5.1 Initial Power On

Once connected to power, the dash cam will automatically power on and begin recording when your vehicle starts. The LCD screen will display the live view from the front camera (and rear camera if connected).

5.2 DDPAI App Connection

1. Download the DDPAI App from your smartphone's app store (iOS or Android).
2. Turn on the dash cam.
3. Open the DDPAI App and tap 'Add Device'.
4. Select your DDPAI Z40 from the list of available Wi-Fi networks. The default Wi-Fi name usually starts with 'DDPAI_' followed by the model name or serial number. The default password is '1234567890'.
5. Once connected, you can view live footage, access recorded videos, and adjust settings via the app.

5.3 Basic Settings Configuration (via App or Device)

• Video Resolution: Set to 1944P for front and 1080P for rear for optimal clarity.
• Loop Recording: Ensure this is enabled. Videos are recorded in segments (e.g., 1, 3, or 5 minutes). When the memory card is full, the oldest unlocked files will be overwritten.
• G-Sensor Sensitivity: Adjust the sensitivity for emergency recording. A higher sensitivity will trigger recordings more easily during sudden impacts or braking.
• Parking Monitor: Enable this feature for 24-hour surveillance. Requires a hardwire kit (sold separately) for continuous power.
• Date/Time: Ensure the correct date and time are set. GPS will automatically synchronize this.
• Audio Recording: Enable or disable microphone recording.

6. Operation

Understand the various recording modes and features of your dash cam.

6.1 Driving Recording (Loop Recording)

This image highlights three key operational features: Emergency Recording, which locks video upon G-sensor activation; Parking Monitor, providing 24-hour surveillance; and Seamless Loop Recording, which overwrites old files when the memory card is full.

The dash cam automatically starts recording when the vehicle's ignition is turned on. Footage is saved in short segments (e.g., 1, 3, or 5 minutes) to the MicroSD card. When the card is full, the oldest unlocked files are overwritten by new recordings, ensuring continuous recording.

6.2 Emergency Recording (G-Sensor)

In the event of a sudden impact, collision, or hard braking, the built-in G-sensor will detect the event and automatically lock the current video segment, preventing it from being overwritten by loop recording. These files are typically stored in a separate 'Event' folder on the memory card.

6.3 Parking Monitor

When enabled and properly powered (e.g., via a hardwire kit), the dash cam can monitor your vehicle while parked. If an impact or motion is detected, it will automatically record a short video segment. This feature provides surveillance even when the vehicle is off.

6.4 GPS Logging

The built-in GPS module records your vehicle's speed, location, and route data. This information is embedded in the video files and can be viewed during playback using the DDPAI App or compatible PC software.

6.5 Viewing and Downloading Footage

1. Via DDPAI App: Connect your smartphone to the dash cam's Wi-Fi. Open the app, navigate to the 'Album' or 'Playback' section to view recorded videos. You can download desired clips directly to your phone.
2. Via Computer: Remove the MicroSD card from the dash cam and insert it into a card reader connected to your computer. You can then access and copy the video files.

7. Maintenance

Regular maintenance ensures the longevity and optimal performance of your dash cam.

7.1 Memory Card Formatting

It is recommended to format the MicroSD card every 2-4 weeks to prevent data corruption and ensure smooth recording. This can be done through the DDPAI App or the dash cam's settings menu. Formatting will erase all data on the card, so back up any important files first.

7.2 Cleaning the Lenses

Periodically clean the front and rear camera lenses with a soft, lint-free cloth to ensure clear video quality. Avoid using abrasive cleaners.

7.3 Firmware Updates

Check the DDPAI App regularly for firmware updates. Updates can improve performance, add new features, or fix bugs. Follow the in-app instructions carefully when performing an update.
