GENERAL

Q: What is SIRAS?

A: The Teledyne FLIR SIRAS is an affordable professional drone with a swappable quick-connect payload system. It ships with a gimbaled dual camera Vue^® TV payload that includes a high-resolution radiometric thermal (FLIR Boson^®) and a high-resolution visible camera payload for industrial inspection, law enforcement, firefighting, search and rescue, and mapping missions.

Q: What does SIRAS offer that its competitors don’t?

A: SIRAS stands for Secure InfraRed Aerial System. It’s number 1 design consideration is cyber security. SIRAS does not connect to the internet, and it is not made in a nation the US government has labeled a “country of concern”. SIRAS is a closed system that cannot be hacked. All data is stored on the drone or its GCS. Updates occur by downloading new FW onto the SD card of the GCS. You can live stream the GCS display screen to a command center via the HDMI port using an Android device running DronseSense, Zoom, Teams, Live U, or Motorola CAPE.

SIRAS comes with high-performance thermal and visible cameras. It is not geo-fenced, is easy to fly, and has hot swappable batteries that can be exchanged in less than a minute. It is IP54 and can be flown in wind and rain. It’s batteries are rated to 31-minutes of flight time and it features radar-based front collision avoidance. SIRAS payloads are swappable so you don’t have to buy a new drone as new payload technologies are released.

Most importantly, SIRAS is priced less than $10,000. There is no data subscription and no account required to fly. It complies with all FAA Remote ID requirements.

SIRAS provides best-in-class imagery, mission flexibility, data security, plus compatibility with leading photogrammetry software, enabling the pros to get the job done.

Q: How is SIRAS more versatile than its competitors?

A: SIRAS provides a geofence-free flight experience and a quick-connect gimbal, so future payloads with additional features can be swapped for specialized missions. The existing SIRAS dual sensor payload includes a visible 16MP camera with up to 128x zoom to pinpoint details. In comparison to the leading drone maker, at max zoom, the EO sensor provides up to 30 percent more pixels on target.

The companion 640x512 pixel high resolution FLIR Boson infrared thermal camera provides clear imagery, 5x digital zoom, and temperature-measuring capabilities. 

Q: What is the competition for SIRAS?

A: Today, China-based companies dominate the global commercial drone market but are increasingly under pressure concerning privacy and data security issues. Domestic drone manufacturers struggle with volume production and significantly higher pricing than Chinese competitors. SIRAS provides the data security and features customers in North America require but at a price point more aligned with China-based drone makers.

Q: Why will customers choose SIRAS over foreign competitors?

A: Chinese manufactured drones have been banned in some US State and federal agencies are required to stop flying them by the end of 2025. Many private companies, especially utilities, have voluntarily grounded their Chinese drone fleets due to cyber security concerns. SIRAS is a cost-effective alternative to Chinese made drones.

There are several non-Chinese foreign made drones but these are all more expensive than SIRAS and have lower camera resolution. Customer service for these brands has been difficult as they are not based in North America.

SIRAS is from Teledyne FLIR, a North American company with decades of drone industry experience in the defense sector. SIRAS customer service is provided by Teledyne’s North American located team who typically respond to service requests and product questions within 24-hours.

Q: How and where does SIRAS store data and images?

A: SIRAS was principally designed for security. It does not connect to the internet, local Wi-Fi networks, or cellular networks. This is to prevent bad actors from accessing or viewing your identity, data and images. All data is stored in high resolution on the aircraft SD card. Low resolution data can be stored on the controller SD card.

Q: If there is no network connection, how are firmware updates executed?

A: Updates are available on the Teledyne FLIR SIRAS support site for download onto the GCS SD card.  Updates are uploaded from the SD card to the SIRAS airframe. For detailed steps on updating your drone firmware, please refer to the SIRAS User Manual.

Q:  How do I navigate to the location where the installed firmware is indicated?

A: On the SIRAS controller, open Settings (three dot icon in upper right corner of GCS display), About, and scroll down to check the firmware versions.

Q: Does SIRAS have collision avoidance?

A: Yes, SIRAS has a forward-facing radar system that is activated automatically when the return to home (RTH) feature is engaged or when manually turned on by the pilot.  The system will detect objects out to approximately 100 feet when flying at 13 mph or less.  There is no side or top collision avoidance feature. However, SIRAS has bottom-mounted sensors to detect the ground when descending and landing.  

Q: What kind of Flight Controller does the SIRAS have?

A: SIRAS was built from the ground up from proprietary components and that includes the flight controller.

Q: How does the drone fold or store?

