Does the mirror dashcam only record front camera video?

G840S saves front and rear videos. Click the [playback icon] to enter the playback interface. Then Click the [car-shaped icon] to switch the video interface of the front and rear cameras.

Why the rear camera glares at night?

The fixed focal length of the rear camera is 2.5 meters, and the rear camera works best at this distance. The WDR camera(Asin: B09KRM9QQ5) does a better job of addressing the glare problem.

Rear Camera not detected?

First, please check the AV connector and 4-pin connector (4-pin connector may be loose, you can tighten it and reconnect it) and reconnect the AV connector to check whether the rearview camera can be detected. If still doesn’t work, please tell us.

How to filp/mirror the rear camera image?

If you want to install the rear camera on a pickup, SUV, or even on the top roof more conveniently, please adjust the “Upside Down of Rear Camera” and “Mirror Flip of Rear Image” menus to adjust the rear image vertically or horizontally.

Why is GPS not working?

The vehicle must be within a wide range to receive the signal. We will send a new one if it is still not received in a wide area.

12” LARGER SCREEN & BROAD VIEW – Upgraded from most rearview mirror cameras, WOLFBOX 170° front, and 140° rear lens provide an ultra-wide view, minimizing the blind spots for safe driving/reversing. With the smart screen split function, you can observe a dual-lens display simultaneously. With a 2.5D curved screen, the body is more smooth and more suitable for the curvature of the human retina. Its OEM looking makes the mirror camera perfectly integrate with the existing mirror.
CLEAR IMAGE & ENHANCED NIGHT VISION – With a built-in high-quality chip, the WOLFBOX mirror camera records 4K front and 1080P rear videos. The mirror dash camera applied an upgraded low-reflectivity LCD to reduce reflection during the day. With incorporated WDR&HDR tech balancing the lights, and the help of a starvis sensor and 6-glass lens to capture higher quality images, driving at night or in any challenging lighting situations should be more effortless.
GPS TRACKING ALL THE TIME – With the external GPS antenna plugged in, you can view the GPS info on display while on the wheel. Playback recorded videos on GPS Player, not only can you check the double channel videos on one screen, but also accurately trace back all the GPS metrics.
24H PRECISE PARKING MONITOR – Aside from loop recording for safe driving, your car will still be in safe hands after being parked. The time-lapse mode is there to monitor at very low fps which saves power and capacity while having everything recorded.
NEW UPGRADE, TYPE-C POWER SUPPLY – To make the use process more stable, the G840S Mirror Camera has been fully upgraded from Mini-USB to a Type-C socket, which can largely avoid restarting, high-temperature deformation, and so on. (if you need a hardwire kit, please buy a dedicated Type-C hardwire kit. Asin: B09X1L1GMX)
