USB cameras are often the first choice for video conferencing. Simply connect USB to your computer launch Zoom, Google Meet or Microsoft Teams, and the meeting can begin. But it’s not just USB cameras that can be used for conferencing. In fact, sometimes, the alternatives may be the better solution.
Generally speaking, USB conference cameras are suitable for personal and small conference rooms. Large conference rooms, lecture halls or hybrid classrooms may suit alternative types of camera.
|Types of Cameras||Required Interface||Application Scenarios|
|Video Conference Camera||USB||Personal or small meeting room|
|PTZ Camera||HDMI , SDI / Network||Classroom or large meeting room|
|Auto Tracking Camera||HDMI , SDI / Network||Classroom or large meeting room|
|Professional Camcorder||SDI||Professional video studio|
|Surveillance Camera||Network||Remote security and surveillance.|
Zoom, Google Meet and Microsoft Teams partner easily with USB cameras. Unfortunately, most USB cameras rely on fixed lenses and are optimized to shoot from 1-2m distance. They also lack robotic mechanisms that are useful to frame the perfect shot. Many professional video cameras are equipped with Ethernet, SDI and HDMI connectors, requiring USB Converter devices to be added as a video conferencing accessory. An HDMI to USB adapter works well, but is costly and limited by the length of the USB and HDMI cables.
