Typical Use Cases

• Stolen Vehicle Recovery (SVR): The 433MHz RF transmitter enables detection inside car parks, buildings, and areas where GPS signals are attenuated — making the GL533CG the ideal SVR companion device for fleet and high-value vehicles.

  
  

• Long-Term Container Monitoring: With up to 4 years of battery life, the GL533CG can be installed on shipping containers and forgotten — reporting at low frequency for years without maintenance.

  
  

• Trailer Fleet Management: Track trailer locations across the network and receive alerts when trailers are moved without authorisation, helping reduce theft and misuse.

  
  

• Construction Equipment Security: Bolt the GL533CG to excavators, generators, and tools to monitor their location across job sites without wiring to vehicle power.

  
  

• Agricultural Machinery Tracking: Deploy across tractors and farm equipment that spend months stationary — the battery endurance means no maintenance visits required.

  
  

• High-Value Asset Monitoring: Track expensive assets in transit or storage with tamper alerts ensuring you know immediately if the device is interfered with.

  
  

• Cargo Security in Transit: Monitor cargo movement across road networks with motion-triggered reporting and tamper detection for sensitive shipments.

  
  

• Emergency Response Assets: Attach to ambulances, generators, and emergency response equipment, with the SOS button providing manual alert capability for field operators.

  
  

• Cold Storage Monitoring: Track refrigerated trailers and cold storage containers across the supply chain within the device's -20°C to +60°C operational range.

  
  

• Quarry and Mining Equipment: Rugged IP67 construction and long battery life make it suitable for heavy plant equipment in harsh open-cast and underground environments.

  
  

Frequently Asked Questions

What is the purpose of the 433MHz RF transmitter in the GL533CG?

The 433MHz transmitter is designed for SVR (Stolen Vehicle Recovery) applications. When a stolen vehicle is inside a car park or building where GPS signals are blocked, specialist recovery teams use 433MHz RF detection equipment to locate the device — significantly improving recovery rates over GPS-only trackers.

How long does the battery last in the GL533CG?

On 3×CR123A primary (non-rechargeable) cells the GL533CG achieves up to 4 years of standby at 1 report per day. Higher reporting frequencies will reduce battery life. The use of primary cells means no charging infrastructure is required.

Is the GL533CG waterproof?

Yes — the GL533CG carries an IP67 rating, meaning it is fully protected against dust ingress and can withstand immersion in up to 1 metre of water for 30 minutes. It is suitable for outdoor deployment on vehicles and equipment in all weather conditions.

Which regions is the GL533CG compatible with?

The GL533CG is certified for use everywhere except North America. It covers Europe, the Middle East, Africa, Asia-Pacific, and Latin America with its LTE Cat 1 band configuration (B1/B2/B3/B4/B5/B7/B8/B20/B28) and EGPRS 850/900/1800/1900 MHz fallback.

Can the GL533CG detect tampering or unauthorised movement?

Yes — the GL533CG includes both tamper detection and motion detection. Tamper alerts fire when the device housing is interfered with, while motion detection triggers immediate reporting when the asset starts moving unexpectedly — providing two layers of security alerting.
