MONITORING CAMERA DEVICE, DEHUMIDIFYING DEVICE, DEHUMIDIFYING METHOD AND DEHUMIDIFYING PROGRAM

摘要

A monitoring camera device (1) is provided with a camera case (2); a dehumidifying element (3) arranged in the camera case (2); a current value detecting section (8) for detecting the current value of the driving current of the dehumidifying element (3); a target current value determining section (10) for determining a target current value (It) based on a first current value (I0) detected at a period start time (t0) of a prescribed current change judging period and a second current value (I1) detected at a period end time (t1); and a voltage control section (13) for controlling the driving voltage of the dehumidifying element (3). Dehumidification of a target dehumidifying quantity (S) is performed for the camera case (2) until the target time (t2) by driving the dehumidifying element (3) until the target time (t2) at a target current value (It). Thus, the monitoring camera device (1) wherein dehumidification can be performed in a short time when the humidity inside the camera case (2) is high is provided.
