After spending some time looking for a decent guide, I came up empty-handed. My best suggestion would be to watch this YouTube guide, as he goes over using the app to set up the camera which is where the active deterrence settings (siren, spotlight) are configured. Most of that begins at the 3:40 mark. EVERYTHING is done through the app, there's no other way, so it appears you must install the app on your smartphone, set up a cloud account, scan a QR code and take it from there.
If the link video below doesn't help, there are more and perhaps better videos in that same section that will help you. Good luck!
