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 is a good fit if you want a Wi-Fi driveway alarm or a beam sensor in a Dakota 4000 Series system that can expand into multiple zones later.

For smartphone alert features and compatible add-ons, this kit also pairs naturally with other Dakota 4000 Series products across the same property.
