Can I/my guests use Zencastr on my mobile phone/smartphone/iPhone/Android phone? What about my tablet/iPad?

At this time, Zencastr doesn’t support mobile devices. We hope to in the future.

Why do I/my guests need 10GB of free hard drive space?

If you are recording in the ‘Record Audio and Video’ mode or the ‘Record Audio, Show Video’ mode, 10GB+ of free hard drive space is required. Zencastr saves a local backup of each of your and your guests’ recording files on a portion of your computer’s hard drive allotted for web browser applications. These backups allow you and your guests to recover your files in the event there is an issue with the upload to the cloud. Having at least 10GB free helps ensure that Zencastr has the necessary space to save the backups. This is especially important if you plan to record video.

What if I/my guests are recording audio only?

If you and your guests are recording in the ‘Record Audio, No Video’ mode it is still required that you access Zencastr from a laptop/computer in a supported web browser and it is strongly recommended that your operating system is up-to-date to the above minimums and that your internet connection is at least 5 Mbps. However, not using video does lower the required computer specs. For recording audio only, 2GB+ of free hard drive space (versus 10+ GB for viewing and/or recording video) and 4GB+ of RAM (versus 8 GB+ for viewing and/or recording video) is required.

Why shouldn’t I/my guests open Zencastr in incognito/private mode?

Opening Zencastr in incognito mode prevents us from being able to save local backups of your recording files. If there is an issue with the upload of the files to the cloud, it will be impossible to recover your files from the local backups if the incognito window is closed. Therefore, using Zencastr in incognito mode is strongly discouraged.

How do I check if my internet is fast enough?

Run a speed test. Upload or download speeds under 5 Mbps could cause connection and/or upload issues. Upload and download speeds of 10 Mbps or more are recommended for the best experience.
