Motorola Inc. has set its sights on emerging technology that could allow first responders and Special Forces to see through building walls. The Schaumburg, Ill.-based company joined other investors in a $5 million funding round for Camero Inc., an Israeli firm founded by technology and intelligence veterans.

Camero is developing a portable imaging radar that uses ultra-wideband technology to create a 3-D picture of objects that are concealed by walls or other barriers. An official with Motorola Ventures, the company's venture capital arm, said the technology could have a major impact on public safety.
