I will try to post a picture of my siren. It is basically a very small siren in a piece of PVC tube. It about 1/4" wide by 4" long tube. It has a servo plug on the end. It monitors a valid signal from the receiver. If I signal pulse is detected, the siren goes off. Once the pulse width is valid, it shuts off the siren. Very simple and these are commercially available.

The smaller ones arent loud at all, more like a buzzing niose, but this one will blow your ears out. Put the 1/3 Camera in there for size comparrison
