280 Pixelated Image and Gecko Power

Zhao Yu's long term detector was on. With the detector, he could tell the location of nearby cameras and electronic devices that video or voice recording functions. What was interesting was that the detector could even sense if someone was using their cellphone. If anyone turned on video or voice recording, the detector would show a red warning sign and pinpoint the exact location of it.

Zhao Yu felt the warning came from inside of the room. He looked closely at the image in his mind. In the room, there were a number of hidden cameras, and also a high tech infrared alarm device.

"Wow…" Zhao Yu cringed and thought, "Why would a gym need a high tech infrared alarm device? Maybe this room was the gym's finance department? Is there a safety deposit box?"
