Police surveillance of downtown Houston will expand with the addition of 180 new cameras.
The installation of the cameras means police will have nearly 1,000 surveillance feeds available to them. Most cameras are pointed on public areas around downtown, stadiums and the theater district.
Police Chief Charles McClelland says Houston has more critical infrastructure than New York City and must rely on video to provide necessary police coverage.
The city has spent more than $18 million in federal money to build its camera system and has another $5 million in reserve.
Houston also has expanded its video network through private sharing agreements, such as by accessing networks along rail lines.
Officials say data is not kept to determine if the cameras are driving down crime.
