4. Operating Instructions
The BlackVue DR900X-2CH Plus is designed for intuitive operation, primarily managed through the BlackVue app on your smartphone or tablet.
- Automatic Recording: The dashcam automatically starts recording when the vehicle's ignition is turned on. It records in a loop, overwriting the oldest files when the microSD card is full, unless those files are marked as event recordings.
- Wi-Fi Connectivity: Activate the dashcam's built-in Wi-Fi to connect your smartphone. This allows you to view live footage, access recorded videos, adjust settings, and update firmware via the BlackVue app.
- GPS Functionality: The integrated GPS module records your vehicle's speed and location data, which can be viewed during video playback in the BlackVue Viewer software.
- Event Recording: The dashcam features an impact sensor that automatically triggers event recording upon detecting significant impacts or sudden changes in speed. These files are protected from being overwritten.
- Manual Recording: A dedicated button or gesture control on the dashcam allows for manual triggering of event recordings.
5. Parking Mode
The BlackVue DR900X-2CH Plus offers advanced Parking Mode functionality to protect your vehicle when parked. When hardwired to your vehicle's power, the dashcam automatically switches to Parking Mode after the ignition is turned off.
- Motion and Impact Detection: In Parking Mode, the dashcam monitors for motion and impacts. It records buffered event videos when motion or impact is detected, ensuring you capture incidents before and after they occur.
- Time-Lapse Recording: For continuous surveillance with minimal storage usage, the dashcam can record in time-lapse mode during parking.
- Voltage Monitoring: The built-in voltage monitor prevents your vehicle's battery from draining by automatically shutting down the dashcam if the battery voltage drops below a configurable threshold.
- Parking Mode Event Notifications: If connected to the BlackVue Cloud, you can receive push notifications on your smartphone when an impact is detected in Parking Mode.
6. Cloud Connectivity (Optional LTE Module)
The BlackVue DR900X-2CH Plus supports BlackVue Cloud services, providing remote access to your dashcam from anywhere. This functionality requires an optional BlackVue LTE Connectivity Module (CM100GLTE) connected via the USB port.
