Multiple cam packages aren't that much more expensive. The best is one that not only stores up to the cloud, but has 2 way audio, motion detection and a mobile device app.
The homeowners obviously did their homework and located them to provide an angle for positive facial recognition, except if the bad guy had a ski mask on. Too many businesses have the camera angle and resolution such as it's difficult to positively ID them. Ever see those vid clips of a robbery of a gas station where they ask for help finding the bad guy and you couldn't tell them from a neighbor kid?
Based on my apartment I only need my 1 fixed cam set to the door to cover a crouch or a 7 ft. person, 2 way audio and mobile app so that if it triggers when I've enabled it I can view and say to them "Hey azzhole, I see you, leave now!"
I haven't had to use it, low crime area, but peace of mind.
