Latency from motion detection to push notification?

    Usually between 4 and 60 seconds, depending on how long the motion itself lasts. Its probably too long for an intercom model.

     

    What might work for you would be to get one of our Logitech POP Smart Button systems. You can use that button as an instant notification system, then pull up the Live View from Circle (I believe there is a prebuilt integration for this in the POP app).

    10 to 60 seconds, are you serious? Are you trying to tell me that:

    When motion is detected:

    • You take the whole clip sending it to your datacenter
    • when finished you run your detection software to decide if a push notificationis appropriate
    • if so then send it

    ???

    Hi @Hans-Thomas Mueller?,

     

    When our system detects motion, the video starts streaming to cloud immediately. That stream is evaluated continuously and a notification can be sent even before the motion stop's, depending on the type and classification of the motion that is occurring. Our system does NOT wait until the motion is over to analyze the video, it is evaluated on an ongoing basis.

     

    So, why do we have a few seconds at the start? This is because we need to accumulate enough video so that our Computer Vision system can accurately asses the content. Having enough content is why Circle has a much lower false positive rate in its notifications than other systems. We are trading a little bit of time to allow for evaluating that content. In addition, both Apple and Google have a small delay in propagating the push notification when we send it to them.
