Hi Beckie, the wireless security IP cameras won’t get your Internet access unless you use your phone or computer to connect to it and get live streaming remotely, or unless it detects burglars and sends video or images to you. So they use your Internet only when it’s necessary. Here are two recommended wireless security cameras for you: /product/rlc 411ws/, /product/rlc 410ws/. Or you may choose the wireless surveillance camera systems. They can offer the most comprehensive protection for your home and work best with internet access. Even without network, they can still do 24/7 surveillance and video recording. But note that you cannot get remote viewing or monition detection alerts without Internet. /product/rlk4 210wb4/Anything lower than these numbers may leave you squinting and trying hard to recognize what you’re viewing from the monitor. Of course, you would also want a recording angle that’s wide enough for a better coverage. If you’re getting a camera with revolving lens, get one with a 360 degree viewing angle. Otherwise, 120 degrees should suffice for a fixed lens.
