Person and vehicle smart motion detectionThis NVR supports cameras that feature advanced person and vehicle detection on up to 8 channels which helps identify more important objects that enter the camera's field of view. Thanks to this innovative feature, you will only get a push notification and image screenshot to your Lorex Home app whenever a person or vehicle is detected on your property. This effectively reduces the number of unwanted false alerts caused by moving branches or animals. All recorded motion alerts can easily be reviewed by using the Smart Search function in the Lorex Home mobile app.Compatible with Active Deterrence Cameras This NVR works with select active deterrence cameras. This means you can add cameras that feature both motion-activated LED warning lights, which can be customized to be manually activated, triggered by motion or always on, and a remote-triggered siren that you can control from your Lorex Home app. When the camera sensors detect motion, the system will send a notification directly to your phone, allowing you to remotely access the camera and set off a loud warning alert.
