@Solla-topee  Why is this not a standard feature across all the models? All the cams have the siren capability and detection we just need a way to manually trigger it. 

C500 models and others already has this functionality. I was trying to setup something similar as OP for all of my devices and I was able to do it for C500s. 

When I tried to do the same for C320ws there was no option itself. Only privacy filter option is available. This just feels like a let down. Its a perfectly capable device. 

Please take this feature request up. There are lots of people who would like this functionality as I can see from the responses. And this thread itself was created 3 years ago.

  @hpp8140 +1 - Manual alarm trigger please.

  @Solla-topee Sorry for replying to the old thread. The ability to activate the siren manually is the only reason I keep buying WYZE cameras. If Tapo would offer this feature I would switch to Tapo (right now I have a couple of them). The scenarios when we use them? Imagine a small business, eg, a small gas station. Talking to customers not always helps, but activatin the siren stops them instantly from trying illegal things, like smoking near the fuel dispenser, littering, trying to urinate (when it is dark outside), trying to walk into (access) restricted areas, and the list goes on. It is really a much needed and useful feature, it basically instantly informs a person that they are being watched, and this instantly changes their behavior. Automated messages like "Hi, you are currently beign recorded" ofered by Wyze do not have the same effect as a siren.