A: The legs have clips that slide to allow them to be folded in for compact storage.

Q: How do I store the SIRAS batteries?

A: Store them in a cool, dry environment. WARNING – Do not store SIRAS batteries in an unplugged charger or in the aircraft when not in use – this will drain them 3% per day

Please refer to the SIRAS Battery Safety Guide found here for full details on how to maximize your SIRAS battery life.

Q: What accessories are available for SIRAS? Where do I buy them?

A: A hard storage case, a soft pack storage case, propellers, batteries, and additional chargers, are available from Teledyne FLIR or your dealer.

Q: The SIRAS is advertised as having a hot-swappable dual-battery configuration. Some other drones with similar features are built to be capable of limited flight to return home in the event of a single battery failure. Does the SIRAS have this capability?

A: The hot swap allows the airframe to stay on while changing batteries which eliminates the need to boot up the system again.  SIRAS will automatically fly on one battery in an emergency situation.

Q: How sensitive are the batteries to heat?

A: The suggested operating temperature is 14 ⁰F to 104 ⁰F (−10 ⁰C to 40 ⁰C).  Be sure not to recharge the batteries until they have cooled to near room temperature.  The battery charger will display an error message if the battery temperature is too high.

Please refer to the SIRAS Battery Safety Guide found here for more details.

Q: Why should I register my siras?

A: Registration allows Teledyne FLIR to quickly contact you to provide firmware updates and other important information. Teledyne FLIR will not share your registration information.

PAYLOADS

Q: Can you tell me about the payload on SIRAS?

A: The quick-connect Vue^® TV128 payload features a visible 16MP resolution camera that zooms up to 128x to pinpoint details. A companion 640x512-pixel, radiometric FLIR Boson provides sharp thermal imagery, 5x digital zoom, and accurate temperature-measurement.

Furthermore, the radiometric infrared sensor has additional analytical features including a spot meter, area measurement tool (where hottest, coolest, and average temps within the region are displayed), and isotherms. The pilot can also select their preferred color palette, such as white hot, black hot, or iron bow, among others.

Q: How does the dual sensor payload system work? Can you do side-by-side and/or one or the other?

A: The SIRAS Controller can display the IR video stream or the EO video stream by themselves or both streams side by side. In addition, SIRAS is equipped with Teledyne FLIR’s proprietary MSX technology which overlays the visible image onto the thermal This adds significant detail to the thermal image such as labeling on physical assets (e.g., storage tanks), edges of objects, and human shadows. The MSX feature is an invaluable tool to law enforcement and infrastructure inspectors.
 

Q: Do you have plans for additional payloads? If so, what is coming?

A: The Vue TV 128+ is SIRAS’s second payload. It features Teledyne FLIR’s Boson+ thermal camera for greatly enhanced thermal imagery in low contrast scenes. Other payloads are planned.
 

Q: What is the zoom factor for the visible and thermal cameras?

A: Vue TV128 payload visible camera zoom is 128x while the thermal camera zoom is 5x.

Q: Does the thermal camera have various color palettes and if so which ones?

A: Yes. Those pallets are white hot, black hot, iron bow, and others.

Q: What is the difference between 336 × 256 and 640 × 512 resolution cameras?

A: Each FLIR UAS thermal camera has an imaging detector which converts the heat energy it receives into a video image. These detectors come in 336 × 256, and 640 × 512 resolution options. The first value represents the horizontal pixel count and the second number represents the vertical pixel count. At a quick glance, many people assume the 640 is twice the resolution at a 336 but in fact, the total pixel count is 3.8x more. 336 × 256 delivers 86,016 total pixels and 640 × 512 delivers 327,680 pixels. The more pixels a camera has, the higher its resolution and the better its image quality (all things being equal). 

Q: What is the field of view?

A: Field of view, also referred to as FOV, is the angular measurement of the view the camera provides. Think of it as the size of the window you’re looking through. For example, each pixel in the 640 × 512, 13 mm configuration (45° × 37° FOV) will represent an angle of 0.07 degrees per pixel, meaning that at 100 feet, each pixel is imaging 1.57 inches.  From a less technical perspective, FOV equates to the observable area that can be imaged with the lens.

The Vue TV128 has a thermal horizontal FOV of 32° and a visible camera horizontal FOV of 67°. 

Q: Does the RGB camera usE a mechanical shutter?

A: No, it does not use a mechanical shutter.

Q: What is the thermal camera’s sensitivity?

A: The Boson sensitivity is <50 mK.

Q: What is the thermal camera’s accuracy?

