NOTE: The dash cam set comes with a car charger ton connect the car cigarette lighter to use, be sure your car has cigarette lighter, if not, you can use our hardwire kit or reach out to us to get an USB charging cable. The operating temperature range for the dash cam is -4°F to 167°F (-18°C to 75°C). We recommend avoiding prolonged exposure to direct sunlight, especially during summer, as it may shorten the camera’s lifespan and potentially damage the screen. 【4k Ultra Hd Resolution & Wide Viewing Angle】The FOCUWAY D2-Duo captures footage in stunning 4K Ultra HD (3840*2160p) resolution for the front camera and full HD 1080P for the rear camera, ensuring crystal-clear video with smooth playback. The new 170-degree wide-angle lens covers more of the road and surroundings, helping you capture crucial details such as vehicle number plates and road signs. 【New 3.39” Screen & Smart Voice Control】Enjoy enhanced live video preview and playback with the IPS screen, which showcases richer colors and optimizes images for a true-to-life viewing experience (Please avoid exposing the screen to high temperatures for extended periods, as this may cause damage such as blurriness or colored lines.). Stay fully focused on driving with smart voice control, allowing hands-free operation. Simply say "lock the video" to save critical moments without distraction. 【Faster 5ghz Wifi & Built-In Gps Tracking】Experience faster performance with cutting-edge 5GHz WiFi, surpassing traditional 2.4GHz connections. Effortlessly preview, download, and share your journeys with the free app. The built-in GPS logs vehicle speed, driving routes, and real-time latitude/longitude, which can be viewed via the app or replayed on your PC. 【24-Hour Parking Monitoring & Loop Recording】The FOCUWAY D2-Duo offers two parking modes: 1) Collision detection mode activates recording when a collision is detected, saving a 30-second emergency video; 2) Time-lapse mode continuously records while consuming minimal power by capturing one frame per second. Seamless loop recording ensures the oldest videos are overwritten with new footage, preventing memory card full issues. A hardwire kit (B0BG5DM5CL) is required for parking mode functionality. 【Advanced Night Vision】Equipped with an advanced STARVIS sensor, f/1.5 large aperture lens, and WDR/HDR technology, the dash cam excels in low-light conditions.
