This thing is awesome. Think cheap machine vision experiments, doorbells, baby monitors, time-lapse, home security. 1080p, wireless, with sound and more.

The hardware is a small cube, here on the shelf:

The iOS app is good, here’s a screenshot:

And it saves to device with a click:

Pros

Night vision works pretty well with four 0.5W IR LEDs. And you can even use it as a webcam/intercom or baby cam. And an SD card to record.

It can trigger based on motion and send push notifications but I’ve yet to try that.

Drawbacks

Limited to about 10 fps.

Needs WiFi and power.

No Ethernet.

Frequently out of stock on Amazon.

But damn, at $30 who cares? Head on over to Amazon and buy one to try.
