Why does the monitor flicker after turning on the LED lamps?
Good day! Please tell me what is the reason for the flicker of the PC monitor of the video surveillance system after turning on the 220 volt LED lights to illuminate the perimeter of the building at night.
In general, this can be caused by interference from the lamps. Try connecting your computer through a quality surge protector.
With the permission of Alexei, I will try to offer my answer to the question of Mikhail. Perhaps the whole thing is in the so-called stroboscopic effect. The fact is that some low-cost LED lamps flash at twice the network frequency (100 Hz). This is due to the manufacturer’s saving on the quality of the lamp power supply. The eye does not notice flicker with such a frequency. But if you look at such a lamp through a smartphone in camera mode, then flicker will be visible. This flicker, apparently, is observed by Mikhail on the monitors of the video surveillance system. You can advise Michael to replace flickering with better flicker-free lamps, which can be selected when buying using a smartphone as described above.
