Differences and Advantages of USB2.0 and USB3.0 Camera Modules
Transmission rate:
USB2.0 camera module: the theoretical transmission rate is 480Mbps, i.e. 60MB/s. In practice, the actual transmission rate may be lower due to various factors. This transmission rate can basically satisfy the general SD video transmission or the scenarios that do not require high picture quality and frame rate, but if you need to transmit HD video, a large amount of image data or real-time video streaming, the bandwidth of USB2.0 may become a bottleneck.
USB3.0 Camera Module: The theoretical transmission rate is up to 5Gbps, i.e. 625MB/s, which is more than 10 times of USB2.0. It can easily cope with the transmission needs of high-definition video, and even high-resolution and high-frame-rate video streams can be transmitted smoothly, greatly reducing the lag and delay in the video transmission process and providing users with a clearer and smoother video experience.
Appearance and interface pins:
Appearance: USB2.0 is usually a white or black interface; USB3.0 is usually a blue interface, so that users can distinguish it visually.
Interface pins: USB2.0 adopts 4-pin design; USB3.0 adopts 9-pin design, the extra pins provide better support for high-speed transmission and more powerful functions.
Power consumption and power supply capacity:
USB2.0 camera module: the maximum current is 500mA, the power supply ability is relatively weak. For some cameras with high power consumption, if there is no external power supply, the power supply may be insufficient, affecting the normal work of the camera. For example, some cameras that need extra fill light or have complex functions may not be able to perform fully under USB2.0 interface.
USB3.0 camera module: the current can reach 900mA and the output power is about 4.5W, which can provide more sufficient power support for the camera and ensure the stable operation of the camera. Even cameras with high power consumption can work normally under the USB3.0 interface, and can support more external devices, such as fill light, microphone, and so on.
Application Scenario:
USB2.0 webcam module: due to its mature technology and low cost, it is widely used in some scenarios that do not require high video quality and transmission speed, such as ordinary video calls, simple surveillance cameras, and so on. If only for daily network video chat, simple image acquisition and other tasks, USB2.0 camera module can fully meet the demand, and the price is relatively cheap.
USB3.0 Camera Module: It is more suitable for scenarios that require high video quality and transmission speed, such as high-definition video conference, professional live video broadcasting, medical imaging, industrial inspection, etc. In these scenarios, it is necessary to transmit high quality video. In these scenarios, it is necessary to transmit high-resolution, high-frame-rate video data, USB3.0 camera module can provide better performance support to ensure the clarity and smoothness of the video.
Compatibility:
USB2.0 Camera Module: very good compatibility, almost all computers and devices support USB2.0 interface, no additional drivers or settings, plug and play, very easy to use.
USB3.0 Camera Module: Backward compatible with USB2.0, but if you use USB3.0 camera module on USB2.0 interface, the transmission speed will be limited to USB2.0 level. However, with the gradual popularisation of USB3.0 technology, most new computers and devices are now equipped with USB3.0 interface, and the compatibility problem of USB3.0 camera module is gradually decreasing.
