Connect Via SDI

SDI Guide← Back to Get Started

This guide covers setting up Link 4K with its 3G-SDI video output for professional and broadcast environments.

📋What you need
  • 3G SDI cable (75-ohm BNC)
  • 12V DC power supply (included) or PoE+ (802.3at) switch or injector
  • A video switcher, capture card, or monitor with SDI input
  • Optional: Ethernet cable for network control

Connect SDI​

Connect the 3G-SDI Cable

  1. Connect a 75-ohm 3G-SDI cable (BNC) from the camera's SDI output to your video switcher, capture card, or monitor's SDI input.
📋Use proper SDI cables

Standard composite or component BNC cables will not carry an SDI signal reliably. Use a 3G 75-ohm-rated cable.

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​

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).

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.

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.
