The A400 records in QHD resolution of 2560 x 1440, delivering above par clarity and color-accurateness. 145° wide-angle FOV covers at least three lanes of traffic, capturing more events in each frame. With WDR* technology, the A400 automatically adjusts exposure balance when recording in low-light or high-contrast environments. F2.0 large aperture pulls in more light to brighten up dark scenes. With built-in WiFi, the A400 connects to the 70mai App, so you can easily watch real-time footage, take pictures, and download files to your phone!
