A:AnswerAs long as you can successfully install the drivers into your desktop or laptop computer, the software application that comes with the driver will show what signals are available. 2.5G or 5G signals. Wifi itself is standardized so it will work regardless of country.
A:AnswerNo it is not. My computer also doesn’t have a CD drive but I do have an external one. It would be worth to get a simple external CD drive to not only install this product, but other things in the future.
A:AnswerSure. Install/Place adapter a bit further from your router & closer to your security system. It should connect to your router and serve as an access point for your security systems, if the cameras can’t pick up WiFi signals from a long distance.
