Experience unmatched versatility with the NHD-120-IW-TX, your ultimate AV over IP solution. This 2-gang in-wall encoder, part of our 100 series, boasts an HDMI input and a dedicated Ethernet port, designed to seamlessly integrate with today’s modern laptops and tablets. Whether you’re enhancing your educational setup or optimizing your corporate environment, this encoder is your key to success.
Install it discreetly in a wall, table, desk, podium, or any location where remote input is essential. The NHD-120-IW-TX also offers the flexibility to connect the CAM-210-PTZ camera via HDMI while providing a robust Ethernet connection to ensure your AV streams are pristine and uninterrupted.

TAILORED FOR MULTIPLE MARKETS
The NetworkHD™ 100 Series utilizes low bandwidth, infinitely scalable technology with the addition of powerful video wall support up to 16×16 for the best all-round solution for commercial AV installations. A 100 Series encoder can either be paired with a 100 Series decoder for matrix switching to individual screens or for video wall decoding, with both decoders including HDMI and analog audio breakout outputs, or an NHD-150-RX decoder for multiview monitoring.
H.264/H.265 Encoding
Choose your flavor, the NHD-120-IW-TX can encode AV signal using either H.264 or H.265. Using H.265 provides incredibly efficient video streams. For comparison, an H.265 5Mbps stream is equal to a 30Mbps H.264 stream.
4K Resolution
The NHD-120-TX is now supporting 4K content that ensures compatibility with the HDMI v1.4 HDCP 2.2 video source, while a built-in scaler ensures hassle-free mixing of the latest 4K displays and 1080p screens within an installation.
Compact Design
The simplistic white decora plate and small 2-gang size allows the encoder to be installed and blend in to a number of different environments. The front of the encoder isn’t crowded with unnecessary connections and the support for PoE means you don’t need to run extra cables through the wall.
Ecosystem
The NHD-120-IW-TX is just one of many models within the NetworkHD 100 series. Mix and match different models to tailor your system to your requirements. All of which are controlled and maintained by the NHD-CTL-PRO controller.
