OAK-T leverages our OAK-SoM-Pro to make an overall compact design. The use of the SoM reduces the design's scale, making it easier to mount or fit anywhere seamlessly. The design will also be open-source when we verify the hardware design.
The purpose of the device is to be used for manufacturing, warehouse, energy efficiency, and safety monitoring.
PoE connection allows cameras to communicate to other computers via networking protocols (TCP, UDP, HTTP, MQTT, etc.). As our PoE models feature device flash memory, you can also run your programs in standalone mode. OAK PoE cameras are housed in an rugged, IP-rated enclosure, which is required for industrial and outdoor use.
We suggest following PoE deployment guide as the first steps after installation.
This OAK device is built on top of the RVC2 architecture, with main features being:
- 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 - 4K/30FPS, 1080P/60FPS
- Computer vision: warp (undistortion), resize, crop via ImageManip node, edge detection, feature tracking. You can also run custom CV functions
- Object tracking: 2D tracking with ObjectTracker node
- Connectivity: M12 PoE connector and M8 connector for IO connectivity
- Thermal sensitivity: 50mK @ 25°C and 25Hz
- Measurement range: -15°C - 150°C
- Thermal sensor resolution: 256x192
- Thermal Accuracy: ±2°C or ±2% (whichever is larger)
- Sensor type: Uncooled VOx detector
- Spectral range: 8-14µm
- Power consumption: up to 6.5W
- Industrial grade aluminum housing with Front Gorilla Glass
- 1/4" tripod mount and 75mm M4 Vesa mount
- Dimension: 80x52x46mm
- Weight: 297g (with enclosure)
The base board offers full 802.3af, Class 3 PoE compliance with 1000BASE-T speeds (1Gbps). PoE injector/switch is required to power the device. If need an injector, you can buy it here.
Camera specifications
This camera combines thermal sensor and a color image sensor.
Sensors specifications| Camera Specs | Color | Thermal |
|---|---|---|
| Sensor | IMX462 (PY154) | Tiny1-C |
| DFOV / HFOV / VFOV | 95° / 84° / 45° | 111° / 90° / 65° |
| Resolution | 2.1MP (1920x1080) | 256x192 |
| Range / Focus | 60cm - ∞ | 30cm - ∞ |
| Max Framerate | 30 FPS (2.1MP) | 25 FPS (256x192) |
| Spectral range | Visible only | 8-14µm |
| Shutter | Rolling | - |
| Pixel size | 2.9µm | 12µm |
| Lens size | 1/2.8 inch | - |
| F-number | 1 ± 10% | - |
| Effective Focal Length | 3.9mm | - |
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
- PoE circuitry: 0.5W
- Thermal sensor: up to 1W
- 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 ~6.5W 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.
Thermal perception
Thermal cameras detect infrared radiation, which is emitted by all objects based on their temperature. We use a special IR-capable lens to focus the infrared light emitted by all of the objects/scene in view, which is then scanned by an array of infrared-detector elements (“pixels”) in the camera.
| Specs | Value |
|---|---|
| Sensor part number | Tiny1- C 256 02011 X H WR |
| Measurement range | -15°C - 150°C |
| Thermal sensitivity | 50mK @ 25°C and 25Hz |
| Thermal Accuracy | ±2°C or ±2% |
| Sensor type | Uncooled VOx detector |
| Spectral range | 8-14µm |
| Operating temperature | -10°C - 75°C |
| Power consumption | <1W |
| Communication | SPI (data) and I2C (control) |
Thermal perception range is similar to color camera’s range, it mostly depends on the object’s size and temperature. For example, with you can easily detect a large building even from 1km away, but you won’t be able to detect a small animal from that distance. The following table shows the approximate thermal perception range for different object sizes:
| Object | Size | Detection | Recognition | Identification |
|---|---|---|---|---|
| Human | 1.8m x 0.5m | 200m | 50m | 25m |
| Car | 4.5m x 2m | 500m | 125m | 63m |
The DRI (Detection, Recognition, Identification) ranges are based on the Johnson's criteria, which is a standard for optical systems. Specifications are as follows:
- Detection: The ability to notice that something is there, but without the ability to identify it
- Recognition: Being able to classify the type of object (like distinguishing a car from a truck)
- Identification: The capability to specify the exact nature of the object (like determining the make and model of a car).
M12 PoE connector is used for power and GBit data transfer. Additionally M8 connector for IO connectivity; USB2 (D+, D-), camera IOs (FSIN, STROBE), power, and one auxiliary GPIO. Cap for M8 is included when connector is not used to ensure water resistance. More information can be found here.
This OAK camera has an integrated BMI270, a 6-axis IMU (Inertial Measurement Unit). See IMU node for the API details on how to use it.
