OAK-1 MAX¶
Overview¶
OAK-1 MAX supports up to 32MP color camera resolution (IMX582) on a tiny, yet performant, device.
OAK-1 Max isn’t a standard USB camera. It’s a 4-trillion-operations-per-second AI powerhouse that performs your AI models on-board, so that your host is free to do whatever you need it to do.

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 - 4K/30FPS, 1080P/60FPS
Computer vision: warp/dewarp, resize, crop via ImageManip node, edge detection, feature tracking. You can also run custom CV functions
Object tracking: 2D tracking with ObjectTracker node
IMX582 RAM consumption¶
At highest resolution, the IMX582 image sensor produces 32MP frames, which can consume a lot of RAM. As OAK cameras are embedded devices, they don’t have a lot of RAM to begin with. In most pipelines, even just the ColorCamera node with default pool sizes will be too large, so you need to be very cautious when it comes to RAM and we suggest reading the RAM usage documentation. For ColorCamera node, you’d likely need to change pool sizes, example here:
cam = pipeline.create(dai.node.ColorCamera)
cam.setResolution(dai.ColorCameraProperties.SensorResolution.THE_5312X6000) # 32MP
# Decrease pool sizes for all outputs (raw, isp, preview, video, still):
cam.setNumFramesPool(2,2,1,1,1)
IMX582 HDR¶
IMX582 sensor supports on-sensor HDR, so it can be leveraged by the Robotics Vision Core 2 as well. In the comparison image below we are using OAK-1 MAX. HDR support is currently on branch camera_controls_misc and will be merged to main soon.

For the HDR image above we used the following argument for cam_test.py:
python3 cam_test.py -cams rgb,c -rs -cres 12mp -fps 10 -misc hdr-exposure-ratio=4 hdr-local-tone-weight=75
3D models¶
Compared to OAK-1 Lite, OAK-1 Max only has a different camera sensors, otherwise PCBA/enclosure is the same.
