![ZENIX LEN - 2](https://sentrax.com/wp-content/themes/woodmart/images/lazy.svg)

ZENIX offers advanced IoT-based locator and gateway systems for Smart Building, Healthcare, and Industrial environments. The [ZENIX LEN-2](https://sentrax.com/product/zenix-len-2/), a BLE Scanner/Locator, captures real-time beacon sensor data and position information using its external antenna, which enhances indoor coverage. With PoE and Wi-Fi connectivity, it delivers efficient data collection across wider ranges. Powered by Sentrax’s embedded BLE scanning firmware, the LEN-2 ensures high-performance scanning and features an easy wall/ceiling mounting system for quick installation.
