The
Smart Break Beam 4000 is designed for buyers who want more control over exactly where a trigger happens. Instead of watching a wide motion area, the system creates an
infrared beam between two aligned outdoor sensor posts. When that beam is broken, the included smart receiver sounds the alert and can also send a notification through the Dakota app. That makes it a useful choice for
driveways, gates, private roads, and perimeter openings where a clean crossing point matters more than a wider motion sweep.
The sensor pair uses
solar charging and wireless communication, which makes placement easier on long approaches where running power would be inconvenient. Because this kit uses the
SR-4000 smart receiver, it also fits buyers looking specifically for a
Wi-Fi driveway alarm,
beam driveway sensor, or a Dakota 4000 Series system that can expand into multiple zones later.
