Yeah mine has a built in sirenSome of the Reolink cameras have built in sirens. How good they are, I don’t know I’m afraid
Can even set it off remotely
It's decently loud yes
But a dedicated alarm sirens probably louder
Since can fit a bigger speaker in it
And can have flashing lights etc
As always it all depends how much you want
To spend
Reolink stuff is decent for the cost definitely
But not really top of the range stuff
And as simon42 said
Physical security is even more important than cameras
