GENERAL QUESTIONS ON WIRELESS WIRELESS-TX-RX
- Do your cameras work with different voltage for other countries?
- Most of our cameras come with a power adapter that can handle form 110V ~240V AC. In case you get a camera with direct AC plug-in such as clock radio camera we will include the 220V to 110V (60Hz) step-down converter. However, if your country uses 50Hz, the time on the clock, because it is digital, will not be correct (it will be off about 20 min a day)
