The main component of this project is the MAX9814 which is a low-cost, high-performance microphone amplifier with automatic gain control (AGC) and low noise microphone bias. The brain of the project is the Arduino Nano that you can see in the schematic. The complete Schematic diagram for the Arduino Based Spy Bug is shown below. 5V power supply unit (Can be a power bank or so)Īrduino Based Spy Bug – Schematic Diagram.The circuit for the spy recorder consists of very basic components that you will be able to find in your local hobby store, when you have accrued all the components, it can be easily built at home without any complexity. List of Components - Arduino Based Spy Bug Respect other people’s privacy, any misuse of this device might be a punishable offense according to your state law. Important: The project discussed here is only intended for educational use. All this sounds interesting, right? So, let's get started. We also attached an LED with the Arduino that indicates the recording process has started. Once powered up, the recording process will continue until the battery is dead or there is no more space to store the recorded audio. It will able to record audio clips that are 2 minutes long, each 2 minutes long clip would be numbered serially. This project focuses on building an Arduino Based Voice Recorder, which can also be abused as a spy bug. Our spy bug uses a small microphone to record the voice and it stores the recorded voice onto an SD card. Sound activation function and a defined time when the spy audio recorder is to start recording are additional advantages of this small, yet so functional device.Planning to buy a small voice recorder to record voices or sounds in an environment and store them in its memory? Think again! You can easily build your own voice recorder by following a few simple steps. The built-in SD card allows you to record up to 283 hours of recordings. For greater security of the collected data you can protect your DVR-188 digital voice recorder with a password. The recorder is equipped with two independent microphones - a built-in one that collects sounds from a distance of up to 10 metres and an external one for discreet eavesdropping. With the DVR-188 digital recorder you can control conversations conducted on a mobile phone (by connecting it as a headset), as well as on a landline phone (using a dedicated adapter).

You can use it to record, for example, birds singing in the park, and at other times you can use Bluetooth connectivity to record an eavesdropped telephone conversation. The DVR-188 digital voice recorder is a device which is both recording equipment and eavesdropping kit. Particularly noteworthy is the DVR-188 digital voice recorder with Bluetooth, suitable for recording telephone conversations. In the Detective Store's offer you will find digital spy voice recorders of various sizes, both for overt recording and for eavesdropping. Today's digital voice recorders are equipped with a range of features that make recording easier and allow you to get the highest quality sound recording. It's a great tool for capturing words and sounds in a wide variety of situations. You don't have to be a journalist to need a voice recorder. We have plenty on offer for journalists, detectives, special services, hobbyists, business owners and parents.

More advanced recorders offer higher quality sound, password protection, scheduling and timers, overwrite features and much more.ĭetective Store offers miniature voice recorders (coin sized), professional bugs that are hidden in everyday objects, as well as standard digital voice recorders. In addition, sound activation is a common solution that saves power and storage space.
Detective Store offers a range of digital voice recorders for professionals and hobbyists alike, in the form of hidden bugs and normal devices that are ideal for journalistic work.ĭespite huge differences in appearance, size and intended purpose, all digital voice recorders offered by Detective Store are of the highest quality and have a number of options such as built-in long-life batteries, and enough memory to store dozens or even hundreds of hours of recordings. Modern sound recording technology allows microphones to be hidden anywhere and for the device to be completely miniaturised.
