A:AnswerNo, you can not view both cameras at once. And as far as viewing more than one angle, that would be a no. Wherever you set or place the camera, it will practically cover a room except for the area the camera is setting or hanging.
A:AnswerThere's a possibility, but I'm not totally sure. On the monitor it does have a set-up for camera #1, #2, #3, and #4. So I would assume you probably could order more from the company.
