Frequently Asked Questions (FAQs)

What is the best option between a voice recorder and a spy microphone?
It depends on the user's needs. If you're looking to store audio offline , a spy voice recorder is the best option. However, if you need to listen in real time , a GSM, WiFi, or radio frequency spy microphone is more advisable.

How do GSM spy microphones work?
GSM microphones contain a SIM card that allows you to make a call to the device and listen to what's happening around you in real time, without having to be near the location.

What is the difference between a WiFi spy microphone and a GSM microphone?
The WiFi spy microphone transmits live audio over the internet and can be monitored from a mobile app. The GSM microphone , on the other hand, requires a SIM card and allows you to listen in on calls to the device from anywhere with mobile coverage.

Can radio frequency microphones be detected?
Yes, frequency detectors can identify the transmission of a radio frequency microphone , so in sensitive environments it is recommended to combine it with signal encryption devices or change transmission frequencies.

How long does the battery of a spy audio device last?
It depends on the model. Some spy voice recorders can record for 20 to 50 hours , while battery-powered microphones can operate for 6 to 10 hours of continuous transmission . Models with sound-activated standby mode can last for weeks or months .

Is it possible to use a spy microphone without an internet or mobile connection?
Yes, radio frequency microphones do not require an internet connection or mobile networks, as they transmit audio via UHF or VHF signals to a dedicated receiver.

Do Bluetooth spy microphones have good range?
No, Bluetooth spy microphones typically have a limited range of 10 to 15 meters , so they are recommended for recording in small spaces or in private meetings.

Where are audio recordings stored?
Recordings can be saved to internal memory, microSD cards, or cloud servers , depending on the device model and connectivity.
