Compared with traditional monitoring, high-definition monitoring has clearer picture quality and a wider radiation range. In recent years, with the widespread application and popularization of high-definition monitoring projects and engineering in safe cities and road monitoring fields around the world, reports of police using high-definition monitoring to solve cases and arrest criminals have emerged one after another, which is not uncommon.
Record the truth, trace the source, punish evil and promote good. It cannot be denied that security surveillance has entered our lives and we have been influenced by it. With the increasing popularity and promotion of high-definition surveillance products, we believe that high-definition surveillance will create a safer and better life for people, and China will enter a harmonious society earlier.
Three key points for purchasing high-definition network cameras:
1. Whether it is clear or not, practicality is the most important
When choosing a high-definition camera, being clear about our own needs is the most important preparation work. Currently, most cameras have high imaging capabilities. Therefore, unless extremely special monitoring capabilities are required (such as in the fields of intelligent transportation, financial institutions, etc.), a regular high-definition network camera is already sufficient to meet the daily needs of security monitoring work. Excessive imaging configuration not only causes waste, but also does not bring more convenience to monitoring work.
2. Imaging quality, considering multiple aspects
The performance of high-definition cameras must be evaluated based on the picture quality. If you are certain that you need a high-definition camera to meet your work requirements. So in the selection process, it is necessary to pay attention to the clarity (dynamic, static) and color reproduction of the camera in different states. Another question is whether the image quality can still maintain the same clarity and stability when shooting different objects. For the imaging quality of a surveillance camera, horizontal clarity is only one of the main reference aspects. Wide dynamic range, automatic white balance, digital noise reduction, automatic metering compensation, and so on all have a profound impact on the imaging quality of security cameras. Whether the transition between brightness and darkness is natural, whether the wide dynamic range can be automatically adjusted, whether the observation effect of details under low light is clear, and the degree of noise impact, etc. All of them largely reflect the level of high-definition cameras.
3. High definition effect, multi factor casting, overall solution is the most important
In fact, the complexity of high-definition camera work is not only due to the high-tech investment of the machine itself, but also an important reference factor for the quality of imaging with supporting auxiliary facilities. For example, whether the adjustment method of the surveillance camera is complete, whether the menu functions are rich, and the selection of lenses during installation and debugging will largely determine the clarity and quality of the image. In addition, whether the signal transmission line meets the transmission requirements of high-definition cameras and whether the compression and decompression work of the terminal transmission device can be completed with high quality also affect the quality of high-definition camera operation.
So, the implementation of high-definition surveillance effects does not only require a simple high-definition network camera itself, but is also forged by multiple factors such as security cameras, surrounding environment, and supporting equipment. Therefore, before choosing a high-definition camera, in addition to the surveillance camera itself, paying more attention to the environment may yield more than expected.
