Cheap, can be widely used in home office anti-theft alarm. It is prone to interference from various sources of heat, sunlight, and radiation.
When the ambient temperature is close to the human body temperature, the detection and sensitivity decrease significantly, sometimes causing short-term failure. The biggest drawback of magnetron door and window alarms is that they have low technical content and are easily cracked. Therefore, they can only be used as daily burglary warnings, and are not suitable for theft prevention with more expensive items.
