Designed for modern audio and video installations, this kit includes a dedicated AV transmitter and receiver set to enable reliable wired connectivity up to 100 meters. By utilizing existing IP networks, the system allows users to transmit ultra-high-definition content with maximum resolutions of 3840 x 2160 pixels. It is engineered to meet the demands of commercial environments, control rooms, and large-scale digital signage networks where scalable video distribution and centralized management are required.

Advantages

This extender kit offers exceptional flexibility by leveraging standard network cabling, eliminating the need for dedicated point-to-point lines over extended distances. The inclusion of a mobile video control application for iOS and Android devices allows administrators to manage video routing, rename sources, and configure displays remotely. Furthermore, the architecture supports scalable configurations such as one-to-many and many-to-many setups, enabling growing businesses to expand their video wall capabilities without replacing core hardware. Integrated audio routing and serial control support via RS232 passthrough add further versatility for managing connected hardware.

Suitable for

• Professional AV distribution in corporate offices and educational institutions
• Digital signage networks in retail spaces and hospitality environments
• Multi-display installations and video wall configurations in control rooms
• Point-to-point high-definition video extension over Cat5e cabling

When it may not be suitable

This product may not be suitable for basic residential setups that lack a dedicated local area network switch or do not require extended distance signal distribution. Additionally, environments utilizing unmanaged network switches without proper configuration support may experience bandwidth limitations when streaming high-resolution 4K video.

How to use

To set up the system, connect the AV transmitter to your video source using an HDMI cable and link the receiver to your display device. Connect both units to your network infrastructure using Cat5e cabling, ensuring that the necessary network switches and protocols are properly configured. Power the units using the provided power adapters. For advanced configurations, install the video control application on a compatible mobile device connected to the same network to manage display layouts, source switching, and video wall arrangements.

What to consider before purchase

• Verify that your existing network infrastructure supports the bandwidth requirements and multicast capabilities needed for 4K video streaming
• Determine whether your installation requires point-to-point extension or a larger one-to-many or many-to-many network configuration
• Check if additional receivers will be required for expanding the display network beyond the initial transmitter and receiver pair

Usage recommendations

For optimal performance in multi-transmitter or multi-receiver environments, use a managed network switch with IGMP enabled and ensure jumbo frames support is active to prevent network congestion and maintain stable 4K video delivery.
