Application

Facial Analytics & Biometric Recognition The SR305’s optimised 0.21.5m depth range and6954 FOVmake it ideal for desktop face authentication, facial expression analysis, and user presence detection in kiosk, access control, and smart retail applications.

Hand & Gesture Tracking With up to200fps IR streaming, the SR305 captures fast, fine-grained hand and finger movements for touchless UI interaction, sign-language recognition, and in-air gesture controls in AR/VR environments.

Augmented Reality & Scene Segmentation Combined depth-and-colour data enables real-time background removal, foreground segmentation, and object detection for AR overlays and interactive digital signage.

3D Scanning & Mapping (Short Range) Developers can leverage the SDK’s scene reconstruction capabilities to create 3D mesh captures of near-range objects (e.g., small parts, face geometry) for inspection, digitisation, and VR content creation.

Research & Robotics Prototyping Lightweight, USB-powered design with open SDK makes the SR305 a popular entry point for robotics labs, HCI researchers, and embedded system developers exploring depth-based perception in short-range scenarios.

Packing List

FAQ

1. What type of depth technology does the SR305 use?

The SR305 usesCoded Light (Structured Light)technology. An IR laser projector casts a coded pattern onto the scene; the depth sensor reads the pattern distortion to calculate a per-pixel depth map. This method delivers high accuracy at short range (0.21.5m) but works best inindoor or controlled lighting direct sunlight can interfere with the IR signal.

2. What is the usable depth range of the SR305?

The SR305 is optimised for0.2m to 1.5m. Within this range it delivers its best depth accuracy. Objects closer than ~0.2m or beyond ~1.5m will either fall outside the measurable range or show reduced accuracy. For longer-range applications (>1.5m), consider the Intel RealSense D400 stereo series instead.

3. Can the SR305 work in the dark?

Yes. Because the SR305 projects its ownIR light pattern, it can capture depth data in complete darkness (0-lux conditions). The RGB camera still requires ambient light for colour output, but the depth stream is fully self-illuminated.

4. What platforms and operating systems does the SR305 support?

The SR305 runs onWindowswith theIntel RealSense SDK (librealsense). The open-source SDK is available onGitHuband supports C++, Python, C#, Unity, and more.

5. Does the SR305 need an external power supply?

No. The SR305 is fullyUSB bus-powered(~1.5W). A standard USB 3.1 Gen 1 port on your host computer or hub provides all the power required no wall adapter or separate power cable needed.

6. What is the difference between SR305 and SR300?

The SR305 is the updated successor to the SR300. Both share the same core depth sensor architecture and resolution. The SR305 features a more streamlined PCB design, improved mechanical mount points (2 M30.5), and uses theUSB 3.1 Gen 1 Micro-Binterface. Core depth parameters (range, FOV, resolution) are largely identical, but SR305 offers better integration withIntel RealSense SDK 2.0.

7. Can the SR305 be used for facial recognition or biometric authentication?

The SR305 provides the depth and colour data needed forfacial analytics, expression analysis, and face detectionapplications. For production-grade facial authentication with anti-spoofing, Intel’s dedicatedRealSense IDplatform is recommended. The SR305 is best suited for developer prototyping and research in this area.

8. How do I mount the SR305?

The SR305 includes an adjustable desktopstand with a 1/4-20 UNC tripod thread, compatible with standard photography and robotics mounts. For custom integration, use the twoM30.5 threaded mounting pointson the camera body directly.
