VIOFO RTC420 2K HDR Telephoto Camera Set | 4x Optical Zoom & Sony STARVIS 2

The Ultimate Add-on for License Plate Capture - Designed for A329S, A329T & A329TW Series

Overview

Take your vehicle's surveillance to the next level with the VIOFO RTC420 2K HDR Telephoto Camera. While standard wide-angle dash cams are excellent for capturing the overall scene, the RTC420 is purpose-built to zoom in on the most crucial details: license plates.

Powered by the industry-leading Sony STARVIS 2 IMX675 sensor and featuring true 4x Optical Zoom, this camera complements your main front camera by magnifying the road ahead. Whether it's high noon or the middle of the night, you can trust the RTC420 to deliver perfectly balanced, crystal-clear 2K footage of vehicles up to 3 to 5 car lengths away.

Why Add the RTC420 to Your Setup?

True 4x Optical Zoom

Unlike digital zoom which degrades image quality and creates pixelated footage, the RTC420 uses a physical optical zoom lens. It captures distant objects at full 2K resolution, making it highly effective for recording readable license plates far beyond the reach of standard dash cams.

Sony STARVIS 2 IMX675 Sensor

Equipped with cutting-edge Sony STARVIS 2 technology, this telephoto camera boasts exceptional low-light performance. It easily cuts through the darkness, maintaining pristine image quality and readability even under streetlights or direct headlight glare.

Advanced HDR (High Dynamic Range)

Never miss a detail due to overexposure or dark shadows. VIOFO's advanced HDR technology automatically balances extreme lighting conditions, ensuring accurate plate capture whether you are driving into direct sunlight or navigating pitch-black roads.

Simple & Clean Installation

Mount the RTC420 directly on your front windshield next to your main A329T unit. Just attach it under or behind the rear-view mirror using the included 3M adhesive sticker, plug in the connecting cable, and point it straight ahead.
