Smart Detection, Secured Home
By analyzing the shapes of people, vehicles, and pets, RLK8-811B4 can precisely detect these objects. It brings you peace of mind by providing accurate real-time alerts and reducing false alarms.
Double Warning for the Unwelcome
Once an intruder is detected, the camera's spotlights and siren will be triggered or manually activated to warn off the would-be criminal. Stop the crime before it happens.
Two-Way Talk
Built-in mic & speaker allow you to listen and talk back to whoever the camera catches in real time: A "hello" to families and friends or a warning to suspicious strangers.
*Note: This function is only available in Reolink App/Client.
