I have an application which requires measuring temperature and overlaying the visual image and the thermal image. I would like to trigger a composite snapshot (optical and thermal) from motion. I would appreciate the community’s help with a couple of questions:

1. What are the main differences between the M16 and S73 for this application.

2. Which SDK do I need if I want to generate an event showing the highest and lowest temperature and their location in the image?

Hi,  
I would be happy to discuss the details of your application.  
When is a good time next week to talk? Where are you located?  
Have a enjoyable weekend.

Thank you Bob.

For now, I am just interested in simple answers.
