Happy to see the floodlight cam arrived so quickly and that you are satisfied with this addition to your ‘Ring of security’. The automatic triggering of the siren sounds like it could possibly be obtained through IFTTT or a recipe type software. I will most definitely share your interest with the team here about adding recipes and rules into the app. We always love to hear feedback regarding possible new features for the app so please continue to share as you enjoy your new Floodlight Cam.
