The Hub comes in 3 different versions
The choice of which of these 3 you need is determined by the number of detectors you want to pair, and the desire to add visual alarm verification capabilities.
In other words: Whether you want to purchase detectors with a built-in camera, such as the AJAX MotionCAM.
The AJAX Hub has a battery that provides up to 16 hours of backup, and in the event of a power failure, the alarm notification is immediately sent to the user.
