Clear or not, practical and 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 you need very special monitoring capabilities (such as intelligent transportation, financial institutions and other fields), an ordinary camera is enough to meet the daily needs of security monitoring work. Excessive imaging configuration not only causes waste, but also does not bring more convenience to the monitoring work.
Image quality, many considerations
The performance of high-definition cameras must be judged 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 clarity of the camera in different conditions (dynamic, static), color reproduction and so on. 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 camera. Wide dynamics, automatic white balance, digital noise reduction, automatic metering compensation, etc. all have a profound effect on the imaging quality of the camera. 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.
HD effects, multi-factor casting
In fact, in addition to the high-tech input of the machine itself, the supporting work of the HD camera is also an important reference factor for the quality of the image. For example, whether the 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 meets the transmission requirements of the high-definition camera, whether the compression and decompression of the terminal transmission device can be completed with high quality, and it also affects the work quality of the high-definition camera.
Therefore, the realization of high-definition effects must not only be accomplished by a simple camera itself, but also be cast by the camera, the surrounding environment, and supporting equipment. Therefore, before selecting high-definition cameras, in addition to the camera itself, there will be more attention to the environment, I am afraid you will gain more than expected.
At present, with the increasing reliance on security cameras for surveillance cameras, the clarity of cameras is also expected to be higher and higher. It seems that HD has become a fashion for people to choose and use surveillance cameras. It is also based on this that the market for high-definition video cameras is now developing extremely hot. As new types of new products and technologies emerge in an endless stream, it seems that manufacturers are trying their best to meet the different needs of users. However, for us, what kind of product is best for us? Can the current camera be as clear as possible under what circumstances? In the following, we will help you solve the confusion when choosing a camera through the following three aspects.
