I have a customer, that currently has a little over 50 cameras at his company's headquarters, and wants to bring his surveillance system up to date. That being said, all cameras are analog w/ two power supplies, 3 dvrs and was told that he needed three ISPs lines to support the system. I know that there's at least 3 different brand of cameras that are installed both inside and out. I am attempting to use the calculator for building's covered perimeter walkway. The question I have with the calculator is what to do when there isn't a "street view" available(specifically being able to see the best location for the camera/camera's FOV, thus enabling me to narrow down the camera options. If it would help, I can post the site plan.
Thanks!
