For managing multiple computers at once, IP KVM is an invaluable device. It allows you to complete work on the network without having to use the keyboard, monitor, and mouse, but through the network. The only downside is that they will become expensive, unless you can of course be based on Raspberry Pi and
Only higher than the cost of Pi itself.
The video link below shows how to make all the settings, including refreshing the image, and then setting up the necessary hardware. This version shows an option to use HDMI via USB, but another option to use the CSI bus will allow control of options not allowed by the USB HDMI dongle, such as video resolution and color. It also makes it possible to restart the computer and perform operations such as configuring the BIOS or booting from removable media, which is not possible with remote desktop solutions such as VNC.
The creator of PiKVM is
, Pi hat based on this version will be available soon, which will also include the option of ATX control. However, now, you can build all of these yourself without wearing a hat, which is part of what makes Pi-KVM impressive and very low-cost.
Assuming that all computers have network capabilities, why not use one or more instances of remote desktop applications? No additional hardware is required. You only need the keyboard, mouse and monitor once to set up each remote computer, and then run it headlessly. Set the remote desktop application to start at startup so that the remote connection will still exist after restarting.
Until you need to change the BIOS or log in to single user mode after a failed kernel update/parameter change, etc. That is, you have always been unable to get the desktop up and running.
Or, if the machine is unresponsive, the administrator needs to be reset.
As he said in the video, this option allows you to remotely access the BIOS and mount the CD.
> Assuming that all machines have network capabilities
This is a wrong assumption. Sometimes, you may misconfigure the firewall, or delete the default route, or the network card driver update fails, the disk crashes, the startup fails, and it falls into the recovery console... Many things make the computer start, but it cannot be accessed.
This is not for desktop computers, but for servers in data centers or server rooms. You don't want to physically get there to restart the server and change the firewall or routing.
I was thinking: "I wonder if they did it right and have a read-only file system in pikvm" to maximize the life of the SSD. To my surprise, one of the functions is "read Ready-to-use operating system with functions. -only file system".
This is a lovely idea, but I think it is more economical to buy a motherboard with IPMI in the first place than to fix it on it.
I totally agree, but you will never put IPMI directly on the Internet, because the binary blob firmware will never get the update it deserves.
This is the purpose of VPN.
I bought a server motherboard with IPMI. The IPMI is based on JAVA. So atm, I need to solve the trouble of downgrading the web browser and accept many exceptions related to JAVA. Even then, IPMI is not reliable due to all "hackers".
Therefore, a cheap and scalable external solution is really great for me.
This is why we use IP KVM with our employers. Thankfully, since my employer's field (usually) has a lot of money coming in, we can afford shiny Raritan KVM units of more than 10,000 rubles. (They are very shiny and worth it.)
Honestly, I disagree, I have a server board with built-in IPMI, but it is very old, so it is based on Java, this solution will allow someone to use ryzen apu, providing you excellent performance with a lower TDP .
You can also use an external hdmi kvm switch, which means you can control multiple servers through one pikvm.
Not to mention that this allows VNC.
A board with a good IPMI implementation is a stupid, expensive custom server board.
Has anyone tried ZeroW? You must compile the operating system according to the instructions. Curious about the effect of the smallest RPi.
It performed surprisingly well on the Raspberry Pi Zero W and was my preferred configuration. Not only can it be fully powered by the 1A USB host interface using the OTG port, but its performance is surprisingly excellent compared to some of the enterprise solutions I use.
If you need to control a host that is powered off or require reliable power when accessing the BIOS during a host reboot, you need to use an appropriate power/data distributor to provide external power. In the end, I prefer to use Pi Zero W for PiKVM, but there are reasons to use Pi 4, such as encoding performance and connection options that Pi Zero W does not have.
thanks for sharing! That's great information, and one of my zero numbers will be set here soon. Already have a USBHDMI dongle
Don't knock on an interesting project, but as a solution to the problem, you can get an old enterprise-grade Dell/hp network KVM on eBay for less than $100.
They are part of IPKVM, but they have not been overly actively implemented in every part of the entire network.
Not to mention, if you have a Pi 4, an SD card, and a USB capture device, and suddenly find that you need KVM, you only need to flash the latest PiKVM image to the SD card, and then plug it into the Pi. 4. And, if the system has a USB 3.1 Type C (3A) port, you only need two cables to connect it.
Most IP-KVM devices priced under $100 are very clear-they don't support KVM over IP, and they certainly don't have control pins or GPIOs. They can be connected to the computer's control pins with proper isolation. Although IP-KVM has its purpose, the PiKVM project undoubtedly fills a niche market that IP-KVM does not have.
Yes it is. Instant availability, compatibility with any computer, and price are the advantages of this project, and it is undeniable.
The starting price of a commercial IP KVM with one port is about $500. Those with more ports are even more expensive, and you also *need* to purchase an expensive additional cable for each computer you want to connect. Also, you rarely get all the features provided by this feature, and you rarely get flexibility.
Not to mention the old software and the limited compatibility associated with most business units.
Someone also talked about the "network" KVMs that can be purchased on eBay for a hundred dollars... well, these are really just KVMs that use CAT5 cables and (sometimes) can carry longer cable transmissions. Unless otherwise stated, they are not IP KVM.
The few IP KVMs found on the second-hand market are usually more expensive.
For those who want an off-the-shelf KVM, ATEN may currently be the only brand that actually sells IP KVM for less than US$500.
Why does this virtual screen display SETUP with a resolution of 800×600? Is it zoomed? Square pixels?
I think BIOS usually uses VGA text mode with 720×400 pixels. Or is this UEFI disguised?
Obviously UEFI. Even the CSM module version is mentioned in the screenshot.... The resolution of 800×600 is much higher than the resolution of 720×400.
I have been using Michael Lynch’s IP-based KVM over IP for Tiny Pilot Raspberry PI 4 for several months, and it works very well –
This looks cool, I am very happy that more players are entering this field
FYI, PiKVM has a longer running time, and is more refined and more comprehensive than tinypilot. It has been in development for many years, and when you find the features you want small pilots to have, PiKVM may have done it.
I am glad to know that I plan to try it when I have time.
I can say that Michael's customer service is top-notch
Now, it only needs another MCU to monitor the KVM and have a LoRaWAN link to restart it, and so on. If it is not working properly, then if it stops responding, an even smaller and more powerful MCU will also have its own watchdog timer to restart the LoRa MCU.
If it stops responding, another timer is required. Some kind of general-purpose timer chip might...
As mentioned in the video and other articles, mini KVMs (such as iDRAC and ILO) not only use Java, Flash, ActiveX or other esoteric network technologies... they will no longer receive secure firmware updates after their lifespan expires.
Working in a corporate environment is called PCI compliance. Moreover, if you have any interaction with the federal government, you must meet other additional regulatory requirements. All of them recognized CVE vulnerabilities and marked the techniques used in these ancient kvms. Then, you must write the reason for the exception to be approved by the internal auditor and SecOps.
And this seems to be the latest. Because you are using someone’s Arch Linux software, this solution may not be feasible for many companies because the solution has not received commercial support, review, and compensation. But this is a step in the right direction.
You can definitely use it at home and amateurs. You may be able to use it in small and medium-sized businesses, depending on how you supervise it. However, the project is not a solution for a large commercial entity-it does not seem to be its target audience.

Remote access is great, but if the computer stops starting, stops connecting to the network, or requires low-level interaction (such as BIOS settings or startup management), remote access is useless, because remote access is only available after the host is up and running. The usual solution is to drag the keyboard and monitor to the problematic machine for physical access.
