- It is recommended to format the SD card through the dash cam's settings menu before initial use.

This image highlights the inclusion of a 64GB Micro SD card, emphasizing its faster speed (up to 100MB/sec), longer service life (5500 write and erase cycles), and reliable non-volatile storage technology.
Operating Instructions
1. Powering On/Off
- The dash cam will automatically power on and begin recording when the vehicle's ignition is turned on.
- It will automatically power off when the ignition is turned off.
2. Touch Screen Interface
The 3.16-inch IPS touch screen allows for intuitive control and navigation through settings and playback.

This image displays the touch screen functionality, allowing users to access settings such as parking monitoring, lapse recording, time zone, IR LED, product information, file browsing, movie mode, movie clip time, LCD power save, clock settings, date format, microphone, and flicker settings.
3. Recording Modes
- Loop Recording: The dash cam continuously records video in segments. When the SD card is full, the oldest unlocked footage is automatically overwritten.
- Emergency Recording (G-Sensor): The built-in G-sensor detects sudden impacts or collisions. In such events, the current video segment is automatically locked and saved to prevent it from being overwritten, providing critical evidence.

This image visually explains the G-Sensor's function in automatically locking video during impacts and the loop recording feature that optimizes storage by overwriting older, unlocked files when the SD card is full.
4. Parking Monitoring
When the vehicle is parked, the dash cam can switch to an energy-efficient surveillance mode. Motion detection triggers recording of suspicious activity around your vehicle. This feature requires a separately purchased hardwire kit for continuous power.

This image depicts the dash cam's ability to guard your car even when parked, showing scenarios of potential theft or collision, and noting that a hardwire kit is needed for this function.
5. GPS Functionality
The built-in GPS module records your vehicle's location and speed, embedding this data directly into the footage. This information can be crucial for insurance claims or legal disputes.
6. Wi-Fi and App Control
The dash cam features 5GHz Wi-Fi for faster video transfers to your smartphone via a dedicated app. The app allows you to remotely adjust settings, view live footage, download, and share recorded clips.

This image illustrates how the dash cam's built-in WiFi allows for easy video download, sharing, live viewing, and replay via a smartphone app. It also shows GPS tracking of location, speed, latitude, longitude, and route, viewable on Google Maps via the "Viidure" app or a GPS player on a computer.
7. Night Vision
Equipped with an F/1.8 aperture, 6-layer lens array, and 8 IR lights, the dash cam enhances night vision capabilities, capturing clear footage in low-light conditions. WDR (Wide Dynamic Range) technology further improves clarity by balancing exposure in varying light environments.

This image demonstrates the dash cam's Super Night Vision with F2.0 aperture, 6-layer lens, 8 IR lights, and 170° wide angle. It also shows a comparison of video clarity in bright, dark, and WDR-enabled conditions, emphasizing the improved detail capture.
