The face detection and recognition are bundled as default features in CloudCam.
Face detection is the process by which the camera detects presence of faces in the view. In case it finds faces in the view it alerts the cloud. These faces will be shown in your alerts dashboard along with other alert information. To start with these faces will be nameless. The camera needs to be trained to recognize these faces. This process starts when you provide a name to a face. Initially it will be inaccurate as there is not much training data. As you add names to more faces the camera starts naming the faces that it finds further in the field.
