What each version added

The map grows from one city to the whole county, and learns to explain itself.

• All of Tarrant County and Fort Worth. Every camera reported on DeFlock.org inside the county or the city — 1,193 at launch, up from 438 — with a one-click Fort Worth only view. Every count in the filter follows your choice, and the map remembers it.
• Photographs accepted from the same area. Anything you can submit is something the map can show. (The old check was a box drawn round the county; it turned away four cameras in north Fort Worth.)
• A map key. Every symbol, what it means, and what the map does not claim — drawn by the same code that draws the map, so it cannot fall out of date.
• Cameras that come down stay on the record. A dashed ring while nobody has confirmed why a camera left the feed; a green struck circle once someone has checked the pole. The only green on the map, and never set automatically.
• Places a camera can see, county-wide. Churches, schools, clinics, playgrounds and more: 738 within 1,000 feet of a camera, 54 within 250.
• One vocabulary. Photographed sites and imported reports share the same marks; the filter shows the same symbols as the map.
• The company by its name. Flock Group Inc., not the trade name. The one place the map quotes an OpenStreetMap record says so, and the key explains why.
• Better on a phone. The map is never hidden behind the filter.
