- Turn off the vehicle and listen if the dashcam announces or displays a message indicating "Entering parking surveillance mode".
- If the dashcam successfully enters "Parking Surveillance" mode, restart the vehicle and check if the dashcam turns on normally.
If all the above steps are successful, then the hardwire kit wiring is correct.

5. Operation
The 70mai 4G Hardwire Kit UP04 enables several advanced functionalities for your compatible 70mai Dash Cam:
5.1 24-hour Smart Parking Monitoring
With continuous power from the hardwire kit, the built-in G-sensor in your dash cam can detect sudden shocks or collisions while the car is parked. It will automatically start recording to capture any potential incident. If an emergency video is recorded, the dash cam will alert you with an audio warning once it is turned on again.
5.2 Real-time Monitoring & Instant App Alerts
By inserting a compatible 4G SIM card (not included) into your dash cam, the hardwire kit allows for real-time remote monitoring. You can remotely manage your dash cam and view live footage from inside and outside your car via the 70mai app. The system will also send instant app alerts to your smartphone at the first sign of a suspicious event or collision.
5.3 GPS Car Locator
When paired with the 4G hardwire kit, the built-in GPS system in your dash cam can notify you of your car's parking location and provide walking navigation through the app. With 4G connectivity, you can also remotely monitor your driving routes in real-time. Note: Real-time status is updated every 15 seconds. This feature is currently limited to 15 activations per month.