For most people, swapping cables in this way is an uncommon task at best. But for those who work closely with hardware management or software development, the need to plug and unplug the keyboard and monitor into and out of the machine can be annoying. The modern solution is IP-based KVM (keyboard, video, mouse), but commercial options are expensive. [Michael Lynch]
, Including Raspberry Pi and USB HDMI capture devices. It does have to remove the "M" from KVM (which means it does not yet support the mouse), but everything else can be used and can be done through a web browser.
What exactly does TinyPilot do? It can provide remote access through a web browser, but from the perspective of the host, the device is an independent hardware, no different from a physical keyboard and display. This means that keyboard and video access can work before the host starts, so there is no problem even if the BIOS settings are changed.
[Michael] demonstrated his design in the video embedded below, but we recommend you
Attract people to explore all the challenges encountered during the development of TinyPilot.
Interested in? Do it yourself, or as an alternative [Michael]
. TinyPilot does not provide an interface with the host power switch, but if you need to add this interface, you can use
How to integrate the relay module with your own DIY.
Is this feature useful if you work remotely on a system that is not designed for the task I think? According to my experience, most remote work is done on a system with light-off management function (
) Function or VM (Is anyone in Citrix Farm?).
We have servers with IPMI, but still need multiple KVMs to handle failure/failure/failure IPMI, client colocation machines, serial connections on switches, etc. Mainly the first one, because IPMI sucks
Things like iLO are a godsend. I hope that desktop users can integrate it into ordinary systems.
They did it. It’s called Intel vPro. People hate it. The rest of the Intel ME (Management Engine) is because if it’s not configured properly, it’s a huge backdoor, and in 95% of my work, it’s very Configure less in the following locations. All of this makes you vulnerable to someone plugging in the USB and configuring it so that you can provide them with persistent system access.
Ok! I also have such an HDMI capture dongle. My idea is to integrate the camera feed with libvncserver in some way, because I have provided keyboard/mouse support in libvncserver.
It seems that the v4l support in libvncserver is part of x11vnc, so it may not be difficult to make the v4l device as a frame buffer.
Haha! It seems that X11VNC already supports exporting the v4l frame buffer:
Therefore, porting keyboard/mouse stuff to x11vnc may be faster than porting v4l stuff to my existing code.
Those HDMI capture dongles are interesting, is there more documentation on them? Which linux driver is it? Is it the main line? Which chip is in these dongles? Any lsusb?
They come in the form of USB Video Class devices and therefore use standard UVC drivers. Look for the Twitter topic referenced in the linked page (Arsenio Dev) for disassembly. I believe the chip is not marked.
More information here:
The Twitter thread is here:
So far, almost all the data available on the dongle:
Or add esp8266 as keyboard and mouse?
If you need serial console access, stm32 blue medicine can also act as a HID keyboard, mouse and USB serial dongle.
It uses Pi4's USB device controller to display as any USB device, in this case a keyboard. I think he just hasn't figured out how to capture the mouse movement in the browser and convert it to a USB report. The second part is very simple, the code has been linked above. The first part is why I chose to use VNC instead of writing my own protocol: the usability of many client implementations!
Can it be programmed to detect the coordinates of the click and then simulate a graphics tablet or touch screen?
MaMe82's P4wnP1 has implemented a USB HID absolute positioning device (not sure of the exact term, but close enough), which will be an exact match of VNC. My code subtracts the previous position from the current position to get relative movement to simulate a more traditional mouse. Obviously, if the mouse exits the VNC window and re-enters from the other direction, there will be a considerable jump.
If the first part is to capture the cursor position, it is very simple.
If it is easy to hide the mouse, it may be difficult to find the motivation to put it together.
I also found that the cheap CH552 can serve as a keyboard and mouse:
They spent 30 cents.
The USB device controller is already built into Pi4 and several other inexpensive SBCs. Of course, you first need a kind of wizard that can handle HDMI streams! It may also be Pi 4, BeagleBoneBlack or Orange / Nano Pi
Does VGA have a dongle at a reasonable price?
