The present invention provides a non-contact monitoring system, including: a radar detection module, an infrared sensing module, a micro control unit and a communication module. The radar detection module transmits a radar detection signal via the radar antenna to an area, receives a radar reflection signal from the area, and transmits the radar reflection signal to the micro control unit. The infrared sensing module detects a heat source of an organism in the area, and transmits an infrared sensing signal to the micro control unit. The micro control unit receives and processes the radar reflection signal transmitted by the radar detection module and the infrared sensing signal transmitted by the infrared sensing module, and transmits an alarm signal to the communication module. The communication module receives the alarm signal transmitted by the micro control unit, and transmits the alarm signal to a remote monitoring end via the antenna.
