I bought this system a few years ago. Never opened, never installed.
Per the box:
It is an 8 channel / 4 camera setup.
500 GB Hard Drive (over 2500 Hrs of Recording Capability)
Mobile Phone and Web Surveillance
Includes 4 Indoor/Outdoor Color Cameras with Infrared Night Vision
Continuous, Motion Activated and/or Scheduled Events.
That is about all I know about this system. I recall that I paid around $300 when I bought it.
I do know that it is a wired system.
