AI-Powered Hearing

The phone you stopped using, now smarter than ever. RECAM captures audio events like glass breaking, a door slamming, or a baby crying — and classifies them locally in milliseconds. Everyday sounds like traffic or rain? Automatically filtered out. It’s AI CCTV that listens too — not just watches.

  • 🎧 More than 40 sounds you can arm one by one, detected in real time.
  • ⚙️ All processing happens on-device for total privacy.
  • 🚫 Fewer false alarms — everyday noise is filtered out.

40+ sounds RECAM can detect

More than 40 sounds you can switch on one by one. Each profile (Baby, Home Security, Pet) arms a sensible set by default; add or remove any sound from there.

  • Home security: glass breaking, door slam, knock, doorbell, footsteps (someone walking or running), shout, yell, screaming, smoke detector, sirens (police, ambulance, fire engine, emergency vehicle), gunshot, fireworks, fire crackling.
  • Baby: baby crying, crying and sobbing, baby laughter, giggling.
  • Pets: dog bark, dog growl, dog whimper, cat meow, cat purr.
  • Around the house: speech, chatter, whispering, laughter, telephone ringing, ringtone, alarm clock, running tap, drill, hammer, saw, power tool, hedge trimmer, wood cracking, chopping wood.

A listener, not a sound identifier. RECAM listens on the camera device at home and alerts you when one of these sounds happens. It isn’t an app you play a recording to so it can name the sound. Detection runs on that device; audio isn’t uploaded for analysis. Sound alerts are part of RECAM Pro.

Perfect for Nights and Quiet Rooms

Even when your camera view is dark, RECAM never sleeps. The app listens intelligently to your surroundings, detecting unusual sounds and sending you an instant push notification — whether you’re at home or miles away.

Paired with motion detection, RECAM covers what the camera can’t see and keeps listening around the clock, even in total silence or darkness.

More Awareness, Less Noise

Meaningful alerts only. You choose which sounds RECAM listens for, and each profile (Baby, Home Security, Pet) arms a sensible set by default. Anything you haven’t switched on, like a background hum or the rain, doesn’t trigger an alert. The result: fewer, more meaningful notifications when something truly needs your attention.

Combine sound and motion detection so RECAM alerts you to what the camera sees and what it hears.

Let RECAM Listen for You

Security doesn’t have to be complicated. With AI-powered hearing and end-to-end encrypted streaming, RECAM makes a spare phone a discreet, powerful listener that keeps you informed and in control.

FAQ

What sounds can RECAM detect?

More than 40, including glass breaking, door slams, knocks, the doorbell, smoke detectors, sirens, screaming, a baby crying and a dog barking. You switch each sound on or off, and everything is processed on the camera device.

Will RECAM send too many alerts?

No. RECAM intelligently filters background noise like traffic or rain, sending only meaningful notifications when something important happens.

Does sound detection work in the dark?

Yes. Even if the camera can’t see, RECAM listens for anomalies 24/7, ensuring awareness during nighttime or low-light conditions.

Is RECAM a free sound detection app?

Free to start. Sound detection runs on the camera device itself, and for your first 3 days the alert tells you what it heard, with live video too. After that, alerts that name the sound and the live view need RECAM Pro ($4.99/month or $49.99/year); without it, you still get a notification that something was detected.
