6. Installation Guide

Use outside of the specified conditions could cause the device to fail and/or function incorrectly. These conditions are applicable for the environment immediately around the device under all operational conditions. When used with an external enclosure, active temperature control and/or other cooling solutions are recommended to ensure that the device is maintained within these ranges.

6.1 Installation Recommendations

1. When using an external housing around the camera for dust proofing, use foam inserts or rubber gaskets between the front of the camera and the external housing.
2. Avoid the application of external forces to the camera chassis during the installation process.
3. Disassembling the chassis and mounting brackets will void the warranty.

6.2 Heat Dissipation

1. Avoid any direct heat sources around the camera.
2. Maximizing the space inside the external housing may help lower the operating temperature.

6.3. Transmittance Requirements

Transmittance requirements for the front cover protection lens of Femto Bolt 3D camera are listed as follows:

$$ \begin{array}{l} 835\sim 865nm T_{min} > 85\% , \ 800\sim 960nm T_{ave} > 88 \% and \ 400\sim 700nm T_{ave} > 85\% \ \end{array} $$

1. RGB transmittance:

2. RX transmittance:

$$ 420\sim 680nm T_{\min} > 97\% $$

1. Flatness of front cover lens material: < 0.005mm.

2. Glass is recommended.

Any protective glass in front of the camera must meet the above requirements.

6.4 Cable Design Guide

It is recommended to use the included USB Type-C cable. If a longer cable is needed, please select a USB certified cable that supports both power and data (1–1.5m length is recommended).

8. Field of View Illustration

The image below shows the depth and RGB camera field-of-view, or the angles that the sensors "see". This diagram shows the RGB camera in a 4:3 mode.

This image demonstrates the camera's field-of-view as seen from the front at a distance of 2000 mm. When depth is in NFOV mode, the RGB camera has better pixel overlap in 4:3 than 16:9 resolutions.

9. Multi-Camera Synchronization

Multiple cameras are used to increase camera coverage, fill in occlusions where a single camera might have blind spots or blockage, capture multiple images of the same scene from different viewpoints or angles or increase the effective frame rate. Orbbec's Sync Hubs are available in two versions, the Sync Hub Dev and Sync Hub Pro, and are designed to reduce the complexity and cost of a multi-camera network of compatible Orbbec cameras and external sensors. The trigger voltage is switchable, and the number of secondary devices can be extended using multiple hubs.

The Developer edition, compact and flexible, uses a GPIO interface, perfectly meeting rapid prototyping needs during early-stage development. The Professional edition, designed for commercial use, employs a reliable RJ45 interface, guaranteeing a more stable and longer-range signal connection using standard CAT5 or better cables

When using a Star connection, the Primary device delivers the trigger pulse simultaneously to each secondary camera or device in the network. However, each camera with an overlapping Field of View will need to be programmed individually with a delay offset from the trigger to match its sequence in capturing.

To avoid possible interference when pointing at the same direction, the minimum delay recommended is 160us for compatible Orbbec cameras. To achieve the closest exposure between 2 devices, the first pulse of the second camera should fall in the first idle period of the first camera. Though the delay between the first and second cameras can be 125μs (the width of a pulse), the recommended minimum is 160μs. This will allow interleaving the exposure periods of a maximum of 8 cameras.
