| ***Connections*** | |
| **Name** | Connection name. |
| **Stream ID** | Broadcaster input ID:
- Automatic mode (in ZEN Master or Broadcaster): leave this field blank
- Manual mode: Enter the Broadcaster Input ID |
| **Host** | Public IP address for the Broadcaster; Either:
- Use the email link from ZEN Master to populate this field
- Manually enter the public IP address |
| **Port** | Destination port (to listen to for Push streams):
- **2088** (default): Non-encrypted
- **7088**: Protected with DTLS |
| **Password** | Optional: Enter a password string to be used to authenticate Push streams to the Broadcaster. |
| **Ignore DTLS Certificate** | Enable a Push input stream to establish an encrypted DTLS connection without validating the Broadcaster’s certificate. |

| ***Video Settings*** | |
| **Codec** | Video codec:
- **H.264**
- **H.265** |
| **Profile** | Encoder compression profile:
- **Baseline** - Maximum compatibility, low latency
- **Main** - Balance of quality and compatibility
- **High** - Best quality at lowest bitrate |
| **GOP (in seconds)** | Group of Pictures (GOP) length in seconds:
- .5 - 6 seconds; Default: 2 seconds |
| **Resolution** | Video resolution, frame rate (fps), and bitrate (Kbps):
- **360p60, 1000Kbps**
- **480p60, 1800Kbps**
- **720p60, 4000Kbps**
- **1080p60, 6000Kbps**

- **AAC** |
| **Sampling Rate (Hz)** | Number of audio samples captured per second, measured in Hertz (Hz):
- **44100**
- **48000** |
| **Bitrate** | Number of bits per second allocated to audio after compression, expressed in kilobits per second (kbps):
- **96 kbps**
- **128 kbps**
- **160 kbps**
- **256 kbps** |
| **Stereo Mode** | Enable stereo mode. |
| | |
| ***Network Settings*** | |
| **Latency (ms)** | Set the maximum latency (delay) in milliseconds. Larger values provide additional protection against network loss.
- 100 - 8000 ms |
| **WiFi+Cellular Bonding** | Enable Wi‑Fi + Cellular Bonding:
- Packets are sent over both networks in parallel
- The Broadcaster recombines them into one clean stream
- If one network degrades or drops, the other keeps the stream alive |
