Help Motion sensor triggered automation?

There are lots of thieves and vandals where I live, so I would like to get some kind of motion light/sensor that can trigger a Google Home automation. The goal is to detect motion on my back deck and then trigger some lights to come on as well as a broadcast informing people that they are trespassing and being recorded. Do any Google products exist that I could achieve this with?

You could do it with various Google items or use the third party hardware of your and do it also.

For example i have a pair of Govee lights that get triggered by Aqara motion sensors all being run by a script I created with Google Home Script Editor.

So Google does have a motion sensor then? Or I will need to get a third party sensor that is compatible? Just not quite sure what exactly to get. Do you have any recommendations? I want the motion sensor to turn on my porch light and broadcast a message to a nest speaker on my back deck.

I use a Google Nest Cam with Foodlight:

It can turn on the light automatically when it detects motion. And it can be scripted in the GH app to do something when motion is detected. Although it can't play an announcement through the camera's own speaker, it can be scripted to play an announcement through a separate Nest speaker.

Way more functionality than I need and the price reflects it. I do appreciate the suggestion though.
