I want to buy some CCTV cameras and I'm wondering if I can get an internet enabled one and access it from my own computer/iPad/phone only over wifi? Is this possible? Or does it have to be connected to the internet?
You should be able to access it over WiFi, and most require you to set them up via a local network. To disable internet viewing, you simply block the IP from outside access (use a static IP for the CCTV). Your system you purchase should have instructions for that. – Jeff Cates 2 days ago
