Connect via Network

Network Guide← Back to Get Started

This guide covers the most common setup: Power over Ethernet + Network Video + Horizon Web UI Control.

📋What you need
  • PoE+ (802.3at) switch or injector
  • Ethernet cable (Cat5e or better)
  • A computer or device on the same network

Connect Power and Network​

Choose one of the following power methods:

Option A: 12V DC Power Supply

  1. Connect the included 12V DC power supply to the camera's DC input.
  2. Plug the power supply into a standard wall outlet.

Option B: Power over Ethernet PoE+ (802.3at)

  1. Connect an Ethernet cable from a PoE+ (802.3at) switch or PoE+ (802.3at) injector to the camera's LAN port.
  2. The camera will power on automatically.
⚠️Requirement

Ensure your switch or injector supports PoE+ (802.3at), not just PoE (802.3af).

📋EEE: Energy-Efficient Ethernet

Please ensure your PoE switch or injector is NOT configured for EEE: Energy-Efficient Ethernet Mode or Power Saving Mode. These features may limit the power available to the camera, leading to unstable operation or insufficient power delivery.

Wait for Startup Sequence​

When powered, the Link 4K camera performs a startup sequence:

1️⃣
Self-calibration: During startup, the camera moves through its full range of motion while both the green (Standby) and blue (Power) LEDs are on. When self-calibration is complete, the camera returns to Preset 0
2️⃣
Ready: Once the camera stops moving and the green LED turns off, your camera is ready to use.

Find the Camera on Your Network​

The Link 4K camera supports mDNS, so you can reach it by hostname without knowing the IP address.

  1. Open a web browser on any device connected to the same network.
  2. Type the following address and press Enter:
http://ptzoptics.local/
  1. This will take you to the Horizon Web UI where you will be prompted to set up a password on your first login.
    • Default Username: admin
    • Create a strong password.
💡Multiple cameras?

Give each camera a unique Device ID from the Horizon Web UI Device Info tab. Then reach each camera by its ID: http://camera-one.local, http://camera-two.local, etc.

Control the Camera​

Use the following options to quickly verify control of the camera.

Option A: Network Control (Recommended)

If the Link 4K camera is connected to your network, you can control it from the Horizon Web UI.

  1. Open a browser and go to http://ptzoptics.local/
  2. Log in with username admin and set a password.
  3. Use the Horizon Web UI for full PTZ control, image settings, and preset management.

Option B: IR Remote (Simplest)

Use the included IR remote to pan, tilt, zoom, and save presets. Point the remote at the camera's front sensor.

Save Your First Preset​

Using the Web Interface​

  1. Move the camera to your desired position.
  2. Click Set in the Preset Control section.
  3. Enter a preset number and press Enter.
ℹ️What presets save

A preset saves both the camera position and all image settings. Calling a preset restores both.

Using a PTZ Joystick (e.g., SuperJoy)​

  1. Move the camera to your desired position.
  2. Press the Preset button on the joystick.
  3. Enter the preset number and confirm.
ℹ️What presets save

A preset saves both the camera position and all image settings. Calling a preset restores both.

Using the IR Remote​

Press [PRESET] then a number (e.g., [1]) to save. To recall, press the number again. For more information on using the IR remote, see the Using the IR Remote section.

You're Finished!​

Your Link 4K is now connected, streaming video over the network, and controllable from the web interface. You can:

  • Save more presets for different positions
  • Adjust image settings for your lighting conditions
  • Enable auto-tracking from the Automation panel
  • Configure streaming (RTSP, RTMP, NDI|HX) from the Audio & Video settings
⚠️More Information on Camera Control

This camera can be controlled using various methods and joystick controllers. To learn more about camera control, see Control Options.
