4Mining Personnel Tag Watch-1-LoRa — LoRaWAN safety smartwatch

Powered by 4MTracking

A safety device your people actually wear.

Panic buttons only work if they are on the wrist when it matters. The Watch-1-LoRa shows the time, the date and messages from the control room — so it stays on, shift after shift, while GPS position and SOS alerts flow into 4MTracking over your own LoRa network.

Features & Applications

Key Features

Wide-area personnel safety on your own LoRa network — without a mobile contract per worker.

LoRaWAN without a SIM — positions and alarms travel over your own gateways straight into 4MTracking. No cellular subscription, no monthly cost per device.
One-touch SOS plus automatic alarms — a single button raises an emergency; geofence entry or exit, low battery and power-off alert automatically. Zones are drawn in 4MTracking and every crossing is recorded.
No dead zones — out of coverage the watch stores position and status on board and sends the backlog once a gateway is in reach; over 100 days of track history stay queryable.
Worn like a normal watch — 1.3" round touch display with time, date and messages from the control room; standard 22 mm strap in silicone, leather or metal.
10+ days on a charge — 450 mAh battery, contactless magnetic charging and IPX7 waterproofing for full-shift, all-weather use.
Optional health monitoring — heart rate, blood oxygen and body temperature plus wear detection, for heat stress, exhaustion and man-down situations.

Personnel Tag Watch-1-LoRa worn on the wrist — **On the wrist, all shift.** Familiar form factor, real display — the reason it stays on when a clip-on tag ends up in a locker.

Applications

Mining & Quarries

Personnel visibility across pits, haul roads and processing plant, with SOS in reach at all times.

Lone Workers

Staff working alone or out of sight — position, panic button and optional man-down indication.

Construction Sites

Wide outdoor sites covered by a handful of gateways; restricted areas enforced by geofence.

Security & Guarding

Patrol tracking with checkpoint reading via the optional RFID tag strap.
