Motion Sensor with Alarm Suggestions

Looking for something that can detect motion and trigger an alarm with the following preferable caveats:

1. Alarm is built into the device. it does not depend on triggering another device wirelessly in case thieves are using a jamming device.

2. Triggers only on human / human like motion. Doesn’t trigger for like flies or small things

3. I can set an away / home mode so it is only active when I’m away. Preferably can be linked to Alexa (or an app) to do this.

4. Can alert me if the alarm has went off
