I am looking for motion sensors that sit on my window cill that points out of window and can detect a person outside but only up to a few meters. I would like a buzzer that goes off but not a loud siren. I dont have Wifi for security risks as everything is multiple VLANs via ethernet cables. Can you please recommend what would be suitable to achieve this, Thank you

 

The sensor will not work through glass, as the glass blocks the infrared needed for it to detect movement. It would need to be positioned with a clear, unobstructed view to operate correctly.

If you’d like help finding an alternative that will suit your setup, I’m happy to assist.

Yes please, I would like an alternative that has a built in buzzer or chime(not a loud siren). Also it must not need to connect to wifi as looking for a basic standalone device. Thank you.

A pro IP camera could do this but wifi based camera are not usually pro level. This would enable an app on a phone with smart push notifications.
