VIOFO T340TW 4CH is a 4-channel dash cam that records 4K front video and 2K secondary views across four synchronized channels. It combines advanced Sony STARVIS 2 sensors with a 4x optical zoom telephoto lens to capture critical road details. This system is designed for professional drivers and vehicle owners who require comprehensive interior and exterior surveillance.
4K Front Camera with Sony STARVIS 2: Captures Crisp Details
The front camera records in true 4K UHD at 30fps using a 1/1.8 inch Sony STARVIS 2 sensor. This sensor configuration provides high dynamic range to maintain visibility in extreme lighting transitions like tunnel exits. Does it capture license plates at speed? Yes, the combination of 4K resolution and advanced light management ensures plates remain identifiable on moving vehicles. It is the ideal primary evidence tool for daily commuters and fleet operators.
2K 4x Optical Zoom Telephoto Camera: Identifies Distant Plates
The dedicated 2K telephoto lens utilizes 4x optical zoom to isolate and record distant vehicles. By zooming in on traffic, it identifies license plates that wide-angle cameras might miss. Is this lens compatible with filters? Yes, it supports an optional CPL-600 lens filter to cut through glare and windshield reflections. This camera is specifically engineered for drivers who need verifiable proof of events occurring far ahead on the road.
2K Infrared Cabin Camera: 210° Ultra-Wide Coverage
The integrated 2K cabin camera features an ultra-wide 210° field of view and built-in infrared LEDs for night recording. It captures the entire interior and side windows in low-light conditions using a 1/1.88 inch sensor. Can it see in pitch black? Yes, the infrared night vision provides clear footage of passengers and cabin activity without needing external light sources. This is a primary requirement for rideshare drivers and fleet supervisors.
2K Waterproof Rear Camera: IP67 Rated Exterior Protection
The waterproof rear camera records in 2K resolution and features an IP67 rating for all-weather durability. It mounts outside the vehicle, making it suitable for trucks, RVs, and trailers that require a clear view behind the cabin. How does it handle rain? Its waterproof housing ensures moisture and debris do not obscure the lens during operation. This unit provides vital rear-end collision evidence in harsh driving environments.

Wi-Fi 6 Connectivity: Faster Video Transfers
Integrated Wi-Fi 6 technology supports both 2.4GHz and 5GHz bands for rapid file downloads to the VIOFO app. This system enables users to preview live feeds and export footage to smartphones without the need for manual cable transfers. Will it work with large files? Yes, the high-speed data throughput is optimized for moving multiple 4K and 2K files quickly. It is ideal for drivers who need to share footage on the spot.

Five Parking Recording Modes: 24/7 Vehicle Surveillance
The system offers five distinct parking modes including Hybrid Parking Recording, time-lapse, and low-bitrate recording. These modes switch automatically between standby and active recording when motion or impacts are detected by the sensor. Can it record for long periods? Yes, it supports low-power impact detection to minimize battery drain while maintaining 24/7 vigilance. This feature is intended for users who park in high-risk areas for extended durations.
Quad-Mode GPS: Precise Location Tracking
Built-in GPS utilizes quad-mode satellite coverage (GPS, BeiDou, Galileo, and GLONASS) to log location, speed, and timestamps. This data is embedded directly into every video file for indisputable evidence during incident reporting. Does it track route history? Yes, the system logs coordinates across every mile to provide a detailed travel record. It is essential for rideshare drivers and long-haul truckers who require verified trip documentation.

Multiplex Video Files: Simplified Multi-Perspective Playback
The T340TW 4CH creates multiplex video files that combine multiple camera feeds into one synchronized view. This allows for simultaneous playback of the front, interior, telephoto, and rear angles without requiring third-party video editing software. How is the footage exported? The app merges these perspectives into a single file for instant sharing and review. It is the fastest way to present a complete, multi-angle incident report.
Hands-Free Voice Control: Multilingual Operation
Supports voice control in English, Russian, Japanese, and Mandarin. Users can issue simple commands to lock footage or take snapshots without taking their hands off the steering wheel. This feature minimizes driver distraction during critical road events. It provides proactive audio alerts for memory card errors or settings changes to ensure the system remains active.

Instant Emergency Locking: One-Touch Footage Protection
Features a dedicated side button for instant emergency file protection. Users can trigger this button to move the current clip into a read-only folder, ensuring it is not overwritten by the loop recording cycle. This provides immediate security for hit-and-run incidents or unexpected road encounters. The G-sensor also triggers automatic locks upon detecting a collision.

Tamper-Resistant Security: Unauthorized Access Prevention
Includes a tamper-resistant cover designed to prevent unauthorized access to memory cards or cable connections. This hardware addition maintains a professional installation by shielding sensitive ports from accidental disconnections or tampering. It is essential for fleet vehicles or drivers requiring secure evidence storage. The cover secures with provided screws to maintain a clean aesthetic.

Dual Type-C Car Charger: 45W Total Power Delivery
Comes with a dual Type-C car charger featuring a 30W fast-charging port and a 15W dash cam power port. The unit includes a soft-glow ring for easy operation in low-light conditions. This configuration allows for simultaneous device charging without sacrificing the power stability required for 4-channel recording. Note that only the specified port is compatible with the dash cam.
