Best Settings for the VIOFO A129 PRO Duo Dash Cam

Resolution: 4K (front camera) + Full HD 30fps (rear camera)

For the resolution, our recommended setting is 4K for the front camera and Full HD @ 30 fps for the rear camera. Lower resolutions or 60 frames per second significantly reduce detail.

Bitrate: Medium

The amount of recording time available on your memory card may be reduced if you use high bitrate mode. Using a low bitrate saves space and allows you to record for longer periods of time.

Live Video Source: Your Preference

You can choose from your dash cam's front camera, rear camera, PIP mode 1 and PIP mode 2 options.

Loop Recording: 3 minutes

Three minutes strikes a good balance between finding the desired moment and having to scroll through a large number of files.

WDR (Wide Dynamic Range): OFF

The dynamic range of an image is defined as the ratio of its brightest to darkest areas. WDR allows the camera to produce video with near-perfect exposure in a variety of lighting conditions.

Exposure: 0

You can adjust the EV (Exposure Value) to get better recording results under different lighting conditions. The range is -2.0 to +2.0, and our recommended value is 0.0.

Under parking mode, you have three options for the A129 Pro Duo:

1. Auto event detection: When a moving object is detected during parking, the camera will automatically record for 1 minute. If there are no new movements, it will stop recording.

2. Time lapse recording: Time-lapse recording captures a video at low frame rates of 1 / 2 / 3 / 5 / 10 / 15 fps, and it records continuously without audio.

3. Low bitrate recording: This mode records video at a low bitrate of 4MB/s for both the front and back cameras. It continuously records in mini le size with audio recorded.

Note: We recommend buying VIOFO HK3 ACC hardwire kit cable for parking mode recording.

Parking G-sensor: High

When the G-sensor detects significant or sudden movement (such as an impact or collision), an event recording is initiated. In parking mode recording, we recommend setting it to High sensitivity.

Parking Motion Detection: Mid

This adjusts the detection sensitivity so that minor motion caused by wind or rain does not trigger a recording.

Time-lapse Recording and Motion Detection: OFF

When this feature is enabled, if there is movement in front of the camera, a recording will begin. When the camera detects no movement for 60 seconds, the recording is stopped and the device switches to detect mode. If the device detects a new movement in front of the camera, it will start recording again.

GPS: ON

If this option is disabled, your camera will no longer measure your speed and position, nor will it synchronize the time/date with the atomic clock. Note that it is only available when connected to a GPS signal.

Speed Unit: Your Preference

Sets the speed unit, either in kilometers per hour (KPH) or miles per hour (MPH).

G-sensor: LOW

The force required to prevent the file from being overwritten by loop-recording is determined by this setting, which sensor ranges from 'Low' to 'High'.

Wi-Fi: ON | 5GHz

Activates your Wi-Fi Connectivity. We recommend choosing the 5GHz Wi-Fi mode for faster connection.

Date Stamp: ON

Imprints the time and date on your recorded video.

GPS Info Stamp: Your Preference

Record Audio: ON

This activates or deactivates the microphone. This can also be accessed by holding down the []button while the camera is recording.

Screen Saver: 1 Minute

Boot Delay: 0

When you turn on the camera, it will take a few seconds to boot up. The settings you can choose from are O / 5s / 10s.

All data on the MicroSD card will be erased during the procedure. Once the Micro SD card is formatted, all information on it is lost and cannot be recovered, so make a backup of all important files.
