Wireless Door/Window Contact
The Wireless Door/Window Contact provides essential perimeter protection for your home or business by detecting when doors and windows are opened or closed. This compact sensor consists of two components - a main sensor unit and a magnet - that create an invisible security field. When a door or window is opened, the magnetic connection is broken and an instant alert is sent to your security panel, triggering your alarm system and notifying our monitoring center. Designed for reliability and longevity, this wireless contact sensor operates on long-lasting lithium batteries that can provide years of dependable service. The built-in tamper protection ensures that any attempt to remove or disable the sensor will immediately trigger an alert, preventing potential security breaches. The wireless design eliminates the need for complicated wiring, making installation clean and efficient while maintaining the aesthetic appeal of your property. Whether you're securing a residential home, retail store, office building, or warehouse, these door and window contacts form the foundation of any comprehensive security system. Smart Shield Systems recommends wireless contacts for their versatility, reliability, and ease of integration with modern security panels. Our professional installation ensures optimal sensor placement and proper system programming for maximum protection. With professional installation by Smart Shield Systems, your Wireless Door/Window Contacts will be strategically positioned and fully integrated with your security system and monitoring services.
