mmWave Fall Detection Sensor Documentation

Hi, In the documentation for setting up mmWave Fall Detection Sensor (Link to doc), in the Hardware overview section, there’s a caution alert note that reads: “The power consumption of the product is 500mW, which is not suitable for long-term power supply.”

I’m not exactly sure what that means. Does that mean you shouldn’t use the sensor to power other things? Or does that mean you shouldn’t have the sensor plugged in for long periods of time?

Thanks in advance!
