FIG. 7 shows the control unit 10 and wall-mount casing or housing 30 as they might appear when mounted on a wall. Here the key pad 12 is shown surrounded with visible indicators which may light up to guide the user in controlling the associated home security system, as well as conducting other functions. As a component of the user's home-based IoT, the unit 10 may also be used for locking and unlocking doors, turning lights on and off, or controlling temperature set-points of an associated thermostat. The design of the casing or housing does not interfere with any of those functions, which may be controlled either by pressing on the keypad 12 or by voice commands. Gestural commands may be possible in the near future.

FIG. 8 shows the rear or base wall 42 of the main housing component 32, with a channel or vertical cutout 44 extending from the cord opening 39 at the top down to the bottom of the base wall 42. This permits the power cord 22 (not shown here) to extend down from the housing to an available wall outlet below the position of the housing 30 and control unit 10. Alternatively, the base wall could have a tunnel or channel elsewhere, either on the back or on the inside, as a matter of design choice.

FIG. 8 also shows the position of four screw holes 46 for attachment to a wall. There could be more or fewer holes, or other structure provided to permit the casing or housing 30 to attach to a vertical surface.
