for what it's worth, the DeFlock maps also include Axon/Motorola cams. they pick up my city's custom implementation too so the anti-surveillance movement is really benefiting from this Flock-focused hate
EFF's Atlas of Surveillance also does a really great job keeping track of contracts with these companies: https://www.atlasofsurveillance.org/
if you feel up for it, filing some ORRs according to your local statute for these contracts and sending them to the EFF is a great way of getting involved on a small scale. MuckRock has an entire tool for it that someone on HN pointed me to a few days ago (https://www.muckrock.com/foi/create/) and I'm going to spend an evening or so sending out some requests :)
