Smart Doorbell 889251362774 teardown

Got this doorbell on ebay for about $60AUD. I think it's pretty cool.



The build quality looks appropriate to the price. The unboxing was a nice experience, incidentally. The device is an all plastic body, with a nice exterior. The bracket shoe looks like a tough dense sort of plastic.

The device is setup and operated via an app, like other contemporary wifi cameras, no browser friendly web server. On the app store search for "xsh" (link). Setup pairing is done an audio signal, so you need to be next to it. Sharing with other devices seems to be done via a QR code, and I assume the password will be required [to be tested].

The operating experience looks solid. The app is friendly enough.

Few notes:

  • Batteries are not included, so BYO 2x 18650. There is a microUSB socket on the body, for charging I assume. The spec says a full charge should last for about 6 months. Alternatively there is a provision for wired power, but there is not voltage reference anywhere that I could find (I would start with 5V).
  • MicroSD card is not included. It is not essential to normal operation, but if you want CCTV style automatic recording then you will need to open the device (6 screws), locate the slot, and click in the card. The spec says max 32GB; I will be using 8, and not expecting much activity at all.
  • The app has a battery and WIFI signal status indicator on the live view.
  • CPU: HI3518E ARM926


Here's what I saw.
