Serv 4K Quick Start Guide

Updated on

Serv 4K lets you securely stream live camera feeds and instant recordings to anyone, anywhere, on or off set. See what the camera, editor, and colorist see—from production through final color. Serv 4K can encode up to 4Kp60 video with stunning 10-bit 4:2:2 image fidelity, can stream to up to 20 local viewers when connected to a WiFi network in Client mode (10 viewers when using Serv 4K in AP mode) when using VUER, and can be connected to Teradek’s Core Cloud Platform for even more flexibility.

You can use the front panel interface, web UI, or Serv App to control and configure Serv 4K to connect to a network.

Connect to a WiFi Network

Serv 4K supports two wireless modes: Access Point (AP) Mode (for connecting directly to Serv 4K using WiFi) and Client Mode (for normal Wi-Fi operating and connecting to your local router).

NOTE: Serv 4K can stream to up to 20 clients when connected to a Wi-Fi network in Client mode, or 10 when using Access Point (AP) mode. The number of connected devices is based on streaming bitrate.

1. Connect your phone or laptop to Serv 4K’s access point, Serv-4K-XXXXX (XXXXX represents the last five digits of your Serv 4K’s serial number), then enter the default IP address in your web browser.

2. To switch to Client Mode: From the Serv App or web UI, navigate to the Network settings, select WiFi/Wireless, then switch to Client Mode. From the front panel, press the Menu button to navigate to the WiFi screen. Press the Select/Enter button to navigate to the WiFi Mode screen, then hold down the Select/Enter button to switch to Client Mode.

3. From the Serv App or web UI, click the WiFi scan or Saved Networks tab to connect to an available network, then enter the password. Once connected, the display will list the network Serv 4K is connected to and the assigned IP address.

Connect via Ethernet

1. Connect Serv 4K’s Ethernet port (G) to an Ethernet switch or router. 

2. To confirm Serv 4K is connected, press the MENU button to navigate to the Ethernet screen and confirm the front panel status reads Ethernet: Connected along with the IP address. From the Serv App or web UI, navigate to the Network>Wired settings and confirm the status reads Connected along with the IP address.

3. Enter the IP address in your web browser’s navigation bar to access the web UI. 

Connect via Node II or USB Modem

1. Attach a Node II or USB modem to one or both to Serv 4K’s USB-C ports (I), then press the MENU button on the front panel to navigate to the Modem screen and verify that the modem has been detected and connected.

2. If the modem is not detected, connect your computer to Serv 4K’s AP network, then enter the default IP address in the navigation bar to access the web UI and manually configure the modem from the Network menu.

Configure Node II

1. Navigate to the Network menu and select the corresponding USB (Node II) modem. 

2.  Select the slot with the SIM you will be using (Slot 1 or Slot 2).

NOTE: Node II supports most provider's SIM card 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. Enter altanwifi (for Telna SIM cards intended for use in the United States) or internet (for Telna SIM cards intended for use in Europe) into the selected slot's APN field (Slot 1 or 2). 

4. Ensure that both Configuration mode and Authentication method are set to Auto.


Serv 4K encoders have a 1/4”-20 threaded hole on the bottom for mounting. Additionally, you can install dual mount pro battery plates on your Serv 4K, allowing you to attach your unit to either the back of a camera or monitor.

  • Mount the Serv 4K onto the back of your camera keeping the antennas clear of any obstructions. 
  • For best results, orient the encoder so it has clear line-of-sight.


Serv 4K encoders support recording to an SD card or NFS drive. Each recording is saved with the same resolution and bitrate set in Serv 4K. 

Record to SD card

1. Insert a compatible SD card into the corresponding slot (J).

2. From the Serv App or the web UI, enter the Recording menu, and select Enabled.  

3. Create a name for the recording, select a format, then enable Auto-Record (optional). 

Record to NFS drive

1. Click the NFS icon.

2. Enter the Host address and Share port, then click Mount.


•  Recordings are triggered manually or automatically. If Auto-Record is enabled in the Recording
, a new recording is automatically created when a streaming or camera event starts.
•  For best results, use Class 6 or higher SD cards.
•  Media should be formatted using FAT32 or exFAT.
•  If a broadcast is interrupted for connectivity reasons, recording will continue.
•  New recordings are automatically started after the file size limit is reached (FAT32).
