2. CONNECTING THE ORBBEC CAMERA

2.1 Connecting the camera using PoE (Power over Ethernet) for power supply. 

  1. Prepare a PoE switch or a PoE-capable power source to supply power to the camera via the Ethernet (M12) data cable.

  2. Remove the protective cap from the camera's M12 port, and connect the M12 X-coded connector of the data cable to the M12 port on the camera.
  3. Insert the RJ45 end of the data cable into the PoE switch.
  4. Connect the host computer to the PoE switch using a standard RJ45 Ethernet cable (CAT 5E or higher). (For PC connection, a non-PoE port on the switch may be used.)

PoE-powered, Host without Ethernet Port

In addition to the ‘PoE-powered, Host with Ethernet port’ configuration, a USB-to-Gigabit Ethernet adapter is required and to be provided by the user.

 

2.2 Connecting the camera using a DC power supply. 

  1. Remove the protective cap from the camera's M12 port and connect the M12 X‑coded connector of the data cable to the camera's M12 port.
  2. Remove the protective cap from the camera's M12 port and connect the power cable to the camera's M12 port.
  3. Connect a 9‑24 V DC power supply to the red “POWER IN 9‑24V” pin and the black “POWER GND” pin.
  4. Insert the RJ45 end of the data cable into the host computer or into the gateway device to which the host is connected.

4. LAUNCHING ORBBEC VIEWER

 

For detailed instructions, please refer to the Orbbec Viewer tutorial video below .

5. Network Environment Configuration on the host

5.1 Linux platform

5.11 Environment preparation

  1. Prepare a Linux x86_64 / Arm64 platform with Ubuntu 20.04 or later.
  2. To ensure stable operation and optimal performance of the camera, connect the camera to a Gigabit (1000 Mbps) Ethernet port. If connected to a Fast Ethernet (100 Mbps) port, insufficient network bandwidth may result in failure to achieve expected performance and unstable connectivity.

5.12 Environment configuration

  1. The Gemini 435Le device has a default IP address of 192.168.1.10.
  2. The camera must be connected to the host via direct connection or through a switch, and the host must be in the same subnet for the device to be discovered and recognized.
  3. Once recognized, the Gemini 435Le can be accessed and controlled using the OrbbecViewer tool or the SDK.
  4. For detailed network configuration instructions, please refer to the documentation：Camera IP Configuration Function Description

5.13 Recommend Configuration

(1) If, after configuring the network environment as described in section "2", the Orbbec Viewer tool fails to recognize the Gemini 435Le network device, you should check whether the Wi-Fi connection is enabled. If Wi-Fi is enabled, it needs to be turned off first. Then, re-enable the local network connection or power cycle the network device, and it should be recognized.

(2) Due to differences in system networks and power management across platforms, packet loss may occur to varying degrees during the process of stream capture on the host machine, which can result in the frame rate not meeting expectations. Therefore, before using the Gemini 435Le device on different platforms, it is essential to configure and verify the platform and system settings to avoid issues like frame loss.

Firewall Configuration:

The firewall on Ubuntu is disabled by default. Ubuntu uses Uncomplicated Firewall (UFW) as the default firewall management tool, and UFW is disabled by default. If it is enabled, the user needs to manually configure it to be turned off. Before using Orbbec Viewer, make sure that the firewall is disabled.

 

5.1.4 Start Orbbec Viewer Experience

Once the environment and configurations are properly set up as described in the prevouse sections, you can start experiencing the Gemini 435Le by launching the provided Orbbec Viewer tool for Linux/Arm platforms, as shown in the image below:

Open the Orbbec Viewer tool, select the Gemini 435Le network device you want to open, and click Open:

5.2 Windows Platform

5.21 Environment Preparation

  1. Windows 10 or above platforms, x64 operating system, 8/16GB or above memory;
  2. Connect directly using either the Ethernet port on the host/switch or through a USB-to-Ethernet adapter.

5.22 Network Configuration

  1. The Gemini 435Le device has a default IP address of 192.168.1.10.
  2. The camera must be connected to the host via direct connection or through a switch, and the host must be in the same subnet for the device to be discovered and recognized.
  3. Once recognized, the Gemini 435Le can be accessed and controlled using the OrbbecViewer tool or the SDK.
  4. For detailed network configuration instructions, please refer to the documentation：Camera IP Configuration Function Description

5.23 Recommend Configuration

Due to differences in system networks and power management across platforms, packet loss may occur to varying degrees during the process of stream capture on the host machine, which can result in the frame rate not meeting expectations. Therefore, before using the G335Le device on different platforms, it is essential to configure and verify the platform and system settings to avoid issues like frame loss.

  1. Computer power configuration:
