KVM matrix systems are crucial in integrating audio and video setups, offering remote KVM, multi-point distribution, and switching capabilities.
In recent years, the introduction of IP technology has led to the widespread adoption of KVM over IP switches in various projects and installations.
In this article, we will explore the multiple benefits of the KVM over IP Matrix System and compare it with traditional non-IP KVM matrix switches to help you find your best choice.

Understanding KVM over IP Technology
The KVM over IP technology converts audio, video, keyboard, and mouse signals into IP signals and transmits these signals of KVM over ethernet cables, allowing for control over the IP.
Once the signals are transformed into IP signals, they acquire the characteristics of a network system, enabling seamless control and switching between various endpoints.
In addition to audio/video, keyboard, and mouse, some devices even utilize network cables to transmit RS232 signals or achieve one-way power delivery.
- Network Cabling
KVM over IP matrix switch systems use network cabling to connect computers and monitors, with a switch in between. The cabling can extend up to 100 meters, effectively increasing the distance between devices.
- Distributed Matrix
With the extended distance between computers and monitors, devices such as computers and monitors can be distributed across different areas while still maintaining the matrix functionality.

KVM over IP Advantages
| KVM Matrix | KVM over IP | |
|---|---|---|
| Latency | Extremely low* | Tens to hundreds of milliseconds* |
| Length | 5 - 10 meters* | 100 meters over network cables or longer over fiber optics |
| Scalability | Low | High (Limitless) |
| Remote KVM Control | No | Yes |
| Control Ways of the Matrix | Panel buttons, IR remote control, RS232, Web GUI, software, app, etc | |
| Cost | Low | High |
*When used with video extenders, some latency may still be present.
*Video transmission over IP typically utilizes H.264 or H.265, and latency depends on the performance of the selected equipment.
*For higher demands, video extenders can be used in conjunction with the KVM over IP Matrix.
KVM over IP Matrix Structure
Non-IP vs. KVM over IP Matrix Comparison
Security
- Non-IP KVM Matrix:
General matrices use network cables solely for extension and audio/video interface connection. Without direct access to the devices, the data is not at risk of being attacked or stolen.
- KVM over IP Matrix:
KVM over IP Matrix utilizes IP networks for signal transmission, which opens up the possibility of external network intrusion, introducing some security risks. However, robust KVM over IP systems usually provide encryption and security features like SSH and SSL to ensure secure access and control.
Scalability
- Non-IP KVM Matrix:
The scalability of a general video matrix is limited by fixed audio/video interfaces and ports. Once the demands upgrade, such as an interface update or additional devices being added, it requires additional video matrix switchers and devices, making it relatively expensive.
- KVM over IP Matrix:
KVM over IP Matrix converts all information into IP signals, allowing for seamless compatibility between different devices and audio/video interfaces. It generally offers better scalability, unrestricted by connection ports, with lower expansion costs.
Latency
- Non-IP KVM Matrix:
Since general matrices are real-time audio/video transmission, the latency is typically low, making them suitable for applications requiring high and real-time performance.
- KVM over IP Matrix:
KVM over IP Matrix tends to have higher transmission latency because data needs to be compressed and decompressed, leading to slight delays. Latency with the common H.264 or H.265 can range from milliseconds to hundreds of milliseconds, but high-quality KVM over IP systems can optimize this latency.
KVM Control
- Non-IP KVM Matrix:
KVM functions in matrices require on-site devices for operation, as they are not externally accessible.
- KVM over IP Matrix:
KVM over IP Matrix enables remote access KVM via external networks, enabling remote use through web browsers or dedicated management software for remote access and control.
Cost
- Non-IP KVM Matrix:
The setup of traditional matrices usually costs less with relatively cheaper equipment prices, making them suitable for budget-constrained scenarios.
- KVM over IP Matrix:
The initial setup of KVM over IP Matrix generally costs higher due to advanced features and remote access capabilities. They are more suitable for scenarios with ample budgets and requirements for remote management and scalability.
How to Choose a Suitable KVM/AV Matrix System
After understanding the respective advantages of general non-IP KVM Matrix and KVM over IP Matrix, SC&T can conclude and provide recommendations for your matrix selection:
- If you require simple local connections (within 10 ports) with high real-time performance and a limited budget, you can opt for a non-IP KVM/video matrix switcher. Suitable scenarios include company meeting rooms and lecture halls in schools.
- If you have a more generous budget and need remote access, cross-site control, and future scalability, we recommend using a KVM over IP Matrix. Suitable scenarios include remote offices, data centers, and multi-location, multinational corporations.
