This project is an attempt to create a peer-to-peer video monitoring system for Android devices primarily and any other clients implementing the protocol in the future. Any camera enabled Android device may run as a server (p2pcamera app) to accept connections from clients (p2pmonitor app for Android) and stream media data to them. Protocol implies a possibility for clients to control server part requesting available features and managing the camera parameters as if it was local.

##Source code and building The project contains compile-time annotations. While source code gets built without errors, you may find unresolved references during source code overview. In order to eliminate such faulty error highlights consider installing bali-intellij-plugin (an evolution of lombok-intellij-plugin which supports Enum annotations used in this project)
