Prisons in Maryland and other states have created a niche market for clear-case electronics, including televisions, to ensure that prisoners cannot hide contraband in the devices in their cells, says the Baltimore Sun. TVs, music players and video game systems all must be see-through under the regulations of most Maryland prisons.
Walkenhorst’s, a prison supply company in California, manufactures and sells about 6,000 see-through sets a year under the brand name Hiteker. The sets sell for about $200 each and can be ordered by third parties and shipped to inmates. “It’s a small market,” said owner Stewart Walkenhorst. He said that because it is expensive to set up the manufacturing tools for clear encasements, “you don’t have the big majors chasing it.”
