The tiny rig described in the original 2016 report is VideoStitch’s Orah 4i: four fisheye cameras, four ambisonic microphones and a separate computer that stitches the views into a live 360-degree feed. It is a capture system, not a complete VR broadcast by itself. A usable live event also needs encoding, a streaming server, delivery infrastructure and a 360-capable player.
What the Orah 4i camera rig was
Futurism described the Orah 4i on April 8, 2016 as a compact 360-degree live-stream camera system designed to be “small, inconspicuous, and able to blend in.” The camera body uses four f/2.0 fisheye lenses arranged to capture a full spherical view and four ambisonic microphones for spatial audio.

Unlike an all-in-one consumer camera, the Orah 4i sends its feeds to a separate stitching box. That box contains an Intel CPU, Nvidia GPU and a 120GB SSD, along with two Ambarella video chips in the camera system. One Ethernet cable carries both data and power between the camera rig and the stitching box. This division keeps the camera small but adds a dedicated computer, cable and mounting position to the production setup.

What a live VR broadcast needs beyond the camera
A headset viewer does not connect directly to lenses. The complete path has five functional stages:
- Capture: a 360-degree camera records overlapping views and, where supported, spatial audio.
- Stitching and encoding: software or hardware joins the camera feeds into an equirectangular 360 video and compresses it for streaming.
- Media-server ingest: the encoded feed enters a server, commonly through RTMP in the workflow documented by Wowza.
- Delivery: the server packages or distributes the stream through a content-delivery network.
- Playback: a browser or headset application uses a 360-aware player so the viewer can look around the spherical image.
Removing any one of these stages leaves a production gap. A camera that records 360 video is not automatically an RTMP encoder, CDN, or headset player.

A documented 4K-to-HLS workflow
Wowza’s 2020 tutorials use an Insta360 Pro 2 as the capture device. The camera is configured for a custom RTMP server and a 3840×2160 (4K) output. The resulting stream is handled by Wowza Video or Wowza Streaming Engine, delivered through a CDN and played in a 360-capable web player such as THEOplayer.
Configuration sequence
- Prepare the camera: connect the Insta360 Pro 2 to the network and select its custom RTMP-server mode.
- Set the video format: choose 3840×2160 output, as in Wowza’s example. Confirm that the camera, encoder and network can sustain the selected bitrate.
- Provide the ingest endpoint: enter the RTMP server address and stream credentials supplied by the media-server service.
- Configure the media server: accept the RTMP input and create the 360-compatible output workflow.
- Package for viewers: use HLS playback and distribute it through the selected CDN.
- Use a 360-aware player: load the HLS stream in a player that exposes spherical navigation on a phone, browser or VR headset.
- Test the entire chain: verify camera orientation, stitching seams, spatial audio, ingest stability, playback controls and end-to-end delay before the event.
How much delay should you expect?
Wowza’s Streaming Engine tutorial says its low-latency HLS option reduced the usual HLS delay of 30–45 seconds to approximately 10–15 seconds in the demonstrated setup. Those figures come from that 2020 configuration; they are not a universal performance guarantee. Camera processing, stitcher load, encoder settings, upload capacity, server configuration, CDN behavior and the player’s buffer can all change latency.
Rank #3
- 360° video conferencing camera with built in ominidirectional microphone
- Six display modes deliver exceptional viewing angles with flexibility and versatility
- Full HD 1080p video playback @ 30 Hz
- USB UVC/UAC plug-and-play with touch bar to specify participants’ location. *Note: App permissions may need to be authorized in order to use the camera. An upgrade of the firmware to the latest version may be required in order to optimize the webcam's functionality and resolution.

For a live VR event, measure delay from a visible action in front of the camera to the same action in the headset. If interaction is important, reduce segment and buffer settings only after confirming that the network remains stable; an aggressive latency target can produce stalls or dropped playback.

Choosing equipment for a live VR event
Choose a compact multi-camera rig when
- You need a discreet camera footprint and can accommodate a nearby stitching computer.
- You have staff to manage cabling, power, synchronization and stitching software.
- Spatial audio is important and the rig’s microphone arrangement is supported by the rest of your workflow.
Choose a current integrated 360 camera workflow when
- You want a documented RTMP path into a media server such as Wowza.
- You need a specified 4K output and HLS distribution model.
- You prefer to evaluate currently supported camera firmware, encoding tools and service integrations before committing to an event.
For either approach, confirm lens coverage and seam quality at the intended camera height, reserve upload bandwidth, test the complete RTMP-to-HLS path, and provide a player that recognizes 360 metadata. Do not assume that a camera’s recording resolution, advertised live mode or headset compatibility guarantees the same result in your chosen network and player.
What viewers need to watch
On a phone or desktop, the player should allow drag, mouse or gyroscope navigation around the sphere. In a VR headset, the same 360 stream must be rendered by a headset-compatible application or browser player. HLS is a delivery format; it does not by itself create head tracking, stereoscopic depth or a headset interface. Those capabilities come from the player and the viewing device.

The Bottom Line
The Orah 4i explains how a tiny camera body can capture live 360 video, but the practical broadcast is the whole chain: camera, stitching and encoding, RTMP ingest, CDN delivery and a 360-capable HLS player. For a currently documented example, Wowza uses the Insta360 Pro 2 at 3840×2160 and reports roughly 10–15 seconds of latency with its demonstrated low-latency HLS configuration.
