Notifications and 2 way audio

New to this system, but my question is when a notification comes through which is a 2 or 3 second delay from detection of movement, is there a fast way of communicating on the 2 way audio, before the person walks away, with out having to open the app?

I installed a sensor to give earlier indication. My biggest issue now is the 2 second delay in audio coming out of the camera doorbell. I find the audio delay in a security product at this price range unforgiveable.