A: Assuming all thermographic corrections are made accurately (e.g., emissivity and reflected apparent temperature) the thermal camera’s temperature readings will be accurate to +/-5°C when measuring temperatures between 0°C - 100°C (+/-9°F for temperatures between 32°F - 212°F).

Q: Are you developing a tethering system for this unit?

A: Yes.

Q: Is there going to be a non-thermal option? If so, is it cheaper than the current version shown?

A: Yes.

Q: Why does the thermal camera freeze periodically for a second?

IR cameras perform a NUC (Non-Uniform Correction) prior to adjusting level and span. This automatically corrects the minor detector drift that occurs as the scene and environment changes. The camera will also perform this operation on its own from time to time. Think of this as setting all the pixels back to a base reference point.

PERFORMANCE

Q: How can I start SIRAS?

A: Slowly move sticks down and in, toward you and together. Hold the sticks in this position for up to three seconds or until the motors start. Note that repeating this stick motion for 3-seconds during flight will turn off the motors and cause the airframe to fall from the sky. This is the turn off switch and should only be used in emergencies or when the airframe is on the ground.

Q: Can I fly more than one SIRAS at a time?

A: Yes, you can fly up to six SIRAS airframes in close proximity to each other.

Q: What is the flight time for SIRAS?

A: The maximum flight time for SIRAS is 31 minutes.  This is based on ideal flying conditions (no wind, fresh batteries, optimal ground speed). In general, SIRAS will fly for 25 minutes under typical flying conditions, taking the batteries down to 10 percent.

Q: What is the maximum ground speed for SIRAS?

In Sport Mode, SIRAS will achieve 38 mph ground speed in windless conditions. Maximum speed in Position Mode is 13 mph.

Q: When hovering what level of wind can SIRAS resist and maintain position against?

A: 22 mph (Beaufort Scale 5) is the official specification based on calculated values. However, SIRAS pilots routinely fly in sustained winds of 30 mph with gusts up to 50 mph. At these wind speeds, SIRAS will not fly as fast as usual, so it is best to use it in hover mode.

Q: Does SIRAS have various flight modes?

A: Yes, SIRAS has Attitude, Position, and Sport Modes.  Pilots can change between these modes in flight using the switch on the controller.

Q: How long does it take from turn on to flight?

A: SIRAS will turn on, connect to GPS satellites, and be ready to fly in about two minutes.  

Q: How long does it take to charge the SIRAS batteries?

A: Approximately 45 minutes

Q: Are the batteries hot swappable?

A: Yes.

Q: How low can you drain the batteries without damaging them?

A: Do not drain the batteries below 5%, ideally not below 10%, to maximize their lifetime. Furthermore, do not drain the batteries below 20% when flying in ambient temperatures above 80⁰F. Doing so repeated will shorten the battery life.

Q: Is there a multi-cell (more than two) SIRAS battery charger?

A: Not at this time.

Q: What are the operating frequencies of the SIRAS controller?

A: 2.4 GHz and 5.8 GHz, dual band.

Q: What is the transmission range of the SIRAS controller?

A: The maximum range under ideal conditions (no obstructions, no radio interference) is six miles.  However, ideal conditions are usually only found over water or in wide-open, flat, rural landscapes.  Pilots are urged to use good judgement when flying beyond visual line of site as interference and/or obstructions (hills, buildings) can cause loss of contact between SIRAS and its controller.  When signal is lost SIRAS will activate its return to home (RTH) feature including its collision avoidance and return to its take off point in Position Mode (13 mph). If flying BVLOS, make sure the remaining battery levels are sufficient to achieve RTH under these conditions. Generally speaking, SIRAS units can be reliably flown out to 1-mile in most (non-urban) settings.

Q: Why does this only have an 11.1 mph wind resistance?

A: This is a typo error on early release specifications. The calculated wind resistance is 22.2 mph. Practically speaking, SIRAS has been shown by our customers to fly in sustained winds of 30 mph with gusts up to 50 mph.

Q: How well does this drone perform in the high-RF environments of electrical utility inspection?

A: All such environments are different, but in use to date, once calibrated the drone performs well in these environments.  It is recommended to keep the drone close to the controller (within 300 yards) and pay attention to any magnetic interference warnings that are communicated on the controller.

Q: What's the max speed for thermal mapping compared to a drone with the Zenmuse XT2? Would it still be the ~5m/s?

This is more of a matter of best practices versus the capabilities of the hardware. The XT2 and Vue TV128 are both 640x512 thermal imagers. The capture speed would be the same as they are capturing similar imagery from your set height above target.

Q: How to Fix Gimbal Drift?

