BSS app iconLast weekend I sat down and built a surveillance system, including an iPhone webapp, for my apartment using my old iBook, an external iSight, the Webcam Software EvoCam and a set of scripts in AppleScript, PHP and some shell scripts.

The whole thing is pretty custom made but I’ll document it here anyway and with a basic understanding of the technology it should be fairly easy to reproduce with whatever hardware you have available. At the end of the post you’ll find a ZIP file with all the scripts I used in the setup.

The set up

  • The iBook has the iSight connected and pointed at the entrance door.
  • iBook is using MAMP to serve PHP scripts and produces some audible confirmation messages.
  • The iPhone webapp shows if the system is armed or not, can start or stop EvoCam, lists all the available surveillance videos and offers a link to the live video stream.

AudiogalaxyToday I’d like to highlight a software I found out about yesterday called Audiogalaxy.
If you’re about my age you surely remember the peer-to-peer audio file sharing application by the same name that took over Napster’s market share in 2001. Well this software is actually made by the same people only that they’ve shifted their focus from file sharing to a “placeshifting service” as they call it. Audiogalaxy lets you install a small client software on your computer that scans all your music and makes it available to you on the audiogalaxy.com website, Android phones & iPhone. And it’s completely free!

There have already been a number of attempts to offer this kind of service, the one I used quite a bit was Simplify Media which unfortunately was shut down. What makes Audiogalaxy truly stand out for me is it’s easy of installation, performance and iOS integration. I’ll outline the steps necessary to get the whole system up and running on a Mac and an iPhone.

  • First go to audiogalaxy.com and click on Sign Up. The easiest way is to use Facebook connect so we’ll choose that option.
  • Next you’ll be offered to download the client application for your computer which already has your login data included, so just drop it into your Mac’s application folder, start it and you’re good to go.
  • The website patiently waits to detect the client application on your computer which then starts scanning your default Music location.
  • It can take quite a while to index a big library, so hop over to your iPhone in the meantime and download the Audiogalaxy App from the App Store.
  • Start the Audiogalaxy App on your iPhone, log in with Facebook and you’ll be instantly connected to the music on your computer including all the Playlists you’ve set up in iTunes.

From now on you’ll be able to play all your computer’s music via the website or your mobile device (an Android client is available as well). What makes this service really special is the level of integration they’ve been able to accomplish with iOS. It can really replace you iPod App on the iPhone by offering background music playing, access to play/pause/skip/volume controls via all the available shortcuts and the headset buttons. One last thing I was doubtful about was how it will perform while being on the move, so I tested it out on my morning commute today and let me say I was extremely pleased.
I started music playback before leaving my appartement, so I was still connected to my home WiFi. When I reached the street my iPhone lost contact to the WiFi and switched to 3G, this only triggered a ~2 second gap in playback, after which the music just played on from where it lost contact. Performance on 3G is absolutely brilliant and I could keep on listening during the whole train ride. What was astonishing was that there is a tunnel on my way to work where I know that there is no cellular access at all (phone calls always drop while going through that tunnel), the Audiogalaxy app apparently had enough of the music buffered, so playback continued without interruption. When I got close to my office I once again experienced a little gap in the playback, that was when my phone picked up the company WiFi.

Let me finish of by stating a few things I’d love to see improved/added to the iPhone client:

  • Submission of played tracks to Last.fm
  • Updating of the playcount in iTunes’ library
  • Gapless playback between tracks of an album. If the software manages to play through short signal losses, why not pre buffer the next track as well to offer continuous playback?

Facebook iPhone Dev Quits Project Over Apple Tyranny

What a shame! Joe Hewitt was a very skilled iPhone developer and it’s a pity to see him move back to the web because of Apple’s App Store policies.

My decision to stop iPhone development has had everything to do with Apple???s policies. I respect their right to manage their platform however they want, however I am philosophically opposed to the existence of their review process. I am very concerned that they are setting a horrible precedent for other software platforms, and soon gatekeepers will start infesting the lives of every software developer.

The web is still unrestricted and free, and so I am returning to my roots as a web developer. In the long term, I would like to be able to say that I helped to make the web the best mobile platform available, rather than being part of the transition to a world where every developer must go through a middleman to get their software in the hands of users.???

Here’s quite an interesting interview with Joe Hewitt from earlier this year at the Mobile Orchard Podcast.
