Can it sense movement thru a window?

The unit senses motion that are in it's direct line of sight. If there's obstacles in the way, it won't detect motion

Does it has rechargeable battery inside the unit or have to be connected to power to operate?

Removable rechargeable battery comes with the unit. Just plug it into the charger and off you go. Charge lasts very long time. The unit can be really loud as long as the sounds on the included 128 Mb micro sd card are recorded at maximum loudness.

Will this take a microSD card bigger than 128mb?

Yes, it will. While the device supports up to 32 GB cards, we don't recommend using a card larger than 8 GB, as may cause some delay between motion detection and audio playback

Where is this product manufactured - USA or other?

Like just about everything except cars and fresh produce... it's made in China.
