SH-055UEx professional_handheld LCD mobile phone detector Detects reactions to mobile phone inside and outside prison cell

This video primarily illustrates the SH-055UEx's reactions to two different ways of using mobile phones inside and outside prison cells.

We couldn't film inside an actual prison, so we'll provide explanations using the following two scenarios.

1. The phone and the detector are in the same room, detecting the

reactions when the phone makes a call and browses the internet.

2. The detector is outside the room, detecting the reactions when the

phone makes a call and browses the internet.
