Hey ya'll has anyone of you seen the video by seytonic on how hackers are unlocking doors using CCTV? I understood the concept behind it, but is anyone willing to explain that shit to me in detail?

Watching that video was like trying to unlock the mysteries of the universe with a keycard! 🚪🔓 I need a hacker-to-English translator, pronto! 😂 #CCTVHacks

Very simple.

When the code is read the power levels inside the device fluctuate while calculating whether the code is correct or not.
By monitoring the power fluctuations you are able to determine what the code was due to the power consumption.

After that it's about making sure you can detect all the individual small flashes. A normal cameras shutter speed is too slow to capture it so what they did was took individual frames from each layer to maximize the amount of frames they could detect.
