Adding network surveillance cameras to an existing Ethernet network

A: Is not recommended, since bandwidth demands from the surveillance video would likely congest the network. B: Will benefit from using VLANs, to keep the surveillance video separate from other network traffic, reducing the risk for network congestion. C: Will cause unacceptable video latency, due to the amount of UDP traffic taking precedence on the network. D: Will benefit from establishing VPN connections to the cameras, reducing the risk of malicious users eavesdropping on the video.
