These alert systems are flexible, fast and easy to install. The sensors will transmit a signal back to a plug in or portable receiver to alert you of visitors or intruders. As wireless technology continues to improve wireless devices become more practical for even long range applications. Driveway alarm systems are no exception, 2000 feet or more is now the standard for wireless driveway sensors. Couple that with the incredible 1 year or more battery lives that most wireless systems can boast and running wires becomes less and less appealing. Wireless driveway alarms are easily our most popular units due to their simplicity of installation. Most even come pre-programmed. Simply pop your battery(ies) into the outdoor driveway sensor and plug the chime in inside. The system will be functional immediately. On top of that, wireless systems are expandable meaning you can have multiple driveway chimes and multiple driveway sensors all working together as part of one complete driveway alarming system.
