When Google Chrome sends a notification saying that it could not find hardware, check the following things:
- Are your webcam and microphone plugged in and switched on? You can check this by opening Skype, for example, and test if the camera and microphone are working.
- Have you given permission for the use of the webcam and microphone?
Check this by starting a role play and then clicking on the camera icon in the upper right corner. It’s important that you have checked the box always give TrainTool permission to use the webcam and microphone.
After you have changed these settings, refresh the page and the webcam and microphone should be working.
3. Temporarily disable firewall
Sometimes it might occur that there is no hardware to be found even though you have done everything right so far (your webcam is plugged in, you've given permission to use your webcam, you are using the right browser,..). A possible culprit for denying access to your webcam is an intrusive firewall.
Searching for your antivirus program:
When using the Windows operating system you can usually find your active antivirus program on the bottom right on your taskbar next to the icons for your battery, sound, and wifi.
If this is not the case, you can try to right-click on the arrow pointing up that shows your hidden icons (picture below shows an example of how this might look like). As you can see in the example, the antivirus program 'Windows Defender' is active on this computer.
If you are sure that you have an antivirus program running, but you can not find it with one of the previously described methods, you can always use the search option on your computer.
(Temporarily) Disabling your firewall:
Important: Disabling your firewall only temporarily is a good habit. This will ensure that you can not forget to turn it on again. Turn off all your programs that you do not need at the moment and make sure that the only website that is open in your browser is TrainTool's. This is because your computer can encounter dangerous malware and viruses when navigating unsafe websites.
You can temporarily disable your firewall by right-clicking on the icon of the antivirus program. Usually, you will see the option to (temporarily) disable the firewall between the listed options that appear when right-clicking on the icon. If this option is missing from your listed options, you will have to open the antivirus program to disable the firewall in the settings (see an example below with the Avast antivirus program).
To see if disabling your firewall worked, you will have to refresh TrainTool in your browser.
Result 1: Webcam still not working.
Try the next step (4).
Result 2: The webcam is working.
Success! One more thing though:
It is not advised to turn your firewall off every time when using our program. That's why it is a good idea to go to the configuration of your firewall to adjust the specific setting that is causing trouble when trying to access your webcam. If you do not know how to do this it would be wise to contact your system administrator or the support team of the antivirus program itself. They should be able to help you out.
4. Not working yet?
If for some reason you can not get it to work, you can try using a different browser like Firefox or Internet Explorer. Or try rebooting your computer. And did you know that we have a mobile app available on the Apple App Store and Google Play Store?