The following steps can be used to troubleshoot gimbal drift:

1. Power on SIRAS and GCS.
2. Start the Go Fly application.
3. Tap the three dots in the upper right corner of the GCS screen.
4. Select Control.
5. Scroll to and select Gimbal Calibration.
6. A pop-up message will let you know when calibration is complete.

CONTROLLER

Q: What is the default controller stick layout?

A: Mode 2

Q: How long does the controller battery charge last?

A: Approximately 200 minutes at maximum screen brightness. The GCS battery will last up to 7-hours with the screen turned down to 30% brightness. Swipe downward on the screen until the brightness display comes up and use the slider bar to adjust the screen brightness up or down.

Q: Can video and imagery from the controller be fed to external monitors?

A: Yes, the SIRAS controller is equipped with an HDMI output port. Connect the HDMI to an Android device running Drone Sense, Motorola CAPE, Live U, Zoom, or Teams to stream to a command center via the internet.

Q: What size is the controller screen?

A: The built-in screen is 2.5 by 4.5 inches, somewhat bigger than a typical mobile device.

Q: Is there a mechanism for live streaming video from the drone to a command post or multiple interested stakeholders?

A: The SIRAS controller is equipped with an HDMI output port. Connect the HDMI to an Android device running Drone Sense, Motorola CAPE, Live U, Zoom, or Teams to stream to a command center via the internet.

SOFTWARE & FIRMWARE

A: Routinely check www.flir.com/sirassupport to be sure you have the current firmware.

Q: How do I get the latest firmware?

A: Download firmware at www.flir.com/sirassupport

OBSTACLE AVOIDANCE

Q: Will or does it have all direction obstacle avoidance?

A: SIRAS has front facing radar to avoid objects in front of the aircraft and an array of sensors on the underside of the aircraft for detecting the ground.  It does not have sensors above, behind, or to the sides of the aircraft.

Q: What is the reach of the front radar?

A: 100 feet using a cone projected forward with a 38⁰ FOV.  The aircraft must fly at 5 m/sec (13 mph) or less to assure maximum effectiveness in detecting objects.  It comes on automatically during the return to home function.  Its default setting is off, but it is easily activated by pressing an icon on the controller display.  It works in both day and night situations.

Q: Can the front facing radar be turned off? Will the radar be inhibited by smoke, or prevent the UAS from moving through smoke?

A: Yes, the radar can be turned off entirely or only enabled for return-to-home failsafe purposes. Radar was selected because unlike the usual visible light sensors used for avoidance, it is not inhibited by darkness, smoke, or fog.

DATA SECURITY

Q: How is the SIRAS data secured? What certifications does it possess?

A: The aircraft has no transmission capability other than the encrypted data exchange between the airframe and the GCS. It does not provide cellular transmission, Wi-Fi, or Bluetooth capabilities (other than to comply with remote ID) to assure that SIRAS is 100% cyber safe, incapable of being hacked.

In total, SIRAS Certifications include CE mark, FCC certification, RoHS & REACH compliance, including being FAA remote ID capable.

Q: SIRAS is not subject to geo-fencing. Why does that matter?

A: Control of SIRAS is in the hands of the pilot. Public safety personnel especially need to launch quickly and get the mission completed wherever they are, as lives and property are often on the line. They cannot wait to get permission from an entity in a foreign country to fly where and when they need to. SIRAS enables pilots to launch within two minutes of power up, no questions asked, but it is the responsibility of the pilot to know where and when it is safe to fly. SIRAS is for professional, certificated remote pilots who know the rules and need to get in the air fast.

Q: Does the controller connect to the internet?

A: No, for data security reasons SIRAS has been designed to never connect to the internet.

Q: Other producers use RTK antennas to deal with interference, what about SIRAS?

A: SIRAS does not have RTK antennas as these generally require an internet connection and SIRAS was specifically designed to have no internet connection for data security purposes.

NDAA/BLUE COMPLIANCE

Q: Is SIRAS part of the Defense Innovation Unit’s Blue sUAS program?

A: No.

Q: Is the SIRAS NDAA-compliant and pre-approved for government acquisition?

A: No. SIRAS is intended for commercial missions, industrial missions, and local public safety. At this time NDAA compliance is not a requirement for this product, but we are always evaluating and open to exploring this option in the future.  

EXPORT

Q: Can SIRAS be exported to other countries?

A: SIRAS is available in the US and Canada with additional regional availability information provided at www.teledyneflir.com/siras.  SIRAS is dual use and classified under US Department of Commerce jurisdiction as EAR 6A003.b.4.b.
