6.1. Basic Recording

The CS-21FH automatically starts recording when the vehicle's engine is turned ON and stops when the engine is turned OFF. Recording status is indicated on the display and via voice assist.

6.2. GPS Functionality

The device utilizes ultra-fast GPS, supporting GPS, GLONASS, Galileo, and SBAS satellites. This allows for highly accurate positioning even in urban areas with tall buildings or mountainous regions.
