Front Camera Only: 2560 x 1440P 30fps, 1920 x 1080P 30fps
Front + Rear Camera: 1440P 30fps + 1440P 30fps, 1080P 30fps + 1080P 30fps
• Loop Recording: Off / 1 / 2 / 3 / 5 / 10 minutes.
Recording will begin automatically after powering on with a microSD
card in the device. Each recorded file is up to three minutes long, with
old footage being replaced when microSD card storage is full.
• Video Bitrate: You can set the bitrate for video. High bitrate may
improve the quality and smoothness of the video, especially when
recording fast motion or high contrast scenes. Using high bitrate
mode may decrease the amount of recording time available on your
memory card. Using low bitrate will save space and record for longer
time.
• WDR (Wide Dynamic Range): Dynamic range is the ratio of the
brightest portion of the image to the darkest portion of the image.
WDR enables the camera to deliver video with near perfect exposure
in varying lighting situations.
• Exposure Value (Front & Rear): Adjusting the value of the EV
(Exposure Value) properly can create better footage under different
light sources. It ranges from -2.0 to +2.0. You can adjust the EV for
front and rear camera separately. Default is set at 0.0.
• Record Audio: Turn on and off the microphone. This can also be
changed during recording by pressing the microphone button [ ].
• G-Sensor: The G-sensor measures shock forces and locks the video
recorded at the time. The settings from “low to high” determine the
amount of force needed to lock the file from being overwritten. We
recommend that you set it at low.
• Wi-Fi: Set it On / Off. Press the [ ] button for 3 or 5 seconds to
enable Wi-Fi quickly. We recommend to choose 5GHz Wi-Fi mode.
• Parking Recording: There are 3 options under parking mode:
① Off
The camera won’t enter parking mode after the ignition is off.
② Auto Event Detection
The camera will automatically record for 45 seconds while a
moving object is detected while car is parked.
③ Time Lapse Recording
Time lapse record a video at low frames at 1 / 2 / 3 / 5 / 10 fps,
it keeps recording continuously without audio recorded.
④ Low Bitrate Recording
This mode record video in low bitrate for both front and rear. it
keeps recording continuously in mini file size with audio recorded.
Note: We recommend to buy VIOFO HK4 ACC hardwire kit cable for
parking mode recording.
• Parking Motion Detection: Adjusts the sensitivity of the motion
detection so minor motion caused by wind or rain doesn't trigger a
recording.
• Parking G-sensor: The G-sensor detects significant or sudden
movement (such as an impact or collision), it will trigger an event
recording. We suggest setting it to High sensitivity in parking mode
recording.
• Enter Parking Mode Timer:
Set the timer for entering parking mode. (Only for the camera
