Mini Wi-Fi voice recorder with long battery life AR02

Mini Wi-Fi Voice Recorder (Listening Device) with Long Battery Life is a compact Wi-Fi voice recorder equipped with a powerful 3000 mAh battery, an external microphone, and remote control via a mobile app. Compared to the AI-AR01 model, it offers a significantly higher battery capacity, allowing the device to operate for approximately 37.5 hours of continuous recording, while in the power-saving standby mode the battery life can reach up to approximately 125 days. The Mini Wi-Fi Voice Recorder connects to a Wi-Fi network and then allows you to use the available remote functions via an app for Android and iPhone. Initial setup is made easier by Bluetooth pairing. The device offers three operating modes, including two power-saving modes with sound activation. Recordings in WAV format can be stored on a microSD card with a capacity of up to 128 GB, while cloud storage is also supported. The external microphone helps capture surrounding sounds more effectively and has a stated recording range of approximately 5 metres. Another advantage is recording while charging, which allows the device to be used while connected to an external power source. Thanks to its compact dimensions, this Wi-Fi voice recorder with long battery life is suitable for recording your own notes, business meetings, lectures, or conversations where you are authorised to make an audio recording.

Three Recording and Power-Saving Modes

The Mini Wi-Fi Voice Recorder (Listening Device) with Long Battery Life offers three operating modes, allowing you to adjust the recording method according to the required battery life and intended use.

1. Continuous Recording Mode

In this mode, the device can continuously record audio and also supports loop recording. When connected to a network, the available live audio functions can be accessed through the app. Thanks to the 3000 mAh battery, the operating time during continuous recording is approximately 37.5 hours.

2. Power-Saving Mode A

The standby power consumption of the device is approximately 1.6 mA. When sound is detected, the recorder can automatically activate recording and send a notification to the app. Depending on device availability, remote access to live audio can also be used in this mode. Standby battery life can reach approximately 78 days.

3. Power-Saving Mode B

The most energy-efficient mode reduces standby power consumption to approximately 1 mA, allowing a standby time of up to approximately 125 days. In this mode, live audio is available through the app for approximately one minute after each sound-triggered activation of the device. When sound is detected, the device can start recording and send the corresponding notification.

Wi-Fi Connectivity and Remote Control via App

Integrated Wi-Fi connectivity allows the Mini Wi-Fi Voice Recorder to connect to a compatible wireless network and subsequently use its available functions through a smartphone app. The app is available for Android and iOS phones. Initial setup is simplified by Bluetooth pairing, which speeds up device configuration and connection to the Wi-Fi network. After successful setup, functions such as recording settings, sound activation, and notifications can be used depending on the selected operating mode. For remote access, the recorder must have a working internet connection.

3000 mAh Battery and Standby Time of Up to Approximately 125 Days

One of the main advantages of this model is its integrated 3000 mAh battery. In continuous recording mode, it provides approximately 37.5 hours of operation. If continuous recording is not required, one of the two power-saving modes can be used. Mode A offers a standby time of approximately 78 days, while Mode B can provide up to approximately 125 days of standby time. Actual battery life depends on the number of sound activations, use of live audio and Wi-Fi connectivity, signal quality, device settings, temperature, and the current condition of the battery.

External Microphone, microSD Card and Recording While Charging

Unlike the basic model, this Wi-Fi voice recorder is equipped with an external microphone, allowing more flexible microphone placement and effective capture of surrounding sounds. The stated audio recording range is approximately 5 metres. Recordings are stored in WAV format at a bitrate of 128 Kbps. The device supports microSD memory cards with a capacity of up to 128 GB, with one minute of audio recording requiring approximately 1 MB of storage space. Cloud storage is also supported. A major advantage is the ability to record while charging, meaning that when connected to a suitable external power source, the operating time does not have to be limited solely by the capacity of the internal battery.
