{"id":223,"count":4,"description":"Just as a doctor listens to a patient\u2019s chest, a wall can also be listened to. This allows sounds from an adjoining room to be heard clearly and distinctly. To do this, a probe is attached to the relevant wall. The wall can then be monitored using the device. Conversations and similar sounds are transmitted via the probe to the headphones. The probe picks up sound waves from the adjacent room, regardless of whether the walls are made of steel, wood or concrete. You can listen in on the conversation without having to set up a recording device beforehand. Wall stethoscopes are available in various sizes and dimensions. They are powered by rechargeable batteries built into the device.        \nMonitoring via our audio devices\nSometimes you simply need to know what\u2019s going on in the room next door. If you have a specific suspicion, eavesdropping can confirm or dispel it. Eavesdropping is also often used to prevent crime. However, you don\u2019t always have access to the relevant rooms and so cannot place a recording device there. In such cases, other methods must be employed. The wall stethoscopes mentioned are easy to use and work with great precision. The probes they contain are particularly sensitive and can pick up even the slightest sound. Not a single sound will escape them. In this way, conversations in the room in question can be clearly overheard, just as if you were there yourself. With the wall stethoscope from our range, you will never miss anything important again. Depending on the size of the wall stethoscope, it can penetrate various building materials; this little eavesdropper, with its impressive hearing ability, easily picks up sound waves even through thick steel and concrete walls.
