| Video Resolution | 4K UHD | 3,840 × 2,160 pixels; 16:9 image format | Provides greater detail for reading road signs, lane markings, and vehicle features than Full HD. | Confirm recorded file dimensions and inspect footage at normal playback speed. |
| Frame Rate | 30 frames per second | 30 fps at the selected 4K recording profile | Creates smooth motion while maintaining high image resolution. | Measure the actual frame rate from sample files rather than relying only on menu settings. |
| High Dynamic Range | HDR video processing | Balances bright highlights and dark shadow areas in high-contrast scenes. | Helps preserve usable detail when entering tunnels, facing headlights, or recording under strong sunlight. | Test footage in backlit conditions, at night, and during rapid changes between light levels. |
| Viewing Angle | Approximately 140° diagonal | Wide-angle coverage designed to capture the forward road scene without excessive distortion. | Expands side-to-side coverage at intersections and during lane changes. | Verify the measured diagonal angle and check edge distortion in a fixed test scene. |
| Video Compression | Efficient modern codec | H.265/HEVC can reduce file size compared with H.264 at a similar visual quality level. | Allows longer recording time on the same storage capacity. | Check codec compatibility, average bitrate, playback stability, and file integrity. |
| Storage Support | High-endurance microSD storage | Use a card rated for continuous video recording; capacity and supported speed should match the recording bitrate. | Reduces recording errors and premature card wear during repeated overwrite cycles. | Run a continuous recording and loop-overwrite test using the specified card capacity. |
| Loop Recording | Selectable 1, 3, or 5-minute clips | Oldest unlocked clips are automatically overwritten when storage is full. | Maintains continuous recording without requiring manual file deletion. | Check clip continuity, timestamps, audio transitions, and emergency-file protection. |
| Low-Light Recording | Large-aperture lens with noise-controlled processing | Image quality depends on sensor sensitivity, lens aperture, exposure control, and image processing. | Improves visibility of road details in nighttime and poorly lit environments. | Compare nighttime footage for motion blur, glare, noise, and license-plate readability. |
| Impact Protection | Three-axis G-sensor with adjustable sensitivity | Detects sudden acceleration or impact and protects related video files from loop overwriting. | Helps preserve evidence after collisions or severe road shocks. | Perform controlled shock simulations and confirm protected-file behavior. |
| Operating Temperature | At least −20°C to 60°C target range | Actual limits depend on the electronics, battery or supercapacitor, enclosure, and mounting materials. | Supports reliable use across common winter and summer vehicle conditions. | Validate startup, recording, charging, and file preservation in temperature-controlled tests. |
| Power-Failure Protection | Supercapacitor-based shutdown support | Provides short-duration power for safe file finalization after the vehicle supply is interrupted. | Reduces the risk of corrupted or incomplete final recordings. | Disconnect the external power source during recording and verify that the final file remains playable. |
