What are the mistakes in choosing a network camera?
Network cameras (webcam servers, video servers, network video converters, etc.) are entering actual engineering.
Eliminate the misunderstanding of understanding, recognize the characteristics of the network camera can accelerate the popularization of practical applications.
Questions raised:
When selecting digital networked multimedia surveillance products, due to subjective and objective factors, various doubts have arisen, which have been difficult to be widely promoted and applied in the past few years. Stepping into the 21st century, with the development and promotion of the information revolution, with the popularization of broadband networks, people's consciousness has undergone corresponding changes, but there are still many misunderstandings in understanding, hindering the development of monitoring to digital and networked. pace of.
too expensive
When choosing a surveillance product, when it comes to a network camera, people will think that the network camera will cost one or two thousand yuan, which is too expensive compared to the ordinary camera that is bought for a thousand dollars.
First of all, the network cameras produced in foreign countries in the early stage do need one or two thousand yuan, but the prices of a number of domestic manufacturers have been reduced to several thousand, which has greatly reduced the price of the products. Secondly, a W74GM network camera is equal to the computer + video capture card + CCD ordinary camera + network card + operating system + software, that is, on the monitoring side, only one network camera can be used to send the video to the network. Therefore, it is not appropriate to take a normal camera and a webcam at a price.
Technical requirements are too high
The network is basically based on TCP/IP. Although the network itself has many protocols, the network equipment (including the network camera) itself is technically complicated. However, due to the unified network protocol, the products of all manufacturers have been able to do basic operations such as boot/shutdown, arming/disarming, etc. All are handed over to the network products, the real automatic fool-type operation, there is no need to intervene too much.
Poor image quality
The network camera is based on the network, simulating local images, and the monitoring system is based on video cables (a few use of fiber optics), although both are monitored, which are two completely different system structures. In the case that the transmission distance is not too far, the monitoring point is not much, and there is no need for remote transmission, the user is recommended to use an analog image monitoring system.
