How to choose hd webcam

The use of intelligent high-definition network camera is not limited to security work in public places, and many families tend to choose it when choosing security monitoring tools.But a lot of people to its understanding is limited, do not know how to choose completely, often be fooled by the seller.Today, the surveillance camera manufacturer xiaobian introduces some considerations for buying smart HD network cameras, hoping to help you deepen your understanding of smart HD network cameras.

Buy smart HD network camera the following three aspects we must pay attention to:

1, clear or not, practical is the most important

When buying a smart HD webcam, knowing what you want is the most important thing to do.At present, the general network camera has high imaging ability.Therefore, unless very special monitoring capabilities are required (such as intelligent transportation, financial institutions and other fields), an ordinary intelligent HIGH-DEFINITION network camera is enough to meet the daily needs of security monitoring work.In addition to being wasteful, high imaging configurations do not make monitoring work more convenient.

2, imaging quality, many aspects of consideration

The performance of smart HD network camera must be judged from picture quality.After the purchase of smart HD network camera, we need to pay attention to the camera in different states of clarity (dynamic, static), color restore degree and so on.And whether the quality of the picture remains the same clear and stable when shooting different objects.For the image quality of a surveillance camera, horizontal resolution is only one of the main reference aspects.Wide dynamic, automatic white balance, digital noise reduction, automatic light compensation and so on have a deep impact on the imaging quality of security network camera.In the light and dark transition zone, whether the transition is natural, whether the wide dynamic can be adjusted automatically, whether the observation effect of details under low illumination is clear, and the influence degree of noise, etc.Both largely reflect the quality of high-definition webcams.

3, hd effect, multi-factor casting, the overall solution is the most important

In fact, the monitoring camera manufacturer xiaobian believes that the complex work of intelligent HD network camera in addition to the high-tech investment of the machine itself, supporting auxiliary facilities are also an important reference factor for the quality of imaging.For example, whether the adjustment mode of monitoring camera is perfect, whether the menu function is rich, and the selection of lens in the installation and debugging process will largely determine the clear quality of the picture.In addition, whether the signal transmission line meets the transmission requirements of HD network cameras, and whether the compression and decompression work of terminal transmission devices can be completed in high quality also affect the quality of hd network cameras.
