Bellus3D ARC camera
Windows 10 computer with Intel Core i3, M3 or above processor, 4GB of RAM, 100MB or more of free disk space
Tested host PC: Surface Pro 7 and Surface Go 2 M3
The ARC camera is powered by USB.
A single ARC camera can be plugged in to your computer’s USB3.1 port directly provided that your computer can supply 5V/1.2amp of power. You may need a Type C to USB3.1 Type A female adaptor if your PC doesn't have a USB 3.1 Type A port and only has a Type C port (e.g. Surface Go 2 M3). You will need a powered USB hub if your computer cannot supply sufficient power via USB or you need to connect more than one ARC cameras to your host computer:
USB Hub for ARC-4 (4 cameras): 7-port, 35W or more powered adapter
USB Hub for ARC-7 (7 cameras): 10-port, 60W or move powered adapter
ARC-1 (Single Camera): No special mounting hardware required. The camera includes a ¼ inch thread for mounting on a tripod.
ARC-4 or ARC-7 (Multi-Camera System): Special mounting frames required and are available from Bellus3D.
Unzip the Bellus3D ARC<version>.zip file by clicking Extract All.
Double click the Bellus3D ARC Installer <version>.exe to install.
Click Install to use the default location (“C:\Program Files\Bellus3D\ARCHost”). Or, you can pick your own installation location by clicking Browse.
The Bellus3D Host Service is a web service that requires http port 3001 to be open. If port 3001 on your computer is already reserved for another service, when you double click the launcher, follow the instructions to change the default port.
You will be prompted to upgrade your ARC camera software or firmware if necessary after you have installed or updated your ARC software on our host computer. The update requires Internet connection and may require downloading a large file so please make you have high-speed broadband connection during the update. Please note: once you update the camera software, you won’t be able to downgrade to the previous version. If you do not wish to upgrade, please uninstall the new version and re-install the previous version of ARC software.
After installation has finished, the Bellus3D ARC scan app will be opened automatically through your default browser.
Or, you should have this short-cut icon on your desktop. You can also double click it to launch your ARC Scan App.
A station is one or more ARC cameras that operate together for scanning purposes. The ARC system currently supports ARC-1 (single camera), ARC-3 (3 cameras), ARC-4 (4 cameras), and ARC-7 (7 cameras). You must create at least one station before you can start scanning.
The first time you start using ARC camera(s), you will be presented by the screen below. Please click the Create Station button below to create a station.
For creating ARC-1 stations, you can connect the camera directly to the host computer’s USB port (provided the computer can supply 5V/1.2amp of power via the USB port). For creating a multi-camera station (ARC-4 or ARC-7) or if your computer cannot provide sufficient power, you must first connect the cameras to a powered USB hub, and then connect the hub to the host computer. The cameras should show a green light when it is ready. Click the Next button.
Pick the single camera layout if you are setting up a single camera (ARC-1). For multi-camera (AR-4,7) stations, choose the camera layout that matches our camera mounting system.
You should see all the cameras connected and detected. For ARC-1 stations, as long as there is one camera ready, you will be able to continue by clicking the Next button. For ARC-4 or ARC-7, you must have at least 4 or 7 cameras connected to continue. Please note that you can configure a station with fewer cameras than what is connected. For instance, if you already have an ARC-7 station, you can create a new ARC-1 station using only the center camera, or an ARC-4 station using only the 4 middle cameras.
If any of the connected ARC cameras has not been registered, you will be prompted to register the cameras first before you can move forward to the next step by clicking Register All Cameras. You will need to provide an email address to register the cameras to. You can also register a camera under About->Registration. Internet connection is required to register your cameras.
Once all cameras are registered, you can click the Continue button to continue the creation of your station.
The host computer will attempt to connect to all cameras of the station via the USB port. If the cameras are connected successfully, a preview image will be taken from each camera and displayed in a thumbnail window. Once you see a preview image from all your cameras, click the Next button.
ARC-4 or ARC-7 Only: Position your head in front of the center camera roughly 35 cm away and keep your head in the middle of all the cameras. Press “Refresh Cameras” to update the camera preview images until your head appears in all the cameras. Manually drag the corresponding camera preview image to match the correct camera layout and head orientation.
