They Deleted 93% of Their Evidence
A major U.S. city had 14,847 cameras. After 7 days, the video got deleted - not because they wanted to, but because storing 4.7 petabytes per month at cloud rates would bankrupt the department. Detectives learned to solve cases fast or not at all.

The Solution
We put the analysis near the cameras - at local points of presence like substations and network hubs. Each location runs ML models that index what's happening across nearby cameras - person, vehicle, event type, timestamp. Raw video stays on cheap local storage. Only the index and flagged clips go to the cloud. A 4.7PB problem became a 47GB problem.
Local Point-of-Presence Indexing
Each location runs object detection and event classification for nearby cameras. Instead of storing 4.7PB of raw video in the cloud, we store 47GB of metadata and 230GB of flagged clips. That's a 99.4% reduction.
Searchable Everything
Detective needs 'red sedan, Tuesday 2-4pm, near intersection X'? Search returns 47 clips in 3 seconds. Old way: watch 48 hours of footage from 6 cameras.
Local Long-Term Storage
Raw video stays on local NAS at each camera cluster. Cost: $0.003/GB/month vs $0.023 for S3. We went from 7-day retention to 5 years for less money.
The Results
The police commander stopped getting complaints about missing footage. Detectives went from 3 days of video scrubbing to 4 hours of targeted review. The 18 operators now focus on alerts instead of watching feeds. And the budget actually went down.
