# Tow detection

Detects unauthorized movement of a parked vehicle using the device's built-in motion sensor. After the ignition is switched off, the sensor arms and monitors for vibration, impact, or movement. If movement is detected, the device sends an event to the Navixy platform, which can notify you via [Rules and notifications](/docs/user/guide/events-and-notifications/security/unauthorized-movement.md).

## Settings

* **Enable or disable**: Turn tow detection on or off.
* **Sensitivity**: Motion sensor sensitivity, for example high, medium, or low, where a lower value is more sensitive.
* **Delay after engine off**: How long after ignition-off before detection arms.
* **False-alarm (fake-tow) delay**: A short delay that filters out brief movements so they don't trigger a false tow event.

## Availability

Appears on devices that support tow detection (vendor variants exist, e.g. Queclink, Teltonika).

## Limitations

* Set sensitivity carefully to avoid false alarms. Accuracy depends heavily on correct installation and varies by model.
* This is device-side detection. It's related to, but distinct from, the platform-side [Unauthorized movement](/docs/user/guide/events-and-notifications/security/unauthorized-movement.md) rule and the other [anti-theft and security](/docs/user/guide/devices-and-settings/device-specific-controls/anti-theft-and-security.md) modes.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://navixy.com/docs/user/guide/devices-and-settings/location-and-movement/tow-detection.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
