Encoding settings involve the configuration of compression parameters for video and audio, including resolution, codec format, bitrate control method (such as CBR or AVBR), frame rate, GOP and more.

These settings are designed to reduce file size or transmission bandwidth while maintaining perceptual quality, making them suitable for both local storage and streaming applications.

On this page, you can globally configure parameters for the Main Stream, Sub Stream video, and audio.

Main/Sub Stream parameters are typically used for video conferencing or RTMP live streaming.

• The Main Stream is used for high-quality, high-definition main picture transmission and is the core content for viewing.
• The Sub Stream is usually for screen sharing (PPT, documents, etc.) or abackup relatively low-resolution stream switched to when the network is poor.

Resolution

The resolution can be set up to 4K@60Hz.

Encoding Method

• H.264 (AVC): Video encoding standard, balances compression rate and picture quality, good compatibility, suitable for live streaming, video conferencing, etc.
• H.265 (HEVC): An upgrade to H.264, improves compression efficiency by about 50% (lower bitrate at the same quality) but requires stronger hardware support. Suitable for 4K/8K ultra-high-definition video.

📢  **Notes**

Baseline/Main/High encoding cofigurations sequentially provide higher picture quality but requiring slightly higher computational demands.

Bitrate Control

GOP (Group of Pictures)

The interval duration between two keyframes, in seconds. Affects video error tolerance and compression efficiency.

The audio can be set to AAC (Advanced Audio Coding) format, with a maximum sample rate of 48Kbps, supporting stereo dual channels.

📢  **Important**

The IP address of the device must be on the same network segment as the camera's IP address, meaning the first three digits of the device's IP address are the same as the first three digits of the PTZ camera's IP address.

Using Static IP

Case 1: One PTZ and one MSP 325N V2

1. In this case, you can make the MSP 325N V2 match the PTZ's IP. Connect the PTZ and MSP 325N V2 with an Ethernet cable.
2. After obtaining the PTZ's IP address from its manual or control panel, go to Options on the MSP 325N V2, disable DHCP.

Manually configure the MSP 325N V2's IP address, setting the first three digits of the MSP 325N V2's IP to be the same as the PTZ's IP. Click Save after setup.

Case 2: Four PTZs and one MSP 325N V2

1. Plan a unified network segment, such as 192.168.1.x with subnet mask 255.255.255.0.
2. Disable DHCP on the MSP 325N V2 and assign it a static IP (e.g., 192.168.1.x, where x is 1–254). Save the settings and refresh the page.
3. Power on the four PTZ cameras and assign each a static IP within the same range (192.168.1.x).
4. Connect the MSP 325N V2 and all PTZ cameras (all with static IPs) to the same switch via Ethernet cables.
5. Also connect your computer to the same switch. Press Win + R, type cmd, and press Enter. Ping each device's IP address one by one—a successful reply confirms the device is reachable.

For Automatic/DHCP Setup

1. Ensure both the PTZ cameras and the MSP 325N V2 are set to obtain IP addresses automatically (via DHCP).
2. Connect all devices—including the MSP 325N V2, PTZ cameras, and your computer—to the same switch.

The router will assign IP addresses to all devices, keeping them on the same network segment.

📢  **Note**

The MSP 325N V2 supports PoE power supply. If the chosen PTZ camera also supports PoE, it is recommended to use a PoE switch. In this case, neither the MSP 325N V2 nor the PTZ requires a power adapter, simplifying wiring.

Add Stream Addresses in MSP 325N V2

If you confirm that the MSP 325N V2 and the PTZ camera are on the same LAN, this device supports accessing the PTZ camera's (pan-tilt-zoom camera) picture via standard network protocols.

To connect successfully, you need to provide the camera's streaming address.
Most stream addresses follow this general structure; you only need to replace the variables.

The IP address is the static IP you set for the PTZ when connecting it to the same network as the device, or the dynamic IP obtained from the router.

The username, password, and stream path need to be checked in the PTZ's manual.

Enter a description for the stream address, then click Save below to save the settings. Now you can enable this stream address and view the PTZ signal in the preview column on the Dashboard.
