How to install the GPS
GPS front and back


Installation Location


Position 1: If it is convenient, it is recommended to install the GPS module above the roof of the car to receive the best signal. (This position can be used for recorder function verification before installation)
Position 2: Considering that the front windshield of a motor vehicle has a large enough view of the sky, it is usually recommended that the GPS module be placed in the central console. At the corners of the central console and the edge of the windshield, after adopting hidden wiring, they are fixed with double-sided tape.
Position 3: For customers with strong hands-on ability, it is a good way to install the GPS module in the A-pillar of the car, which can achieve perfect hidden installation.
Considering the use effect and installation convenience, we usually recommend customers to install it at position 2. Of course, you can also try to install it in other locations for testing, and choose the location you think is most suitable.

Movie Clip Time: 1minutes/2minutes/3minutes

Q: Why is every video recording so short?
A: We set the recording interval of each video to l min/2min/3min. This is for the convenience of finding the locked video later.

The main function of the recorder is to record, especially to record emergency video. If each video is too long and the G-Sensor triggers emergency recording when a collision occurs, the video will be locked and cannot be covered by the loop recording, and customers will be difficult to find the video in the subsequent search. You need slide the longer progress bar to find this locked video.n And the capacity of the Micro SD card is limited, if the locked video is too long, the normal video capacity that can be stored will decrease.

Movie Mode: 1296P/1082P/720P
The front camera support 1296P / 1080P / 720P, and rear camera support 1080P, when the front and rear camera is recording simultaneously, the front cam and rear cam will be fixed on 1080P.

Sound Record: ON/OFF
In order to be able to record more comprehensive evidence, we recommend that you tum on this switch.

As a characteristic function of G840S, LDWS (Lane Departure Warning System) is a system that predicts the vehicle’s departure from the lane and warns the driver by sensing the road markings. Accidents caused by lane departure can be said to be high fatalities. Especially when driving on highways, people tend to drive in a straight line and drive leisurely. At this time, LDWS has played a great role.


The LDWS works under these four conditions:

  1. Tab the setting menu” LDWS” ON
  2. Turn the volume of the camera on
  3. 2/3 of the front camera aim to the road.
  4. The road need have the white lines.

When the car crosses the line about 1/3 it will beep in seconds. Otherwise, there may be frequent beeps during driving.

Q: Why does it beep when placed horizontally?
A: If LDWS is turned on, it will stop beeping under the correct usage conditions. Otherwise, it will beep. So, when placed horizontally, the LDWS error warning was triggered.
