# Tow detection

Configure tow detection sensitivity and delay so the device triggers an alert when a parked vehicle moves without the ignition on.

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.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

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

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
