What is VNC?

September 2022

VNC stands for  Virtual Network Computing  and is a cross-platform screen-sharing system that uses the Remote Frame Buffer (RFB) protocol. VNC was created to control another computer remotely. You may know it best for its role in tech support services.

VNC works on a client/server model. A VNS server component is installed on a remote device (the device you want to control), and a VNC client (also called a viewer) is installed on the local device you use to connect to the remote device. Either device may be a computer, a tablet, or a mobile phone. When the server and viewer are connected, the server transmits a copy of the remote device’s screen to the viewer.  

Not only can the remote user see everything on the remote computer’s screen, but the program also allows for keyboard and mouse commands to work on the computer remotely, so the connected user has full control (after being granted permission from the remote computer).  

Industries & Use Cases

  • The most popular industries for VNC use include:
  • Information Technology and Services
  • Consumer Transactions
  • Financial Services
  • Computer Software
  • The Internet of Things (IoT)
  • Consumer Electronics
  • Manufacturing
  • Fleet Management
  • Hospitals & Healthcare
  • Remote Video Monitoring (Security Industry)

Mostly known for assisting users in customer service, such as in tech support scenarios, VNC has many other helpful uses in the financial industry, hospitals and healthcare, computer software, and more. 

While CrossLink Basic can add HTML web pages to the Ganz CORTROL's video management system  as an interactive channel, Crosslink Advanced offers a VNC Client to VNC server connectivity. In addition, Crosslink Advanced can record the channel hosting the remote desktop session, a vital function where the operator’s interaction with a remote desktop needs to be audited. Crosslink Advanced channels can also be sent to video wall displays in the CORTROL VMS Global edition. Learn more about CORTROL Crosslink here .

Watch the video below to see how it works. Please note the target client PC must be running the VNC service for our VMS to connect.

VNC has multiple uses in various industries, the most common being technology. It is instrumental in Video Management Systems such as our  Ganz® CORTROL VMS for recording channels.
