Keyboard
— own keyboard that allows you to control the functions of the central unit directly from its body. To access such control, you need to be directly near the central unit, but in some situations this is not a disadvantage, but an advantage. In particular, if the design does not provide other control methods, except for the keyboard, remote hacking of the alarm becomes practically impossible, and in order to physically get to the central unit, usually, it is necessary to overcome the protected perimeter. In addition, this control method does not require sophisticated equipment and is inexpensive.
