frequently asked questions

What technologies and brands do you use?
On this point, we are agnostic both in terms of technology and brand used. For example we use micro-bolometers from FLIR, ULIS or SEEK THERMAL (from 80×60 to 640×480) but also thermopiles from MELEXIS, EXCELITAS, PANASONIC, … This ability to choose the best imager for you (based on your needs) is one of our strengths appreciated by our customers.
I have a use case but i am not sure if it's feasible
We like that kind of question. Among our services, the feasibility study is part of our toolbox. Tell us what you want to capture and analyze as data and we will conduct a feasibility study. At the end of this study, recommendations on the best vision system to meet your needs will be presented.
How much does IT cost?
Every customer project is different, so is the price. Our approach is to provide you with the machine vision system best adapted to your needs and especially to your budgetary constraints. Our agile organization guarantees such a highly differentiated offer.
What type of spectral band do you work with?

Historically, we work with thermal infrared imagers (7-14um thermal infrared). However, our know-how also extends to the visible spectrum, the near and medium infrared. Generally speaking, we like to think differently. Let us know your needs and we will find the most appropriate wavelength(s) for the events you wish to detect.

What minimal and maximal temperatures Can you measure?
This will depend on the type of technology used and the context of use. For example, a micro-bolometer easily measures temperatures between -40°C and +550°C. On the other hand, in a severe environment (pyrometric measurement), it will be necessary to add a specific glass to protect the sensor and avoid its saturation. In short, depending on your needs, we will propose a device adapted to the temperature range you wish to measure.
Can we see through walls?
No, but focus your search on short-range radar imagery.
How far can a thermal imaging camera see?
The working distance of a thermal imaging camera will depend on three main characteristics to know:
– the field of view (the narrower the field of view, the further away you can see)
– sensor resolution (for a given field of view, a more resolved imager will identify more detail)
– sensitivity (the more sensitive the sensor, the more a distant temperature source will differ from noise)
What are the main characteristics of the thermal infrared spectral band?
Thermal infrared is electromagnetic radiation emitted by an object or living being correlated to its temperature. This spectral band is most often used for the following properties:
– day and night vision
– no active source (as with near infrared which requires scene illumination)
– non-contact temperature measurement
– non-destructive control
