Choosing a tracker isn't only about the monthly fee — the physical device type changes how it's installed, how tamper-resistant it is, and how long it lasts. Here's how wired, wireless and OBD-plug trackers actually compare.
Hardwired directly into the vehicle's electrical system, typically at the battery or ignition. Power draws from the vehicle indefinitely, installation is completely hidden from view once done, and this type is generally the hardest for a thief to locate and disable — the most common choice among professional installation services.
Run on an internal rechargeable battery and use cellular networks to transmit location, so they can be placed anywhere in the vehicle with no wiring. Installation is DIY with no tools needed, but battery life runs roughly 1–3 years depending on usage before it needs attention.
Plug directly into the vehicle's OBD-II diagnostic port, usually under the dashboard. Installation takes seconds and the device draws power from the vehicle, but it's visibly plugged in and relatively easy for a thief to spot and unplug.
| Feature | Wired Trackers | Wireless Trackers | OBD Trackers |
|---|---|---|---|
| Installation | Professional, 1–2 hours | DIY, minutes | Plug-and-play, seconds |
| Power source | Vehicle battery | Internal battery (1–3 years) | OBD port (vehicle power) |
| Visibility | Completely hidden | Can be hidden | Visible under dashboard |
| Security level | Highest | Medium | Lowest |
| Tamper resistance | Excellent | Good | Poor |
| Additional features | Immobiliser integration | Geofencing, movement alerts | Vehicle diagnostics |
| Cost | Higher upfront | Moderate | Lower upfront |
| Best for | High-risk areas, premium vehicles | Rental fleets, occasional use | Teen drivers, basic tracking |

You want maximum theft security, own a high-value vehicle, live in a higher-crime area, don't mind professional installation, or want integration with an immobiliser.
You need a temporary or portable solution, want to avoid professional installation, need to move the tracker between vehicles, or your vehicle is older and lacks an OBD-II port.
You want the simplest possible installation, need vehicle diagnostic data alongside location, are monitoring a teen driver or an employee, or want the lowest-cost tracking option and have a post-1996 vehicle with an OBD-II port.
While OBD and wireless devices are convenient, professionally installed wired systems from reputable providers generally offer the strongest protection against determined theft attempts in South Africa's higher-risk environment.
This page covers the physical form factor — how the device is fitted. A separate question is which underlying signal technology it uses to actually locate the vehicle. See our GPS vs RF trackers guide for that comparison.
Wired trackers connect directly to the vehicle's electrical system, giving continuous power but requiring professional installation. Wireless trackers run on their own battery, which makes them easier to fit but means they need periodic recharging or a battery swap.
Generally no. OBD trackers plug in visibly under the dashboard and can be spotted and unplugged fairly easily. Wired trackers are hidden within the vehicle's electrical system during professional installation, making them much harder to find and disable.
It's technically possible but not recommended. Incorrect wiring can damage the vehicle's electrical system, void a warranty, or leave the tracker malfunctioning exactly when you need it most — professional installation is the safer route.
Many insurers require a professionally installed wired tracker for comprehensive coverage on higher-value vehicles, since it offers the strongest security. Always check your specific insurer's requirements before purchasing.
