Remote Network Access for Video Surveillance

Author: Ethan Ace, Published on Mar 13, 2017

Remotely accessing video is difficult for 3 reasons.

  • Private Networks: Almost all video surveillance uses private IP addresses, that are by definition, not accessible directly over the public Internet.
  • Firewalled: Most video surveillance systems are firewalled and blocked from direct access to the public Internet.
  • Dynamic Addressing: Many home, small business and remote locations use dynamic public IP addresses, so even if you could reach the private network through the firewall, the risk remains of the public IP address changing and disrupting access.

Five Remote Access Options for Video Surveillance

In this report, we explain how the five most common remote access options for video surveillance work:

  • Port forwarding
  • Universal Plug and Play (UPnP)
  • Dynamic DNS
  • Cloud / 'Phone Home' (e.g., Hikvision EZVIZ, Axis AVHS, Nest Cam)
  • Virtual Private Networks (VPNs)
