Frequently asked questions
There are several options:
- We can arrange a live demo at our HQ in San Sebastian
- We can also arrange an online (Skype) demo where we share our screen and show you how the system works. You would be able to ask as many questions as you want.
- We can contact a nearby customer or distributor who would show the system to you.
1. Visit our Contact page to get a formal quotation.
2. We will provide you with the proforma invoice and payment information.
3. After payment we will send you the system and support you.
Almost to every country. We can do it ourselves or through our distributors. We provide you with a download link for the software and the license. The rest of the hardware equipment is shipped to the address that you provide us.
2-3 weeks for most products, 4-6 weeks for certain items like external devices.
Yes. It is possible to pick up your new system directly at our HQ in San Sebastián, Spain. Kindly bear in mind that taxes will apply unless the product is duly imported in your country.
All items delivered by STT have a warranty period (one or two years, depending on the product) which is clearly stated in your offer. The warranty will cover all factory malfunctions. Take a look at our terms & conditions here.
Support and training
By purchasing your 3DMA system you get free, unlimited remote support for the installation and first trials. We want you to feel confident asap. With the instructions and tutorials provided and our supervision, your system will be up and running in no time.
The purchase includes unlimited remote assistance for the installation (we’ll supervise every step through a remote application) as well as the initial training of the user. You can also request on-site assistance, but this involves adding some cost to the quote and it is not really necessary in most cases. There are a few video tutorials for the system setup. Our technical team will guide you through the first recordings and tests until you are comfortable — no need to worry about this.
Via phone and email. We may also need to remotely access your computer in order to provide assistance. For this purpose, we will ask you to download and run . TeamViewer is a standalone remote client that will provide a secure connection between you and STT for remote control, desktop sharing, online meetings, web conferencing and file transfer.
Depending on the system there might be a problem or not. For iSen and 3DMA there would be no problem. Both software and license can be transferred to a new computer. 2DMA systems are linked to the laptop.
If your security dongle is broken, you can buy a new one from STT. The license will be updated to pair with the new dongle, and this will be done as soon as we receive the old, broken dongle. If your security dongle is lost, then you will have to buy a new software license as well.
There is roughly one major updates every year, and a few minor updates.
With the latest version, your system (if it was connected to the internet) would notify you and let you download the latest update. In any case, check out every now and then the software version log at our website and social media. Feel free to request the installer for any newer version.
No. Updates will preserve older captures and database.
3DMA Optical Systems
- CPU: Intel Core i5 (i7 preferred). It is highly recommended to have a 4-cores processor (it is mandatory for systems with 8 or more cameras).
- RAM: 8 GB (16 GB peferred).
- HD: 4 GB for installation, depending on the product. You’ll need more space for the captures database, specially if you plan to add real-time video.
- Enough free USB ports (no HUBs) for capture cameras (depends on the amount of cameras).
- OS: Microsoft Windows 10.
- Mid-range NVIDIA graphic card compatible with DirectX 12 recommended.
- If you plan to add real-time video you will need two independent USB controllers (one controller for capture cameras, one for video camera). USB 3.0 controller is required if using IDS uEye cameras or Logitech BRIO.
From 50 Hz up to 360 Hz; depending on the camera. Check the camera options below.
It depends on the movement that is going to be analyzed. Gait or cycling movements can be captured at 50-100 FPS, whereas a golf swing requires a higher frequency.
In terms of marker position tracking, its precision is directly dependent on the camera resolution and camera spacing. Based on general configurations (a 5x6m, 6-camera Sports 3DMA system or a 100FPS, 4-camera Cycling 3DMA system for instance) marker precision is <1mm, and any user has the means to check this out.
The system is calibrated with the help of a rod that has equally-spaced markers. Any time after calibration, the user can check the quality of the calibration by moving around this rod inside the capture volume and getting real-time readings of the actual distance between rod markers. This is a particular type of capture protocol in which the system just reads distances. Both the instant measurements and the moving averages are displayed. The error for these readings inside a well-calibrated volume is <1mm, and that’s a distance between pairs of markers – therefore the individual positioning error is even smaller, about half of that, in any case also <1mm.
