Moving and stationary audio observation with technical aids.The target person with whom you have visual contact, but whose conversation you want to follow is in open terrain. However, you must keep your distance to avoid being noticed, then you can use the directional microphone to still conduct an audio observation and participate in the events from a greater distance to collect usable evidence. This tool is useful for stationary observations, where you observe the suspect from neighboring properties or forests. Eavesdropping on conversations through walls and barriers is physically completely impossible with a directional microphone, even if fools claim otherwise. |
FEATURES:
If conversations in open terrain need to be observed over greater distances, the human ear is usually not sufficient to perceive usable information. Under these conditions, this task can only be solved using electronic aids such as our outstanding directional microphone. By precisely aligning our directional microphone, it is possible to focus on specific sound sources. The acoustic signals entering through the sound entry openings of the directional microphone, which can be adjusted with switchable directional characteristics (cardioid/supercardioid), are acoustically amplified according to their frequency affiliation and fed to the high-performance audio amplifier, with connection options for headphones and digital audio, optimized there, and can then be listened to live via headphones or recorded digitally on a cell phone, tablet, or PC. In the interaction of the directional microphone and operational amplifier, even faint noises can be captured over greater distances, e.g., for wildlife observation and surveillance tasks when monitoring conversations in open terrain. Since the device is naturally also suitable for "eavesdropping," we point out that personal rights must be respected. The microphone complies with all relevant EU directives and is accordingly marked.
For the sake of good order and to prevent you from making a wrong purchase decision, we feel compelled to point out that the majority of directional microphones advertised by so-called "detective shops" correspond at best to a child's toy for the sandbox. Completely unusable for any serious application. Most of the time, it is always the same model in the 20 € to "believe it or not" 100 € segment. What you hear with it is nothing!
