VIOFO RTC320 Telephoto Camera – 2K 4x Zoom for A229 Plus & A229 Pro

Read Plates Three to Five Cars Ahead. The RTC320 telephoto camera for the A229 Plus and A229 Pro

A wide-angle dash cam is built to capture the whole scene, which is exactly why it struggles with the thing you often need most: the plate on a car several lengths in front. The RTC320 adds 4x optical zoom on a Sony STARVIS 2 IMX675 sensor, and VIOFO rates it as capturing plates three to five car lengths ahead in normal conditions.

Who This Isn't For — read this before ordering: The RTC320 connects to the Type-C rear port. On a 2CH or 3CH A229 setup that is the same port your rear camera uses, so fitting the telephoto means disconnecting your rear camera. You are choosing between rear coverage and forward zoom, not adding a channel. If you want telephoto alongside a rear camera, that needs an A329T with its dedicated telephoto port and the RTC420. This also fits the A229 Plus and A229 Pro only, and is not cross-compatible with the A329 platform.

DCG Score & Highlights

What We Love

• 4x optical zoom, which is real magnification rather than digital cropping
• Sony STARVIS 2 IMX675 recording 2K at 30 fps with HDR
• VIOFO rates it for plates three to five car lengths ahead in normal conditions
• Works across all A229 Plus and A229 Pro configurations
• Short 0.6 m cord keeps the install tidy when mounted beside the front unit

What Could Be Better

• It shares the rear port. On a 2CH or 3CH system you lose the rear camera to gain the telephoto.
• A narrow field of view means it sees far but not wide, so it complements a front camera rather than replacing one.
• A229 platform only, and not interchangeable with the A329's RTC420 despite the similar name.

Why Optical Zoom Beats Digital Every Time

Digital zoom crops pixels you already have, so enlarging a distant plate just makes the blur bigger. Optical zoom uses the lens to gather genuine detail before the sensor records it. On a motorway, where the car that matters is often several lengths ahead, that is the difference between a plate you can hand to police and one you cannot.

Top Benefits

• Distant plates stay readable: 4x optical zoom resolves detail a wide lens simply cannot.
• Strong low light: Sony STARVIS 2 IMX675 with HDR holds detail after dark.
• Covers every A229 Plus and Pro config: Works on 1CH, 2CH and 3CH systems.
• Tidy install: The 0.6 m cord suits mounting next to the main unit.
