ZENIX LEF-3
Outdoor BLE Proximity Locator & Gateway | IP67 Rated, GPS, LTE Enabled
What is ZENIX LEF-3
The ZENIX LEF-3 is a durable, outdoor BLE RSSI locator and gateway designed for harsh environments where you need reliable BLE-based proximity tracking. Built with a rugged IP67 enclosure, GPS, LTE connectivity, and external antennas, it scans nearby BLE beacons/tags and forwards signal strength data (RSSI) to your RTLS infrastructure. With its embedded processor running Sentrax firmware and flexible network interfaces (PoE, Wi-Fi, LTE), the LEF-3 is ideal for outdoor RTLS use cases like yard tracking, people safety, and large outdoor assets.
It supports advanced capabilities such as Proximity BLE Tag Tracking, People Tracking, BLE Tags Healthcheck monitoring
Key Features & Benefits
Outdoor RSSI-based BLE Scanning
Uses BLE 5.1 to scan for tag or beacon signals, analyzes received signal strength (RSSI) to infer proximity.
Long-Range Coverage
External antennas provide extended BLE scan range (10–50 m, depending on environment).
Compact, Outdoor Mounting
Comes with a wall or pole mount system for flexible outdoor installation.
Remote Tag Configuration & Updates
Supports remote configuration and firmware updates of connected tags.
How It Works?
The ZENIX LEN-1 is a BLE Indoor Scanner Locator that enables real-time tracking and presence detection across industries, healthcare, and smart buildings, offering reliable performance and easy installation.
