Spark Magnetic GSM Audio Listening Bug

Professionally designed and hand-built in the UK, the GSM Spark is a remote audio listening device that can be called from a smartphone to listen clearly to the surrounding room or vehicle environment anywhere in the world.  The product supports 4G for stable, worldwide network coverage.  An ultra-thin Neodymium magnetic base provides quick deployment to metal surfaces, and a class-leading battery management guarantees one of the best standalone GSM listening devices on the market.

WORKS STRAIGHT OUT OF THE BOX

The GSM module is designed to accept most SIM cards straight out of their packet to slot straight into the device.  The module handles the initial mundane network processes and text messages when fitting a new card.  An LED then indicates when the device is ready to use.

3x MICROPHONE AMPLIFICATION WITH NOISE BUFFER

The sound quality is extremely clear and fitted with one of the finest microphones with 3x amplification.  A built-in noise filter fades the background from a TV/Radio, concentrating on the foreground audio of spoken words.

The audio sound is boosted further with superior clarity if you insert a pair of Apple AirPods.  You will hear a big difference between listening on your smartphone and listening through a pair of Apple AirPods.  Conversations are easily picked up at distances exceeding 30 feet, depending on the room ambience.  Other brand earphones may be equally as good.

SOUND DETECTION FEATURE

Depending on the working environment, the GSM Spark's microphone can remotely monitor the surrounding audio levels and trigger a notification to call your smartphone when sound is detected above -40db (the normal room acoustic level without noise).

Note: Enabling the Sound Detection feature will absorb more battery performance because the microphone consistently monitors sound levels.

CLASS-LEADING BATTERY MANAGEMENT

The GSM Spark is fitted with an 1800 mAh fully rechargeable battery with a super-efficient battery management drawing just 0.3 mAh during standby (standby = switched ON but not calling into the device) and 120 mAh during call time.  Under bench test conditions, these calculations equated to a performance of 25 days of standby time and 15 hours of call time (per charge).  In real-term usage, by balancing the calculations, please expect a fully charged GSM Spark to provide 10 hours of call time over two weeks - quite exceptional performance for such a small battery-powered device.

Note: The GSM Spark can be connected to any external Power Bank for longer operational use.

MAGNETIC DEPLOYMENT

The GSM Spark can be deployed in many environments, and a thin magnetic neodymium strip is applied to the base for attachment to metal surfaces.  The magnetic strip is isolated from the internal electronic components that would otherwise cause interference.

OPTIONAL EXTERNAL MICROPHONE | POWER BANK

The external microphone is a thin, super flexible anti-glare cable fitted with a 4 mm diameter microphone at the cable's tip.  External microphones are commonly used so the body can remain out of sight, and the tip of the microphone breathes through material or under floors, ceilings, open cavities etc.  The standard length is 160 cm, which is adequate for most uses.  However, we can provide any length (subject to a fair additional cost).  An external microphone isn't required for regular use and is best suited to field operatives as part of a varied surveillance kit.

In addition, the GSM Spark can be connected to any external Power Bank to increase the overall working time.  The Power Bank we offer is 10'000 mAh, one of the smallest and lightest portable Power Banks for the capacity.  The Power Bank can also recharge smartphones and tablets and is a handy travel accessory to keep in the glove compartment.

CUSTOM DESIGNED MODELS

Each GSM Spark has a rugged ABS enclosure, sealed with a unique coating to provide a luxuriously textured finish.  We welcome custom builds, for example, different designs or larger battery capacity, please get in touch with us, and we will try to accommodate your needs.

RECORD THE AUDIO

If you wish to record the audio that you can hear from the GSM Spark, consider the iPhone / Smartphone Mobile Call Recorder.  The Call Recorder is a super handy device that connects to a smartphone via Bluetooth to record and store both sides of the call in the Call Recorder's internal memory.

To use the Smartphone Call Recorder, enable Bluetooth and then enable Bluetooth on your smartphone to sync both devices together.  The call can be recorded when you listen into the GSM Spark and if you want to record your mobile incoming and outgoing calls too.

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

The GSM Spark is a brilliant little audio surveillance product.  It has multiple uses around the home and office as a security monitoring product to gather much-needed evidence when you are absent.

Note: A USB mains plug (not supplied) will be required to recharge the GSM Spark from a mains power supply, or you can purchase a genuine Apple USB mains plug from the menu above.  This product does not need a USB mains plug because the GSM Spark can be charged through a computer, although charging times will take longer.
