FLIR Duo™ Pro FAQs

A: Duo Pro R takes 5-26 VDC, and will consume about 12 Watts of power.

A: Duo Pro R has two choices for live video output: analog video is available on the 10-pin JST interface cable, and digital HDMI video is available from the micro-HDMI connector.

A: Yes, the Duo Pro R DOES record fully-radiometric video. There are two full-framerate 14-bit file formats to choose from: RJPEG and TIFF.

  • RJPEG – This is a 30Hz video file where every frame is an RJPEG. This file format is compatible with FLIR Tools and ResearchIR, and allows users to edit radiometric parameters such as emissivity and background temperature in post-processing. Users can download ResearchIR at www.flir.com/researchir, and watch tutorial videos on this powerful software here.
  • TIFF – This is a 30Hz video file where every frame is a TIFF. This file format is compatible with many image processing tools, such as MATLAB and ImageJ. To convert the values to temperature (Celsius), multiply the image by a factor of 0.04 and then subtract 273.15.
Neither the Zenmuse XT nor Vue Pro R record radiometric video.

A: Yes, by selecting the Video Mode you can look at either thermal, visible, or Picture in Picture (PiP) video.

A: There are two ways. The best way is to connect the camera’s three PWM controls to your receiver and set one of those up to a 3-position switch. Then you can use the FLIR UAS mobile app to assign Thermal, Visible, and PiP to the different positions of that switch. If your control radio is not connected to the camera, you can make this selection directly through the FLIR UAS mobile app. Be aware, however, that since this is a Bluetooth connection it will have short range, and the camera’s Bluetooth transmitter should be turned off before flight for safety reasons by pressing the Bluetooth button on the top of the camera.

A: The Duo Pro R allows for 8x digital zoom on the visible camera, and 4x digital zoom on the thermal camera.

A: No, regardless of what Video Mode you’ve selected, the camera will always record visible and thermal video to the on-board microSD cards.

A: The visible camera on the Duo Pro R is a rolling shutter not global or mechanical shutter.

A: Lenses cannot be swapped on these cameras. First, changing lenses requires a recalibration of the entire system, and this is not something we make available. Second, the thermal and visible cameras are synced for MSX purposes and coincide with their specific field of view.

A: Yes, but you must save MSX images from the Duo Pro R in RJPEG format.

A: There are two SD cards because some of the data types can require dedicated storage. Unless you’re capturing radiometric video, everything will record to a single card. But, if you’re capturing either RJPEG or TIFF video files, those will be written to the second card.

A: These cameras can take images about 1 image/sec, but the radiometric video records at 30Hz giving you much faster capture speed.

A: That’s hard to say for certain because of the incredible variety of drones currently on the market. At its most basic level, if your drone can be made to mechanically mount the camera, provide it with 5-26 VDC power, and not have its Center of Gravity and flight times adversely effected by the additional weight of the camera (325 grams, plus the weight of associated mounting hardware), then they should be compatible.

A: The airframes these cameras can be integrated into is determined by the sophistication you are after. Whether you need first-person-view, gimbalized/stabilized imagery, tilt capability in flight, etc. these all will impact the feasibility of integration. If the airframe can lift the weight, it is possible, but the more capabilities you are after, the more requirements are present. Many of our value-added re-sellers were selected precisely because they provide this expertise, so please contact them for further assistance.

A: The gimbal seen in the product video is the Gremsy T1, and there is also one that has just been produced by Yangda, the Sky Eye II. There could be more on the horizon, but these are the ones we can confirm work at the time the product was launched.

A: The Duo Pro R does not have a built-in battery, but can be powered with anywhere between 5-26V. More integration-heavy systems will use the airframe to achieve this, otherwise, external dedicated batteries are suitable.

A: The camera is not controlled through MAVLink, but it can receive MAVLINK data from the airframe for geotagging still images.

A: This sync signal is not yet implemented into the Duo Pro R, but it is something you might see in the future, so stay tuned.

A: 3D files are available to help those designing installations in STEP format on the Duo Pro R webpage: www.flir.com/duopro.

A: There is no need to calibrate or perform routine maintenance on these cameras.

A: These cameras come with a one-year warranty and are serviced by FLIR directly and exclusively.

A: Like FLIR’s Vue Pro line of thermal imagers for drones, Duo Pro R provides an airborne temperature measurement and imaging capability that adds significant value to all your operations. But Duo Pro R also includes an included high definition visible light imaging capability for even greater flexibility. Building and infrastructure inspections, solar panel assessments, precision agriculture, public safety, and search rescue operations are all made more efficient and effective by the use of Duo Pro R’s dual sensor drone-based imaging.
