There is of course a security concern, but the primary concern is protecting the lucrative monopoly that the prison system has on phone usage.

hm, Why do you worry about privacy on a radio--that is, a cell phone? The stuff is transmitted in the clear for the most part. It doesn't take much to receive cellular transmissions, many software defined radios will do this for you. If you need privacy for a conversation (and my feeling is that if you want it, you should have it) then you need to take steps to guarantee your own encryption.

Will this instrument also listen to cell phones not used by jail inmates? Is use of this instrument privacy concern? How if common citizen uses this to monitor some other fellow citizen or police?

I have used this product and it has its flaws, yes it does work but its acuracy is not all that and my work 800 Mhz radio as well as the Microwave sets it off.

Since the U.S. has by far the largest per capita prison population of any nation, there should be a huge market for this device.

Illegal cell phone detector needs a receiver of all the bands of operating frequencies, a decoder,and data storage system. The software is to be so advanced that it can decode any calls received and transmitted.Quite a specific application.