In a quick search, it looks like the lowest price captured by vga-usb is $60 on newegg.
I quickly made a Newegg check and found at least one for $11
"VGA to HDMI adapter/converter with audio (old PC with HDMI to new TV/monitor),"
In this way, it is possible to convert the VGA output to HDMI output, which can then be captured by the HDMI dongle.
Is this speed fast enough when changing the display mode?
When I need a KVM adapter, I usually enter the BIOS, select another boot device and similar things. When restarting, most systems tend to change the graphics mode in rapid succession, and the time interval is short, you need to press the correct key sequence to abort the regular startup and enter the BIOS menu or boot menu.
I tried several other homemade solutions and hdmi capture modules. Unfortunately, they either take 3-5 seconds to change the display mode (you can't see anything during this period) or even completely disconnect when the mode changes (Elgato Camlink 4k).
If you don't like it, please crack it.... Have you tried sending screen lock/pause every few seconds? Slow down until the mode change is made.
I have a monitor that looks a bit like this: "Oh, you have changed the screen mode, let me show you a messy corner of it, and I realized that now I want to clear the screen, from inside me The user interface pops up a "screen mode change" box. Now, I will display a few scrambled screens and make some strange clicks when I browse the screen mode, and then I will completely black the screen (counting to 2), making you I think the weird click surprised me, TADA! !! There is the screen mode you want, oh wait, drag it...TA...Oh, push it up and down... Finally, you can go ….. It happens at approximately the required reading speed.
I used to have the exact same ViewSonic monitor. ; D
I have the same idea to use HDMI->USB dongle for KVM type applications.
However, when I got the HDMI->USB dongle, I had an interesting first experience.
I plug it into a Windows 10 PC and try to use VLC to "play" the capture device.
It shows the output of the startup screen, but it is hard to understand blocky and low resolution. I think this device is not suitable for capture rates lower than 1080p.
However, after seeing that the example actually runs normally, I tried the "Camera" application built into Windows 10, and the output looked "great"*.
This is a difference between day and night.
I guess this must be just a problem and/or setting on the VLC application, but I am not sure if anyone knows how to make VLC display the dongle output in a readable resolution.
The first thing that comes to my mind is the codec problem. My impression is that VLC does not use proprietary codecs by default. It may be a free implementation... It may be a newer version or plug-in, or something can solve the problem. .
Under the "Capture Device" option in VLC, you can specify the video size, such as 720p @ 30fps
This is a good intellectual exercise, but not extended. You can buy a user's 16-port IP KVM (the mouse can work in it) for $1,000 or $63/port. The BOM cost of a DIY solution without a mouse is $100.
Well, you said it cannot be expanded...but it is an X user, Y port KVM, you can expand at will.
With a cheaper SBC, the price of each port will drop! For example, any OrangePi/NanoPi board with a USB device controller can do the job well, if all they do is relay MJPG to the browser, and the price of these SBCs is around $20.
You can even get a slightly more powerful SBC, and each SBC can get more HDMI dongles. I am pretty sure that Pi 4 can support 2-4 active HDMI dongles at a time. Then, you said that the cheapest Pi 4 is $35, plus an HDMI dongle of $12 per port, plus a small amount of money, such as atmega32u4 or CH552, etc., to achieve each port USB device controller, and connect to the host SBC through I2C or SPI.
If you want to be fancy, the MAX3420E even has a suitable Linux kernel driver, so it may be a fully supported UDC. However, not sure if the driver (or Linux) supports having multiple concurrent UDCs. MAX3420E is very expensive, unfortunately, each chip is about $10!
Please note that for each HDMI dongle and UDC you have, these are essentially "seats" you want to add, or "users" in IP KVM terminology. In other words, these can be active at the same time, so you can allow 2 users to access different systems without stepping on each other. Many commercial IP KVMs use a single capture device and a single UDC, and then select which system to connect to through a large HDMI switch to achieve this function. That is, a "single user" device.
