The G7c is a robust connected safety monitor designed for real-time employee protection, lone worker monitoring, and gas detection across challenging industrial environments.

Real-time wireless monitoring and communication for enhanced worker safety.

The G7c from Blackline Safety is a feature-rich, connected safety monitor that utilises 3G cellular technology to maintain real-time communication between workers and monitoring personnel. It is built to automatically safeguard employees through incident detection and provide instant alerts and data analysis to ensure compliance and swift emergency responses.

Main Features

Integrated 3G cellular connectivity for real-time communication.
Automatic lone worker monitoring with fall and no-motion detection using tri-axis accelerometer and gyro.
Gas detection using customisable modular cartridges supporting single-gas, multi-gas diffusion, and pump configurations.
Live monitoring personnel can communicate via two-way speakerphone.
GPS and indoor location technology for accurate worker tracking.
Real-time data streaming and automated compliance analytics via Blackline Live and Blackline Analytics platforms.
Configurable employee check-in intervals and SOS alert functions, including silent and latch-activated options.
Push-to-talk communication, assisted GPS, and configuration modes to suit various environments.
