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

A: Considering that some cables are easy to 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.

Video Wall Controller

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

A: Traditional Matrix Switchers is modular with input and output cards, while AVCIT video wall controller over IP is a pure network infrastructure solution, easy to configure and connect by CAT. Encoder connects to the input source while Decoder connects to the video walls.

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

A: No. AVCIT IP Video Wall Controller is a decentralized solution without requiring any centralized PC for management. It is connected by Encoder and Decoder, and requires only one GB Lan switches.

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

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


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

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