Police Radars Inside Homes - Be careful what you do inside your homes because the government could be watching your every move. This isn't quite surprising given there had already been reports that the government has been listening to phone calls to filter out calls that could be related to terrorist activities. Yet, is the latest police radar a complete violation of privacy?

The government appears not to care about privacy at all. Their latest invention used by officials now allows them to see inside homes. The police radars inside homes have been equipped to more than 50 US law enforcement agencies.

However, USA Today claims that the police radars inside homes' equipment has been deployed two years ago. It has been used by agencies such as the US Marshals Service and by the FBI. No such notice of the use of their equipment was given to the court or disclosed to the public.

"The idea that the government can send signals through the wall of your house to figure out what's inside is problematic," says American Civil Liberties Union's principal technologist, Christopher Soghoian, in a report by USA Today, adding, "Technologies that allow the police to look inside of a home are among the intrusive tools that police have."

Police radars inside homes' technology raises privacy and legal issues. The Supreme Court states that the officers using such device need a search warrant before using the radar. How exactly do the radars even work?

The police radars inside homes' uses motion detectors, which are finely tuned. It uses radio waves that zeroes in on slight movements, even something as light as breathing, from a distance of 50 feet or more. The device can also quickly detect if someone is inside a house, mobile or not.

While the police radars inside homes' technology is still privy to privacy, federal officials claim they use the radar for storming into buildings where a hostage is taking place.
