That isn’t how these things work, and there would be no RAM space available for such a thing.
There is a ISO IEC standard for the pattern, and if other devices don’t stick to the standard, it makes it exceedingly difficult to detect these things. *edit, I mean, if they did do any processing on the incoming waveform, but they don’t, which is why I said it isn’t how these things work.
You can’t be more wrong! The cameras don’t monitor dB level. Check your facts, before saying things that are not true. The standard sounds are T3 and T4. Unfortunately, I couldn’t find a sample, except trying with every alarm sound found on YouTube…
Regarding dB level, I guess you got me wrong. The cameras have 2 distinct sound triggers: sound and alarm. The first triggers when every sound is captured, while the second monitors specific smoke and CO alarm. Check the app settings!
As I said, a simple kids whistle was enough to set off a “fire” alert, as did the delivery truck, though, now you got me curious, perhaps some minimal processing is going on, but there is no way these do waveform matching
If anything it would be db levels and perhaps period as well.
Hi, @serban! I’m the person from Twitter and I was able to get files for this for you today. Still can’t find them on YouTube (which I think is weird). Here’s a file with the samples I pilfered from the devs.
We’re working on making this more reliable so if you’re having false alerts, @ShadowCam, please let us know!
I wonder how these T3/T4 are standard sounds, because all smoke alarms on the market just beep continuously multiple times, without that break… I even heard multiple smoke alarms in American movies and none of them beep like T3/T4, but continuously multiple long beeps…
Apparently it was due to the National Fire Protection Association to make sure that there was a standard sound that indicated a whole building evacuation was necessary. It looks like it was first published around 1999 in the NFPA 72, National Fire Alarm Code. So there are some variations but this is the standard version that is more likely to be found in multiple homes/buildings.
Can someone from Wyze give us some insight into how this smoke alarm sensor works? Is it just a db sensor as Shadow suggests? Or something more complex? Surely it’s listening for a specific pattern that could be plotted on a spectrogram?
Getting Wyze to ‘learn’ the sound of your different alarms is a great idea IMO.
So you’d activate the alarm that you want Wyze to learn, then press a button to record that particular alarm sound within the app.
You’d then upload it to the device, so when it hears that specific sound wave pattern it can alert you. A beep of a reversing truck may have exactly the same spectrogram pattern as my UPS alarm… which is unlikely, and unlucky, but if it is, I’d more than happily get a notification of that rather than nothing at all.
It’s already listening for the pattern of a smoke alarm (supposedly), so this is just telling the device to listen out for a few other (pre-recorded) beeping patterns too…?
What i had in mind was adding a way to have the camera learn then listen for some custom tone/sound like the notification sound my clothes washer makes when it finishes.
This way the wyze app can notify the user when the clothes are done washing.
Audio Detection of Smoke and fire and CO alarms doesn’t trigger when Google Nest Protect alarm rings and audio alarm detection is on. This appears to be a bug in both my Wyze Cam v2 and my Wyze Cam Pan.
Please consider adding audio support/recognition to the Wyze cameras for the very popular Google Nest Protect smoke and CO alarms.
Allow the ability to set custom alerts and notifications. This includes the ability to have a separate alert/tone for motion vs sound. It also includes the ability to have a custom alert for the smoke/CO2 function - the ability to have a louder and more prominent alert for this would be great.
