ATEN VE814AT HDBaseT HDMI Transmitter Unit 4K 100m

Overview

The ATEN VE814AT is the transmitter half of the VE814A HDBaseT extender kit, designed to push 4K HDMI signals up to 100 meters over standard structured cabling. If you're installing displays, digital signage, or presentation systems where the source device sits far from the screen — think conference rooms, auditoriums, or command centers — this unit handles the source-side connection. The VE814AT accepts one HDMI input and transmits over a single Cat cable run, eliminating the need for active repeaters or dedicated AV cabling infrastructure. Note: this listing covers the transmitter unit only; a compatible HDBaseT receiver is required to complete the link.

Compatibility

The VE814AT pairs with the ATEN VE814A receiver unit as part of the VE814A extender system. It is designed for use within the ATEN VE814A series — verify your receiver matches before ordering. Two SKU variants exist: VE814AT-AT includes a functional RJ-45 Ethernet pass-through port (1 x RJ-45 Female) for devices that support Ethernet over HDBaseT; VE814AT-ATA does not include Ethernet functionality. Confirm which variant your deployment requires before purchasing. Cabling compatibility: Cat 5e or Cat 6 supports 4K up to 70m and 1080p up to 100m; Cat 6a or ATEN 2L-2910 Cat 6 cable extends 4K reach to the full 100m. If your run is 70–100m and you need 4K resolution, Cat 6a is non-negotiable.

Installation Notes

Maximum cable from transmitter to source device (HDMI connection side) is 3 meters — plan your rack or equipment placement accordingly. 4K is supported at 4096×2160 and 3840×2160: at 60Hz in 4:2:0 color space, or at 30Hz in full 4:4:4. If your source or display requires 4:4:4 at 60Hz, this extender does not support that combination — verify your AV chain's chroma requirements before deployment. Power is supplied via a locking DC jack; firmware upgrades are handled via an onboard slide switch. Operating humidity range is 0–80% RH non-condensing.
