Smart Person and Vehicle Detection

Smart person/vehicle detection is based on traditional PIR detection but with advanced algorithms and technology, which can tell people and vehicles from other objects. Also, our camera supports setting object size, which contributes to the reduction of false alerts.

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

Twin Lenses

While for Duo PoE, equipped with dual lenses, this camera provides you with a wide 150° field of view* with less distortion to protect your family.