All this tells me that many commercial IP KVM players have taken their customers to ride for too long!
You don’t need more than one SBC, just a 16-port USB 2.0 hub for $25
In any case, you will never use more than one dongle at a time
If you are using this method: N-port HDMI switch + N-port USB hub + SBC + single dongle. complete.
16-port HDMI switch is priced at $300
Another identical project is here:
. The person I saw last time paired the pi with another device for keyboard/mouse output. Take a quick look today as if they added support for rapi4 with host usb and can simulate cdrom.
Yes, after using it for a while... It seems to be quite mature, rock solid, and has a pretty beautiful web interface. The rpi4 and HDMI csi-2 boards are only necessary hardware, which can be up and running with keyboard and mouse support within one or two hours. It also supports connecting the gpio pin as a physical power switch on the remote hit machine, or reading the power/HDD indicator status, and the emulation CD used to transfer files is very good.
By the way, for those who say that it cannot be extended, supporting other machines is simple, just connect the HDMI and USB switches to the gpio pins, and then set them to activate the control between them.
By the way, for those who say that it cannot be expanded, supporting other machines is simple, just connect HDMI and USB switches to the gpio pins, and then select the corresponding input on each pin to be able to be between the machines Transfer control.
I found that the Belkin 4-port HDMI switch has some remote control, so you can place an IR LED on the GPIO pin and control it in this way.
The Belkin HDMI switch I included looks like a fairly ordinary "cage LED appearance sensor" infrared receiver, with a cable plugged into them through the headphone jack.
Therefore, if you know the voltage that those IR sensor modules are usually subjected to, you can do the following:
RPi-> GPIO-> (some diodes/resistors)->headphone plug-> HDMI-switch
I want to do this, but I am not proficient in the voltages involved so much that it sounds simple in a focused meeting.
I would also like to know if you can pass the USB KB/mouse signal from each PC to another PC via the extra HDMI port pins in the HDMI switch, but I don’t know except for "the smallest number of switch pins can even be called Other information other than the HDMI switch, those switches actually passed.
In fact, it may be possible to implement HID through I2C (because the HDMI cable includes an I2C bus). Windows provides support for this (
), but I doubt that this will be a general solution, or it will work at the BIOS level.
Maybe this will help. Because I am working remotely and have a 34-inch curved 4k screen (emphasizing screen space), I want my work IT to install a borderless Microsoft mouse so that I can use my personal computer or the same mouse and The keyboard works. Due to the nature of the server/client relationship, they rejected the request. The mouse without borders may be your solution. My solution is to use chrome remote desktop on my work laptop and connect to my work laptop in dual monitor mode. In this way, I can switch to a personal PC that is also connected to the monitor. The mouse and keyboard are still connected to the work PC.
On eBay, that bargain is $8.07, but if you pay another $5, you can get a USB60 instead of a 30fps version.
And how to connect some GPIO pins to the PC's hardware reset switch to force a restart on the hung system?
I think the USB3 version is a scam:
It seems that all cheap USB-to-HDMI capture devices are just different packages around the same MacroSilicon MS2109 chip, so they will all have the same performance.
Those are scams
There is a real 60fps USB 3.0 capture card on eBay, $65 Wiistar USB 3.0. Older and larger multi-chip design. You can find them on AliExpress for $25, so they are still worth it.
At the time of writing this article, I remember that I have a dongle and an orange pizer0, it takes 2 hours to download images,
Update the operating system, and the instructions from
For debian, it works fine (with some problems).
I cut the USB and recognized it, but since I also have the "video capture with loop" function, it doesn't work
(Yes, it’s the same insede chip), because it needs more power, and has auxiliary USB power, and has
When the TV cannot receive any input source, it is a good TV color screen.
That's just a simple test, but if you can power the sbc through GPIO, then you can use a super cheap
NanoPi NEO-LTS starts at $10, if these guys use external power to develop hdmi capture hats
They will have a good product.
