Setup
Follow these steps to set up your FoMaKo K820S PTZ Camera:
- Power Connection: Connect the provided 12V 2A power adapter to the DC 12V port on the camera. Alternatively, if using PoE, connect an Ethernet cable from a PoE-enabled switch to the LAN port.
- Video Output: Connect your preferred video output cable (12G-SDI, HDMI, USB3.0, or Ethernet for NDI/LAN) to your display, capture card, or streaming device.
- Network Connection: For NDI/LAN control and streaming, connect an Ethernet cable to the LAN port. Ensure your network is properly configured for IP communication.
- Audio Input: If external audio is required, connect an audio source to the LINE IN port.
- Control Connection: For external control, connect an RS232 or RS485 cable to the respective ports, or use the network connection for IP-based control.
- Power On: Flip the ON/OFF switch to the 'ON' position. The camera will perform a self-test and the LCD screen will display its IP address and resolution.
