Advanced motion detection

Be aware whenever motion is detected on your property with advanced motion detection. This system features person/vehicle detection on 4 channels which helps reduce unnecessary alerts and false alarms from moving branches or animals. Important motion events that are recorded can easily be found using the Smart Search feature, which organizes events by type (e.g. person/vehicle motion vs. general motion, etc.).
