The Intel RealSense SR305 is a short-range coded-light depth camera for indoor scene segmentation, gesture research, and desktop 3D capture. Its SR300-family sensing module project s an infrared pattern and derives depth over an optimal 0.2-1.5 m range, including scenes with little visible light.The camera offers 640 x 480 depth at up to 60 fps, IR output at up to 200 fps, and a separate 1920 x 1080 RGB stream at 30 fps. These are stream-specific modes rather than a promise that every maximum operates simultaneously. SR305 belongs to the legacy SR300 software family, so plan around a validated SDK release rather than assuming current RealSense binaries still support it.For reproducible development, start from the legacy RealSense SDK 2.50.0 baseline and verify the camera firmware, host system and wrapper versions together. Current SDK releases focus on newer devices and should not be assumed compatible with this retired camera family. Keep the tested software environment with the project.Features Coded-light projection - The IR projector provides the pattern needed for short-range depth sensing, including low-visible-light indoor scenes. Fast IR observation - Separate IR profiles reach 200 fps at VGA for image-processing experiments; this is not a 200 fps depth specification. Exposure-aware depth - Fast VGA uses interpolated HVGA at short exposure. Select the motion-range setting according to the detail and motion required. Legacy SDK planning - Keep a reproducible SR300-compatible installation. SDK 2.50.0 provides a historical validated baseline for this device family. Depth stream selection - 640 x 480 at up to 60 fps; Fast VGA uses interpolated HVGA at short exposure. Choose a profile that the host can sustain alongside the required color and motion streams. Color information - 1920 x 1080 at 30 fps; 1280 x 720 at up to 60 fps. Use intrinsic and extrinsic calibration when converting pixel coordinates or generating textured point clouds. Clear sensor configuration - This model does not include an IMU. Add a separate motion sensor or choose an inertial-equipped camera if the project needs that data. Compact physical integration - 140 x 26.1 x 12 mm (camera only) housing; 70 g (camera only). Allow clearance for connectors, cable bend radius and the optical field of view. Developer tooling - Use the compatible RealSense Viewer and SDK examples to inspect streams, record datasets and check calibration before integrating a custom application. System-level validation - Test representative target materials, illumination, motion, host bandwidth and thermal conditions before relying on measurements in an operating robot.

Gemini 2 is a newer active-stereo RGB-D option with an IMU and higher depth resolution; D405 is a passive stereo option for a much closer 7-50 cm ideal range.Compare the stated resolution, working distance and sensing mode together. FOV and depth range vary with configuration and scene conditions; changing camera brands also requires checking drivers, coordinate frames, calibration, cabling and mounting.Application.rs-app-grid{display:grid;grid-template-columns:repeat(2,minmax(0,1fr));gap:16px 24px}.rs-app-card{display:grid;grid-template-rows:subgrid;grid-row:span 3;gap:0;margin:0!important}.rs-app-card .rs-app-frame{aspect-ratio:16/9;display:flex;align-items:center;justify-content:center}.rs-app-card img{width:100%;height:100%;object-fit:contain;margin:0}.rs-app-card h3{margin:14px 0 8px!important;line-height:1.35}.rs-app-card p{margin:0!important}.rs-app-text h3{margin:20px 0 8px}.rs-app-text p{margin:0 0 12px}@media(max-width:640px){.rs-app-grid{grid-template-columns:1fr}} Facial geometry and presence research Capture nearby RGB and depth for host-side face analytics or presence detection in controlled indoor setups. Do not treat the SR305 as a certified biometric or anti-spoofing authentication device. Hand and finger tracking experiments Use short-range depth or high-rate infrared frames as inputs to a tracking algorithm. The IR stream's 200 fps maximum does not mean depth measurements are produced at the same rate. AR and foreground segmentation Separate nearby objects from the background using color and depth for interactive overlays, kiosk prototypes, or visualization. Software must handle holes, occlusions and differences between image coordinate systems. Desktop 3D scanning Collect nearby object geometry within the 0.2-1.5 m working range. Choose exposure and the Fast VGA setting carefully because motion-oriented modes change the effective spatial detail. Low-visible-light vision studies The built-in IR projector enables depth sensing without strong visible illumination. This does not guarantee usable color imagery in the dark, and competing infrared sources may interfere. Legacy robotics and HCI development Maintain existing SR300-family applications or reproduce experiments with a known compatible SDK, USB host and firmware. Confirm the software path before adopting the device in a new long-lived design.

D405 uses passive stereo for a much closer 7-50 cm ideal range and has no IR projector.How does it compare with Orbbec Gemini 2?SR305 uses projected coded light for nearby indoor scenes. Gemini 2 is a newer active-stereo RGB-D option with an IMU and higher depth resolution; D405 is a passive stereo option for a much closer 7-50 cm ideal range. Compare the profile-specific parameters in Product Comparison before changing hardware or software.What depth resolutions and frame rates are available?640 x 480 at up to 60 fps; Fast VGA uses interpolated HVGA at short exposure. Maximum resolution and maximum frame rate are not necessarily available in the same profile; query the connected device in a compatible Viewer or SDK.How close can the camera measure?The optimal working range is 0.2-1.5 m.Can this camera be used outdoors?SR305 is optimized for indoor or controlled lighting. Its infrared pattern can support depth in low visible light, but strong ambient infrared can interfere.Does the camera include an IMU?No. This model does not include an IMU. A separate motion sensor or an inertial-equipped camera is needed when the application requires accelerometer and gyroscope data.Which software and ROS setup should I use?Use a legacy-compatible SDK and firmware stack. Version 2.50.0 is the last validated RealSense SDK baseline for the retired L515/SR300 families; newer releases should not be assumed compatible. Match ROS wrapper and host versions to that SDK.What should I check for a multi-camera setup?Coded-light projectors may interfere when several cameras view the same scene. SR305 stream timing support is not a guarantee of interference-free multi-camera operation.How is the camera powered?The camera takes power from its USB connection. Use a suitable data-capable cable and a host port with adequate power and bandwidth; hubs, extensions and multiple cameras should be tested under the full stream load.What is included in the package?The package contains 1 Intel RealSense SR305 3D Motion Sensing Camera, 1 Stand, 1 USB Cable.
