OAK-D S2 PoE¶
Overview¶
The OAK-D S2 PoE is the Series 2 version of the OAK-D-PoE. The main difference is that the OAK-D S2 PoE has a smaller enclosure and is therefore lighter.
It also has industrial M12 PoE connector (instead of RJ45) and additionally features M8 connector for IO connectivity; USB2 (D+, D-), camera IOs (FSIN, STROBE), power, and one auxiliary GPIO.

Hardware specifications¶
This OAK camera uses Power-over-Ethernet (PoE) for communication and power. It offers full 802.3af and Class 3 PoE compliance with 1000BASE-T speeds (1 Gbps). A PoE injector/switch is required to power the device. It also features an IP65-rated enclosure.
Camera module specifications¶
You can select either Fixed Focus (FF) or Auto Focus (AF) color camera, more information here.

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
Connectors¶
M8 aux connector has 8pin female A-coded connector and the M12 ethernet has 8pin female X-coded connector.

Cameras also include an M8 connector cap for waterproofing in case the M8 connector wouldn’t be used.
External triggering: Sensors require 1V8 rising edge on FSYNC for the trigger event. We are using an optocoupler and ESD protection diode, so the input trigger voltage should be 12V (up to 24V) and the trigger logic is reversed, so trigger event happens at 0V on the FSYNC line. For an example, see External FSYNC Example.
Stereo depth perception¶
This OAK camera has a baseline of 7.5cm - 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 depth range: 70cm - 12m
MinZ: ~20cm (400P and extended), ~35cm (400P OR 800P, extended), ~70cm (800P)
Median depth accuracy (See 800P, 75mm baseline distance OAKs for details):
below 4m: below 2% absolute depth error
4m - 7m: below 4% absolute depth error
7m - 10m: below 6% absolute depth error
Integrated IMU¶
This OAK camera has an integrated BNO085, a 9-axis IMU (Inertial Measurement Unit). See IMU node for the API details on how to use it.
Note: due to supply chain issues, most of the OAK camera that were manufactured between Q2 2021 and Q2 2023 have integrated BMI270 - 6-axis IMU instead.
Power consumption¶
Most of the power is consumed by the RVC2, so the power consumption mostly depends on the workload of the chip:
Base consumption + PoE circuitry + camera streaming: 3W - 3.5W
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 ~5.5W 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).
To find out more, see our Operative temperature range documentation.
Vibration Testing¶
This OAK device has been tested for vibration tolerance according to the EN 60068-2-6:2008 standard:
Vibration Report - Report of the vibration stress tests performed by the SIQ (3rd-party lab)
Vibration Results - Results of Camera Focus, Camera Angles, and Stereo Depth Accuracy before and after the vibration stress tests
More information can be found at Vibration Tolerance documentation.
Operational Temperature¶
This device is rated to withstand temperatures within the range of -33° C - 55° C. Use in temperatures outside of this range may result in device failure.
