# Relationship - Sensor Independent

**Relationship Sensor Independent** (or Frame-Level Relationship Creation) — now, relationships between objects only need to be defined once per frame, rather than separately for each sensor view. This streamlines multi-sensor annotation, ensuring consistency and saving valuable time.

{% hint style="success" %} <img src="/files/qchq9tcQpS8cX7YBw03I" alt="" data-size="line"> This feature is especially useful when working with multi-sensor setups like LiDAR + cameras AND all sensors of a frame, are **synced.**

## Benefits

* Simplifies annotation in multi-sensor environments.
* Ensures **consistency**, saves time by **reducing redundant work**.
* Maintains a single source of truth for object interactions across views.

## Steps to Use Relationship Sensor Independent

To enable [Frame-Level relationship](/project-setup/create-recipe/1.-basic-details.md#relationship-sensor-dependent) creation, it must be pre-configured in the Recipe.

1. Track both objects within the same frame across all relevant sensor views (e.g., `cyclist_3` and `bike_2`).
2. In the [Annotation Detail panel](https://docs.imerit-prod.io/annotation-tool/key-features/pages/rZkaXOIF73IyAuNXrSbe#id-6.-annotation-detail-input), navigate to the Relationships tab and define the relationship between the two objects.
3. Save the relationship to apply it across the entire frame.
   * The option to apply this relationship across the sequence will be prompted.

{% hint style="info" %}
When a relationship is created between two objects (e.g., a cyclist and a bike), it is **automatically applied across all synced sensors** of the same frame, and by choice - across the sequence.
{% endhint %}
