Smart Person and Vehicle Detection

The Smart Person or Vehicle Detection is based on the traditional motion detection but with advanced algorithms and technology, which can tell people and vehicles from other objects.

You can set this function on the reolink app or the reolink client.


Auto tracking uses advanced technology that consists of both detection and tracking. The camera will automatically detect, follow, and even record a specific vehicle or person in the cover area.

For how to set up this function for the camera, please refer to the below guide:

Preset and Cruise

A Preset is a user-defined position of the camera‘s pan tilt and zoom settings. Creating camera presets in advance can allow it to go to the wanted monitoring positions easily.

Cruise means that you can specify the scanning route of the camera through a set of presets. The camera will scan according to the preset cruising speed and staying time.

You can set this function on the reolink app or the reolink client.


A camera with an audio alarm or siren can make a loud prolonged sound as a signal or warning when the camera detects motion alarms.

You can set this function on the reolink app or the reolink client.


When an alarm event is detected, it will be automatically turned on, and the spotlight can also add light sources to produce full-color images.

By default, the Night Mode is set as Auto.
