SRT Server Core

Receives SRT (caller or listener, with AES encryption) and RTMP or RTMPS signals from remote encoders —vMix, OBS or hardware units— and turns them into NDI 6 sources for your production software.

Each channel has its own delay, which you change live frame by frame. Sync the cameras by hand or with your phone. If an encoder changes resolution or reconnects, the channel carries on by itself; if it drops, it restarts.

It includes a preview of the channels and of any NDI or OMT source on the network with audio meters, and a statistics monitor with CPU, GPU, network and machine capacity.

  • Up to 8 SRT channels + 1 RTMP or RTMPS
  • SRT with AES encryption · RTMP with stream key
  • Multi-camera MPEG-TS and live resolution changes
  • Preview with audio meters and statistics monitor

Phone-based sync

Open on your phone the page the App shows you (with a QR code) and hold it in front of each camera for a few seconds: it flashes a color every second and shows the PC's time, which the server recognizes on every signal. The App measures each camera's offset and suggests the delays; you apply them with one click.

Without a phone, a hand clap or a clapperboard in front of the cameras also works.

  • Frame-accurate, no cables or extra hardware
  • Works with encoders on 4G/5G
  • Fine ±1 frame tuning per camera

Intercom

Low-latency full-duplex audio between the control room and up to 16 camera operators, right from the phone browser. Push-to-talk, groups, Cue with one camera, camera-to-camera voice (CamVox), program listening and individual return for each operator.

It works out of the box on the local network. Over 4G/5G you need a TURN server: the App gives you the command to set it up in 15 minutes.

  • Up to 16 operators, in groups
  • Noise reduction and noise gate
  • Talk key anywhere in Windows
  • No apps to install

Tally Web

vMix, Blackmagic ATEM or Roland tally state, in real time, on each operator's phone: red on program, green on preview, with vibration and a warning if the switcher is lost. Nothing to install.

  • Up to 16 cameras
  • Instant on the local network

TC Record

Synchronized multicam recording with SMPTE timecode from NDI sources, USB capture cards and OMT, in MP4, MOV or MKV. When you finish, export the sequence and the multicam to Premiere Pro and DaVinci Resolve, frame-synced and with the master audio on the first track.

Includes the vMix, Roland and Blackmagic ATEM loggers: they log every cut of the show so the edit builds itself. With Sequence layout you decide what goes on each track, and after a power cut you recover the session when you reopen it.

  • H.264 or H.265 · MP4, MOV or MKV
  • Premiere (sequence and multicam) · DaVinci Resolve · EDL

Web Streaming

Shows any NDI source in any browser —phone, tablet or Smart TV— with very little delay. Perfect to monitor the feed from another room or to let your client watch the live show.

Pick the quality for 4G or Wi-Fi and each phone switches by itself to the quality its connection can take. It prioritizes delay: video only. For return audio, use the Intercom.

  • Up to 480p, with automatic quality
  • Up to 12 viewers
  • iOS, Android and Smart TV

Ports

The installer opens ports 9000–9050 in the Windows firewall, and the «Open the channel ports in the firewall…» menu adds your channels' ports (including 9443 for RTMPS). If there is a router in front, forward to the production PC the ports of the channels that come from outside.
