If you're looking for more than 3 cameras, you're best off looking at a DVR system. This is comprised of 4 or more cameras hooked to a central recorder box containing a large hard drive.

Pros

  • One point of internet connection
  • One point of viewing and recording
  • Only needs one storage device for all cameras

Cons

  • DVR should be in accessible place which can make for complicated wiring
  • No redundancy - If central box fails, all cameras go out
