Prism Mobile Quick Start Guide

Updated on

Prism Mobile is the lightest LTE-enabled camera-back video encoder on the market.  With a flexible I/O and a compact, low-SWaP design, Prism Mobile easily fits into any workflow. Prism Mobile gives you 4K 10-bit HDR video transmission with integrated LTE network bonding for live coverage from any location. Prism Mobile is designed to seamlessly fit onto the back of your ENG or professional camera or placed directly on a table top. Prism Mobile can encode up to 4Kp60 video with stunning 10-bit 4:2:2 image fidelity paired with Stereo or 5.1 surround sound. The Prism platform supports many common streaming protocols such as MPEG-TS, RTSP/RTP, RTMPS, and SRT, and can be connected to Teradek’s Core Cloud Platform for even more flexibility.




  • 1x Prism Mobile Encoder

Use the front panel's menu button and navigation joystick to switch to either Wi-Fi mode or a different network. 

  1. Press the menu button to navigate to the Wi-Fi status screen and switch to Client Mode.
  2. Press the menu joystick twice in the direction indicated, then press and hold the menu joystick to switch to Client Mode.
  3. Press and hold the menu joystick in the direction indicated to scan for available Wi-Fi networks.
  4. Select an available network, then enter the password. Once connected, the display will list the network and corresponding IP address. 

Connect via Ethernet

  1. Connect one or both of Prism Mobile’s Ethernet ports to an Ethernet switch or router.
  2. Press the menu button or navigation joystick to navigate to the Ethernet 1 or screen and obtain the IP address. 
  3. Enter the IP address in your web browser’s navigation bar to access the web UI.


Prism Mobile can be remotely accessed, configured, and controlled using Teradek’s Core Cloud management and routing service. With Core, you can:

•  Bond multiple Internet connections, increasing your broadcast’s bandwidth and reliability.
•  Remotely control Teradek encoders, decoders and bonded systems from anywhere in the world.
•  Stream to multiple destinations.

Connect Prism Mobile to Core

1. From the web UI, select Cloud Services then click the Link this Device tab in the Core section.

2. Log in to Core: Enter your credentials to link Prism to your Core account, then click Next.
Link with Code: Copy the authorization code generated for your Prism, then follow the instructions provided. 

3. Once a connection is established and your Prism Mobile is listed under Sources, you can connect Prism Mobile to a server using the Core dashboard.

Connect to a Server

1. From the Sources tab, select your Prism Mobile by clicking on the name of the device.

2. Click the Connect video to Core tab, then select Streaming Server (Helios). If you haven't configured a server to your Core account, review this tutorial for steps on how to launch a new server.

3. Select a server, then click  Connect to a server

4. Under Connected Stream in the Encoder Details, click + Link Destination to connect channels or decoders to stream to.

Connect via Cellular Modem

  1. Insert a SIM card (two per Node II) into one of the Prism Mobile SIM card slots. Additionally, you can connect an external modem to either Prism Mobile USB port (G) using a 5-pin to USB connector cable. The front panel will indicate that the SIM card and modem(s) have been detected and connected to the carrier. 
  2. If the SIM card is not detected, connect your computer to Prism’s AP network (see Connect to a WiFi Network), then enter the default IP address in the navigation bar to access the web UI and configure the internal modem from the Network menu.

Configure SIM cards

1. Navigate to the Network menu and select the corresponding Modem.

2.  Select the slot with the SIM you'll use (Slot 1 or Slot 2). NOTE: Most carriers' SIMs will auto-connect, requiring no additional configuration. Additional configuration is only required when entering an APN, PIN, or authentication type. 

Node II supports most provider's SIM cards and can operate on most LTE/4G/3G data bands. With dual SIM slots, you can swap from one provider to another without needing to unplug the Node II. Only one SIM card can be used at a time.

3. If using Telna SIM cards: Enter altanwifi (for Telna SIM cards intended for use in the United States) or internet (for Telna SIM cards intended for use in Europe) in the selected slot's APN field (Slot 1 or 2). Ensure that the Authentication method is set to Auto.

If using Teradek Data SIM cards: Click the Teradek Data checkbox, then select either Native or Multi-Carrier. For Multi-Carrier, select one of the available networks.
