The 2GIG 345S Series Security Sensors represent the latest evolution in wireless security and automation technology, designed to deliver reliable performance, installation flexibility, and enhanced system compatibility. Operating on the 345 MHz frequency, these sensors communicate seamlessly with the full range of 2GIG control panels, including the 2GIG EDGE, GC Touch, and legacy systems. Each 345S sensor is engineered for professional-grade security, offering fast, consistent wireless transmission and intelligent supervision to ensure dependable monitoring for intrusion, environmental, and life-safety applications.
A key innovation of the 345S Series is the introduction of switchable encryption technology. This feature allows installers to toggle between encrypted and non-encrypted communication modes via an onboard switch - reducing inventory complexity and making a single sensor compatible with both new and legacy systems. The encryption feature enhances data integrity by preventing signal interference or spoofing, ensuring secure communication between the sensor and control panel.
Beyond encryption, 2GIG 345S sensors utilize advanced detection algorithms, tamper protection, low-battery monitoring, and long-life lithium power sources, offering multi-year performance with minimal maintenance. Together, these features make the 2GIG 345S line a powerful, flexible solution for modern home and commercial security - combining robust protection, installer convenience, and smart system integration.

345S sensors work with the all-new GC Touch, revolutionary 2GIG EDGE, and earlier security & control panels from 2GIG.
Easily choose encrypted/non-encrypted operation with an internal switch. 2GIG 345S sensors work for any installation.
2GIG products are known for quality and field-proven reliability with more than 5 million security panels and 25 million devices deployed that boast a less than 0.03 percent failure rate - the best in the industry
