Stand alone motion detector plus siren ?

I’m a firm believer in motion sensors connected to sirens. Can anyone recommend a device that works like a game camera, (think motion sensor) but has a loud siren instead of a camera. I want to flip a switch and have ~ 10 seconds to close the door on the shed, or the door on my box truck, etc… and have this system armed and ready to scream when disturbed. It also needs the same ~ 10 second delay so I can disable it upon my opening the space back up. Battery powered.

Thanks !
