4K+1080P Dual Dash Cam: The Gleetour G2 dash cam front and rear setup features a 4K Ultra HD front camera and a 1080P rear camera. With its wide 170° front and 150° rear coverage angles, this dash cam captures a broad view of the road, reducing blind spots and recording essential driving moments such as traffic conditions and surroundings for enhanced safety and peace of mind. Superior Night Vision: Equipped with premium optical lenses, a large F1.55 aperture, and six layers of glass, this dash camera for cars integrates HDR, WDR, and 3D DNR technologies, enabling clear recording in low-light conditions and capturing every crucial detail. Memory Card Failure Alert to Protect Data: When the memory card fails (due to damage, disconnection, or incompatibility), the dashcam emits a continuous "DIDI" audio alert to prompt the driver to take immediate action, preventing recording interruptions. Dual storage loops independently to ensure that every second is securely recorded wit
