Dronefilmer offer a range of variations in the FLIR Tau cameras - mainly due to different lenses and every lens version comes in 9hz video (slow) or 25hz video (fast).
Here some highlights:
- Difference between Tau320 and Tau640 is pixel resolution - Tau320 is 320x256px, Tau640 is 640x512px.
- Fast or slow video (9hz or 25hz) indicates the refresh ratio.
- There are various lens sizes - for aerial applications anything above the 25mm lens would be too narrow... we recommend a 9mm - 25mm lens - field of view specs are available in the download brochure for each camera.
Any Tau320/Tau640 camera with 9hz video can be exported without export license as long as following statement is made/received and obeyed:
“These commodities may not be used in the design, development, production or use of nuclear, chemical or biological weapons or missiles”
The current lead-time on these cameras is 3 weeks.
Flir offer a full frame-rate version and slow rate version of all Tau products, the use of 9 Hz detectors has given our customers some considerable advantages such as shorter delivery times, less administration and paperwork, and the ability to rent out cameras.
Any 25hz camera will have to go through an export licensing procedure that takes around three months to complete. If it concerns a Tau320/25hz for commercial application we go through the US Commerce Department to get the export license - if it concerns a military application we go through the US State Department and follow the same procedure as if exporting weapons.
The 640/25hz camera will go through the US State Department regardless of the application.
The current lead-time on these cameras is 12 - 16 weeks.
