The Death of VNC
Say goodbye to conventional VNC (Virtual Network Connection) technology. RGB Spectrum’s new Video Desktop Adapters (VDAs) offer a superior remote desktop solution for security, oil & gas, audio-visual and educational applications.
RGB Spectrum’s high-performance VDATM technology offers a number of distinct advantages over VNC:
- Better image quality with clear, sharp text & graphics
- Full-motion high-definition video (up to 2x faster frame rates)
- Responsive keyboard/mouse control
- Enhanced security (AES-256 encryption and NSA Suite B cryptography)
Traditional VNC systems provide a basic level of remote desktop functionality. For simple applications, a VNC remote desktop might be adequate. If you need to view streaming video in real-time, however, VNC fails to provide the image clarity and responsiveness required for graphics and video-intensive applications, like remote VMS, geophysical modeling systems, or detailed SCADA diagrams.
RGB Spectrum’s VDA remote desktop is ideal for all of the above applications. Its adaptive compression technology ensures optimized transmission of high-definition motion video, graphics and text over IP networks. With VDA adapters, text and graphics are crisp and clear, unlike VNC’s visuals which are often blurry or indistinct. In addition, VDA adapters provide fluid motion, unlike VNC’s diminished frame update rates, which result in erratic transmission of motion graphics and video.
VDA adapters provide operators with responsive keyboard/mouse control over remote system resources. When you move your mouse, you expect a corresponding real-time action regardless of whether a controlled resource is local or remote. With VNC remote desktop control, however, the cursor may jump from point to point rather than directly following the mouse’s movements. In contrast, VDA’s remote desktop capabilities provide operators with more responsive keyboard/mouse control.
So why is responsive keyboard/mouse control important? For applications that require real-time performance, a responsive, low-latency remote desktop controller can help ensure the safety of off-site personnel and minimize damage during critical situations. Consider the following scenarios:
- You are monitoring an access control system and need to stop an intruder from entering a building
- You are a law enforcement officer accessing footage from a remote VMS to apprehend a criminal
- You are a plant supervisor who must immediately stop an assembly line to repair malfunctioning equipment
For these and other use cases, operators must be able to view full-motion video from monitored sites in real-time so that they can respond effectively to emergencies. With VNC, there is a noticeable lag between action and response that can put both lives and infrastructure at risk. In comparison, VDA remote desktop adapters provide both real-time video processing and low-latency keyboard and mouse response to enhance operator awareness and response.
VDA remote desktop technology provides a compelling alternative to VNC. Whether you consider image clarity, real-time performance, or low-latency response, VDA is designed to deliver high-performance results at any bandwidth.
