Thanks for mentioning the missing parts. It was so obvious that I missed it, they are now added ;)

You are right, Version 2 had a visual camera. However, the alignment between LWIR sensor and visual camera was never perfect and most people only used the thermal image feature OR they took photos with a smartphone and combined it in the Thermal Analysis Software (ThermoVision) on the PC later on. That's why I decided to remove the visual camera for V3 to reduce building complexity and costs.
