Automatic wake-up using front camera

If you device is equipped with a front camera, you can use it to automatically wake-up the device when a move is detected.

This feature is only available in dashboard view.

Several options for this feature are available in the Dashboard view preferences:

  • Wake-up with camera: to activate or not the feature
  • Camera wake-up threshold: the "importance of the move" that has to be detected to wak-up the device (represented in number of pixels that should change)
  • Camera wake-up debug mode: to help you defining proper value for above property. Can also help to debug if the wake-up does not work

WARNING: this feature is highly dependent on the device. As such, we can not guarantee it will work with all tablets.

Moreover, the number of Android tablets available on the market being huge, we can not provide an exhaustive list of compatible devices.
Still, here are some working and not-working devices that our users have communicated:

    The alternative method with "motion detector" works fine on the Hudl2, though :-)

    FWIW Works fine with a Lenovo E7 seven inch tablet. The important thing to note is that you may need to go into permissions for the app and grant it access to the camera - before I did that I could jump around in front of the tablet waving my hands like a windmill with no response. The app on installation didn't ask for permission to access to the camera. I wonder if those having issues have a version of android that locks down the app - my Lenovo is running Oreo (specifically Android 8.1.0). Perhaps those who are fine without having to muck around with permissions may be running Android 5.0 or older?

    TLDR - if the motion detection isn't working for you, go into settings on your device and make sure that the imperihome app has access to the camera.

    It is working fine with my Google Nexus 7 2013 (16GB) with default sensibility.
    The same problem as Mikaël: when using another application and then coming back to Imperihome automatic wake-up doesn't work anymore.
    I have to close Imperihome and start it again (but I don't have to reboot the tablet).

    It works because I use automatic start of Imperihome. If i leave Imperihome and start it again then it doesn't work.
    It work only if I don't leave Imperihome. If I leave Imperihome to use another application and then start again Imperihome then it doesn't work anymore.
    I have to restart and wait for automatic start of Imperihome and then it works again.
