GSM Audio Listening Black Box Bug; with Real-Time Audio and Sound Detection

This intelligent little GSM audio product allows you to remotely listen to the room | vehicle environment when you are absent from the premises.  Ideal for home | office security to notify you in the event of an intrusion or when people enter a specific environment, they should not be in.  You may call the GSM Black Box's pre-fitted SIM card from anywhere in the world, and the powerful, in-built microphone permits real-time audio listening up to 25 feet from where the device is situated.

SUPPORTS 4G COVERAGE (coming soon)

We provide both 2G and 4G models, depending on your country.  For example, the UK uses 2G, 3G, and 4G networks; therefore, no upgrade to the 4G model is required.  Customers including the USA, Australia, Japan, Saudi Arabia etc will need the 4G model.  Overseas countries should check their associated GSM network supports 4G voice calling.


When the correct SMS command is sent from your smartphone, the GSM Black Box will enable room monitoring for audio sounds above 50 dB (average room environment level) and, in the event of sound detection, will notify your smartphone by SMS alerting you of a potential occupancy within that area.

Note: A pre-fitted SIM card is supplied; however, the Sound Detection feature will require you to top-up and maintain credit to use this feature actively.


As with all our GSM audio surveillance products, the GSM Audio Listening Black Box is a cut above the mustard, offering exceptional audio clarity without the humming and crackling noises associated with inferior products.

The Black Box has a decent standby time of 7 days (per charge), given the device's small footprint.  Standby time = the amount of time the device is switched ON and ready to receive your call to listen (but not actively listening).  When calling the GSM Black Box, this is classed as 'talk time' and will reduce the overall standby time.  We recommend careful battery management or perhaps opting for a mains-powered GSM product for an infinite operational time?

To recharge the GSM Black Box, connect the supplied USB cable to the device and the other end to a USB mains plug.  The option to purchase a genuine Apple USB plug is available from the menu above.


In some cases, you may wish to record the audio heard on your smartphone.  Consider the iPhone / Smartphone Mobile Phone Recorder.  The Smartphone Recorder will pair with any Bluetooth 3.0 enabled smartphone so that the room environment you are listening to can be recorded onto the Call Recorder device for evidence.  The Smartphone Call Recorder can also record regular conversations to and from your smartphone.  See the 'More Information' tab for further details.

The iPhone / Smartphone Recorder can be optionally purchased from the menu above.

More Information



The GSM Black Box measures just 45 (H) x 30 (W) x 15 (D) mm - and small enough to be placed within a room or vehicle environment to monitor audio for evidential purposes or for the general security of your property when you are absent.


An internal fully rechargeable battery provides up to 7 days of standby time.  Standby time = the device is switched ON and available for you to call in from a smartphone.  Please bear in mind that each time you call the device, this is classed as 'talk time' and will reduce the overall battery performance - and if the voice-activation feature is enabled, battery consumption is higher because the microphone is constantly monitoring for audio changes above the pre-set 50 dB sound level.


Switch ON the device and place it on a shelf, behind a bookshelf etc.  The device can remain out of sight, but the microphone must be allowed to breathe openly in the room environment.  You may call the associated SIM card fitted inside the GSM Black Box at any time and your call will automatically connect and open the microphone for audio listening.


Your location can be anywhere in the world providing your smartphone has a good GSM signal.  You can also call the GSM Black Box using VOIP.  When you are actively listening on your smartphone to the room environment, the microphone on the GSM Black Box is capable of picking up audio approx. 25 feet away from where it is situated.


This depends on which networks your countries support.  If your country supports 2G there is no requirement to purchase the 4G model.  Please check that SIM cards in your country support 4G voice calling before upgrading to the 4G model.


No.  Unlike other inferior products, our GSM Black Box provides excellent clear audio.


This is a security feature that can be enabled | disabled by sending an SMS command from your smartphone.  When this feature is enabled, the GSM Black Box's microphone will actively monitor the room environment for sound above a normal 50 dB level and then send an SMS notification to your smartphone alerting you that noise has been detected.  This feature is ideal for use when you wish to be notified should somebody enter your premises when you are not there.

Please note the sound detection will consume 50% more battery performance due to the microphone constantly monitoring audio levels.  This will reduce the 7 days standby time to approx. 3.5 days.


Yes.  We offer a separate iPhone / Smartphone Mobile Phone Recorder product that can be used with the GSM Black Box to allow you to record what you hear on your smartphone.  The Call Recorder uses Bluetooth 3.0 to pair with a smartphone so that the room environment that you are listening to can be recorded onto the device.  The Call Recorder can also record and store normal conversations to and from your smartphone too!
