The Intel RealSense SR305 is a compact, USB-powered 3D depth camera based on Coded Light (Structured Light) technology, optimised for short-range indoor applications in the 0.2–1.5m range. With a slim form factor measuring just 139 × 26.13 × 12mm, the SR305 integrates a depth sensor, IR laser projector, and a 1080p RGB camera into a single plug-and-play module. It pairs with the open-source Intel RealSense SDK to enable facial analytics, hand tracking, gesture recognition, scene segmentation, and augmented reality on Windows platforms — all without any external power supply.

Packing List Description Quantity Intel RealSense SR305 3D Motion Sensing Camera × 1 Stand × 1 USB Cable × 1 FAQ 1. What type of depth technology does the SR305 use? The SR305 uses Coded 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 (0.2–1.5m) but works best in indoor 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 for 0.2m 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 own IR 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 on Windows with the Intel RealSense SDK (librealsense). The open-source SDK is available on GitHub and supports C++, Python, C#, Unity, and more. 5. Does the SR305 need an external power supply? No. The SR305 is fully USB 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× M3×0.5), and uses the USB 3.1 Gen 1 Micro-B interface. Core depth parameters (range, FOV, resolution) are largely identical, but SR305 offers better integration with Intel 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 for facial analytics, expression analysis, and face detection applications. For production-grade facial authentication with anti-spoofing, Intel's dedicated RealSense ID platform 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 desktop stand with a 1/4-20 UNC tripod thread, compatible with standard photography and robotics mounts. For custom integration, use the two M3×0.5 threaded mounting points on the camera body directly.
