Lincoln College and the Lincoln Heritage Museum in Lincoln, Illinois moved off an older exacqVision system. They kept every working camera, cable and encoder. Lookout runs on servers they already owned, with no graphics cards.
Lincoln College in Lincoln, Illinois has closed as an institution. The campus has not gone away. The arena, the fitness center, the residence halls and the grounds are still being maintained, and they still need watching.
The Lincoln Heritage Museum is on the same campus. Its cameras protect the collections and exhibits in the museum galleries.
Both sites recorded on exacqVision. Analog cameras were wired to video encoders. A growing set of IP cameras from several vendors had been added over the years. exacqVision servers sat in the middle.
Lookout keeps all of that and replaces only the middle. It watches every camera instead of just recording it, and it tells someone when a person or a vehicle shows up.
Lookout records the stream the camera already sends. It does not decode it and encode it again. At the college, recording all 71 cameras costs about 0.6 of one vCPU.
That leaves the processor for the work that matters: looking at the pictures. At the museum, decoding its cameras for motion takes about a third of one core. AI then checks the moments motion finds, on the cameras chosen for it.
This is why a server processor from 2014 can watch 71 cameras with no graphics card.
