Key Features
- Compact but Powerful: ZowieBox, smaller than phones, with a tally light and LCD screen showing streaming status, can stream console gameplays at 4K capture with zero-lag passthrough. The IP stream can be decoded into a 4K HDMI signal.
- Standalone Game streaming: Just plug and play, ZowieBox can stream live gaming PC-free, not affecting the game experience at all!
- NDI|HX3 Converter: It can encode a HDMI signal to NDI|HX3/HX2/HX. The certified NDI technology enables ZowieBox to stream gameplay from home to global e-sports championship via OBS/vMix in real time at very low delay but high definition. ZowieBox cannot be used as an encoder and decoder at the same time. It can only switch between the two working modes, not use both modes at the same time. Note: It does not support encoding/decoding full NDI signals
- UVC to HDMI: Up to 4K@30fps & 1080p@60fps resolution and decoding solution, ZowieBox allows you to unfold more possibilities of the webcam devices. USB capture card function is not currently supported.
- All-around Configuration: It can be adjusted through web UI by PC/phone/pad to control PTZ cameras connected, Tally light, video/audio, OSD, work mode, stream, network and system. Users can see the preview video and overall dashboard on the web UI.
- HDMI Extender: Using two ZowieBoxes, point-to-point transmission can be achieved. One acts as an HDMI encoder/transmitter and the other acts as an HDMI decoder/receiver. The video signal is transmitted through a network such as a LAN.
