Cable Theft Monitor

RLB Group Cable Theft Monitor Solution (powered by Polygon Technologies CTM001 & GSM Commander), exclusively distributed in Zimbabwe by RLB Group, is a robust, African-engineered anti-theft system designed to combat the escalating problem of cable theft and vandalism.

This issue severely affects agriculture, mining, utilities, telecom, manufacturing, and critical infrastructure across Zimbabwe. In a country where power outages, water supply disruptions, and communication failures are often linked to stolen copper cables, RLB Group’s solution provides proactive, reliable detection for both live (energized) and dead (unpowered) cable runs up to 600Vac.

Core Operating Principle

RLB Group’s Cable Theft Monitor employs a hybrid monitoring system combining voltage sensing, DC signal reflection, and optional complementary sensors. This delivers dependable performance in Zimbabwe’s varied conditions.

Step-by-Step Detection Process

1. Standby Mode: While AC voltage is present, the system remains in low-power standby.
2. Power Loss Trigger: Activates instantly upon detecting AC voltage loss.
3. DC Signal Injection: Injects a specialized low-voltage DC signal and monitors reflection.
4. Alarm Activation: Switches output from Normally Closed to Open upon cable cut or tampering.
5. Notification: Integrates with GSM Commander for SMS, calls, and app alerts.

Key Features

• Works on both live and dead cables (up to 600Vac)
• Fast detection even during load shedding
• Fail-safe Normally Closed output
• Low power 12V DC operation — ideal for solar systems
• Full integration with GSM Commander for remote monitoring
