Bit offtopic but still worth mentioning for future reference is that when you count seconds out loud, start from 21.

What it does is this ensures the numbers are closer to 1 second duration because the amount of time it takes to mention the 2-3 syllables whereas the early ones { 1, 2, 3, 4, 5, 6, 8, 9, 10, 12 } are merely 1 syllable.

Why 21 and not 13? Its an easy to remember number (just add 20 to your starting count), and the second part of the number is still accurate.

Don't believe me? Feel free to verify with a stopwatch.

I learned this from driving lessons in NL. Based on some quick translation abracadabra it seems to equally apply to English.

(NB: To be precise, 9 would be 2 syllables in Dutch while its only 1 syllable in English. Other languages will vary!)

I've been using MotionEyeOS for several months now. I setup a a couple of Pi3's with some cheap Logitech USB webcams. Works great from inside the house - I used velcro to tape the cameras pointing out from various windows around the house and in the garage.

I am looking for something that will work outside and has night vision though.

Or use old cell phones: http://www.cloxmonkey.com/securitysystem.html

The "bad ESN" LG's mentioned in the article appear to be $15 including shipping now; you can get a lot more for the $35 cost of a zero + camera module.

The Android app mentioned does not appear to specifically try to be compatible with the Echo Show yet.

I've toyed around with a couple of these for use as baby cams -- mostly streaming the video feed over RTSP using VLC as the server. The video feed always works well, but I've never been able to get the audio from a usb mic to transmit using this method. The last time I googled about the topic, it didn't look like anyone else had had much success adding audio to the stream.

Does anyone know of any RaspberryPi projects that have succefully integrated audio into the video feed?

I set up an RPI camera without any of the echo stuff: https://blog.thekyel.com/?anchor=motion

It was fairly easy, but there were a few gotchas. It does a pretty good job, but I do get some false-positives with changes in light.

Now that I see this project, I really need to put a video together showing how mine works....

Nice hack, but the 80s called and wants to popularize a low latency analog system.

I just don't like the 6 second lag for security applications.

Slightly off-topic: Does anyone know what is state-of-the-art for small cameras suitable for surreptitious security?

Huh, I may have to look into a home wifi camera system based around Pi's. Sounds fun, and far less concerning than proprietary IoT Cameras.

This looks cool! I wish I could afford an Echo Show :)
