3X 433MHz WiFi Signal Repeater & Wireless Extender — 500m Long-Range Booster for Home Alarm Security, Barrier-Free Through-Wall Coverage

Extends alarm detector signals up to 500 meters using multi-arc coverage that reaches corners and hard-to-reach areas. The repeater amplifies the signal sent by your signal detector so the host can receive it reliably. Designed to push wireless transmissions through walls with minimal blind spots: the auxiliary detector’s signal can pass barriers, and you can add the expander in locations with poor reception based on the specific environment. For faster, more stable expansion place the paired amplifier between the detector and the host area to significantly improve detector signal strength. Includes a detachable antenna — install it to increase the amplifier’s transmission and reception range.
