Spy audio devices can be classified according to their specific design. Depending on the surveillance or intelligence gathering objective, there are devices with advanced features that optimize sound capture in different environments. Within this classification, we find sound-activated voice recorders, long-range microphones, devices with audio encryption, and microphones with real-time listening , each adapted to different uses.
At ESPIAMOS® , we offer a wide selection of spy audio devices designed for covert monitoring, personal security, and evidence collection . Each device is optimized to ensure the highest sound quality and discretion.
Spy audio devices are designed with specific functions for different surveillance and security scenarios. Depending on the intended use, we can find models with automatic recording, live streaming, long-range capture, or audio encryption . Below, we present the main functions of these devices and their most relevant features.
These spy recorders are designed to automatically start recording when they detect noise in the environment. They're ideal for optimizing storage and capturing only relevant conversations or events.
These devices are designed to capture sound at greater distances than a conventional microphone. They are used for outdoor surveillance, in auditoriums, or in large spaces .
Encrypted microphones ensure that audio transmission cannot be intercepted, offering maximum security in sensitive environments.
These spy microphones allow remote monitoring of the environment using technologies such as GSM, WiFi or radio frequency .
These devices can detect sound through walls, ceilings, or solid surfaces by detecting vibrations.
At ESPIAMOS® , we offer a selection of voice recorders and spy microphones designed for every security and surveillance need. We also guarantee exclusive benefits for our customers:

What is the difference between a sound-activated voice recorder and a conventional recorder?
Sound-activated spy voice recorders only start recording when they detect noise in the environment, optimizing battery and storage. In contrast, a conventional recorder can record continuously without interruptions.
Can long-range microphones pick up audio clearly?
Yes, long-range microphones are designed to filter out ambient noise and focus on the sound source, allowing conversations to be picked up from several meters away.
How do audio-encrypted microphones work?
These devices use end-to-end encryption to protect audio transmission and prevent it from being intercepted by third parties. They are ideal for secure communications in sensitive environments.
Is it possible to listen in real time with a spy microphone?
Yes, GSM, WiFi, or RF spy microphones allow you to listen to live audio from a mobile device, computer, or dedicated receiver.
Can contact microphones pick up sound through any wall?
It depends on the thickness and material of the wall. Contact microphones work best on solid surfaces like wood, plaster, or metal, transforming vibrations into audible sound.
What is the battery life of a sound-activated voice recorder?
Battery life may vary by model, but some recorders can remain in standby mode for weeks or even months before activating.
Can spy microphones be detected?
Some devices can be detected with frequency detectors if they transmit live signals. However, standalone voice recorders without connectivity are virtually undetectable.
Where are recordings from spy audio devices stored?
Recordings can be saved to internal memory, microSD cards, or cloud servers , depending on the device model and connectivity.
