At least 50 U.S. law enforcement agencies are now equipped with a radar device that allows them to detect human movement through the walls of houses.

The device known as Range-R operates as a highly sensitive Doppler motion detector, according to its official website.

It can detect human movement from a distance of up to 50 feet, the USA Today reports.

The device beams radar waves through a wall and calculates the distance of the target by analyzing the reflected waves, according to manufacturer L-3 Communications.

The device has a 160-degree conical field of view and can detect movements as slight as human breathing.

It works through brick as well as concrete, but cannot penetrate metal, according to the Inquisitr.

Use of the technology raises both legal and privacy issues and a 2001 U.S. Supreme Court ruling barred authorities from using high-tech sensors to scan inside someone’s home without first obtaining a search warrant.
