Video Codec
Choose between H.265 (HEVC) and H.264 (AVC).
y
H.265 (HEVC) is recommended, particularly for 4K UHD resolution recording. In comparison to AVC, HEVC offers about double the data
compression ratio at the same level of video quality. However, older devices may not support HEVC video playback.
y
H.264 (AVC) can be chosen for compatibility with older desktop and mobile devices.
Image quality
At "4K UHD (Extreme)" resolution the image quality is fixed to Highest (Extreme) (25 Mbit/s). At other resolution settings you can adjust the
recording image quality (bit rate). Choose between:
y
Highest (12 Mbit/s)
y
High (10 Mbit/s)
y
Normal (8 Mbit/s)
These are the maximum bit rates when the resolution is set to "4K UHD (3840x2160) @30fps".
Increasing the image quality will increase the size of the video files. Loading and copying time will increase accordingly. If your phone does
not support video streaming at the ‘highest’ image quality setting, please copy the recording to your phone and play from internal memory.
Alternatively, if you lower the image quality setting to ‘high’ you will be able to stream new recordings.
Enhanced night vision
The dashcam has an intrinsic night vision feature. If you want to enhance it, enable Enhanced night vision.
Brightness
You can adjust the recording brightness level of the dashcam.
