With this system, the cameras attach directly to your home network, either by WiFi or network cable. Some use PoE, which uses a special router to provide both power and internet connection in a single cable.

This is espically practical if you only need one or two camera but can get more costly than an NVR system when scaled up to four or more cameras.

Pros

  • Inexpensive for 1 or 2 cameras
  • WiFi models only need power cord

Cons

  • Use SD cards for storage -- limited time/space
  • SD card required for each camera
  • Wired cameras can use up all the ports on your router
  • Expanding to several cameras can get more expensive than a full system
