Second update,

Actually, the location where the video was stored wasn't very far from here, just about seventy to eighty meters away in an outdoor paid parking lot.
A van was parked there, having undergone some simple modifications, and its interior was equipped with electronic transmitters and receivers capable of capturing the video signals from the cameras.
His laptop was merely an intermediary device; although it could display the content captured, it could only show live broadcasts at most.
To review the entire process, he had to come here to retrieve the stored hard drive.
Due to signal transmission limitations, the receivers couldn't be situated too far from the cameras. Plus, the open-air parking lot offered minimal signal interference, naturally making it the optimal location.
As the parking lot was fee-based, as long as one paid enough, there would be no problem leaving a car there for many days, and with someone watching, theft wasn't a concern…
