Built-in GPS Logger: The D90-4CH car dash camera is equipped with a built-in GPS that accurately pinpoints the vehicle's location, speed (in KMH/MPH), time, and routes on a map in real-time. By installing and using the GPS Video Player, the vehicle's path can be visually tracked, while the coordinates ensure that the exact location of any incident is recorded. This is critical for roadside assistance and insurance claims.Quality Night Vision: The cabin lens has an F1.8 aperture and four infrared lights. This provides round-the-clock protection. This ensures clear recording and superior image performance compared to other dash cams, especially at night.Easy Installation & No Battery: Installation and use are made easy with the reference images provided in our user manual. The dash cam does not include a battery to prevent damage from sun exposure, high temperatures inside the car, or battery malfunction.Loop Recording & Crash Lock: To ensure endless loop recording, the dash cam automatically deletes the oldest unlocked footage when the memory card reaches its maximum capacity. In case of a collision, the dash cam will automatically lock the currently recorded footage as evidence. Locked files will not be overwritten by loop recording.Built-in Wi-Fi Capability: Use our free mobile app to set up your dash cam and instantly share your captured videos on your compatible smartphone, available for both iOS and Android devices. You can download videos directly to your phone and share them with friends and family on any social media platform.
