New Gen of Encoder/Decorder

ZowieBox is a new generation of hardware encoder/decoder in a small aluminum box, and an ultra-compact video streaming encoder and decoder with HD video. In addition, it features NDI®| HX3, PoE, a standard tripod mount and a big distinct tally light. What’s more, it is cost-effective and user-friendly.
ZowieBox supports popular USB Type-C charger, WIFI, hotspot, DC output and a range of innovative modern features. It is a standalone streaming encoder without a PC, which is a flexible and affordable solution to stream high-quality video over a network for system integrators, streaming professionals, and OEM partners.


ZowieBox can easily mount onto any SLR camera using a standard 1/4-inch tripod mount. It effectively converts existing video signals from professional cameras and display screens into real-time, high-quality IP video streams with low latency, all compatible with NDI technology.

Powerful encoding and decoding

ZowieBox can encode formats such as H.264 HP/MP/BP, H.265/HEVC MP, NDI, NDI|HX2 and NDI|HX3 as well as SRT, RTMP, RTMPS or RTSP protocols whose bitrate could be up to 50 Mbit/sec. Simultaneously it can directly push streams to multi-platforms such as Facebook, Twitch and YouTube, without a PC. Alternatively, these IP streams could decoder into high-quality SDI outputs.

AV over IP to NDI

For AVoIP video streams, including protocols like RTMP, RTSP, and SRT from DJI drones, GoPro, and action cameras. ZowieBox excels at decoding these streams into NDI video streams when operating in decode mode. This capability positions ZowieBox as a versatile solution for efficiently handling and converting diverse video stream formats over networks. By leveraging its decoding functionality, users can seamlessly transform video streams from various sources into NDI format, ensuring enhanced compatibility and flexibility within NDI-supported systems.

RTMP Media Server

ZowieBox can be used as an RTMP server, allowing users to pull and push RTMP streams. An RTMP Pull stream serves as a playable link for your live stream, which can be configured as a source for another broadcast. This feature is invaluable for consolidating multiple live streams onto a single screen, making it ideal for esports tournaments and conventions. With RTMP Pull links, incorporating live in-game replays, interview translations, and multilingual commentary onto a single screen becomes effortless.


ZowieBox offers SDI connections for USB-C UVC webcams, supports widely used VESA standard resolutions, and resolves output issues commonly faced with USB cameras. It operates without the need for drivers, providing low-latency output that seamlessly integrates your UVC signal with video switchers such as ATEM devices. ZowieBox enhances the capabilities of your webcam setup significantly.

Flexible recording and display

ZowieBox supports streaming and recording simultaneously, with a video frame rate of up to 60fps and a 24-frame movie frame rate. The input can be recorded as files to TF card or USB storage or NAS. The front mini screen can display current settings and working status in real time. If you have unlimited storage space, you can also choose the next-generation HEVC format for archiving and editing.

Simple operation and easy setup

Browser-based GUI, you can control it via computer, phone, iPad, WiFi or hotspot. As long as the user’s mobile phone, computer and ZowieBox are in the same network, they can log in to the control interface without an IP address. In addition, users can find ZowieBox in the same network segment on the configuration interface and control it with one click.

PTZ control

ZowieBox can control the camera via USB to serial RS232/485/422. Converting your camera to a network camera by operating it online.

Multi charger with DC out

ZowieBox can be powered by PoE up to 100 meters away. Alternatively, it can also be powered by a USB-C charger, USB-C power bank, or regular DC power adapter in any voltage between 5 to 20V with DC to USB-C adapter. ZowieBox also features DC out that can deliver 12V DC power up to 12W to power external equipment like PTZ camera, monitor and so on. Moreover, its USB port can also deliver power up to 5W.

Unlimited transmission

Through ZowieBox, any video signal from computers, cameras, etc. can be remotely transmitted to the remote end, and the transmission delay in the Local Area Network is only 100ms; the Network can support long-distance, point-to-point transmission through protocols such as SRT or RTMP.

Build-in tally

ZowieBox includes a built-in large Tally display for your on-air talent to easily see which camera is live, synchronize with OBS, Vmix and NDI, then respond to PGM and PVW.
