Triple-Lens Camera and Motion Detection
Triple-Lens Camera and Motion Detection
Another important subject connected with this type of camera is motion detection. Security cameras can analyze changes in the image and identify movement within selected areas. When movement is detected, the system may trigger recording, send an alert to a connected phone or monitoring system, or cause the PTZ camera to focus on the area. The multiple lenses can make motion monitoring more useful because movement can be observed from different viewing directions. However, motion detection is not the same as perfect identification: environmental movement such as trees, insects, changing light, or passing vehicles can sometimes produce false alerts depending on the camera's settings.