Otherwise, you will need to use an external power supply. For this, you can use:
The rest is the software configuration. Now that it’s ready, it’s just time
The last point is that the CPU is really hot, so the heat sink is crucial for this.
The choice in my mind (not that I have tried their products)
The pikvm project has indeed taken off, and even supports user-defined GPIO pins on the web interface to control various devices or display signal status. It is ideal for controlling Aliexpress's cheap physical USB/HDMI kvm switch.
So far, I have seen the most mature and fully open source IP KVM project. Even CDROM/Flash emulation. Still trying to make the Windows server image available for Flash emulation.

It can be seen everywhere that audiovisual technologies have migrated to IP networks for a variety of reasons, including easy scalability and remote access convenience. However, as engineers work hard to clear obstacles to delays, quality and safety, the process is relatively slow.
For the KVM solution, these three shortcomings cannot be started. Usually found in mission-critical command and control environments, KVM-over-IP solutions need to be agile enough to achieve smooth mouse movement, have a high enough resolution to view important details, and be robust enough to Meet safety and reliability standards.
The following products check all these boxes and make the life of the technical manager easier and more efficient in the process.
The new ADDERLink INFINITY 4000 supports Gigabit Ethernet, improved video resolution and advanced diagnostic functions, allowing customers to better control when and how they choose to integrate 5K into their IP KVM network. As the adoption of 5K continues to grow, so does the need to maximize available bandwidth without sacrificing pixel-perfect image quality. To meet this demand, Adder introduced multi-gigabit Ethernet support, which means that customers can balance their video quality and bandwidth usage requirements by providing 5K on various network functions from 1Gbps to 10Gbps. This version also provides high-quality immersive sound through DisplayPort digital audio, and a new on-board diagnostic tool that allows customers to troubleshoot KVM networks.
ATEN's KE9950 4K DisplayPort IP expander single-display KVM provides a video resolution of up to 3840x2160 at 30Hz (4:4:4), and lossless video compression quality without delay. The solution consists of a 0U rack-mounted high-performance IP-based transmitter (KE9950T), which is connected to a computer and receiver (KE9950R), and the console can be accessed from a separate location. KE9950 allows 24/7 access to the computer system via a remote USB console via the Intranet, enabling users to locate the computer in a safe and temperature-controlled environment isolated from the user workstation. To increase security, the extender supports AES encryption for secure data transmission, while RADIUS, LDAP, AD or remote user authentication provides an additional layer of connection security. The solution is very suitable for a variety of work environments, including traffic management centers, retail monitoring centers, facility status rooms, command control centers, utility process control centers, broadcast distribution monitoring systems, network operations centers (NOC), and other industries that require a matrix Need to expand.
The Emerald KVM-over-IP system is a future-oriented KVM matrix switching solution that supports HD and 4K video at 60Hz and 10-bit color depth, as well as USB 2.0 and audio. The KVM receiver acts as a zero client and can access physical servers and virtual machines in a single KVM network. Emerald can scale to as many users and servers as needed, and provides fail-safe network redundancy, making it ideal for MCR, post-production, and all other critical production environments. Use Boxilla KVM Manager to maximize the performance of any KVM matrix with more than 25 endpoints. Emerald is developed and manufactured by Black Box, focusing on reliability and performance.
Crestron DM-NVX-D80-IOAV is a compact AV decoder over IP that can act as a receiver. DM NVX D80 is compatible with Intel's Open Pluggable Specification (OPS) and can be seamlessly integrated with OPS-enabled displays. DM NVX technology supports the expansion of USB signals, which can be switched and routed together with AV signals or separately through the control system. The OPS port of DM-NVX-D80-IOAV has the function of a USB 2.0 host port, so that DM-NVX-D80-IOAV can be used as a remote extender. The OPS port receives USB signals from KVM (keyboard, video, and mouse) devices or other types of USB peripheral devices. The USB signal is transmitted over the network to the USB 2.0 device port of the DM NVX device, which serves as a local extender and sends the USB signal to a USB host device (for example, a computer).
