Which motion detection system uses radio waves to detect motion?

What would cause LEDs to flicker? But most commonly, LED bulbs may flicker or dim in your home when there are voltage fluctuations in your home’s wiring. When electrical loads turn on and off in your home, this creates a change in voltage levels, which may cause the LED lights to occasionally dim or flicker.
How do you find the source of flickering lights? On a standard, 120-volt circuit, your home should have a reading of between 115 volts and 125 volts. If you have a voltmeter, you can check that reading yourself. If it comes back higher than 125 volts, that could be the reason your lights are flickering.
