Why does my nextech 3848 continuously turn on and off, when I am driving. what is the remidy for this?
Here are some possible reasons why your Nextech 3848 dashcam is turning on and off while you are driving, and some potential remedies:
Power Supply Issues:
The most common reason for a dashcam to turn on and off intermittently is a problem with the power supply. This could be due to a loose connection between the car charger and the cigarette lighter port, a faulty car charger, or a problem with the wiring in your vehicle.
Remedy: Ensure that the car charger is properly plugged into the cigarette lighter port and that the connection is secure. Try using a different car charger to see if that resolves the issue. If the problem persists, it might indicate a wiring problem in your vehicle, which would require professional inspection.
Low Battery:
The Nextech 3848 has a built-in battery, but it’s primarily designed to operate using the car charger. If the battery is low, the dashcam may turn off when the car is turned off and turn on briefly when it senses motion, such as when you start driving.
Remedy: Ensure that the dashcam is properly connected to the car charger and that it has sufficient time to charge. You can also try formatting the SD card to see if that helps.
Parking Monitor Feature:
The Nextech 3848 has a parking monitor feature that is designed to automatically record video when the camera detects vibration while the car is parked. This feature could be causing the dashcam to turn on and off even when you are driving if it is too sensitive.
Remedy: You can try adjusting the sensitivity of the parking monitor feature or disabling it completely if you do not need it. Refer to your user manual for instructions on how to do this.
G-sensor Sensitivity:
The G-sensor is responsible for detecting sudden movements or impacts, triggering the dashcam to record emergency videos. If the G-sensor is too sensitive, it might be triggering the dashcam to turn on and off due to minor vibrations while driving.
Remedy: You can try adjusting the sensitivity of the G-sensor. You may need to consult the user manual for specific instructions on how to do this.
Software or Firmware Issues:
In some cases, the problem could be due to a software or firmware issue with the dashcam.
Remedy: You can try updating the firmware of the dashcam. You can find the latest firmware and instructions on how to update it on the manufacturer’s website. You can also try resetting the dashcam to its factory settings.
