Bitrate is the number of bits per second. The symbol is bit/s. It generally determines the size and quality of video and audio files: the higher the bitrate, the better the quality, and the larger the file size because File size = bitrate (kilobits per second) x duration. In most cases, 1 byte per second (1 B/s) corresponds to 8 bit/s.
Video bitrate affects video quality in several ways. First, it is the key measure of any video file size. Secondly, high video bitrate results in high video quality, and low bitrates result in poor video quality.
Low Bitrate Recording
The low bitrate recording aims to help you save hours of footage as small files (1080P@15FPS or 720P@15FPS) to save SD card space. If no movement is detected after 5 minutes of recording, the resolution of all current video will be automatically switched to 1080P 15FPS or 720P 15FPS for recording, and the recording duration will be determined according to the currently set loop recording duration while greatly improving memory card storage efficiency. When the camera vibrates or is moved, it will automatically exit, wait 5 minutes, and enter again.
This method of recording also conserves space on the SD card but is less efficient. Low bitrate recording decreases the quality of the video to maximize the recording quantity.
Low Bitrate recording can only be engaged when the camera is turned on. Once the camera is turned off, the Low Bitrate recording will not work.
