"GPS tracker" and "RF tracker" both get sold as vehicle security devices, but they work on completely different technology — one uses orbiting satellites, the other uses a network of ground-based radio receivers. Here's what each actually does, how they compare on coverage, accuracy and cost, and when one makes more sense than the other.
GPS (Global Positioning System) trackers use a network of satellites orbiting the Earth to determine precise location coordinates through triangulation. The device then connects to a cellular network — in South Africa, typically MTN, Vodacom or Cell C — to transmit that location data to a monitoring centre or app. Because it relies on cellular coverage, GPS tracking works nationwide wherever there's signal, with real-time updates and accuracy typically within 5-10 metres.
RF (Radio Frequency) trackers use dedicated VHF radio signals instead of satellites or cellular networks. A small transmitter is hidden in the vehicle, and a network of ground-based receivers — operated by the tracking company, often concentrated in higher-risk urban areas — picks up its signal. RF tracking doesn't depend on cellular coverage at all, and its signal is extremely difficult for a thief to detect or jam, though its accuracy (typically 100-500 metres) and coverage depend heavily on receiver density in a given area.
| Feature | GPS Trackers | RF Trackers |
|---|---|---|
| Coverage area | Nationwide (with cellular coverage) | Limited to zones with receivers |
| Location accuracy | 5-10 metres | 100-500 metres (receiver-dependent) |
| Real-time tracking | Yes, continuous | Limited to when the vehicle passes a receiver |
| Monthly cost | R50 - R200+ | Often bundled into insurance discount |
| Theft detection of the device | Can be found with an RF scanner | Extremely difficult to detect |
| Network dependency | Requires cellular network | Independent receiver network |
| Extra features | Geofencing, driver-behaviour data, maintenance alerts | Primarily focused on theft recovery |
| Best for | Fleet management, real-time monitoring, nationwide coverage | High-theft areas, insurance compliance, covert tracking |

Device cost typically runs R800-R2,500, with installation around R300-R800 and a monthly subscription of R50-R200. Insurance discounts for GPS-tracked vehicles are usually in the 5-15% range, and contracts commonly run 24-36 months.
Device cost is generally higher, R1,500-R3,000, with installation around R500-R1,000. The monthly fee is often included in an insurance arrangement rather than billed directly, and the associated insurance discount is typically higher, in the 15-30% range.

GPS is generally the better fit — real-time monitoring, route optimisation and driver-behaviour data all depend on continuous location updates that RF can't easily provide.
RF tracking offers strong covert protection precisely because it's hard to detect, and many insurers reward it with a larger premium discount in these areas.
RF's effectiveness drops where receiver density is low, so GPS (ideally with good cellular coverage on your usual routes) tends to serve remote travel better.
A hybrid system combining GPS and RF gives real-time tracking plus the covert backup of RF, at a higher combined cost than either technology alone.
GPS trackers use satellite signals for location data and cellular networks for data transmission, offering nationwide real-time tracking wherever there's cellular coverage. RF trackers use dedicated radio-frequency receiver networks instead, providing covert tracking within specific coverage zones without depending on cellular signal.
GPS is generally more precise, typically accurate to within 5-10 metres. RF accuracy depends on receiver density in the area and is usually in the range of 100-500 metres, though RF signals are extremely difficult for a thief to detect and jam compared to GPS.
Yes, many owners of high-value vehicles opt for a hybrid or dual system, combining real-time GPS tracking with the covert security of an RF device. This comes with higher upfront and potentially monthly costs than either technology alone.
GPS systems typically run R50-R200+ monthly with R800-R2,500 device costs. RF systems often have higher device costs (R1,500-R3,000), but the monthly fee is frequently bundled into an insurance discount rather than billed separately, and RF tends to unlock a larger insurance discount overall.
