70mai Dash Cam 4K T800 Set

Advanced 3-Channel 4K Recording Solution

The 70mai Dash Cam 4K T800 Set is a sophisticated vehicle monitoring system designed for comprehensive coverage. By utilizing a three-channel configuration, it captures the road ahead, the area behind the vehicle, and the interior cabin simultaneously. This provides drivers with a complete visual record of their journey, ensuring that every angle is covered in the event of an accident or insurance claim.

Equipped with high-performance Sony STARVIS 2 IMX678 sensors for both front and rear units, this set delivers 4K Ultra HD resolution at 30 frames per second. The integration of HDR technology across all three channels allows the system to manage complex lighting conditions, such as entering or exiting tunnels and night-time driving, by balancing exposure to maintain detail in both shadows and highlights.

This dash cam set addresses the growing need for reliable evidence and security for daily commuters, rideshare drivers, and long-distance travelers. With features like 4G compatibility for remote access and a supercapacitor battery for heat resistance, the T800 is built for durability and consistent performance in various environmental conditions.

Key Product Features

Dual Sony STARVIS 2 IMX678 Sensors

Unlike standard setups that prioritize the front camera, the T800 Set uses the Sony STARVIS 2 IMX678 sensor for both the front and rear cameras. This sensor technology is specifically optimized for low-light environments, providing high sensitivity and low noise. The F1.7 large aperture further assists in capturing more light, ensuring license plates and road signs remain legible even in dark conditions.

True 3-Channel HDR Monitoring

The T800 supports HDR (High Dynamic Range) on all three channels: front (4K), rear (4K), and interior (1080P). This ensures that even when the sun is directly in front of the lens or when bright headlights appear behind you, the image remains clear without being overexposed. The interior camera provides 1080P resolution with a wide 147° field of view to monitor passengers and driver activity.

Enhanced Connectivity with Wi-Fi 6 and 4G

The device features dual-band Wi-Fi (5GHz and 2.4GHz) and supports the Wi-Fi 6 protocol. This allows for significantly faster video downloads and firmware updates through the 70mai mobile app. With the optional 4G hardware kit, users can access real-time parking notifications, find their car's location via GPS, and view live feeds remotely.

Intelligent Parking Surveillance

When the vehicle is parked, the T800 remains vigilant. The built-in G-sensor detects sudden shakes or collisions, triggering the Buffered Emergency Recording. This feature saves video footage starting before the actual impact occurs, providing context for the incident. Time-lapse recording is also available to compress hours of footage into minutes, saving storage space while maintaining a continuous record.

Technical Specifications

Advanced Functionality and Safety

Buffered Emergency Recording

Standard dash cams often start recording only after an impact is detected. The T800 utilizes buffered recording, which continuously caches video data. If a collision is detected, the system saves the footage starting from several seconds before the impact, ensuring the cause of the accident is clearly documented.

Supercapacitor Technology

To ensure safety and longevity, the T800 uses a supercapacitor instead of a standard lithium-ion battery. Supercapacitors are significantly more resistant to extreme temperatures, reducing the risk of overheating, swelling, or explosion. This makes the device suitable for use in both very hot and very cold climates.

Voice and App Control

The system supports voice commands in multiple languages including English, Chinese, Italian, and Japanese, allowing drivers to take photos or lock videos hands-free. For deeper customization, the 70mai App provides a user-friendly interface to adjust recording settings, view real-time footage, and manage stored files.

Usage and Installation

• Front Camera: Mount the main unit on the windshield, preferably behind the rearview mirror to avoid obstructing the driver's view.
• Rear Camera: Install the rear unit on the back window using the provided adhesive, ensuring the wire is routed through the vehicle panels.
• Interior Camera: Adjust the interior lens to cover the entire cabin space, utilizing the wide 147° FOV.
• Storage: Insert a high-endurance MicroSD card (not included) between 32GB and 512GB. Formatting the card within the device before first use is recommended.
• 4G Features: To enable remote monitoring and 4G alerts, the 70mai 4G Hardwire Kit (sold separately) must be installed and connected to the vehicle's fuse box.

Frequently Asked Questions

What kind of SD card should I use with the T800?

Due to the high data throughput of simultaneous 4K and 1080P recording, it is recommended to use a U3 or V30 rated MicroSD card with a capacity between 32GB and 512GB. High-endurance cards are preferred for long-term reliability.

Does the 4G functionality require a subscription?

The 4G features require the 70mai 4G Hardwire Kit and a compatible SIM card with a data plan. Any fees associated with the SIM card's data usage are determined by your mobile service provider.

How does the buffered recording work?

The camera constantly records to a temporary buffer. When the G-sensor detects an impact, it moves the buffered video (including the moments before the crash) into the protected 'Event' folder on your SD card so it won't be overwritten by loop recording.

Can I use the dash cam in extreme summer heat?

Yes. The T800 is designed with a supercapacitor and has an operating temperature range of up to 60°C (140°F). However, it is always recommended to use a sunshade when the car is parked for long periods in direct sunlight to protect all vehicle electronics.

Is professional installation required?

While many users can install the front camera via the cigarette lighter port, the 3-channel setup and the optional 4G hardwire kit involve routing cables through the vehicle's trim and connecting to the fuse box. Professional installation is recommended for the cleanest and most reliable setup.
