Video detection already behaves in this fashion. For example, you trigger video detection then within the timeframe of “trig duration” you cannot retrigger video detection alert.
Currently, audio detection detects any audio above threshold even if it was half a second after the last audio trigger. The “trig duration” parameter does not affect this.
Also, it would be nice if a video alert could make an audio alert get placed on cooldown too so that if a video alert happens with some audio trigger soon after, then it won’t send another alert.
