The Ez Tracker function allows users to control the speed dome camera through the fisheye camera web user interface. This function can be easily operated using a mouse. Click a desired location on the 360° surround view from the fisheye camera and the speed dome camera will be exactly triggered to track that location. Users can then utilise the smooth PTZ function on the speed dome camera view to zoom in or focus on a region of interest. Meanwhile, users can also monitor all the movements from the 360° surround view.

The Everfocus EFN3320 is a 3-megapixel fisheye camera designed to monitor a location with 360° surround view (ceiling / desk mount) and 180° panoramic view (wall mount). The fisheye camera provides up to 8 cropped regions of view with changeable angles, allowing users to monitor all angles of a location simultaneously using just one camera. Everfocus EPN series of network speed dome cameras support up to 30x optical-zoom and can offer real pan/tilt/zoom function for detailed and smooth video images. With these features, users can lessen the expense on surveillance system set up, such as cutting the number of cameras, reducing manpower costs and decreasing maintenance fees.
