PURPOSE: To provide the terminal euqipment for a heat ray sensor in a remote monitoring control system where a detection area and a detection level are freely set and changed.

CONSTITUTION: The terminal equipment for the heat ray sensor uses a heat ray area sensor 11 and a heat ray emitted from a human body is condensed on the light-receiving surface of the heat ray area sensor 11 by a lens for heat ray 17 to form a heat ray image. An analog processing part 12 compares sensor outputs of the respective divided detection areas in the heat ray area sensor 11 which the detection levels of the respective detection areas, which are stored in a nonvolatile memory 13, to output a signal of detection in the detection area to a control part 14 when the sensor output exceeds the detection level. The nonvolatile memory 13 stores set data in the detection area and such set data as the detection level, and the stored set data is transmitted from an external function setting equipment 15 with an optical signal.
