2.1.1 Logging in via Device Static IP

The device management page address of the MSP 325N V2 is its IP address.

Its factory default static IP is 192.168.5.100.

For first-time use, you need to set the IP of the login device (e.g., computer) to an IP in the same LAN as the MSP 325N V2's static IP, i.e., 192.168.5.x (the first three digits of the IP are the same, x is any number from 0 to 254).

Please proceed as follows:

1. Use an Ethernet cable to connect the computer and the MSP 325N V2 (if the computer lacks an Ethernet port, use a USB to Gigabit Ethernet adapter).
2. Disable the computer's current network to set a static IP address.
   1. Configure the computer's network settings: Go to System Settings > Network & Internet Settings > Network and Sharing Center .
   2. Change adapter settings > Ethernet > Internet Protocol Version 4 (TCP/IPv4)
   3. Select Use the following IP address, enter the IP address (first three digits same as MSP 325N V2's static IP, i.e., 192.168.5.x) and subnet mask (set to 255.255.255.0).

The default gateway should also be set to 192.168.5.x. After confirming the settings, the computer and MSP 325N V2 will be on the same LAN.

3. Open a browser, enter the MSP 325N V2's static IP (192.168.5.100). The default login username and password are both admin .
4. After logging in, you will enter the device management page.

It is recommended to change the account password after the first login to ensure device management security.

2.1.2 Connect the MSP 325N V2 to the Network

The MSP 325N V2's DHCP function (automatically receiving assigned IP address) is disabled by default.

After the first login using the static IP, you need to go to Network in Options to enable DHCP. This allows the device to obtain an IP address assigned by the router and access the network.

1. Power on the MSP 325N V2 and connect it to the router using an Ethernet cable.
2. Use an HDMI cable to connect the HDMI OUT interface on the right panel of the device to a display.

The display will show the IP address assigned to the device by the router .

The URL in the example below is for illustration only; please use the actual IP address assigned by your router).

On the Dashboard, you can view:

• Current system status of the device (CPU usage, memory usage, core temperature).
• Current network status.
• Connected port status.

After enabling the recording function and multi-platform live streaming function:

• REC will display the current recording duration.
• ON AIR will display the current live streaming duration.

After the MSP 325N V2 connects to a signal or input stream address, if Preview is enabled, you can preview the connected signal on the Dashboard.

On this page, you can preview all signal sources connected to the MSP 325N V2 via physical interfaces and network inputs.

Click on which signal, that signal will appear in the preview window and on the main output display device connected to the HDMI OUT port.

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.

The bitrate can be set to 128Kbps to ensure audio quality details.

After completing the configuration, you can choose Apply to Local , meaning the settings only apply to this MSP 325N V2 unit.

Or choose Apply to Group , meaning the settings will be saved to all discoverable MSP 325N V2 units on the local area network (connected to the same network as you).

• Click Apply to Group the system will automatically search and display MSP 325N V2 units on your same LAN.
• Click Start Sync to synchronize the encoding settings to these devices.

The MSP 325N V2 also supports network input as a signal source, supporting HTTP/SRT/RTMP/RTSP/NDI streaming protocols.

Enter the corresponding stream address to obtain the picture.

This page uses pulling the picture from an IP-enabled PTZ camera into the signal monitoring picture as an example.

📢  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.

On the Signal page, select a IP signal for HDMI output display.
