CCTV (Closed Circuit Television) systems use cameras to capture video footage, which is then transmitted to a monitor or a recording device.
The cameras send the information on the data it captures to the DVR or NVR. The video record then:
- transmits the information to the screen
- records the information on the hard disc
- connects to a router which broadcasts it across the web
This broadcasting is what allows you to access your feed from any computer, iphone or android device.
