In investigation and audio monitoring field, there are different types of wall microphones and stethoscopes, equipped with different features to be used in specific application areas:
- Standard contact microphones
This device has a very good value for money. It’s suitable for beginners in investigation. It allows you to listen and detect clear and stable sounds. It’s equipped with outputs for voice recorders and earphones and has a good sensitivity. They are designed to detect all noises, including the faintest, through thin walls. Please note that the contact microphone and the amplifier can be assembled in one device.
- Professional microphones or wall stethoscopes
State-of-the-art wall microphones. The stereo stethoscope allows you to secretly listen through solid structures like walls, wide roofs, windows, doors and floors. This device is very efficient thanks to two high sensitivity sensors detecting faint vibrations generated by sound waves. The stereo amplifier amplifies the faint sound waves and that can be listened with earphones or live for recording. This is an important advantage. By using this device, the smallest sound vibrations detected by sensors are amplified (high amplification of bass sounds), so that even faint sounds can be heard. The automatic selection of the threshold frequencies of amplification levels and microphones, ensures the best fine tuning basing on the operating conditions.
- Wall microphones with pin sensor
This microphone is equipped with a high sensitivity pin sensor or needle sensor that is to be inserted inside the wall and ensures very high performances.
- Wireless transmitter contact stethoscope
It’s a special quartz stabilized stethoscope contact bug for audio surveillance through walls, glasses, windows, etc. The contact stethoscope bug is integrated inside a metal body and equipped with a battery-powered external sliding flexible antenna for quick replacement. Listening is by RF transmission (WFM).
