AllSeeing's SHARK contains low-noise amplifiers which delivers gains up to 80dB, enabling clear object  detection at 2km range.

It offers sensitivity of -8 dB (XLR mono) and -12 dB (XLR stereo) at 1 kHz, with a signal-to-noise ratio of 98 dB (mono) and 83 dB (stereo).

With low self-noise (-4 dBA @1 kHz) and max input levels up to 108 dB, ensuring high-fidelity acoustic surveillance.

 

SHARK is capable of locking unto an acoustic signatures (i.e., drones) up to 2000 meters.

Its parabolic reflector focuses sound onto matched low-noise microphones, achieving a gain of up to 50dB in the focal range and a frequency response from 100 Hz to 20 kHz. This enables detection of high frequency harmonics (i.e., propeller harmonics) between 1Khz – 10KHz, with mono-stereo directivity allowing for effective discrimination from background noise. 
 

SHARK is provided with a versatile Command and Control (C2) center which employs an Artificial Intelligence (AI) Convolutional Neural Network (CNN) trained on log-Mel spectrograms of audio inputs to detect sonic events.

The software is pre-trained on hundreds of acoustics signatures, as it detects both current and future events. Training on the field is also available to fine tune the device to unique conditions. The direction and velocity of the tracked object is then calculated based on sonar Doppler math.

At low frequencies (<1 Hz), SHARK detects harmonics (engine, motor and blade harmonics) while high-frequency (>1KHz) response enables identification of subtle mechanical tones and harmonics up to 20 kHz.

The parabolic design enhances directionality and gain across the full range. With the higher sonic frequencies being more directional. Multiple SHARKS synchronized together or single SHARK can be placed on a motorized scanning mount for direction and distance finding.
