You’re driving, someone pulls into the road, and in a moment you hear: “that’s not me.” The T400 simultaneously captures the front, interior and rear of the vehicle, so you have a more complete picture of the incident without guessing what was out of frame. The cameras’ wide viewing angles of 125° front, 147° interior and 130° rear mean fewer blind spots and more context in the footage when you need to reconstruct the situation.

70mai T400 is triple security
The 70mai T400 video recorder is a clever combination of front, rear and interior cameras that simultaneously record every inch around the car. Wide-angle lenses of 125° in front, 130° in back and 147° inside ensure that the recordings include what matters most – the lanes, the bumper of the car behind you and the situation in the cabin. The driver, family and passengers are better protected, both on daily commutes and on business or customer trips.
Compact and convenient video recorder
The 70mai T400’s compact design combines the front and interior camera in a single body that does not obstruct the view or disfigure the cockpit. The built-in screen shows you in real time what the DVR is recording, so with one glance you’re assured that everything is working as it should. Simple installation makes it easy for even novice users to get started, and the aesthetically pleasing design fits in with modern private and fleet car interiors.
Always clear 1440P HDR recordings
The 70mai T400’s front camera records at 2560×1440 resolution at 30 fps for sharp images and clear details in everyday driving. The HDR technology used equalizes the light and dark parts of the frame, so the license plate number or lane lines remain clear even when exiting a tunnel, under the sun or in cloudy weather.
70mai T400 sees clearly at night
The 70mai T400’s F1.55 high-brightness lens and glass optics let in more light, making nighttime recordings brighter and clearer. A proprietary image algorithm reduces noise, improves exposure and reduces glare, so even distant license plates can be recognized when zoomed in. This is a huge advantage when an incident occurs after dark, in a poorly lit parking lot or side road.
In-cab recording for driver and passenger protection
The 70mai T400’s interior camera has a 147° viewing angle and four infrared LEDs, allowing you to continuously record what’s happening in the cabin – even in total darkness. You can use automatic or manual switching to IR mode, choosing between clear black-and-white images and color recording when there is enough light. Such a solution works well in family cars, larger vans and cars for hauling applications, where passenger and driver safety matters.
Intelligent event recording
The 70mai T400’s buffered emergency recording function records up to 3 minutes before a crash, as well as the moment of impact itself and 30 seconds after, creating a complete picture of the traffic situation. Key clips go into a special “Emergency video” folder, so they won’t be overwritten by standard loop recordings. This is a real support in disputes with the insurer, the driver from the other car or when clarifying ambiguous situations.
*Mode only available with optional Hardwire Kit UP03 or UP06.
GPS recording and accurate routes
The 70mai T400’s built-in GPS module records route mileage, speed and location using several satellite systems such as GPS, Galileo and QZSS. The trip data can be conveniently checked in the 70mai app, making it easy to account for business routes, analyze driving style and verify mileage when in doubt. This is especially valuable for company drivers and those driving in a shared model.
Constant parking surveillance
The 24-hour parking surveillance mode allows the 70mai T400 to record the situation around the car even when the engine is off. The built-in G-sensor with five sensitivity levels – from Extreme High to Extreme Low – reacts to impacts, initiating 30-second recording of the front, rear and interior. So you have footage when someone hits the car in a parking lot, scratches the bumper or bumps a mirror and drives away without leaving contact.
Economical timelapse and super-capacitor
The 1 fps time-lapse recording function in parking mode achieves continuous recording of an entire day with very low power consumption and up to fifteen times less memory usage than in standard mode. At the same time, a long-life supercapacitor ensures safe recording of files even in the event of sudden power loss and better resistance to extreme temperatures. This solution will be appreciated by drivers of cars parked under a cloud and users in hot or freezing climates.
Easy operation with the app
With One-Tap App Connect, the 70mai T400 connects to the 70mai app with a single tap, using Bluetooth to quickly find the device. Once connected, it only takes a moment to review recordings, download them to your phone or change settings without reaching for a computer.
Voice commands and high-speed Wi Fi 6
The 70mai T400 supports voice commands in English and Mandarin, so you can take a picture, start recording or turn off the sound without taking your hands off the wheel. Built-in Wi Fi 6 in the 2.4 GHz band speeds up file transfers between the camera and your smartphone, reducing the time it takes to rip longer recordings from three channels. This is especially convenient when you’re working with multiple videos after a day of intense driving.
Support for large memory cards and flexible menus
Support for microSD cards up to 512 GB allows the 70mai T400 to save about 13 days of recordings with two hours of daily use of all three channels, without the risk of quickly overwriting important files. The system offers a rich list of languages, including Polish, making setup and ongoing operation easy for any user. All this is enclosed in a small casing with a 1.9-inch screen, which blends harmoniously into the car interior.
