Flock & ALPR cameras in Maryland
Public map data records 1,010 ALPR cameras inside Maryland's borders as of 3 September 2026, run by 80 different operators. The densest cluster is Rockville, at 908 mapped cameras. See every camera, which way it faces and its approximate capture zone — free, no account.
The 1,010 cameras mapped in Maryland belong to 80 operators, with Anne Arundel County Sheriff's Office at the top on 176. That makes the state widely spread by ALPR standards. Because these are counted inside the border rather than by metro box, the number is directly comparable with other states on this site. 224 of the 1,010 cameras carry no operator at all, so the operator shares above are shares of the attributed cameras.

Read the operator column two ways. By size, Anne Arundel County Sheriff's Office dominates with 176 cameras (17% of the state). By count, the other 79 operators run the remaining 83% between them, and 5 of the top eight are county sheriffs rather than city forces.
Operator attribution comes from OpenStreetMap tagging where recorded and otherwise from the jurisdiction a camera sits in — a strong signal, not a confirmed record. 672 of the 1,010 cameras here carry an inferred operator.

Maryland ALPR questions
How many Flock cameras are there in Maryland?
1,010 mapped cameras inside the state line as of 3 September 2026. That is a true in-state count, not a sum of overlapping city areas — and still a floor, because unmapped cameras don't appear.
Which cities in Maryland have Flock cameras?
The largest clusters are around Rockville (908), Silver Spring (898), Columbia (719), Baltimore (662), Annapolis (438), Frederick (138). Smaller MD towns appear on the live map too — these are simply the biggest metro areas.
Who operates ALPR cameras in Maryland?
The lead operator is Anne Arundel County Sheriff's Office at 176 cameras, but it holds only 17% of the state; the rest is split among 79 other agencies and businesses.
Are all the plate readers in Maryland made by Flock?
No. Flock Safety is tagged on 715 of 866 vendor-recorded cameras (83%); Leonardo accounts for 39, and 118 cameras have no vendor recorded at all. 'Flock camera' is the common name, but the map covers every ALPR it can find.
Can I avoid Flock cameras when driving in Maryland?
Yes, within limits. BanditKin routes around cameras whose facing direction is known — 890 of Maryland's 1,010 — with a slider for how hard to try, and it tells you honestly when no camera-free route exists. It is off by default and never sends your identity or location.
