VIO App uses your Phone’s Camera for Motion Detection

VIO, by Vesperial, is a new motion detection app which uses the primary camera of any phone running on Windows Mobile 5.0 or later to detect movement in a should-be stationary location. It can be set to run while the owner is away from home, sending a .jpg of the moment in which movement is detected in an email to any given address, and sending an SMS alert, in the case of the sensor being triggered.

VIO uses the phone’s camera to capture and detect any motion.

Motion will be detected by comparing the actual picture with one reference picture that will be automatically refreshed (settings allow you to specify when it must be refreshed)

Two ways of comparison are available :

Squares
Easy way and really fast ; the picture will be cut to squares, you just need to specify square’s width + squares sensibility + minimum squares needed to trigger an alert

Edges
More accurate but slower ; the difference between actual picture and reference picture will give us some zones, these zones will be extracted one by one, if one contains the minimum pixels needed you set then it will trigger an alert.

When motion is detected VIO will :

  • save picture as .jpg
  • send mails containing pictures to the email address you defined.
  • send sms to alert you anywhere

Continue on to the application thread.

ben_duder is an editor on XDA-Developers, the largest community for Android users. Hi! My name's Ben, and I'm proud to be one of the news writers at xda-developers. I live near London and have spent the last ten years wasting all the money I get my hands on on new gadgets with which to fulfil my technolust. I first got into HTC phones when I found a Lobster 700TV (the HTC Monet) at a very good price, and I'm ashamed to say that I couldn't have cared less about what operating system the phone was running as long as I could watch The Simpsons on the bus. As fellow Monet owners might know, the 'TV' part of the phone's alternate title was somewhat deceiving and was completely abandoned by the service providers in England. However, by then I had already fallen in love with the freedom Windows Mobile had given me. After the Monet came a Universal, with a Touch Pro following that. I've just bought a G1 (yeah, I know, get with the times!) because I'm really interested in Android as a budding operating system and don't think I could ever cope with a 'dumbphone' now that I know what's on offer. Although I haven't contributed much to the site in terms of programming or cooking help, I hope that I can give a bit back by letting you guys know what's new through my articles. If you have any questions, suggestions or complaints about those articles, feel free to get in touch with me via PM using the URL above.
