I've got a requirement for minimum focusing distance of 4". I also have a need for minimum heat and noise. Are there any Luxonis cameras that would meet those needs while running an ML vision model on video? They would be operating in an environment that varies between 50-90 degrees Fahrenheit.

Hi @kkeller!
Based on your requirements, the OAK-D-Lite camera could be a suitable option. This camera can withstand an ambient temperature of 40°C (104°F) under full load, which is within your specified operating temperature range of 50-90 degrees Fahrenheit. However, it's worth noting that the camera images start to get noisy above this temperature, especially in dark areas. The DepthAI library will gracefully shut down when the chip reaches 105°C to prevent thermal damage.

In terms of focusing distance, the OAK-D-Lite has 2x global shutter grayscale cameras that are Fixed Focus and can see quite close (down to 10 cm). However, the minimum focusing distance for the color camera is typically around 50 cm. If you need things closer than 50cm to be in focus, you should select the Auto-Focus option when ordering the OAK-D-Lite.

Please note that the OAK-D-Lite has a "Lite" version of cameras on-board (IMX214, 2x OV7251), which are more prone to thermal noise. If noise is a concern, you may want to consider a different model.
