IoT Fog-based Image Matching Monitoring System for Physical Access Control through IP Camera Devices

Many people are concerned with physical security and seek support from resources provided by the latest technological advancements, such as security cameras with Internet access associated with biometric people recognition algorithms. However, an isolated camera has a low degree of effectiveness because it has a limited context of information. For instance, detection of missing persons is only effective if multiple cameras are aware of that person is missing. This work proposes a command and control center to allow the coordination of security cameras in a remote and flexible way. This flexibility is achieved because the user can remotely register the actions that each camera must perform, even with the system in operation. It also allows the sharing of a user's information with multiple cameras. Our tests demonstrate that the system can be installed in an environment with few computational resources, as well as it reacts properly according to the configured parameters.
