Magnetic GSM Audio Bug; with LIVE listening and Remote SMS
Professionally hand-built in the UK, the GSM Spark is a remote audio listening device which can be called from any smartphone to listen in to the surrounding room or vehicle environment from anywhere in the world. The device supports 3G and 4G for stable, worldwide network coverage. The Neodymium magnetic base provides quick deployment to metal surfaces and a class-leading battery management guarantees to be one of the best standalone GSM listening devices on the market.
CLASS-LEADING BATTERY MANAGEMENT
The GSM Spark is fitted with an 1800 mAh fully rechargeable battery with a super-efficient low power 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 standby time and 15 hours 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.
If you require even longer standby and call times, an external Power Bank (not supplied) can be connected using the PB-A Cable. For example; a Power Bank with a 6'700 mAh capacity will more than double to 50 hours call time over 33 days. The PB-A Cable is optionally available to purchase from the menu above.
3x MICROPHONE AMPLIFICATION WITH NOISE FILTER
Fitted with the one of the finest microphones available using 3x amplification to pick up conversations and sounds over greater distances (25 - 30 feet). The in-built filter helps fade background noise from TV and radio harmonics to enhance the foreground audio, including spoken words.
A thin magnetic neodymium strip is applied to the base of the GSM Spark for fast deployment to metal surfaces. The magnetic strip is isolated from the internal electronic components that would otherwise cause interference with similar inferior products.
3G AND 4G NETWORK COVERAGE
GSM technology is very stable, but networks can be limited in performance depending on the area, especially the older 2G signals. The GSM Spark is built especially for the 3G and 4G networks and fitted with a high gain internal antenna provides broader GSM coverage and a much better performance which comes into its league when the device may be travelling around inside a vehicle. The Spark is the only 4G GSM surveillance device on the market.
BATTERY LEVEL STATUS
Once deployed, access to the device may be minimal, but at some point, you may wish to know the current battery level before retrieving the device to recharge again. By sending a coded SMS from your smartphone to the GSM Spark, you will receive back the current battery status.
MICROPHONE SENSITIVITY ADJUSTMENT
Depending on the working environment, the GSM Spark's microphone can be remotely adjusted to higher or lower sensitivity via coded SMS. This is especially useful if the device is deployed within a small room or vehicle where the loudest microphone level may not be required.
OPTIONAL EXTERNAL MICROPHONE
This is a thin, super flexible anti-glare cable with a 4 mm diameter microphone fitted at the tip of the cable. External microphones are commonly used so the body of the GSM Spark can remain hidden 'out of sight' and, only the tip of the microphone breathes through material or under floors, through ceilings, open cavities etc. The standard length we supply is 125 cm which is adequate for most uses. However, we can provide any length upon request (subject to 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.
CUSTOM DESIGNED MODELS
Each GSM Spark has a rugged ABS enclosure which is hand-rolled in sand and baked to a specific temperature and then sealed with a coating for a unique and luxurious textured finish. We welcome custom builds, for example; different design or larger battery capacity, please contact 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, then please consider the iPhone / Smartphone Mobile Call Recorder. This product connects with any smartphone via Bluetooth and records both sides of the call, storing the conversation to the device's internal memory.
To use the Smartphone Call Recorder, simply enable its Bluetooth and then enable Bluetooth on your smartphone to sync both devices together. Now, when you call the GSM Spark the call can be recorded. Likewise, if you make a call or receive a call to any other mobile, the call can be recorded.
The iPhone / Smartphone Recorder can be optionally purchased from the menu above.
The GSM Spark is a brilliant little surveillance product. It has multiple uses around the home and office either as a security product to actively monitor audio or for gathering much needed audio evidence.
Note: A USB mains plug (not supplied) will be required to recharge the GSM Spark from a mains power supply or, you may optionally purchase a genuine Apple USB mains plug from the menu above. A USB mains plug is not a necessity with this product because the GSM Spark can be charged through a computer, although charging times will take longer.
WHAT DOES THE IMPROVED 3G / 4G NETWORK OFFER?
Unlike most GSM devices which utilise 2G network SIM cards, the GSM Spark is designed to support both 3G and 4G network SIM cards for operational use worldwide. Due to the broader GSM coverage, the signal strength is much more stable and reliable so the device can operate under varied conditions.
WHY WOULD I WANT TO USE AN EXTERNAL MICROPHONE?
This is a thin, flexible anti-glare 125 cm cable with a 4 mm diameter tipped microphone, used when the body of the GSM device needs to remain out of sight so, only the tiny tip of the microphone peeks through material or an open cavity etc. The cable length can be made longer upon request.
HOW DO I CHARGE THE GSM SPARK?
The device can be charged by mains power using a USB mains plug (not supplied) or through a computer USB port. The in-built battery charging indicator confirms when the unit is charging and when fully charged.
WHAT IS THE STANDBY AND CALLING TIME?
The power management uses just 0.3 mAh of battery when the GSM Spark is in standby (standby = switched ON but not listening), and just 120 mAh battery when listening. Under tested conditions this equates to a standby time of approx 25 days and a calling time of approx 15 hours per charge. In real term use, splitting the balance, you should expect 10 hours of call time over a two week period.
CAN THE BATTERY PERFORMANCE BE INCREASED EVEN FURTHER?
Yes. By optionally purchasing the PB-A Cable from the menu above, an external Power Bank can be connected (not supplied) to increase the battery performance substantially. For example; calculations using a 6'700 mAh Power Bank will increase the battery to 33 days standby and 50 hours call time.
IS IT POSSIBLE TO REMOTELY CHECK THE BATTERY LEVEL?
Yes. You can send a coded SMS to the GSM Spark to receive the device's current battery status. This is especially helpful so that you can retrieve the device and recharge.
WHY IS THE GSM SPARK MAGNETIC?
The magnetic aspect provides a more varied usage, including metal surfaces; therefore, it can be deployed 'out of sight' if required.
HOW EASY TO LISTEN INTO MY OWN PERSONAL ROOM SPACE?
No technical skill is required to use this product - the GSM Spark is supplied ready to work out of the box. Simply by calling the associated SIM card number from your smartphone opens the highly sensitive microphone of the device so that you can clearly hear the surrounding environment.
CAN I ADJUST THE MICROPHONE LOUDNESS?
Yes. You can send a coded SMS to the GSM Spark to lower or higher the microphone sensitivity. This is especially helpful depending on the size of the room or environment the device is deployed within. For example; a small space may not require the highest microphone sensitivity.
HOW FAR AWAY CAN I MONITOR SOUND?
You can be anywhere in the world. There are no range restrictions providing your smartphone has a good GSM signal is a good GSM signal.
ARE THERE ANY BAD INTERFERENCE LIKE BUZZING NOISES WHEN I LISTEN IN?
No. The microphone is one of the best in the industry with 3x amplification allowing you to listen to conversations or sounds at a greater distance. The in-built noise buffer also helps smooth away background interference to improve audio clarity.
IS IT POSSIBLE TO RECORD AUDIO I HEAR?
Optionally, we offer the Smartphone Call Recorder, which is a product that uses Bluetooth to sync with a smartphone to then record the call. The Smartphone Call Recorder will record both sides of a typical mobile call and then stores the recorded call to the devices internal memory.
