How does my camera automatically connect to the WiFi?












2















I just bought a cheap WiFi camera called SriCam SP009 (just to test it). To set it up you have to install an app on your phone. In this app you enter the WiFi password and an ID number for the camera. Then automatically the camera connects to your WiFi. My question is: How is this possible?



What I do know:




  1. I did a packet capture and there are UDP packets from the app to Chinese IP addresses.

  2. It did not work on my openWRT router. But it does work on a standard tp-link

  3. I can’t see it setting up any wlan of it’s one. Like for example the chromecast.

    A simple implementation would be 1- get wlan credentials from the user via app(already done) 2- connect to the camera's preconfigured ad-hoc network 3- set up the camera 4- reset.

  • So you think the phone connects to the adhoc network? I did not think android could do that. And that should not be stopped by me having a openWRT router.

    For android, AOSP doesn't support ad-hoc but OEMs and modified distros like CM do. I don't know if iOS does. Also same method can be used via wi-fi direct.

  • Does it happen to have bluetooth?

  • It could be using wifi direct. A lot of wifi speaker use this for their setup process.

I figured it out :) It's using something called "smart connection" by mediatek. You can find a tutorial for it here https://docs.labs.mediatek.com/resource/mt7687-mt7697/en/tutorials/digital-clock-part-2
