## Summary

This video is a hands-on review of the TD2E acoustic imaging camera, an $800 device that visualizes sound sources in real time. The presenter demonstrates its core features, including a 64-microphone array, frequency range, and photo capture, while also noting a discrepancy in the advertised ports.

### Key Points

- **Product Introduction** [00:02] — The TD2E acoustic imaging camera costs $800 and comes with a 5,000 mAh rechargeable battery that slots into the bottom.
- **How It Works** [00:18] — The camera uses 64 microphones to detect sound direction and overlays the location on the screen, pinpointing sound sources accurately.
- **Demonstration with Tone** [00:31] — Playing a 9,000 Hz tone from a single phone speaker shows a spike at that frequency, proving the device's accuracy.
- **Frequency Range** [00:46] — The device picks up frequencies from 2,000 Hz up to 100,000 Hz, covering beyond human hearing range, useful for inspections.
- **Photo Capture Feature** [01:11] — Pulling the trigger captures a single 0.3 megapixel photo onto a micro SD card, located under a flap labeled micro SD, USB, and HDMI.
- **Port Discrepancy** [01:24] — Upon opening the flap, the presenter finds the micro SD and USB ports but no HDMI port, contradicting the label.

### Conclusion

The TD2E acoustic imaging camera is a powerful tool for visualizing sound, offering high accuracy and a wide frequency range. However, the missing HDMI port is a notable discrepancy that may affect connectivity expectations.

## Transcript

mind-blowing. >> Okay. Yeah, I have to try this. So, I TD2E acoustic imaging camera, and it's $800. what it looks like. It's pretty crazy. It comes with this, which is a 5,000 mAh
rechargeable battery that slots into the bottom. And it absolutely works. You can see where sound is coming from. And it's really pinpoint accurate, too. makes noise, especially if it's like a constant noise, it uses these 64
where the sound is coming from and overlay the location on the screen. So, just me talking. So, it just puts it over my mouth, obviously. But here's what it looks like playing a 9,000 hertz tone from a single phone speaker. And
you can see that spike in that specific frequency. This can pick up from 2,000 frequency. This can pick up from 2,000 htz up to 100,000 htz. So, it's starting of the range of human hearing. So, it can pick up things that your ears can't
detect and show you exactly where they're coming from. Not in like a ghost type of way, more of like a inspections type of way. That's also why it has this really bright light on it. Uh, there's also a trigger here. Pulling that
trigger is hilarious. All it does is capture a single 0.3 megapixel photo onto a micro SD card, which should be at the top here under this flap where it says micro SD, USB, and HDMI. But then I opened it and I see the micro SD and the
opened it and I see the micro SD and the USB, but no HDMI.
