COOAU Dash is a mobile application designed specifically for driving recorders, seamlessly connecting your recorder device for easy viewing, playback, and management of driving videos. Through real-time preview function, ensure recording quality, while providing collision detection and emergency recording saving, ensuring that important moments are not missed. A user-friendly interface and simple operation make safe driving and video management easier. 【 Kind reminder 】 The function of obtaining the user's work trajectory during a certain time period will continue to use GPS positioning services, and switching to the background will still maintain GPS connection, which will consume more power compared to other operations. Continuous operation of GPS in the background will affect battery life.
