvenience caused by the after-sales service, many users are reflected in the HD network camera failure, often even the manufacturers can not find. Therefore, before buying, you must have enough knowledge of the manufacturers.
Find the right network video surveillance equipment
In the former market, HD network cameras have gun-type, ball-type, hemispherical, and hemispherical hemispheres. According to the requirements for installing lines, they can be divided into wired network cameras and 3G network cameras and WIFI network cameras. According to the different needs of the user to choose, should choose a cost-effective, with extended performance products.
Does the vendor provide back-end equipment
With R & D strength manufacturers, back-end equipment is usually done by R & D team, standard products to meet the needs of most customers. For the individual needs of some large customers, manufacturers with R&D strength can use the R&D team to improve the standard, to realize the customization requirements of large customers and provide customers with products that meet the performance requirements.
See the manufacturer's service projects within <br> <br> industry, with differences in each grade manufacturers of high-definition network camera is not large, who can provide customers with more comprehensive services, who will be able to capture the market. Before the purchase, the user can often communicate with the manufacturer's technology to fully understand the project of the network camera manufacturer after-sales service. It should be noted that for the manufacturer's warranty program must be in-depth understanding, to avoid the maintenance costs are too high due to problems in the later period.
Network cameras (webcam servers, video servers, network video converters, etc.) are entering the actual project. Eliminating misunderstandings in understanding and understanding the characteristics of network cameras can speed up the popularization of practical applications.
One, network cameras are too expensive
When choosing a monitoring product, when one mentions a network camera, one would think that a network camera would cost one or two million yuan, which is too expensive compared to an ordinary camera that is bought for a thousand dollars.
First of all, the IP cameras that were produced in foreign countries do need 12-20 thousand yuan, but the price of a group of domestic manufacturers' products has been reduced to a few thousand or so, which has greatly reduced the price of the products.
Second, a W74GM network camera = computer + video capture card + CCD ordinary camera + network card + operating system + software, that is, on the monitor side, only need a network camera to send the video to the network. Therefore, it is not appropriate to use ordinary cameras and webcams as prices.
Second, the network camera "technical requirements are too high"
When choosing a monitoring product, people will think that the network is too complicated and the technical requirements are too high. In fact, this is a kind of fear. The Internet is going into the home. The teenagers have turned the internet around. The network is almost transparent to the project traders and users, or almost no need to control him.
At present, networks are basically based on TCP/IP. Although there are many protocols in the network itself, the network equipment (including the network camera) itself is complicated, but due to the unified network protocol, the products of all manufacturers can do as long as they know the start/shutdown, arm/disarm and other basic operations. All of this is done by network products. The true automatic fool-type operation requires no intervention at all.
Third, the network camera "image quality is poor"
The network camera is based on the network, simulates the local image, and the monitoring system is based on video cables (a few use fiber optics). Although they are all monitored, these are two completely different system structures.
According to the opinion of the network camera manufacturer, "We emphasize that network cameras are not universal, because the network itself is not universal. We still recommend users to use analog images in situations where the transmission distance is not too far, there are not many monitoring points, and there is no need for remote transmission. surveillance system."
