? Warm Reminder

The 24-hour parking monitoring uses the vehicle battery power supply, which will consume a certain amount of battery power. If the vehicle battery is older than one and a half years or if you have concerns about controlling battery power consumption during parking monitoring, please turn off the parking monitoring function.

? Description of Video Recording

1. Under 12V voltage, the default setting for time-lapse recording is off. When the car engine is turned off, the recorder shuts down normally. If time-lapse recording is set to On, when the car engine is turned off, the recorder automatically enters the 24-hour monitoring time-lapse recording screen saver state. The video file is recorded at one frame per second. When the card is close to full, the recorder automatically deletes the oldest file, enabling cyclic coverage of the video without missing frames or seconds. After the car is restarted, the recorder lights up the screen and enters regular recording. The duration of each time-lapse recording segment is the same as the loop recording length set in the menu. For example, one minute of recording captures 30 minutes of video under normal time, and three minutes capture 3 x 30 minutes of video under normal time, and so on.
2. Low Power Protection ?: When the car is switched off at low voltage (11.6~11.8V), the machine shuts down normally and enters the low power protection state. After the car is restarted, the machine turns on and enters regular recording.
3. Technical Support ?: If you encounter any problems during use and installation, please contact our technical personnel immediately.
4. Thank you for your purchase. If you have any suggestions for improvement, please contact us. Thank you.
