Uniden R4 Extreme Long-Range Laser/Radar

The Uniden R4 Extreme Long-Range Laser and Radar Detector delivers record-shattering detection performance combined with smart GPS technology, giving drivers confident, reliable protection against speed enforcement. Designed for serious drivers who demand the best, the R4 pairs unmatched sensitivity with intelligent filtering so you get the alerts that matter, without the noise that doesn't.

How It Works

The R4's GPS-powered auto mute memory learns your regular routes over time, automatically muting known false alert locations so your drive stays quieter the more you use it. When a genuine threat is detected, clear voice alerts and a vivid multi-colour OLED display deliver the information you need at a glance, without taking your hands off the wheel. The preloaded red light and speed camera database covers fixed camera locations, and both the database and firmware are updated for free to ensure your detector stays current.

Advanced False Alert Filtering

Modern vehicles are packed with blind spot monitoring, adaptive cruise control, and collision avoidance systems that broadcast on the same frequencies as police radar. The R4's best-in-class K and KA band filtering intelligently distinguishes between these vehicle-based signals and genuine enforcement radar, dramatically reducing unnecessary alerts and keeping your focus on the road ahead.
