Three Key Design Considerations of IP Video Surveillance Systems
... In an IP-based system, video streams are converted to digital data and shared through the IP network. The benefits of IP surveillance are: Remote Accessibility: IP-based video encoders and IP cameras use an IP network to deliver the video stream, so as long as there is an access to the network, the ...
