Spy Listening Devices for Surveillance


Do you need to gather important information and keep an ear out for critical communication in order to protect your assets and loved ones? Your best option for monitoring rooms, offices, and private spaces is to use spy listening devices.

Endoacustica’s bugging devices are designed to be extremely discreet with their small size and can be placed anywhere in a room. GSM functionality can allow you to add a SIM card to the device. This gives you the ability to listen in on conversations from an unlimited distance as if on a phone call.

How is a Bugging Device Beneficial?
A bugging device is pretty straightforward. All you have to do is insert an activated GSM SIM card in the device and place it discreetly in the room where you want to listen in on conversations. The spy listening device will automatically place a call on your phone when people are talking nearby and you will have full access to the conversation. You can easily control the device through text message-based commands.

This device can be placed in any setting and due to its tiny size, it will be barely detectable. They come in unique forms like a mouse, a wall clock, or a smoke sensor. The person under surveillance can never detect its presence in the room.

If the goal is to do continuous monitoring, you can use a wiretapping device that can be connected to 220V AC and deliver 24/7 surveillance.

Frequently Asked Questions

A Long range GSM audio transmitter allows the user to listen to whatever is happening around the place where it is concealed, through a simple telephone call.

  • Unlimited network coverage
    The GSM room monitoring can be remotely controlled from any location or distance all around the world, bringing the listener and the person under surveillance at a close distance, even though they are thousands of miles apart; all this with a high audio quality by capturing, thanks to its high sensitivity microphone, every conversation or noise around it. No specific receiving device is required, all you need is to make a phone call from any mobile handset. Our GSM bugs come in several shapes and sizes, and can be concealed within different objects of common use, such as home appliances, multiple electricity plugs, table lamps or inside any other object that might do the job. GSM bugs to be used in cars, when installed, do not produce any noise or vibration, making it impossible for your victim to find out that they are being spied upon.
  • Configuration remotely via SMS
    Most of our GSM room monitoring bugs have settings that can be easily changed remotely by sending a simple text message: voice activation, microphone sensitivity level, anti-detection function, and so on… For example, the infrared GSM bug is equipped with a motion and vibration sensor, and can easily be connected to a landline phone.
  • GSM audio transmitter applications
    The unlimited monitoring distance feature makes GSM bugs suitable for being installed in cars, self-powered appliances, electricity plugs and in hidden corners.

A radio analog room monitoring bug, or simply a bug, is made up of a small spy microphone, connected to a miniature radio transmitter, which picks up any audio signals around it and transmits them towards a radio receiver, aptly placed at a distance which.

  • Listening through the dedicated frequency receiver
    According to the transmitters output power, can range within a few tens of meters up to some kilometers; receiver and transmitter must be tuned into the same frequency.
  • Voice activation system VAS
    Our analog audio transmitters can also be equipped with VOX circuitry, which allows for transmission only when there are noises or voice in the room under surveillance, thus allowing for a longer battery life, minimizing the risk of the bug being pinpointed by a bug detector. Furthermore, bugs can feature a remote control unit, which allows activation and deactivation of the bug, in order to make it impossible to locate if the area is being swept by anti-interception devices.
  • Analog audio transmitter applications
    Its ease of use and reasonable cost make it suitable for being used at home or in the office. These small bugs can also be placed inside objects like a cellphone battery, a necklace pendant or hidden inside your clothes.

  • Encripted communications
    A digitally encrypted audio transmitter will transmit a digital radio signal, providing for absolute clarity of sound. Our digital radio bugs use an advanced technology that optimized the transmission quality and most of all, thanks to its encryption method, makes the transmission absolutely impossible to decipher for whoever tries to intercept the digital transmitter signal.
  • Ciphering
    Only who uses a receiver with the proper decryption key can listen to the transmission. Quality digital bugs use spectrum inversion, that is, they cut the signal in millions of little pieces which are then transmitted in so called “bursts”. At the other end of the transmission, the receiver puts these pieces back together, thus making them clear and understandable for the receiver.
  • Digital audio transmitter applications
    Our digital audio transmitters, are used by experts and professionals in the surveillance field, are recommended for governmental agencies or law enforcement.
