Product Description

This acoustic camera visualizes the location of sound sources, overlaying them onto a black-and-white visual image captured nearly simultaneously.

• Resolution: With an often-larger microphone baseline than many competitors (larger baseline improves resolution) the sound camera has a maximum angular resolution of 3.4°, with beamwidth inversely proportional to frequency (approximately 8° beamwidth at 10 kHz). Note, pointing accuracy is often much better and improves with better SNR of the source.
• Field of View (FOV): Large FOV at ~70° horizontal × ~40° vertical displayed on an often-larger screen.
• Audio Capture: 16-microphone array recording at 48 kHz for 0.2-second intervals.
• Frame Rate: Up to 3 Hz with approximately 0.7-second visualization lag, depending on user settings.

Typical Applications Include:

• High-frequency leak detection in multi-source environment.
• Locating crickets, birds with high-frequency calls (e.g., smaller songbirds — owls generally fall below useful frequency range)
• Wildlife monitoring
• Detecting nearby drones

Example images show sound imaging from a sprinkler, compressed air can, and a cricket. The system can determine line of sight for some very high-frequency bird calls (example image of a tree shown).

What’s Included:

• Acoustic array with integrated mounting system
• Tablet preloaded with necessary software
• Cables & Power Adapter
• Hardened carrying case

Tripod and handgrips in images not included (standard 1/4-20 thread supported — tripod highly recommended).

System Operation Highlights:

• Boots in approximately 1 minute
• Only 6 sensitivity controls needed to adjust imaging responsiveness
• Frequency range and dominant components automatically detected and visualized — a spectral plot is shown alongside the acoustic image with red dashed bounds indicating active imaging range
• Plug in only 2 cables, setup complete and ready to boot

Design Notes:
This unit is engineered for affordability without sacrificing core functionality. Possible through leveraging Ph.D.-level expertise in Fourier synthesis imaging adapted from radio astronomy.

Additional Notes:

• Some images on this page may show the earlier model; software and visuals have since been improved.
• Units are new but undergo testing and calibration prior to shipping. System production is also being iteratively improved with additional units sold.
• If a specific mounting color is required, custom builds are available on request.
