Video Conference

Nowadays, in commercial services, the high-definition video conference method that reduces the distance between the corporate headquarters base and each branch is highly praised, and the conference camera can be said to be a first-class father. So if you want to do a good job in a video conference, how to choose a high-definition video conference camera correctly?

With the wider application of video conferences, the company has gradually increased the regulations on video conferences, and the technical improvement of machinery and equipment has also led to more and more high-definition video conference equipment, especially as the key machinery and equipment. The key points of the selection of high-definition video conferencing cameras depend on the following three aspects:

Interface screen resolution

Whether the screen resolution of the interface that can be captured by the surveillance camera is high-definition is the first key point in purchasing a surveillance camera. At this stage, real high-definition video generally refers to video with 1080i and 720P screen resolution. The video screen resolutions below 720P, such as 480i, 576i, etc., are all plain. So where is the key reflection of my high-definition and general-definition?

The visual effect experience of both eyes is the dominant factor, and the 4k and 720P interface will look very detailed and the picture quality is very good. The actual effect of the borders such as the character scenery in the video below 720P will look a little blurry. Therefore, if you want to choose a high-definition video conference camera, it is best to choose a video screen resolution of 720P or above.

Optical lens

As far as how to choose a high-definition video conference camera, the characteristics of the optical lens are also one of the important indicators of the surveillance camera. At this stage, there are two types of CCD and CMOS in the sales market. To put it simply, the cost and functional loss of CMOS products are relatively low.

This is why many products using a USB interface do not need an external switching power supply, but CCD has excellent image quality. At this stage, the specifications of CCD components are generally 1/3 inch or 1/4 inch. Under the same screen resolution, it is better to choose higher component specifications.

Delivery broadband network

At this stage, high-definition is the popular development trend in video conference marketing and promotion. However, it must be noted that to achieve the actual effect of high-definition, the overall high-definition equipment must cooperate, but the actual terminal equipment equipped with high-definition surveillance cameras and high-definition is insufficient, and server bandwidth is also one of the key elements.

Therefore, customers should consider the working ability of their network bandwidth when purchasing HD. If the network bandwidth cannot be used for high-definition broadcast, the packet loss rate will occur, which will endanger the actual effect of the conference. Puking or high-definition should be used according to practical, do not blindly follow the trend to pursue the perfect fashion trend
