A system is disclosed for sensing selected conditions particularly for an unoccupied commercial business and taking the appropriate action. Corrective action may include shutting down a system, sending a signal to an occupied location for evaluation of the selected abnormal condition, making a record of the abnormal condition for rectification at a later time. The system includes one or more light level sensors directed to observe the light level at a selected location, a CPU or controller which stores data representing acceptable light levels and a schedule. If the light level at the selected area does not reach or maintain the desired light level, corrective action is taken. If the commercial establishment is a bank and the light level is at an ATM (automatic teller machine) the system may temporarily shut the ATM machine down and illuminate a sign to indicate that the ATM is not open. If the sensor is directed toward or monitors non-essential lighting, for example, signs, it may merely record the insufficiency in lighting and produce a record for later correction of the condition. If the condition sensed is a different type of discrepancy, failure of heating, water leak detection or other emergency, the system includes a modem and telephone communications link to a human monitoring station for instantaneous alerting and to allow corrective action.
