Audio & Video Settings
The Audio & Video page contains all settings related to how the SimplTrack3 encodes and outputs video and audio. It covers the HDMI/SDI output format, video encoding for three IP streams, and audio encoding configuration.
Changes to video encoding and output format settings can affect live output immediately after clicking Apply. Modify these settings during scheduled maintenance windows to avoid disrupting active streams or recordings.
HDMI/SDI Output: Encoding Settings
| Setting | Options | Description |
|---|---|---|
| Video Format | 1080P60, 1080P50, 1080P30, 1080P25, 720P60, 720P50 | Sets the resolution and frame rate of the HDMI/SDI physical video output. |
Click Apply to save changes. Click Refresh to reload the current values from the camera.
Switching the video format from HDMI to SDI requires that the camera to be rebooted for the changes to take effect.
Video Encoding Settings
Global encoding settings that apply across all IP streams.
| Setting | Options | Description |
|---|---|---|
| Encoding Profile | Base, Main, High | Sets the H.264 encoding profile. Base offers the widest compatibility with legacy devices. Main is the recommended default. Main provides a balance between compatibility and compression efficiency. High provides the best compression efficiency for modern systems. |
| Video Templates | Low, Medium, High | Quick presets that apply a balanced combination of resolution, bitrate, and frame rate to all streams. |
PTZ Stream: Encoding Settings
The primary IP stream from the PTZ camera. This is the main high-quality output used for streaming, recording, and monitoring.
| Setting | Options | Description |
|---|---|---|
| Encoding Protocol | H264, H265 | Video compression codec. H.264 provides broad compatibility, while H.265 provides higher efficiency but requires a Windows paid Windows plug-in to pull the stream in. |
| Resolution | 640x360, HD720, 1080P | Output resolution for the PTZ stream. |
| Video Frame Rate | 1–60 fps | Frames per second. |
| Bit Rate (Kbps) | Numeric | Target bitrate in kilobits per second. |
| Bit Rate Control | CBR, VBR | CBR (Constant Bitrate) is ideal for live streaming. VBR (Variable Bitrate) is ideal for recording. |
| I Key Frame Interval | Numeric | Defines how frequently keyframes are transmitted. Lower values improve seek accuracy but increase bandwidth. |
Reference Stream: Encoding Settings
The secondary stream from the wide-angle reference camera. Typically used for auto-tracking analysis and monitoring.
| Setting | Options | Description |
|---|---|---|
| Encoding Protocol | H264, H265 | Video compression codec. H.265 provides higher efficiency but requires compatible decoders. |
| Resolution | 640x360, HD720 | Output resolution for the reference stream. |
| Video Frame Rate | 1–30 fps | Frames per second. |
| Bit Rate (Kbps) | Numeric | Target bitrate in kilobits per second. |
| Bit Rate Control | CBR, VBR | Constant or Variable bitrate mode. |
| I Key Frame Interval | Numeric | Defines how frequently keyframes are transmitted. Lower values improve seek accuracy but increase bandwidth. |
Stream 3: Encoding Settings
A third IP stream available for additional monitoring, recording, or integration.
| Setting | Options | Description |
|---|---|---|
| Encoding Protocol | H264, H265 | Video compression codec. H.265 provides higher efficiency but requires compatible decoders. |
| Resolution | 640x360, HD720, 1080P | Output resolution for Stream 3. |
| Video Frame Rate | 1–30 fps | Frames per second. |
| Bit Rate (Kbps) | Numeric | Target bitrate in kilobits per second. |
| Bit Rate Control | CBR, VBR | Constant or Variable bitrate mode. |
| I Key Frame Interval | Numeric | Defines how frequently keyframes are transmitted. Lower values improve seek accuracy but increase bandwidth. |
The PTZ Stream should always be configured at the highest quality your network can support. The Reference Stream and Stream 3 are typically configured at lower resolutions and bitrates to conserve bandwidth.
Audio Settings
| Setting | Options | Description |
|---|---|---|
| Sample Rate | 48 KHz | Audio sampling frequency (fixed). |
| Audio Rate | 48 Kbps, 64 Kbps, 96 Kbps, 128 Kbps | Encoded audio bitrate. Higher values improve audio quality. |
| Line In Volume | Numeric | Controls the input level of the line-in audio source. |
| Audio Encoding Protocol | AAC | Audio codec (fixed to AAC). |
