The controller of claim 1 , wherein the controller generates self-diagnostic information related to features of the controller, the self-diagnostic information being selected from the group consisting of: information related to backlighting, information related to a sound-making device, and information related to data-access errors.
12. The controller of claim 1 , wherein:
the controller detects at least one communication-link problem over one or more networks in the electronic monitoring system; and
information related to the detection is included as part of the health information.
13. The controller of claim 1 , wherein the controller receives information related to brightness and verifies proper operation of a light sensor coupled to the pixel array via the received information.
14. The controller of claim 1 , wherein the pixel array comprises a plurality of light-emitting diodes (LEDs).
15. An electronic monitoring method, the electronic monitoring method comprising, by a controller of an electronic monitoring system, the controller comprising a processor and memory:
