The DDPai Z90 is a comprehensive triple-channel dash cam system designed to monitor the road ahead, the area behind, and the vehicle's interior simultaneously. Its front camera captures footage in Ultra HD 4K resolution at 30 fps, while the interior and rear cameras provide high-definition recording at 2880 x 1620 and 2560 x 1440 pixels respectively. To ensure clear images regardless of lighting, the system employs Triple HDR technology, which automatically optimizes exposure across all three lenses. This setup offers wide coverage with a 143° front field of view, a 148° interior view, and a 126° rear view. The lenses feature varying apertures, including a bright F1.5 for the interior and F1.75 for the front, helping to maintain visibility in dim conditions. A compact 3-inch integrated screen with a 640 x 360 pixel resolution allows you to manage settings and review clips directly on the device. Weighing 204.5 g and measuring 83.0 x 67.5 x 46.3 mm, the main unit fits discreetly on your windshield without obstructing your view, making it a practical choice for rideshare drivers or families who need full-cabin security.
