City officials revealed the six finalists that could snag the camera contract. Those companies are American Traffic Solutions, GATSO USA, Optotraffic, Redflex Traffic Systems, SENSYS America and Conduent Incorporated.
All six of the possible vendors are currently dealing with legal issues across the nation.
The release came after tense moments at Baltimore City Hall Wednesday. Reporters and the mayor went back and forth about releasing the candidates' names.
Reporters were insistent that the company names be released based on their desire for transparency. The red light and speed cameras were deactivated around three years ago because of errors with cameras issues erroneous tickets.
Baltimore Mayor Catherine Pugh said she did not know the names of the companies, but that there would be a testing period before they are official activated.
"Let me just be real clear. First of all, the information will be released and in the first 30 days of the cameras being on the streets it will be a test. Nobody will be getting tickets. It will be a test. We will make sure. If I knew I would shout it out to you."
The city is reactivating the cameras to increase safety and to raise an expected $20 million each year.
Pugh promised the new system would be smaller and better monitored.
