OAK-D SR¶
Overview¶
The OAK-D Short Range (OAK-D SR) was designed to provide an accurate close-in depth perception. It’s ideal for application like bin picking/pack, for pick and place machines, quality control/automated manufacturing, robotics arms, and more.
It has two OV9782 global shutter color cameras, that are used as the stereo pair.
The OAK-D SR leverages our OAK-SoM-Pro to make a overall compact design. The use of the SoM reduces the design’s scale, making it easier to mount or fit in various robotic processes. The design is also open-source, allowing for any necessary modifications. The data is output to a host USB 3.1 Gen1 (Type-C).
Hardware specifications¶
This OAK camera uses USB-C cable for communication and power. It supports both USB2 and USB3 (5Gbps / 10Gbps).

RVC2 inside¶
This OAK device is built on top of the RVC2. Main features:
4 TOPS of processing power (1.4 TOPS for AI - RVC2 NN Performance)
Run any AI model, even custom-architectured/built ones - models need to be converted.
Encoding: H.264, H.265, MJPEG
Computer vision: warp/dewarp, resize, crop via ImageManip node, edge detection, feature tracking. You can also run custom CV functions
Stereo depth perception with filtering, post-processing, RGB-depth alignment, and high configurability
Object tracking: 2D and 3D tracking with ObjectTracker node
Stereo depth perception¶
This OAK camera has a baseline of 2 cm - the distance between the left and the right stereo camera. Minimal and maximal depth perception (MinZ and Max) depends on camera FOV, resolution, and baseline- more information here.
Ideal range: 30cm - 100cm
MinZ: 20cm (800P)
MaxZ: ~3 meters with a variance of 10%
Note that if you don’t need accurate depth perception below 70cm this OAK camera might not be ideal for your application.
Power consumption¶
Most of the power is consumed by the RVC2, so the power consumption mostly depends on the workload of the VPU:
Base consumption + camera streaming: 2.5W - 3W
AI subsystem consumption: Up to 1W
Stereo depth pipeline subsystem: Up to 0.5W
Video Encoder subsystem: Up to 0.5W
So the total power consumption can be up to ~5W if you are using all the features at 100% at the same time. To reduce the power consumption, you can reduce FPS of the whole pipeline - that way, subsystems won’t be utilized at 100% and will consume less power.
Operating temperature¶
The ambient operating temperature of RVC2 based devices is between -20°C and 50°C when fully utilizing the VPU.
Similarly to the Power consumption, max operating temperature depends on VPU utilization. The higher the VPU utilization, the more heat the VPU will generate. The RVC2 VPU can continuously operate at 105 °C, after which the depthai library will automatically shut down the device (to avoid chip damage).
