I recently purchased this on Amazon, but I'm selling it due to a change in specifications. It is new and unused. 【4K Ultra HD High-Definition & Simultaneous Front and Rear Recording】The REDTIGER F7N dashcam achieves high-definition 4K UHD (3840×2160P) with 8 million pixels. Equipped with two cameras, it allows for simultaneous front and rear recording. With UHD in the front and Full HD in the rear, it reliably records high-definition, smooth video of accidents, aggressive driving, and other troubles. It's suitable not only for recording accidents but also for recording memories of drives and trips, allowing you to enjoy beautiful footage. 【Equipped with WDR Function】The front camera of this dashcam adopts a superior optical lens with a large F1.5 aperture and 6 layers, and is equipped with a sensor compatible with STARVIS technology, achieving high-definition recording day and night. The front and rear cameras are equipped with WDR/HDR, providing excellent image processing capabilities, and can capture clear images while suppressing "blown-out highlights" and "crushed blacks." Clear images are available even in scenes with large differences in brightness, such as night/rain/snow/fog! 【Equipped with WIFI & Smart Intuitive Operation】As it is equipped with WIFI, you can use the dedicated app (REDTIGER) on your smartphone to control functions such as video and photo shooting, and intuitively perform various operations such as checking, playing, saving, and deleting recorded videos. In addition, you can download and edit videos in the app, and share the scenery and wonderful moments during your trip with your friends and family at any time with one-click sharing. Furthermore, the main unit is designed with a compact and easy-to-remove design, and can be directly connected to a computer with a MICRO cable (ASIN:B08TTZX4QC), making data output easy! 【Built-in GPS, Parking Surveillance, Multi-Function Support】★This dashcam has a built-in GPS, which accurately records the vehicle's driving trajectory, real-time speed, and location (expressed in latitude and longitude), greatly enhancing its ability to provide evidence in the event of an accident. ★Equipped with a parking surveillance function (requires a separately sold dedicated step-down cable), allowing for 24-hour parking surveillance when using the dedicated cable. (With time-lapse function) ★Other multi-functions: LED signal countermeasures & terrestrial digital TV noise countermeasures. Continuous recording, impact recording, loop recording, long-term driving notification (announcement reminder), voice recording, G-sensor, and other functions are packed in. ★Includes a 32GB SD memory card.
