Wow I never thought that this product could exist, excellent hunting @ francisco2351, I will leave my personal opinion about this product.

Pros:

• It is perfect for those people who like to maintain their privacy, I also think it is essential for smart homes.
• It is small compact and has a protection radius of up to 300 meters around.
• You can link to your mobile application available for Android and iOS, where it sends you alerts of any unusual activity.

Cons:

• None for this hunt.
