What are the Remote Access Options for CathexisVision VMS?


Solution


Unfortunately most video surveillance systems are firewalled and blocked from direct access to


the public Internet.


There are 5 Remote Access Options for Video Surveillance


  1. Port forwarding


  1. Universal Plug and Play (UPnP)


  1. Dynamic DNS


  1. Virtual Private Networks (VPNs)


  1. Cloud / 'Phone Home' (e.g., Axis AVHS, Dropcam)


Port forwarding (Option 1) assumes the use of a static public IP address, but you can always make use of Dynamic DNS (option 3) to get around this.


You can also make use of your own VPN connection (option 4) in order to to connect to your recoder.


We do not support the following:



Option 2: Universal Plug And Play


Universal Plug and Play (UPnP) is a set of protocols which automate device


discovery and configuration on a local network. One of the aims of UPnP is


eliminating manual port forwarding (above), allowing a UPnP device to


automatically create port mappings in a router without any intervention from the


user.


However, in practice, UPnP is unreliable in many cases. In many business


networks, large and small, UPnP functions are turned off, requiring manual port


forwarding. In consumer use, port mappings may not function properly, may be


added more than once, may conflict with other devices, or may simply not be


added at all. Making things worse, error information is rarely available when


UPnP port mapping fails, leaving the user without any means of troubleshooting.


Because of these reasons, manual port forwarding has proven more reliable in


commercial surveillance, with UPnP typically left to consumer use.



Option 5: Cloud / 'Phone Home'


To eliminate the complexity and potential for errors involved in manual port


forwarding, UPnP, and Dynamic DNS, cloud connections have become more


prevalent. Cloud connections are a form of VPN (sometimes called application


specific VPNs) which requires limited or no user interaction to configure.


Dropcam and Axis AVHS are two prominent examples of this approach.


Cloud connections are generally made via a secure TLS (transport layer security,


an encryption protocol) tunnel, set up via these basic steps (noted on the image


below):


  1. Initiating device sends a HELLO message to request a connection.


  1. Server sends HELLO along with a security certificate.


  1. A handshake is performed and a secure tunnel is set up.


  1. Once the TLS tunnel is in place, data sent through it is encrypted, with


protocol and data specifics obscured (shown only as "application data" in


the example below).
