Second, the image quality, in many ways to consider the performance of high-definition cameras, certainly still have to judge from the picture quality. If you are sure you need a high-definition camera to meet your work needs. Then in the selection process, you need to pay attention to the camera's clarity (dynamic, static), color reproduction, etc. in different states. There is also the ability to maintain the same clarity and stability in the picture quality when shooting different objects. Horizontal definition is only one of the major reference aspects for the imaging quality of a surveillance camera. Wide dynamics, automatic white balance, digital noise reduction, automatic metering compensation, etc. all have a profound effect on the imaging quality of security cameras. Whether the transition in the bright and dark transition area is natural, whether the wide dynamics can be automatically adjusted, whether the detail observation effect under low illumination is clear, and the degree of influence of noise and so on. To a large extent, they all reflect the level of high-definition cameras.
3. High-definition effects, multi-factor casting In fact, in addition to the high-tech input of the high-definition camera itself, the supporting facilities are also important reference factors for the quality of the image. For example, whether the monitoring camera's adjustment mode is perfect, whether the menu function is rich, and the lens selection during the installation and debugging process, will determine the clear quality of the picture to a large extent. In addition, whether the transmission line of the signal satisfies the transmission requirements of the high-definition camera, and whether the compression and decompression of the terminal transmission device can be completed with high quality also affects the work quality of the high-definition camera.
I. Clarity or not, practicality is the most important When we choose a high-definition camera, clarifying our own needs is the most important preparation. At present, the average video camera already has a very high imaging capability. Therefore, unless there is a need for extremely special monitoring capabilities (such as intelligent transportation, financial institutions, etc.), an ordinary surveillance camera is enough to meet the daily needs of security monitoring. Excessive imaging configuration not only causes waste, but also does not bring more convenience to the monitoring work.
