IRO APP is specially developed to cooperate with the dash cam products. The APP is connected to the dash cam through WIFI, and can perform function settings, real-time picture preview, video playback, video downloading, and video sharing. The APP uses the RTSP protocol to receive real-time video streams, and uses the HTTP protocol to download and play video files cached in the SD card of the dash cam. The APP supports the playback of TS and MOV files with H264/H265 video encoding and AAC audio encoding. The entire set of software has a beautiful interface and simple operation. It is a highly practical and efficient software.
