The ELNR-22 system is concealed in a standard remote control case (like a simple gate opener remote control). The striking feature of this device is that it can operate in continuous recording for up to 300 hours (over 12 days), without replacement of the battery or memory card. The microphone of the recorder ENLR-22 is very sensitive and it’s able to record any conversation at a distance of over 10 meters.
Small in size, the ENLR-22 micro recorder is suitable for hidden audio recording operations.The device can work via voice activation system, by timer for periodic programming or with automatic start of the recording; it has four different compression methods, and a sample rate up to 22kHz. All the recordings are stored on a SDHC micro card that can be inserted directly into the PC for file playback or download.
The powerful supplied software allows an easy management of records as well as a smart device customizing and settings. The internal recording circuitry is equipped with automatic gain control (AGC), which attenuates the microphone automatically when it detects a loud sound and increases the sensitivity when detecting subtle sounds. All recordings are saved with the date and time. This is very useful especially to understand when the events of interest have occurred.
