ListeningCam – Audio Sensing Video Recording on Android

I have been working on an Android app that I find useful: Recording video when there are noises. I initially got the idea when I was wondering if the dog was being good when I am not home, but couldn’t find an app that does this.

Here’s a result of an early test when it was listening for the dog (Note that I’m having it save videos in tiny resolution while testing):

It’s pretty basic so far, but is still a work in progress and hopefully I’ll have something I can distribute soon.



You can view the source code at my GitHub repository.

An APK file is also available for download, but do note that there are still issues, and it may crash, require you to restart your device, etc, but here it is: http://dotslash.ca/ListeningCam/ListeningCam.apk


The video will start recording when audio level gets above the threshold, and can record for a set amount of time, or record until a certain duration of silence has elapsed.

Some features I may add:

  • Ability to upload automatically to a server
  • Notifications with images or videos sent to email or SMS
  • Ability to check live feed remotely via Internet.
  • Timestamps on the video
  • Delayed start
  • Schedules
  • Better power management
  • Ability to save only audio and no video
  • Motion sensing
