4. Operating Instructions

4.1 Power On/Off and Basic Recording

The dash cam will automatically power on and begin recording when connected to power and your vehicle starts. It will power off automatically when the vehicle is turned off.

• Loop Recording: The dash cam continuously records video in 1/3/5 minute segments. When the SD card is full, the oldest unlocked footage will be overwritten automatically.
• G-Sensor (Collision Lock): The built-in G-sensor detects sudden impacts or vibrations. In such an event, the current video segment is automatically locked to prevent it from being overwritten, securing critical footage.
• Manual Video Lock: Press the function button on the dash cam to manually lock the current recording, protecting it from being overwritten by loop recording.

4.2 Wi-Fi Connectivity and App Control

The GKU D200 features integrated Wi-Fi for seamless connection to your smartphone via the GKU GO app (available for iOS and Android). This allows you to view, download, and share recordings directly from your phone.

1. Download the "GKU GO" app from your device's app store.
2. Turn on the dash cam.
3. On your smartphone, go to Wi-Fi settings and connect to the dash cam's Wi-Fi network (SSID usually starts with "GKU-D200" followed by numbers/letters). The default password is typically "12345678".

4.3 24-Hour Parking Monitor

When parked, the dash cam can provide continuous surveillance. This feature requires a Hardwire Kit (not included, but can be requested from GKU support).

• G-Sensor Mode: If an impact is detected while parked, the dash cam will automatically record and lock the footage.
• Time-Lapse Mode: Records at a low frame rate (e.g., 1/2/5fps) to conserve power while continuously monitoring your vehicle. This provides a condensed overview of events during parking.

Note: A Hardwire Kit is required for the 24-hour parking monitor function to operate continuously without draining your car battery. Please contact GKU support for details on obtaining one.

4.4 Voice Prompts

The dash cam provides various voice prompts to inform you of its current status, such as "Started recording," "Stopped recording," "Video Locked," "Memory card error," and "Please format the SD card." Pay attention to these prompts for optimal operation.
