Installation Guide: Hardware Setup and Connections — AV Over IP
Overview This guide covers the physical installation of KanexPro AV over IP encoders and decoders — from unboxing to first power-on. Complete this…
General
What is the difference between JPEG2000, H.265, and SDVoE?
JPEG2000 delivers visually lossless 4K60 over 1G with ~1 frame latency — best for video walls and enterprise. H.265 delivers 4K60/HD over 1G with low latency and up to 50% less bandwidth than H.264 — best for large deployments and digital signage. SDVoE delivers uncompressed 4K60 over 10G with zero latency — best for broadcast and control rooms.
Can I mix JPEG2000 and H.265 encoders/decoders on the same network?
No. Encoders and decoders must use the same codec family. JPEG2000 encoders only work with JPEG2000 decoders. The IP controller is also codec-specific — use the correct controller for each family.
How many encoders and decoders can I have on one system?
JPEG2000 and H.265 support up to 9×9 matrix configurations (9 encoders to 9 decoders) when using the IP controller. SDVoE scales with available 10G ports on the switch.
Do I need an IP controller?
No — the IP controller is optional. Without it, encoders and decoders auto-discover each other and can be routed via the web GUI on each device. The controller adds centralized matrix routing, video wall support, REST API, RS-232, and third-party control integration.
Network
Will an unmanaged switch work?
No. AV over IP requires a managed switch with IGMP snooping enabled. Unmanaged switches cause multicast flooding, which saturates the network and prevents video delivery.
Why is there no signal after connecting everything?
The most common cause is IGMP snooping not being enabled on the switch. See Troubleshooting: No Signal Between Encoder and Decoder for the full checklist.
Do I need jumbo frames enabled?
For JPEG2000 and SDVoE: yes — set MTU to 9000 on all AV switch ports. For H.265: no — standard 1500-byte MTU is sufficient.
Can AV over IP share the same network as corporate data traffic?
Yes, but a dedicated VLAN is strongly recommended to isolate AV multicast traffic from corporate traffic and prevent bandwidth contention.
Video Wall
Which codecs support video wall mode?
JPEG2000 only. H.265 and SDVoE do not support video wall mode.
What is the maximum video wall size?
9×9 (81 displays) using the AVO-IPCTL-JP2K controller with JPEG2000 encoders and decoders.
What is bezel compensation?
Bezel compensation adjusts the image crop on each display to account for the physical bezel width, making a continuous image appear seamless across all panels. Measured in millimeters and configured in the controller GUI.
Audio
Which models support Dante audio?
AVO-IPJP2K (optional Dante AV-A) and AVO-IPJP2KD (dedicated Dante LAN port). Dante must be on the same network or a dedicated VLAN.
Which models support ARC/eARC?
AVO-IPJP2K and AVO-IPJP2KD support ARC/eARC. The Slim model (AVO-IPJP2KS) does not.
Installation
What cable type is required?
CAT5e minimum. CAT6 or CAT6a recommended for runs over 50m or for SDVoE 10G deployments. Maximum run length is 100m (328ft) for copper. Fiber SFP is available on select JPEG2000 models for longer runs.
Can encoders and decoders be on different subnets?
No. All encoders, decoders, and the IP controller must be on the same IP subnet for auto-discovery and streaming to function.
