You can reset the camera through the associated stream's settings. There are two ways to open stream settings from the Streams Dashboard (/streams):
Click on the stream of interest to reach the stream overview, then click Settings in the sidebar.
Click the hamburger dropdown icon on the stream thumbnail, then click Settings.
At the bottom of the settings, you should find a “Reset Camera” button. Once this is clicked, the camera information will be erased, except for the WiFi details which are used to generate the QR code (which is also accessible through the hamburger dropdown). The camera will then automatically reset after a few minutes, or you can physically reboot the camera by unplugging the power cable and plugging it back in. After the camera powers back on, it will begin the reset process. The camera can now be registered to a different stream - either a new one at /camera or an existing one by opening the QR code from the stream's dropdown menu.
Note: if a camera cannot find its associated stream or connect to its stored WiFi network, it will automatically reset and reboot.
When new camera firmware is available, a badge will appear next to the Settings tab of the stream overview page. Click the “Update” button next to Firmware Version in the stream settings to begin the update process. Similarly to resetting, you can manually reboot the camera to trigger the update.
