The Hartford Police Department has begun rolling out body cams to its officers to use on a daily basis. Using a combination of state grant money and funding from the city, the department purchased 325 cameras. The cameras, supporting equipment, and some cloud storage space came from Axon, a company that started out making tasers in the 1990s. Since the launch of its pilot program in February, officers have recorded more than 12,000 videos with the body-worn cameras.
