How many number of cameras you need and how much it will cost you?
For Example in Residential Surveillance system
Four cameras and 4 channel NVR with 1 TBB storage capacity is good for residential use.
Camera 1 – Covers main door
Camera 2 – Covers Driveway
Camera 3 – Covers Backyard
Camera 4 – Covers Side entry
How cost will change with number of cameras?
If you need 5 cameras in house then you need 8 channel NVR with 2 TBB storage capacity
With just addition of one camera , we need 1TBB extra storage capacity and 8 CH NVR instead of 4 CH.
