This site is pretty much devoted to avoiding detection from governments. But as technology becomes more affordable it can be used by corporations and even community groups.
Automated license plate readers (ALPRs) are all the rage:
At least seven homeowner associations (HOAs) in San Diego County, 100 neighborhoods in Georgia, 10 in the Denver area, and dozens throughout North Carolina, South Carolina, Alabama, Tennessee, Texas, and elsewhere have installed A.I.-infused ALPRs manufactured by Flock and a handful of other companies such as Vigilant Solutions and Obsidian Integration. Flock provides a calculator that recommends the number of cameras that neighborhoods should install: For 50 homes with two entrances, it recommends between two to four cameras; for 100 homes with five entrances, it recommends between five and 10. Each camera costs $2,000 per year.