If your bottom camera is installed horizontally, please use the Rotate button next to the image to adjust the preview to the correct position.
Click the Finish button and enter a station name to save your station with.
Station Manager is used for managing your configured stations. You will be able to see all the stations that you have configured on this PC. Click the Configuration button then Station Manager button on the side bar to access Station Manager.
You can perform the following operations to a station as shown below:
Switch to a new station that is not currently in use by clicking the Select button
Check the station status of a currently occupied station by clicking the Status button
Rename a station by clicking the Rename button
Delete a station that is not currently in use by clicking Delete button
Your ARC cameras have been calibrated in the factory and should be ready for scanning. However, we recommend that you recalibrate each time you set up a new ARC station. Please follow the instructions of "How to Recalibrate" to recalibrate the ARC cameras, or if you are seeing poor 3D scan results
You can create a Bellus3D Face Cloud account to upload your models to the cloud. An Internet connection is required and your computer must be able to connect to the Bellus3D server to create a new account.
Click the Setting icon to open the sidebar, then click the Face Cloud button.
Click the registration link below and follow the instructions to create a new Face Cloud User Account. If you have created a Face Cloud account previously, click Sign In instead.
New account signup requires email verification. After signing up, please check your email inbox for a verification email from Bellus3D (or check your spam folder if you cannot find the email in your inbox). Please click the link in that email to verify your email address and activate your account.
If you have enabled “Auto upload model to Face Cloud” in the Face Cloud menu of Settings sidebar, your models will be automatically saved to your Face Cloud account so you can access them later from a web browser and you do not need to export the files locally after each scan (although you could do both.)
If you have enabled the Dental Bite Plate feature in Settings->Configuration, you will see a Dental Bite Plate button on the screen. Click to enable it and you will be presented with a dental plate icon in the oval. If the subject’s mouth is biting a dental bite plate created from a Bellus3D bite plate file, the bite plate will be processed separately from the face scan and will retain accurate details and not smoothed with the face scan. This allows more accurate alignment with other dental scan files. The feature is available for ARC-4 (FACE mode) and ARC-7 only. You can download the Bellus3D dental bite plate file from the Settings menu.
New scan button is a quick access to start a new scan session.
Click the Settings icon on the top right corner of the Home page to open the Settings sidebar.
Calibration controls the ARC camera calibration, which may be needed if the camera is producing poor 3D scans. You can press the Recalibrate button and follow the instructions on screen to recalibrate the camera when you see poor scanning results or you are not able to get the red oval to turn green in the scanning page.
You can restore to Factory Calibration by clicking on the Restore button below.
Start manual calibration by clicking on the Start button in the screen above.
Please fit you face in the green oval as shown below
Click the Recalibrate button
Once the calibration is complete, you can start a new scan from the Home page

If you see the Scan App page cannot be reached in your web browser, your ARC Host Service is probably not running. The host service automatically started when you double clicked your launcher. Therefore, you can restart the host service by clicking on the ARC Scan App desktop. Alternatively, you can manually restart the host service following the steps:
1.1 Go to the Windows start menu and start Task Manager.
1.2 Check to see if the Bellus3D ARC Service is running.
1.3 If the Service is running but you see an issue with the ARC Scan App, please click the “End task” button as shown in the picture above. Then, double click ARC Scan App launcher on the desktop.
1.4 If the host service is running but your web browser still shows http://localhost:3001 cannot be reached, you should check to see if port 3001 is open on your computer and you may need to change the default http port. Please see HTTP Port in the Installation section for details. Please make sure your antivirus software is not blocking the port.
If a camera is not connecting, please check to see if the USB cable is connected to the host computer or a powered hub. Try unplugging and replugging it back in. Make sure the host computer or the powered hub has sufficient power for all the connected cameras. If a camera can connect to the host computer but disconnects when you try to start scanning, the camera may not be getting sufficient power from the USB port. You may need to use a powered USB hub. See Prerequisites for details.
