Hub 2 Plus is a central device in the Ajax system, which controls the operation of all connected devices and interacts with the user and the security company. The hub reports the opening of doors, breaking of windows, threat of fire or flood, and automates routine actions using scenarios. If outsiders enter the secure room, Hub 2 Plus will send photos from MotionCam / MotionCam Outdoor motion detectors and notify a security company patrol.
