The Vision Shock Sensor you linked to might not look as good as some of the others, but the sensitivity is adjustable and it eliminates the need to have a vibration sensor and a contact sensor.
You can attach a small cheap dumb sensor like this to the internal contacts and use this DTH to have it work as a motion sensor and contact sensor.
Disclaimer: If the window is closed and opens, you’ll know that it opened, but it doesn’t automatically report closed again once it’s shut.
