Dear folks

A second blog post about HomeCam is up: https://yoursunny.com/t/2017/
This post describes how HomeCam registers a prefix on NDN testbed, i.e.
remote prefix registration from a browser.

HomeCam's wishlist:

   - More testbed routers support WebSockets over TLS.
   - NDN-FCH service suggests nearby routers with TLS WebSockets listener.
   - NDN-JS queries NDN-FCH service to decide which router to connect.
   - Readvertise is more robust.

Yours, Junxiao

> Dear folks
> I want to introduce a side project I've been working on since 2014:
> HomeCam, a browser-based home surveillance camera.
> This is a web application that allows you to turn an old laptop or
> smartphone into a home surveillance camera, and watch live images from the
> camera from anywhere.
> This app is built on modern HTML technologies such as MediaDevices and
> Data URIs, and uses NDN for underlying communication.
> Compared to IP-based solution, using NDN provides scalability because the
> camera app only needs to send each picture once even if there are multiple
> viewers.

> Thanks to John DeHart who helped setting up TLS WebSockets endpoints on
> testbed routers, which make the app work more efficiently.
> Thanks to those who looked at and gave suggestions to early prototypes of
> this project at NDN retreat 2014/2016 and NDNcomm 2015.
> Yours, Junxiao
