Chattanooga police adding eight more public safety cameras in November
More public safety cameras are coming to Chattanooga to help police solve violent crimes.
Chattanooga Police Sgt. William Atwell, who oversees the Real Time Intelligence Center, said the cameras working.
Next month, police will add eight more cameras to the 29 already installed in Chattanooga.
The police department uses a combination of data, police and citizen input when deciding where the cameras will go.
First, police draw a 1/4 mile radius around the existing cameras and analyze violent crime over one year. Then they compare that data to city-wide violent crime over a three-year period.
"That gives us location based on data. Then we take that information and give it to the officers that work the areas and ask for their input," Atwell said.
Police also share the data during community meetings for citizen input.
All of the data and suggestions are then ranked and the police chief makes the final decision.
"We realized that one location the officer gave us was really high in violent crime but it didn't show up in our initial data analysis because it was already within the 1/4 mile range of a camera. So officer and citizen input is very important," Atwell added.
Each camera costs $13,000. The camera is built to withstand weather and comes with it's own heating and cooling system.
The cameras are installed on EPB poles that supply power and fiber. Atwell said it costs $120 a month to run each camera.
They feed video to the Real Time Intelligence Center where the video is stored for 30 days unless it is saved permanently.
"After people understand what we're actually doing and how we're using it to solve crime, they've been very receptive to it," Atwell said.
The new cameras will be added in November.
