USA-BASED WITH EXPERIENCE: Dakota Alert is a South Dakota-based company with over 30 years of experience in the wireless driveway alarm industry. We ensure top quality and customer satisfaction with all of our products. LONG ONE MILE WIRELESS RANGE: The system has the longest wireless range in its class, with a range of one mile compared to other products that only offer a range of ¼ mile or ½ mile. The long range means that the radio signal is more likely to reach the receiver, ensuring reliable and accurate monitoring of your property. Note: This is a transmitter only, and you will need to pair it with one of the 4000 Series receivers. The system has an operating range of -30°F to 120°F. DUAL SOLAR PANELS FOR RELIABLE CHARGING: Each beam unit has two solar panels to help ensure proper charging throughout the day. This helps to keep the system running smoothly and consistently. EASY INSTALL WITH TWO MOUNTING OPTIONS: The system includes mounts for both a flat surface and a pipe mount, making it easy to install. With simple code-learning technology, you can have this system set up in minutes. Up to 16 sensors can be paired with one receiver, or an unlimited number of receivers can be paired to one sensor. UP TO 300 FOOT DETECTION RANGE: The break beam sensors can be spaced up to 300 feet apart. When a person or vehicle passes between the sensors, a signal will be sent to the receiver up to a mile away. This makes it super dependable and ideal for monitoring driveways, back yards, tool sheds, and more.
