Incompatible refresh rate. For your camera, that would be analogous to frame rate. I'm not a video or computer tech, I'm in audio engineering, but this might be helpful:Does anyone know why the displays on Viva buses and stations don't show well on camera and video? This isn't the case for TTC buses.

LED signs are driven by 'registers' which are often pulse-width modulated, and synched to a driver that has its own operating frequency. What you can't see but what that sign is doing is flashing on and off, perhaps with a multiple rate simultaneously, far faster than your eye can see, but which 'falls between the cracks' of the lattice your camera works with.
You may have an option in your software or hardware to do a work-around on that. It might be known as a 'strobe effect' still, as this was referred to decades ago in video work. (Flourescent lights and TV cameras were a nightmare to get to work together)(24 frames per/sec and 30 cyc per sec are not easily synched).
