Pros and cons :
- 5V USB adapter function works.
- Any SIM card can be used.
- Voice alarm function.
- High quality from the EU.
- Due to the adapter design, the applications of the listening device are limited.
This USB adapter features a hidden GSM transmitter that allows you to listen in live from anywhere in the world. The listening functionality is fully integrated into a working 5V/2A USB charger, making the device unobtrusive in a normal home environment. Thanks to the built-in high-quality microphone, this solution is ideal for discreetly monitoring sounds in a room or office.
User-friendly installation without any recognizable signals
The housing of this transmitter has no visible microphone holes or LEDs that could reveal its operation. The SIM card is inserted securely via a hidden compartment under the hood, which can only be opened with the included special tool. Once connected to a power outlet, simply call the SIM card number to listen live. No Wi-Fi, app, or technical installation is required.
Extra security with administrator access and alarm function
To prevent misuse, the system only accepts incoming calls from a pre-defined administrator number. Other calls are automatically rejected. The device also features optional sound detection and vibration alerts. When activated, the transmitter automatically calls the administrator when sound or motion is detected.
Location determination and operation during power failure
In addition to live listening, the device can also transmit the last known location via SMS using LBS technology. The adapter continues to operate continuously as long as it is connected to the mains. In the event of a power outage, an internal battery switches over, providing approximately 2 hours of listening time or up to 24 hours of standby time.
Handcrafted modules for professional use
Unlike mass-produced products, these modules are hand-assembled in small quantities. This ensures maximum reliability, but may also mean the finish may differ slightly from standard 5V USB adapters from well-known brands. This unique, non-machine-made construction makes the device ideal for specialized applications where discretion and reliability are essential.
