The universal definition of the concept of HD is the most important indicator for the inspection of surveillance cameras. Surveillance camera, see clearly, is king. Traditional analog cameras, because they transmit analog signals, can only reach a maximum of 400,000 pixels in resolution, which is far from the current security requirements. It is impossible to clearly see the target state during monitoring, and it is even more difficult to use intelligent software. This is where it has not been able to match the network camera.
On the signal transmission, the network surveillance cameras gradually came up. When the network cameras were first introduced, the problem of transmitting signals has been criticized by people. With the popularity of the Internet, paving the way for network cameras' information transmission. In any place where there is a network, you can effectively monitor through the network. This is the height that analog surveillance cameras can never reach.
In terms of cost, the network camera is more cost-effective. Currently, the cost of the network camera is higher than that of the analog camera. This is an indisputable fact, but it should also be seen that its function is unmatched by the analog camera. According to statistics: if the IP infrastructure If it is already installed, the cost of an online video system is always low. The total cost of ownership of network video systems with 40 or more cameras is lower than that of analog systems. For IP systems and analog systems, 32 cameras are their balance points. In general, if more than 32 cameras are used, the cost of the network video system will be lower.
In general, compared with analog cameras, network cameras eliminate the cost of wiring, and in general, the cost is basically the same as analog surveillance cameras, even less than its cost.
Summarizing the Internet age, the Internet, the Internet of Things, and the world are all connected. As a product that keeps pace with the times, network surveillance cameras will certainly take the place of analog cameras in the future, and will become an unassailable leader in the security industry.
In the field of security industry, it has always been the surveillance camera. Since the opening of the remote monitoring era, analog surveillance cameras have always dominated the industry. But now with the advent of the Internet era, HD has gradually become the goal of people chasing. Then, in the next few years, how does the network surveillance camera surpass the traditional analog surveillance camera and become the dominant player in the industry? The author analyzes from the following points.
