All solutions responsible for the quality of recorded audio are enclosed in an aesthetic and elegant body, ensuring complete discretion. At first and second glance, the device looks like a pendrive or a portable hard drive, which further enhances its invisibility.
Moreover, the voice recorder will in no way signal its operation or activity that could provoke suspicion from strangers – during recording, the LED is off, and the device makes no sound.
Voice Recorder Memory
The voice recorder has built-in 16GB memory, allowing you to store recordings in various formats and qualities. You can set the bitrate from 1 to 5, which affects sound quality and the number of hours of recordings that can be stored:
- 256kbps - up to 144 hours of recordings (MP3/WAV)
- 512kbps - up to 72 hours of recordings (MP3/WAV)
- 768kbps - up to 48 hours of recordings (MP3/WAV)
- 1024kbps - up to 36 hours of recordings (MP3/WAV)
- 1536kbps - up to 24 hours of recordings (MP3/WAV)

Operating Modes
- 1 - Continuous
- 2 - Voice-Activated
The first mode is responsible for continuous recording, meaning from the moment the device is switched on in this mode, the voice recorder will record for up to 50 hours.
The second mode, activated by voice, does not record constantly but only registers content when it is spoken. Thanks to this capability - sound detection - you can be sure that the files saved on the device will record speech in its entirety, and thus will not be devoid of meaning or context.
This also extends the device's operating time, as it will consume less power and memory. In this mode, the voice recorder will operate for even several hundred hours.
Additional Operating Modes
In addition to the basic modes (continuous recording, voice-activated recording), the voice recorder also features:
1. Scheduled Recording Mode – possibility to set the start and end time of a recording.
2. Cyclical Recording Mode – automatic splitting of recordings into time segments.
This solution makes the voice recorder very versatile and suitable for both long-term placement and recording specific meetings. Ideal for teachers, students, journalists, lawyers, businessmen, older people... it will work anywhere and in any situation.

VOR System
One of the distinguishing features of the voice recorder is the VOR (Voice Operated Recording) system. This technology automatically starts recording upon sound detection and stops when the sound fades. This solution allows for saving space in the device's memory and increases ease of use.
Noise Reduction
The voice recorder has a noise reduction function, which blocks ambient sounds, ensuring clear recordings and the ability to adjust playback speed.
Excellent Quality
Thanks to a highly sensitive microphone located on top of the device, the voice recorder captures even the quietest sounds. Microphones positioned in various locations allow for 360° sound recording, up to 100 meters away.
Recording Segmentation
The voice recorder is equipped with a recording segmentation function, which automatically divides the file into smaller fragments after a specified time. The user can independently set the segment length from 10 to 240 minutes per segment, which facilitates later processing and management of recordings.

Intelligent recording management
The spy voice recorder offers advanced functions that enhance user convenience. The ability to adjust recording sensitivity on a scale of 1 to 7 allows for tailoring recording volume to individual needs – the higher the number, the louder the recording.
Additionally, the voice recorder is equipped with a built-in file management system that automatically saves each recording according to the registration date.
Other files can also be stored on the device's disk, making it a versatile tool for everyday use.

Exceptional Functionality
The voice recorder stands out with its exceptional functionality thanks to its built-in headphone jack (headphones included in the set). Now you can comfortably listen to your recordings in a library, cafe, or while traveling, without disturbing others and enjoying privacy. The voice recorder has the ability to fast forward and rewind recordings, which greatly facilitates managing audio files.
Additionally, the voice recorder serves not only as a reliable recording device but also as a high-quality music player. The built-in equalizer ensures that every listened recording or favorite song sounds excellent.
Recordings are incredibly clear and distinct, providing comfort while listening. The ability to play recordings directly from the device makes it even more versatile.

OTG Function
Thanks to the OTG (On-The-Go) function, the spy voice recorder can be connected directly to a phone or tablet. This allows for quick and convenient transfer of audio files to a mobile device, eliminating the need for a computer.
Example: Imagine you've just recorded an important conversation during a business meeting. Instead of waiting until you return to the office and connect the voice recorder to your computer, you can immediately connect it to your phone and send the recording to your colleagues. This is a quick and convenient solution that saves time and allows for immediate action.
Automatic Save
The voice recorder has been designed with the complete security of your recordings in mind, even in critical situations. Thanks to its advanced automatic save function, the device intelligently detects a low battery level and immediately saves all files before it discharges. You can be sure that none of your valuable recordings will be lost, even when the battery is running low.

Practical Lanyard
An additional advantage is the possibility of hanging the voice recorder on a lanyard, thanks to a special slot located on the side of the device. This solution allows for even more discreet placement of the voice recorder, while ensuring comfortable use.
