The invention relates to the technical field of monitoring equipment, and discloses a monitoring device and a method for a closed space, and the device collects a visible light video and a thermal infrared video of a target monitoring area through a visible light camera module and an infrared camera module respectively, and displays the visible light video and the thermal infrared video through a display module. Video decoding processing is carried out on the visible light video and the thermal infrared video to obtain a visible light video frame image and a thermal infrared video frame image, temperature calibration is carried out on the thermal infrared video frame image through the monitoring management module to obtain a temperature distribution result. The temperature distribution result is compared with a preset temperature threshold value, so that a temperature comparison result is obtained. An alarm area with the temperature exceeding a preset temperature threshold value is marked in the thermal infra