3DMA systems work indoor with any standard light sources like halogen lamps or fluorescent lamps. There is no need to turn off the lights or work in darkness. However, you must be careful to avoid direct sunlight inside the capture area. Curtains or windows shutters will help you avoid this.
Protocols are a combination of software tools tailored to analyze a specific gesture or sport. Each protocol involves:
- a marker configuration
- a list of graphs
- relevant biomechanical parameters
- certain automatically calculated events
- a report template
All of these are carefully designed and work together to facilitate the user’s work. The goal: to move from data collection on to data processing and result display as fast as possible.
The system is calibrated only once, after the camera installation. Note that you will have to calibrate the system again if the cameras are moved. Just for the sake of maintenance, it is advisable to re-calibrate the cameras once every month.
15 minutes the first time you do it, 3 minutes for proficiency users.
It depends on the size of the room and the movement you need to analyze. A standard setting would be:
- Cycling: 4 or more cameras
- Running, golf and gait: 6 ore more cameras
- Other movements and big labs: 8 or more cameras
Typically a webcam, for instance, a Logitech c920 or Brio, but also a high-speed camera such as IDS UI-3240LE-C-HQ for a higher frequency and better resolution.
It depends on the size and form of the room, the movements that are going to be captured and the number of cameras needed. Contact us and we would help you to select the best camera configuration on your room.
- Full body analysis
- One side analysis
- Road bike measurements
- MTB bike measurements
- TT bike measurements
It depends on the room space but a standard configuration would work with 4 cameras at 100 Hz.
Yes, some of our customers set the cameras on tripods. However, it is not as practical as EDDO Biomechanics as it takes 1 hour to set everything from the beginning.
From 50 up to 240 Hz depending on the camera model. 100 Hz is the standard configuration.
No. It is an accurate tool that provides with almost all the bike fitting parameters and some references.
2DMA Optical Systems
- CPU: Intel Core i5 (i7 preferred). It is highly recommended to have a 4-core processor.
- RAM: 8 GB (16 GB preferred).
- HD: 2 GB for installation. You’ll need more space if you wish to store a large amount of videos.
- A solid state disk (SSD) is preferred but not strictly required.
- As many dedicated true USB 3.0 ports as video cameras (no HUBs, not shared with USB 2.0 devices).
- OS: Microsoft Windows 10 (64 bits).
Yes, all of those.
It does not automatically measure the bike, only the cyclist. However, the system does include manual measurement tools for distances and angles, and you can register the bike type and adjustments on each session.
Yes. Completely portable. It is not bulky and the calibration takes less than 1 minute.
The system records at 50-60 FPS or 100-120 FPS.
No. It is an accurate tool that provides with the main bike fitting parameters, some fitting tips and references.

- OS: Microsoft Windows 10.
- If you plan to add real-time video with IDS uEye or Logitech BRIO cameras, you will need a dedicated true USB 3.0 port for video camera (no HUBs, not shared with USB 2.0 devices).
Yes. The information gathered by the sensors could be exported to a CSV file (both rotation data -quaternions- and raw data -accelerometer, magnetometer…-). You can also export biomechanical curves (i.e.: the entire knee flexion-extension angle over time)
We have also developed plug-ins to receive or stream data to third-party software or devices.
The system works through a Wi-Fi network. Wi-Fi networks have a range that’s limited by the environment. A typical wireless router in an indoor arrangement might have a range of 50 meters (160 ft) or less.
Yes. You can easily plug a video camera and, moreover, iSen has been synchronized with many other devices. Check out a few options here – integrations section.
Typically a webcam, for instance, a Logitech c920 or brio, but also a high-speed camera such as IDS UI-3240LE-C-HQ for a higher frequency and better resolution.
