GSM Enduro Live Listening Device

The GSM Enduro Live Listening Device is a longterm audio bug, with deployment magnets, that can provide the ability to listen ‘live’ to what is happening in the environment where it has been placed without the need to have a permanent mains power supply.

Superb Microphone – Discreet Auto-answering with this Listening Device

As with all GSM Bugs, the GSM Enduro Live Listening Bug requires a mobile phone SIM card inserted within so that it can be called from anywhere in the world, if required. When the number of the inserted SIM is contacted, the device will, without alerting attention in any way, auto-answer the call and open up its in-built sensitive microphone which will enable the caller to listen into the surroundings up to 10 metres away from where the GSM bug has been placed. The device does not require credit on the SIM card to receive the call, however it is worth noting that if using a Pay-as-you-go SIM then after a period of time the SIM supplier may cut off the SIM card from the network because that SIM is not actually making them any money.

This amazing GSM listening bug unit delivers simply fantastic audio quality, strong deployment magnets in a nice such compact enclosure. As an alternative to the standard internal microphone, an external wired microphone is now available, with the same microphone at the end of a one metre long flexible cable – ideal when you wish to hide the main base unit away from view, yet still maintain the microphone in the optimum position for effective listening (a cost option).

Exceptional Battery Saving Technology

The major limiting factor with most small stand-alone spy devices is the battery life. The GSM Enduro listening device is exceptionally compact, but still manages to function for an impressive period of time. The internal lithium ion rechargeable battery pack will give a combination of up to 14 days standby time and up to 16 hours of listening-in time (optimum conditions), outstanding figures for such a device.

A Listening Bug Made for Discreet Deployment

Like most of our listening devices, this GSM device has quad-band capability which means that it can be used in every country worldwide.
The unit is best deployed in a position where it can pick up sounds in the environment where it has been placed. If placed in a room in a house, then a surface above head height would be ideal where it would be less likely to be discovered (possibly on top of a cupboard or curtain pelmet). In an office then maybe the opportunity to use the attached magnets to attach to the metal frame of a desk. If hidden inside a vehicle then a good position maybe secured under one of the front seats where the device would still pick up on sounds inside the vehicle, but remain out of sight.

Battery or Optional Mains Power

The internal lithium battery in this listening device can be recharged using the supplied magnetic USB lead for subsequent stand-alone deployment or it may be possible in some circumstances to leave the charge lead connected to the GSM Enduro listening bug for longer deployment as long as the mains power supply remains on.

Should the mains power supply get switched off, then the unit will then revert to taking power for the internal battery, which would then have a full charge. The device has an external on/off switch so the battery can be also charged and the unit remain switched off until deployment.

NB:THIS PRODUCT USES 2G GSM MOBILE PHONE NETWORK, WHICH HAS NOW BEEN SWITCHED OFF IN USA.

Potential Circumstances for Use

The GSM Enduro Live Listening Device maybe an ideal solution for keeping an eye your children or an elderly relative for their protection and safety. Customers may find the product to be useful in their own personal protection and in gathering evidence of abuse against them. Employers may have a need to monitor employees suspected of illegal or inappropriate activity whilst they are engaged in working for the company.

Would the GSM Enduro still pick up sounds if it was on top of a cupboard or underneath a low settee?

As long as the device is in the airspace of the environment where conversation is taking place and the microphone holes are not covered, then it will pick up on these voices (within the sensitivity range)

If the battery expires during use, will the unit make any sounds to indicate that the battery is about to go?

The unit is totally covert. The unit will give no visual or audible indication of the battery’s expiration.

Will this device work outside the UK?

This listening unit has a quad-band modem and therefore will work anywhere around the world on the GSM networks 850, 900, 1800 and 1900MHz bands.

Will this unit take any GSM SIM card?

These units have been designed to accept standard size 2G SIM cards from any network, although of course it has been impossible to test every network SIM provider around the world and these are designed for the 2G network so in the UK 3 Network SIM’s cannot be used.

If I left this on a desk, would it be obvious what it was?

Although the device is not immediately a giveaway, a simple examination by somebody with basic common sense would reveal that it was more than a plain black box. It is best to place it in a position out of immediate view.

Can I call the unit from any phone (mobile or landline phone)?

Yes, the unit will accept calls from both types, but to make use of the voice activation facility only a mobile phone can be used.

You will need to consider the following to use this equipment:

• You will need a working mobile phone to enable you to listen in to the bug and control its features.
• This unit can take permanent power from the mains and remain switched on ready to use.
• The device does not require credit on the SIM card to receive the call, however it is worth noting that if using a Pay-as-you-go SIM then after a period of time the SIM supplier may cut off the SIM card from the network.
• Just like any mobile phone the GSM Enduro can lose network signal from time to time, especially when deployed inside a moving vehicle that is travelling through varying signal strength areas.
