RTC320 Telephoto Dash Camera
The RTC320 uses a Sony STARVIS 2 IMX675 image sensor with 2K resolution, capturing fine details such as road signs and number plates at a distance.
HDR Capability
HDR technology prevents overexposure and automatically balances lighting in dark or high-contrast areas, keeping footage sharp and clear.
Getting Closer to Details
The telephoto lens uses a focal length longer than the diagonal of the image to zoom in on distant subjects, making it well suited to reading number plates in traffic.
Easy Installation
Attaches to the windscreen with an included 3M adhesive pad and connects directly to the front camera. To keep your A229 running on long journeys or in parking mode, the Viofo HK4 hardwire cable is compatible with the A229 series.

About the Viofo RTC320
From our tech experts at CEN
The RTC320 is the 2K telephoto module with 4x zoom for the A229 series, giving magnified detail of the road ahead rather than a wide view.
Who it suits
A229 owners who want to read plates at distance, particularly for motorway driving and reporting incidents to police.
Our tech experts advise
It replaces the usual second camera rather than adding to it, so decide whether distance detail or rear cover matters more to you. See all rear and cabin cameras.
