Strapped for cash and facing a sharp rise in homicides, city leaders here are expanding police surveillance powers to allow residents and business owners to send live feeds from many types of security cameras — including popular doorbell cameras — directly to the city's real-time command center.

The new use of this livestreaming technology by police, which is undergoing a final legal review in Jackson, is drawing interest from other small cities that don't have the resources to build their own surveillance systems. But some have opted out, citing concerns about privacy violations. Civil liberties advocates say those concerns are valid, warning that the technology could lead to increased police scrutiny of people's everyday activities and more arrests for low-level offenses.

"What you see behind us is an opportunity, an opportunity to better observe and fill in the gaps," Jackson Mayor Chokwe Lumumba said last month at the ribbon-cutting for the city's new command center.
