The specs show 120 volt only. Some power supplies can handle a higher voltage, but I would not risk it. Can your electrician locate a small 240-`120 transformer? I would think they are pretty common.
Or you can check with Wyze. But I think they would err on the safe side and say no.
The audio on one of them is not recording properly, I don’t know if that has to do with the voltage or something else though. The rest is working fine.
Stopped quite a few attempted burglaries on the car with the automatic alarm when it spots a person, and one conviction for the police from the recordings where someone tried unsuccessfully to get a bike, reported to police and they recognised the person.
