About the Viofo RTC420
From our tech experts at CEN
The RTC420 is the 2K telephoto camera for the VIOFO A329T series, with 4x optical zoom for picking out number plates and fine detail at a distance. It records through a Sony STARVIS 2 IMX675 sensor with HDR, which balances bright and dark areas so plates stay readable in difficult light. It connects to the front camera and extends coverage beyond what a wide-angle lens can resolve.
Who it suits
A329T owners replacing a damaged telephoto camera, and drivers who want the vehicle ahead captured clearly on motorways and fast roads. It points ahead alongside the main camera rather than covering the rear. For the A229 series, the equivalent is the RTC320.
Our tech experts advise
Fit it under the rear-view mirror using the supplied 3M pad, and connect it to the front camera with the included cable. Aim it straight down your lane, as the narrow zoomed view leaves little margin. The CPL-600 filter fits the RTC420 and cuts windscreen glare. See dash cam installation.
