How can the engineer choose the right network surveillance camera?
How do engineers choose the right network surveillance camera?
First point, the software and hardware functions of the camera
In general, network camera manufacturers face the diversified needs of market users, hardware, not only to meet the basic remote monitoring of motion detection alarm input and output and other common functional requirements users; also meet the special needs of zoom license plates and other special functions Users to meet the needs of various application environments. In terms of software, it should have a user-friendly setting management operation platform, which is convenient and easy to use and easy to operate. Choose a suitable camera according to the usage environment. For example, you cannot select an indoor unit for outdoor use, and you cannot use a telephoto lens for large scenes.
The second point of actual application effects and configuration
In order to facilitate customers to understand the performance of their products, HD network camera manufacturers generally provide services such as online demonstration or monitoring video file downloading. Customers can watch the actual application effects by playing video, and conduct a preliminary understanding, and then the HD network camera itself. An important number of accessories, such as the sensor chip infrared lamp lens filter switching device, can be consulted to gain an in-depth understanding of the product’s performance. Generally, high-quality high-definition network cameras use high-pixel sensor chips and high-quality infrared lamps. The lenses use high-end lenses of 2 million or 3 million pixels, and are equipped with automatic filter switching devices to improve the monitoring performance of network cameras.
Third point Compatibility performance
Previously, most HD network camera manufacturers were fighting each other and did not form a unified standard, which led to the incompatibility of front-end and back-end products of different manufacturers, which largely prevented the promotion of high-definition network monitoring systems. Nowadays, major manufacturers and users have realized the shortcomings of this problem. Various manufacturers in the industry are actively participating in and intensifying the development of interface standards for high-definition network monitoring systems, and satisfying the compatibility of users with more products through secondary development. At present, the most widely used HD network monitoring system is the ONVIF-compatible protocol, and it is expected to become the platform standard for unified management of domestic network cameras. Therefore, the high-definition network cameras provided by the manufacturers should be able to support the latest version of the ONVIF protocol, which is compatible with the use of more products and unified management, to achieve interconnection and data sharing.
Fourth point Back-end solutions and product services
A complete high-definition network monitoring system includes technical applications such as front-end video equipment network transmission back-end storage display control decoding and large-scale platform management on the wall. The solution for providing overall application is an important criterion for measuring a high-definition network monitoring product supplier. . This requires suppliers to have the corresponding technical strength and have a total system solution.
