They hadn't discovered anything strange in those cameras, but they had indeed found a strange frequency that was captured and recorded by the neural connection of the mechas.
And after those in the research center and tech center worked on it, they finally pinpointed that, according to the frequencies received by the different mechas and comparing their distance.
They managed to pinpoint that the frequency indeed came from the group of high-level zergs that Lewis had continued chasing.
They found the source of the strange frequency, but even after checking all the cameras on the battlefield and all the cameras from the mechas, they still couldn't find what Lewis had discovered on those zergs.
Because they really couldn't find anything on the cameras no matter how they slowed down the videos, those technicians and researchers focused on studying the strange frequency that the mechas managed to intercept.
