Product Description

Product Description

Blind Spot Assistance System with Side Mirror Warning Light (79GHz)

BSM (Blind Spot Monitoring) is an advanced active safety technology designed to detect obstacles in the vehicle's side and rear blind spots, such as other vehicles, pedestrians, or objects. It provides visual and audible alerts to help drivers avoid collisions when changing lanes or turning.

The system uses millimeter-wave radar sensors to monitor the environment behind and alongside the vehicle, covering blind spots and offering timely warnings during normal driving or lane changes.

Side Mirror Warning Light Version:

Replaces the original side mirror, integrating the warning light for easy installation. Compatible with most vehicle models.

What is a Blind Spot in the Rearview Mirror ?

The blind spot refers to the areas around a vehicle that cannot be directly seen by the driver through the rearview and side mirrors. These blind spots are typically located just behind and to the sides of the vehicle, near the rear corners. When another vehicle or pedestrian is in this zone, the driver may not notice, which increases the risk of an accident.

Key Features

Function Introduction

Blind Spot Monitoring:

The BSM (Blind Spot Monitoring) function uses rear-mounted millimeter-wave radar to continuously monitor traffic in the vehicle's blind spots. When a vehicle enters the blind spot, the function alerts the driver with visual and audible warnings, reducing the risk of collisions during lane changes.

Lane Change Assist:

The LCA (Lane Change Assist) function provides support warnings when the driver initiates a lane change. By monitoring traffic behind and to the sides of the vehicle, the function alerts the driver if there are obstacles or rapidly approaching vehicles in the blind spot, assisting in a safe lane change.

Door Open Warning:

The DOW (Door Open Warning) function alerts the driver and passengers when opening the doors if there are approaching vehicles (including motor vehicles and bicycles) or pedestrians, providing audible and visual warnings to prevent traffic accidents caused by suddenly opening the door.

Rear Cross Traffic Alert:

The RCTA (Rear Cross Traffic Alert) function monitors cross traffic when the vehicle is reversing or exiting a parking space. If a vehicle or pedestrian approaches from the side, the function issues audible and visual warnings, helping to avoid collisions during reversing maneuvers.

Our Advantages

Product Advantages

1.Custom OEM-standard rearview mirror glass, which fits the original vehicle perfectly for seamless and non-destructive installation. It upgrades the original functions by directly replacing the factory-installed rearview mirror, while ensuring both safety and aesthetics.
2.Adapt to a variety of road conditions: Whether it is the high-speed driving scene of the expressway, or the low-speed driving situation of frequent starts and stops on urban roads and complex intersections, the BSM system can work stably and continue to play a monitoring and early warning role.
3.All-weather operation — reliable performance under harsh weather conditions with no false alarms.
4.Upgradeable to vehicle-specific version by using dedicated wiring harnesses with OEM connectors, ensuring plug-and-play installation without damaging the wiring. Once installed, it acts like an "invisible bodyguard",and does not affect vehicle warranty.

5.Traditional BSM only provides a "beep-beep" warning sound, requiring drivers to interpret the danger themselves, which can lead to misjudgments and distractions. BOTRS BSM offers precise real-voice alerts (e.g., "Attention, vehicle approaching from the right"), directly identifying the risk type for instant understanding without the need for guesswork. It also supports customizable language options, ensuring seamless adaptation for drivers worldwide.
6.Traditional BSM only signals through rear-view mirror indicators or A-pillar lights, which can be easily overlooked (e.g., when taking a call or being distracted). The new BOTRS BSM A-pillar light-strip warning system uses a dynamic ambient light band, making blind spot dangers impossible to ignore.
7.For Honda vehicles, the system can directly display blind spot monitoring information on the OEM central control screen, providing a more intuitive warning. (Applicable only to specific models — please consult customer service for details.)