With near-zero latency and visually lossless video transmission, Datapath Arqa brings many benefits to end users. The Arqa KVM system utilizes optimized IP video transmission technology, which can greatly reduce latency and provide immediate control. Strict testing has shown that there is no difference between operating a PC via Arqa or directly connecting the connection to the local desktop. With the increase of security issues and the AV/IT team's commitment to more streamlined management processes, the convenience and benefits of KVM control have become more and more necessary for the control room architecture. With Arqa, the maintenance team can put all PCs in one place, saving time, saving desktop space and keeping hardware safe. Another benefit for the end user is Datapath's One Control technology, which allows the operator to switch between up to 16 independent sources as if they were a desktop computer without pressing any buttons. Since the system essentially acts as an IP matrix switch, users can select up to 2,000 endpoints in the system.
NAV is a professional IP video and audio solution for distributing and exchanging low-latency, high-quality video, audio and USB 2.0 signals at a low bit rate via Ethernet. Using Extron's patented PURE3 codec, it can provide lossless video over IP with a resolution of up to 4K60, 4:4:4 chroma sampling and ultra-low latency. The visually lossless video and ultra-low latency make it suitable for high-performance computing KVM applications or any other deployments that require real-time interaction with the original video quality. It also supports AES67 audio over IP, facilitating flexible integration with DMP 128 Plus DSP or other audio components that support IP. NAVigator System Manager has an easy-to-use interface that can centrally manage and control any NAV system, thus simplifying the setup and configuration process. In addition, it also has extensive functions for monitoring, diagnosis, and troubleshooting. The highly scalable NAV platform is designed to support demanding professional KVM and AV applications, and can safely deploy AV and USB signals to thousands of endpoints.
ControlCenter-IP combines the advantages of a classic matrix with the flexibility of an IP system. Any connected operator station can be granted access to any remote computer. When the network infrastructure uses network switches and routers to take over the KVM transmission over IP, ControlCenter-IP is responsible for the logic. The transmission is compressed through the category cable or optical fiber through the IP-based standard network, and the data transmission rate of each line is 1Gbps. This allows existing IT installations to be expanded more easily, flexibly and cost-effectively. The ControlCenter-IP system provides high-quality images and uses internal compression technology HDIP. This compression mode can transmit video signals losslessly at 60Hz with a resolution of up to 4K. Combined with the IP extender system for DP1.2a and DP1.1a and single-link and dual-link DVI, it supports a wide range of video signals with an IP resolution of up to 4K. Using ControlCenter-IP, users can integrate general USB devices and high-speed USB 2.0 into the KVM installation on the IP. It also provides the MatrixGuard function to provide additional security in the event of a failure. With MatrixGuard, a secure redundant cluster can be implemented in the KVM environment over IP.
Last year, IHSE introduced a virtual KVM solution that allows virtual servers to coexist as part of the existing Draco tera KVM switch system, thereby creating a simplified multi-tasking virtual environment in which multiple locations can be accessed directly from the physical KVM console Operating systems and applications. This year, IHSE expanded these network functions by introducing the Secure IP Remote Access (SIRA) series of IP KVM solutions. SIRA includes a large number of gateways and remote access products to create hybrid KVM solutions. The new SIRA model reduces the time and cost associated with managing multi-site computer sources by combining network workstations and local computers under a secure display management system. SIRA connects the KVM matrix to a private or public TCP/IP network, thereby bringing greater flexibility to the Draco tera matrix without sacrificing the philosophy of separating the core matrix and signal management from TCP/IP security. This allows better high-performance remote access to the target device of the connection matrix through an HTML browser or soft client. Encrypted signal transmission via IP ensures intellectual property protection, while still providing the most flexible access from remote locations via private or public networks.
