True 4K with Hardware HDR
The 4K A800SE records true 4K UHD (3840x2160) at 30FPS, delivering sharp, vivid footage of crucial details. Its hardware-level HDR ensures balanced, natural video by perfecting shadows and highlights, ideal for all lighting conditions, including challenging scenarios like tunnels or night driving. This means clear, confident, and uncompromised evidence when it matters most.
Super Night Vision
Buffered Emergency Recording
The Buffered Emergency Recording system now captures up to 3 minutes before a collision, along with 30 seconds after the impact. This ensures you don't just record the accident — you capture the full context leading up to it and what happens next.
Loop Recording
The 4K A800SE records in a loop, automatically overwriting older files with the latest recordings, ensuring uninterrupted footage without storage concerns. Crucially, all emergency and parking surveillance videos are protected in separate "Event" and "Parking" folders, preventing them from being overwritten by regular loop recordings.
24H Smart Parking Surveillance

Up to 512GB Storage Support
More space for what matters. The 4K A800SE supports microSD cards up to 512GB, allowing for extended recording time and reducing the risk of overwriting important videos.
