Because who wants to sit by the computer?
There are a few ways to trigger the cameras using a wireless remote with Xangle Camera Server. For any of the solutions below, you'll have to hold down the trigger button for at least half a second before you release it (this is to put the cameras in a ready-state)
1- Windows / USB-hubs architecture
1.1 - Powerpoint presenter
Here are 3 different models that work properly:
- LNKOO RF 2.4GHz Finger Ring - https://amzn.to/35LLgL9This is my current best option. It is easier to get than the Kokuyo one, and the "Next" button works correctly.
- Kokuyo Power Point Operation for Finger Presenter Obsidian Kokuyoseki Ela-fp1 - https://amzn.to/2FFHAQzThis one works well and I've been using it a lot, but the "next" button doesn't fire the "press-down" event in Windows, making it a bit less flexible
- LNKOO Powerpoint Clicker Flip Pen Wireless 2.4 GHz RF PPT Controler Presentation Pen - https://amzn.to/2Rb3r7t
1.2 - Gamepad
This is the most reliable / solid option! But... it's a bit bulky! Use the "b" key to trigger. Here's my favorite one in this category: 8Bitdo M30 2.4G Wireless Gamepad - https://amzn.to/2ThOHGz
1.3 - Smartphone
From the computer, on the dashboard, scan the QR code using your smartphone. This is going to open the dashboard on a browser on your phone. From there, you can trigger using the same usual button. You'll need to be on the same network as your computer to make this work
2- Raspberry Pi architecture
Same as all of the above except these three points
- Connect the usb dongle (gamepad or powerpoint presenter) directly to any of the Raspberry Pis. You'll need to restart the Pi after you connect the dongle.
- Once the dongle is connected to a Pi, you can trigger the cameras no matter if the app has the focus or not (it becomes totally independent)
- On the Pi architecture, you also have the option to use a wireless mouse. Connect the dongle to a Pi and simply use the left button to trigger the cameras
