Description
The Dakota Alert Smart Break Beam Wireless Kit and Receiver includes two solar powered break beam sensors (send/receive pair) and Dakota Alert’s newest SR-4000 smart receiver with relay outputs. With the new SR-4000 receiver, you’ll receive alerts when a subject passes between the beams instantly up to 1 mile away both locally, as well as via the Dakota Alert App on your favorite smartphone platform once the system has been enrolled on your Wi-Fi network!
The break beam send/receive pair can be installed up to 300 feet apart—perfect for a wide variety of monitoring solutions: from driveways to walkways, front doors, gates, sheds, and many other applications that need precision alarming. Built-in dual-cell solar panels (with optional microUSB input for wired installs) keep the sensors online 24/7 without needing to trench in wiring and need as little as 2 hours of sunlight to keep your batteries fully charged.
When the beam is broken, the beam sensor will activate the SR-4000 smart receiver and play one of 16 customizable chimes or tunes, as well as activate any additional sirens, bells, and other devices that accept a 2-wire connection from the included relays. When connected to your local Wi-Fi network, the smart receiver can also send a push notification to your phone—enjoy the reliability of traditional long-distance radio-frequency alarming with the convenience of a smart device, alerting you to visitors and trespassers alike, no matter where you are!
Simply mount each sensor pair on a flat surface or with a pipe mount with the included fluid level for easy install—up to 16 sensors can be paired to a single receiver, and an unlimited number of 4000-series receivers can be paired to a sensor; perfect for any size of install: from simple home and cottage security, to creative applications for businesses like automatic chiming for customers, or wireless employee alerts for incoming deliveries.
Simple code-learning technology allows you to enroll sensors in seconds, and additional sensors (sold separately) can augment your installation by adding motion sensing, driveway alerting, door/window opening, and more.
Break beam kit is designed for outdoor deployment and can work up to 1 mile away from the indoor plug-in receiver in conditions from -30°F to 120°F—with the longest wireless range in its class, the Dakota Alert SBA-4K kit is a hassle-free wireless detection system that goes the distance.
NEW FOR 2026- This new kit replaces the original SBA-4K kit which did not include Wi-Fi connectivity.
