Waltham
The Waltham Police Department has had Flock ALPR (Automated License Plate Reader) cameras installed throughout the city since at least September 2025. As of November 1, 2025, there is no record on the City website for anything regarding Flock. There is no record of community engagement, or any announcement of either the contract or the deployment of the surveillance technology.
The map below shows crowdsourced locations of known ALPRs.
A Police Records Request received November 3, 2025 includes among the following:
- Flock contract
- Master Services Agreement (MSA)
- Memorandum of Understanding (MOU)
- Purchase Order
- Sole Source letter
Next Steps
This latest release has a lot of information.
Ways you can help:
- Read thoroughly and identify any concerning items
- Understand full capabilities of this technology. There are lots of rumors online, but the contract should spell out exactly what features these cameras have
- Break down the procurement process – was it signed too quickly per city procuremenet rules, was the sole source process followed to every letter of the law?
- Turn the table of departments with which Waltham PD is sharing their Flock footage into usable text
- Identify missing cameras on DeFlock.me map and add to OpenStreetMaps
