GSM Audio Listening Black Box Bug; with Real Time Audio Listening

This is a great little listening product - simply dial the SIM card (supplied) from your mobile phone to the little black box to clearly listen into the surrounding environment with the same super audio clarity as our other professional GSM items.  The powerful microphone is one of the best in the industry allowing you to monitor audio in real time some 25-30 feet away from where the device is place - and from anywhere in the world you may be!


In addition to the fantastic audio listening quality, the sound activated feature of the Mini Black Box Pro will text message your mobile phone in the event of detecting sound, so you can then dial in and monitor the situation.  The microphone has three (3) microphone sensitivity settings which can be adjusted by sending a coded SMS.

Please Note: We will supply a pre-fitted SIM card however, if you purchase the optional Sound Detection feature which notifys your mobile phone when sound is detected then you will need to top-up the SIM card with credit (or any SIM card you use) in order to use the Sound Detection feature.


As with all our GSM audio surveillance products, this Mini Black Box Pro is a cut above the mustard offering exceptional audio clarity without the humming and cackling noises associated with other inferior products.

The device can be placed within almost any room or vehicle environment and with a decent standby time up to 10 days before a recharge is required.  Obviously, please bear in mind that when calling the device to listen, this is classed as 'talk time' and will inevitably reduce the overall standby time.

To recharge the GSM Black Box the supplied USB cable is connected to the device and the other end to a USB mains plug.  If you do not have a mains USB plug to hand, the option to purchase a genuine Apple USB plug is available from the menu above.


If you wish to record the audio that you can hear through the GSM Audio Listening Black Box then please consider the iPhone / Smartphone Mobile Call Recorder.  This product syncs with any mobile phone using Bluetooth so that the room environment that you are listening can be recorded onto the device.  It can also record and store both sides of a mobile phone conversation to the devices internal memory.

Simply enable Bluetooth on the Smartphone Call Recorder and enable Bluetooth on your mobile phone and sync both devices together.  Now, when you call the GSM Audio Listening Black Box the call can be recorded.  Likewise, if you wish to make or receive any mobile phone call and record the call/s it is now possible.

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

More Information
How small is the black box?

This little portable GSM black box measures just 45 x 30 x 15 mm, therefore, can be easily placed within the room environment you wish you monitor for audio.

How is the black box powered?

The internal lithium battery combined will provide up to 10 days standby time.  This means it can remain ready for you to call in and listen for up to 10 days.  Please bear in mind each time you do call in this is classed as 'talk time' and will reduce the overall battery performance.  Likewise, when the device notifies you of sound, more battery consumption is being used so its highly unlikely you will actually get 10 full days.

How do I listen into my personal room?

Simply switch the device ON and place on a shelf behind a book etc.. Whenever you need to hear, simply call the associated SIM card inside the black box and your call will be automatically connected.

How far can I monitor events?

You can call the black box from the other side of there world if you wish - there are no range restrictions as long as the GSM coverage of your mobile phone is good.  When you are listening in, the microphone of the black box is capable of picking up audio some 25 feet away from where it is placed.

Are there any interference fuzzing noises when listening in?

No.  Unlike other inferior products, our GSM black box provides unquestionably excellent clear audio.

What is the sound detection feature?

This is a great security feature which you can activate ON / OFF by sending a simple coded text message from your mobile phone to the black box.  Once enabled, the microphone will actively monitor the environment for audio and then send you an SMS to your mobile phone once audio is detected.  This is ideal for using as a security device if you wish to be alerted when somebody enters your premises for example.  In addition, you can also change the sensitivity level from Low / Medium  / High to match the environment in which the device is placed.

Please note that activating the sound detection feature will use around 50% more battery performance die to the microphone constantly monitoring audio levels.

Can I record the audio too?

Optionally, we offer a product which uses Bluetooth to sync the device with any mobile phone so that the room environment that you are listening can be recorded onto the device.  It can also record and store both sides of a mobile phone conversation to the devices internal memory.

For further details please navigate to the Smartphone Call Recorder found under Audio Surveillance ---> Call Recording.

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