10.How can we display source from internet, such as web, RTP, HTTPS etc.?

We can use a PC to access internet streaming, and connect KVM encoder with PC, then we can display this PC content on video wall.

11.What can be recorded by User Logs System?

Which user account login, the time of login and logout, which PC operator access, which KVM Decoder operator use.

13.When i do I use the secure data communication?

When user need to transmit web camera data, USB drive data between PC and console. Because previous design of node, the USB port can transmit the HID signal of keyboard & mouse only, and now we have option to transmit USB drive data via KVM node's USB port, but if user need to make video conference via Teams, Skype, Zoom etc when working on the PC, KVM Node's USB port cannot transmit web camera's data yet.

14.Can we get multi-view control by touch feature, by connecting 4K KVM Decoder?

The 4K KVM Node for touch screen cannot work in multi-view mode to control multiple PC by touch at same time, And if they need to show multiple screen by 4K KVM node on touch screen, there are two options: 1. Connect a physical keyboard with node, then double press "ALT" for multi-view 2. Log out the KVM account, then use DS Works to control and switch video; but not touch feature

15.How to control the system, or how to control the encoder and decoder?

Some more questions; 1) Audio control, mix upto 16 Audio channels. - 16 Audio channels are for whole system or just one output audio node? - Can be adjusted sound level of each channel? And How to adjust and mix its? - if we use video talk feature in the same time, number of audio channel will be reduce to 14 or still 16 channels? Answer: 1) it's for one output node, every node can output mixing audio up to 16 2) Yes, sound volume can be adjusted, we have the configuring software to design the volume bar on UI, and setting audio 3) video talk feature is mainly for KVM Console, which don't work together with audio mix at same time Pls confirm about these; 1) I/O and I/R port at DSII and DSIII will be able to use must connect E-CP4C in network first. 2) CRV-P8NET also need E-CP4C or can operate separately? Answer: 1) YES 2) If you don't need to control 3rd party device's Power ON/OFF, then you don't need the P8NET, they are different device, P8NET will be controlled by E-CP4C with UDP code That mean when we use P8NET must connect E-CP4C in network also? Answer: P8ENT also can be controlled manually, but if you want to demonstrate the feature of controlling Power ON/OFF by one touch on iPad or Windows PC, then requring E-CP4C.

16.How many bandwidth requirement for each encoder/decoder node ? what’s the bitrate?

It's 4-20 Mbps per streaming, for example, one encoder distributing video to four decoder, then this encoder's uplink streaming bandwidth is 16-80 Mbps. If a decoder displaying four source at same time, the it's downstreaming rate is 16-80 Mbps.

17.What’s gigabit switch required?

We will recommend the Gigabit Switch model according project size. Three most important specification: 1. Switching Capacity; 2. Forwarding Rate ; 3. PoE rate power (20 Watt for each node) It's UNI CASTING: 4-20 Mbps/streaming, 16-80 Mbps for four streaming from encoder

18.Can we adjust encoder’s bitrate manually or automatically?

We can adjust the max. Bit rate limitation for encoder, but the actual bitrates is variable in real time, depends on the content of input source. For example, if the source is playing video, then its bitrate is bigger, if it's just static image, then the bitrate will be small.

19.Why E-CP4C can be PING by PC, but not searched by SisDev software?

If you connect the E-CP4C with USB network card or WIFI instead of PC’s RJ45 port, it’s required to check the network priority between USB network card and RJ45 port. Because SisDev software will search the E-CP4C by high priority network, PC’s default network priority is RJ45 port so that E-CP4C cannot be searched, but OK for PING.

20.How does USB Matrix System works?

From the schematic, we could learn that the USB data could be transmitted two way over USB matrix system by PC >< CPU-USB Node >< USB Matrix >< CON-USB Node >< USB headset/camera/disk etc. For example, the Worksapce # 1 Operator get access the PC 1 by OSD, then the channel between CPU-USB Node #1 and CON-USB Node # 1 will be linked to transmit data, the operator could just plug the headset into CON-USB Node #1 to talk, whose data will be transmitted to CPU-USB Node # 1 for PC#1

FAQs - Guangdong AVCiT Technology Holding Co., Ltd.

Q: What is the difference between AVCIT's Video Wall controller over IP and other traditional matrix switchers?

Traditional Matrix Switchers is modular with input and output cards, while AVCIT video wall controller over IP is pure Network infrastructure solutions, easy to configure and connect by CAT. Encoder Connect to the Input source while Decoder connect to the Video walls.

Q: Does the AVCIT IP video wall controller require a centralized PC server?

No. AVCIT ip video wall controller is a Decentralized solution without requiring any Centralized PC for management. It is connected by Encoder and Decoder, required only one GB Lan switches.

Q: How much bandwidth is needed to transmit the signal by the AVCiT encoder and decoder? How about the picture quality?

It only requires 4-20Mbps, AVCIT encoder, and decoder is H.265/264 coding tech and owns patented ASE encoding tech, and has 2K and 4K solutions.

Q: How many signals can one coder control on a LED or LCD video wall?

Each AVCIT coder can open up to 16 windows on your video wall, and no quantity limitation for sources.

Q: What should I do if the physical cables and ports become loose over time?

Considering that some cables are easy wear and off over time, AVCiT designed a metal clip for each coder for fastening cables with ports, which is also our patent on the market.

Q: What’s difference between DSIII and DSII?

In general, the encoder/decoder node are classified as follows: 1.

Q: How to work with CCTV Cameras ?

There are different options to work with CCTV Cameras, Option 1: Connect IP Cameras with KVM Node's system network switch by UTP directly (as in the schematic you sent). IP Camera should support H.264, H.265 protocol with RTSP streaming; It's OK for projects with small quantity cameras; Option 2: Capture the camera's video content via NVR's physical HDMI/DVI port, by connecting our Encoder Node with it. If so, just consider NVR as a regular video source device; Option 3: Capture the camera list and stream via their VMS platform. It's required customized development to work with platform by their SDK, which takes time to develop and additional cost;
