Signal strength changes based on where the device is installed. Metal parts can block satellite communication and reduce accuracy.

Trackers under thick metal may lose GPS connection. The roof area usually provides the strongest signal.

Optimal signal locations include:

• Wheel wells with a clear sky view
• Rear bumper edges
• Beneath plastic body panels

Distance from electronic components matters. The engine bay contains devices that can interfere with GPS signals.

Radio frequencies and ignition systems can disrupt signals. Placing the tracker away from these sources improves performance.

Concrete structures and underground parking can also affect signal quality. Trackers in exposed locations reconnect faster after signal loss.

Importance of Concealment for Security

Hidden placement helps prevent detection by thieves. Visible GPS trackers are easier targets for removal.

Professional criminals often check common tracker locations. Obvious spots reduce the effectiveness of your security system.

High-risk visible areas to avoid:

• Dashboard surfaces
• Center console areas
• Exterior bumper faces

Concealment must be balanced with signal access. The tracker needs to be hidden but still able to connect to satellites.

Internal locations offer better concealment but may reduce GPS performance. External hidden spots can provide stronger signals if camouflaged well.

Weather protection is important for outdoor installations. Moisture and temperature extremes can damage exposed trackers.

Role in Preventing Tampering and Theft

Secure mounting protects the GPS tracker from being removed or damaged. Easy-to-reach positions can invite tampering.

Strong magnetic attachment keeps the device in place during movement. Flat, clean metal surfaces offer the best magnetic grip.

Secure mounting characteristics:
