🎥 Summary

The technical principle of night vision function

The night vision function of the dash cam mainly relies on infrared technology, wide dynamic range (WDR) and starlight night vision technology.

Infrared technology: Infrared is a kind of light invisible to the naked eye, which can penetrate the darkness and capture the image of the surrounding environment in the absence of visible light. dash cams equipped with infrared technology illuminate the objects in front of them in the dark through infrared lights and receive the reflected light back with the help of an infrared sensor to produce a clear picture.
Wide Dynamic Range (WDR): WDR technology enhances the contrast between light and dark in the image, enabling the dash cam to capture clear details even in situations where there is a high contrast of light, such as areas illuminated by headlights at night and dark areas.
70mai Night Owl Vision™ Technology: This is a technology that uses a weak light source to capture images. It relies on a high sensitivity image sensor to provide clear images even under the faint illumination of starlight or streetlights.

Exclusive Technology

The 70mai Night Owl Vision™ is a proprietary technology integrated into several dash cams from 70mai, designed to enhance nighttime and low-light driving visibility. This feature improves image clarity by employing advanced HDR algorithms, reducing noise, and balancing exposure. It's particularly useful for recording clear footage of essential details such as license plates and road signs, even in challenging lighting conditions.

For example, models like the 70mai Dash Cam 4K A810 and 70mai Dash Cam A500S leverage this technology to deliver sharper images with minimized glare and better control over brightness during nighttime. The wide dynamic range (WDR) also automatically adjusts exposure to ensure balanced lighting, while the large F2.0 aperture enhances light capture, contributing to brighter and more detailed recordings at night.

This system is ideal for drivers who require reliable nighttime surveillance or those who often drive in low-light environments, as it ensures critical road details are not lost in the dark.

Advantages of 70mai Night Owl Vision™

1. Enhance safety when driving at night

Night time is the most common time for traffic accidents, partly because the lack of light makes it difficult for drivers to judge the surrounding situation. The night vision function helps the dash cam to clearly record the road conditions in front of, on both sides and behind the vehicle in the dark. Whether it is road condition information or accidents, it can be accurately captured, providing important evidence for the determination of accident responsibility.

2. Protect the legal rights and interests of vehicle owners

In night driving, accidents or disputes with other vehicles and pedestrians, the night vision function of the dash cam can provide owners with high-quality video evidence, avoiding unclear video due to insufficient light, thus affecting legal judgement.

3. Adapt to various harsh environments

The night vision function is not only applicable to the night of low light, in other bad weather such as fog, rain and other low visibility, it can also maintain good video quality, provide clear pictures, for driving safety escort.

4. Enhance monitoring range

Many vehicles are also subject to scratches and collisions when parked, especially in unattended car parks. A dash cam equipped with night vision function can also monitor at night when the vehicle is switched off, providing all-weather safety for vehicle owners.

The Future Development Trend

With the continuous progress of the dash cam technology, the night vision function is also gradually to more efficient, more intelligent direction. In the future, the night vision function combined with artificial intelligence (AI) technology is expected to realise automatic identification of road conditions and dangerous objects, and can even be linked with the vehicle intelligence system to automatically issue an early warning when encountering potential dangers, helping drivers to react in advance. In addition, the imaging quality under low-light conditions will continue to improve, even reaching image effects close to daytime.

Conclusion

The introduction of the night vision function greatly improves the applicability of the dash cam at night and in low-light environments, and becomes an important tool for ensuring night-time driving safety. It not only provides drivers with reliable evidence, but also plays a key role in enhancing the overall safety of the road. With the continuous upgrading of technology, the night vision dash cam will further exert its advantages and inject new impetus for driving safety.
