I am selling a brand new, unused 4K dashcam, the D17. It has front and rear cameras that simultaneously record high-definition 4K video, capturing clear footage of license plates and road signs even in daylight, at night, or in backlit conditions. The HDR correction function prevents overexposure and underexposure. It supports high-speed transfer via Wi-Fi, and you can easily view and share videos using the dedicated app. Equipped with GPS and a G-sensor, it automatically records driving routes and impacts, providing solid evidence in the event of an accident. The 360-degree rotating rear camera is easy to install without any construction. The parking surveillance function supports impact detection and time-lapse recording for long-term monitoring. It is compatible with LED traffic signals and has noise countermeasures, ensuring a reliable design for Japanese specifications.
