1.3 Installing the Memory Card
Insert a Class 10 Micro SD Card (16GB to 128GB recommended) into the TF Card Slot on the top of the DVR mirror. Ensure it clicks into place. A high-quality, high-speed card is crucial for normal operation.

1.4 Connecting Power
Connect the provided car charger to the TYPE-C port on the DVR mirror and plug the other end into your vehicle's cigarette lighter socket. The DVR will typically power on automatically with the car ignition.
1.5 Rear Camera Installation (Optional)
If your package includes a rear camera, connect its cable to the AV-IN port on the DVR mirror. The red cable wire from the rear camera should be connected to your car's reverse lamp power's positive pole (+). This enables the parking assist line feature when reversing.

1.6 Hardwire Kit (Buck Line) Installation for 24H Parking Monitoring (Optional)
For 24-hour parking monitoring, a hardwire kit (buck line) is required. This connects directly to your car's fuse box to provide continuous power. You will need to identify two fuse slots:
- A fuse slot that provides constant power (RED wire connects here).
- A fuse slot that provides power only when the key is in the ACC position (YELLOW wire connects here).
- Connect the BLACK wire to a grounding screw or bolt in your vehicle.

1.7 GPS Module Installation (Optional)
If you have the optional GPS module, connect it to the designated GPS port on the DVR mirror. Ensure the module has a clear view of the sky for optimal signal reception.
2. Operating Instructions
2.1 Power On/Off
- Automatic: The DVR will automatically power on when your car engine starts and power off when the engine is turned off.
- Manual: Press and hold the power button (located on the bottom edge, as shown in the dimensions image) to manually turn the device on or off.
2.2 Touch Screen Interface
The 9.66-inch IPS touch screen allows for intuitive control. Swipe left/right to switch between front and rear camera views, and swipe up/down to adjust the viewing angle. Tap icons to access settings, playback, and other functions.
2.3 Recording Modes
- Loop Recording: The DVR continuously records video in segments (e.g., 1, 3, or 5 minutes). When the memory card is full, the oldest unlocked files are automatically overwritten.
- G-Sensor: In the event of a sudden impact or collision, the built-in G-Sensor automatically detects the event and locks the current video file, preventing it from being overwritten.
- Parking Monitor: When enabled (requires optional buck line), the DVR will automatically start recording if it detects a collision or vibration while the vehicle is parked.
- Time-Lapse Video (Optional): With the optional buck line, this feature allows the DVR to record at a lower frame rate (e.g., 1 frame per second), significantly extending recording time and saving memory card space for 24-hour surveillance.

- Front Camera View: Displays only the front camera feed.
- Rear Camera View: Displays only the rear camera feed (if connected).
- Picture-in-Picture: Displays both front and rear camera feeds simultaneously.
2.5 Night Vision

2.6 WiFi Control
Connect your mobile phone to the DVR via Wi-Fi using the dedicated app (e.g., Viidure). This allows you to remotely control recording, view live footage, playback recorded videos, adjust settings, and download files to your phone.

2.7 GPS Functionality (Optional)
If the optional GPS module is installed, the DVR will record your driving route, location, and speed. This data can be viewed on a GPS player, providing extra proof in case of an accident.

2.8 Language and Resolution Settings
You can adjust the OSD (On-Screen Display) language and video resolution through the DVR's settings menu. The available resolutions include 3K+2.5K, 2.5K+1080P, and 1080P+1080P.
3. Maintenance
3.1 Memory Card Management
To ensure optimal performance and prevent data corruption, it is recommended to format your Micro SD card regularly (e.g., once a month) through the DVR's settings menu. This will erase all recorded data, so back up any important files beforehand.
3.2 Cleaning
Use a soft, dry, lint-free cloth to clean the DVR screen and camera lenses. Avoid using abrasive cleaners or solvents, as they may damage the surfaces.
4. Troubleshooting
- DVR not powering on: Ensure the car charger is securely plugged into both the DVR and the cigarette lighter socket. Verify that your vehicle provides a 12V power supply; a 24V supply can damage the motherboard. If using a buck line, check all connections (BAT+, ACC, GND).
- Recording issues (skipped frames, corrupted files): This is often caused by a low-quality or slow Micro SD card. Always use a high-quality Class 10 TF card (16GB to 128GB). Format the card regularly.
- Rear camera not displaying: Check that the rear camera cable is securely connected to the AV-IN port on the DVR. Ensure the red wire of the rear camera is correctly connected to the positive pole of your car's reverse lamp.
- GPS not working: Confirm that the optional GPS module is connected properly and has a clear, unobstructed view of the sky.
- Wi-Fi connection issues: Make sure the dedicated mobile app (e.g., Viidure) is installed correctly on your smartphone. Ensure the DVR's Wi-Fi function is enabled in the settings.

7. User Tips
- Professional Installation: For complex wiring, such as connecting the rear camera's reverse trigger or installing the buck line for 24-hour parking monitoring, it is highly recommended to seek professional assistance to ensure correct and safe installation.
- Memory Card Quality: Always use a high-quality Class 10 Micro SD card (16GB to 128GB) from a reputable brand. Using lower quality or slower cards can lead to recording errors, skipped frames, or corrupted video files.
- Original Power Charger: To ensure stable operation and prevent potential damage, always use the original power charger provided with your E-ACE A56 DVR. The built-in battery is very small and is only intended for saving time and settings, not for continuous operation.
- 24H Parking Monitor: If you intend to use the 24-hour parking monitoring feature, remember that it requires the optional hardwire kit (buck line) to be correctly installed to provide continuous power to the DVR even when the car is off.
