BSD Blind Spot Detection System — 24GHz Radar

Radar-based blind spot protection. Fitted in an afternoon.

Product Description

This compact 24GHz Blind Spot Monitoring system brings radar-grade lane awareness to any vehicle without the complexity of a full aftermarket installation. Two millimeter-wave radar sensors mount behind your rear bumper and continuously scan the danger zones that your mirrors simply cannot cover — the areas alongside and just behind your vehicle where lane-change collisions happen.

A small LED indicator mounts inside the cabin, lighting up the moment another vehicle enters your detection zone. When you signal a lane change with a car already in your blind spot, the system immediately escalates to a flashing visual and audible warning — the urgency you need to hold your position. With a detection range covering 0.3 to 10 metres and response that works in any weather, this is a reliable, practical safety upgrade that makes every lane change more informed.
