The use of video conferencing is becoming more and more common, and cameras have a key effect in video conferencing, which is a hardware configuration machine that cannot be ignored. So, how to choose a video conference surveillance camera?
Generally speaking, which cameras are selected depends on the actual application situation. For example, do you need to capture the entire main venue during a video conference? Do you need to track the spokesperson? What is the total area of the conference hall? Need to carry out lifting? This basic requirement is clear and then compares the price, appearance, technical parameters, and so on. Surveillance cameras can also be referenced from the following main parameters.
01
Lens The camera lens is the key component of the camera, and the sensor of the camera can be divided into CCD and CMOS. CCD is a high-end technical component used in professional photography. CMOS is used in products with lower image quality. Its advantage is that the manufacturing cost is lower than that of CCD, and the functional loss is much lower. The product does not need an external power supply. At this stage, the specifications of CCD components are mostly 1/3 inch or 1/4 inch. Under the same resolution, it is better to select components with large specifications.
02
The pixel sharpness value is a key indicator value that endangers the quality of the camera, and it is also a key indicator for distinguishing whether it is good or bad. Nowadays, the definition value of main products is generally around 2 million. Blindly considering the clarity value is also redundant. Because the higher the definition value of the product, the stronger the ability to analyze the image, in that case, when the camera is working, the computer's ability to carry out data processing methods are also required to be higher, otherwise it will cause the delay time of the picture. , thereby jeopardizing the transmission of the video conference.
03
Resolution Resolution is the ability of surveillance cameras to analyze and identify images. Naturally, it is directly related to the pros and cons of CCD/CMOS. Generally, it can be divided into two types of camera resolution and video resolution, that is, the resolution of static data image capture and the resolution of dynamic image capture. In the specific application of video conferencing, the resolution of the camera is generally higher than that of the video. At present, the types of resolutions that can be obtained by surveillance cameras on the market are not the same, so you should pay attention when you are buying them. Compared with the hardware configuration resolution or has a certain difference.
