Facet - a Java based mobile phone software that turns any standard mobile phone into smart networked camera which can then be linked together to construed a intelligent surveillance network, will soon be available as open source code. The researchers managed to link four CMOS camera phone via Bluetooth and intelligently exchanging the captured data for simple image analysis, such as object distance and movement direction. In addition of exchanging events via Bluetooth, each camera also been programmed to send events to a central server via GPRS for comprehensive analysis. Click here for more details.
Nokia 6630 was used in the testing due to the limited image size and computing power, more complex image processing (concuretn object count and object detection restricted to moving speed) tasks can not be carried out. Surely with the advancement of the technology, more complex data can be processed on the phone as well as using a mobile phone as a realtime surveillance camera through high speed HSUPA 3G (up load video upto 5.8Mbps) link. Check on this 3G phone on a chip recently announced by Broadcom, a breakthrough all-in-one 3G chip, support HSUPA 3G broadband that allow downloading/uploading speed of 7.2Mb/5.8M. The 5.8Mb unploading speed (compare to the 384kb upload on current 3G network) will means that the modem (on chip) will be ideal to use in IP CCTV surveillance mobile gateway, where uploading speed is crucial for realtime monitoring and remote archive of high quality pictures. Perhaps we will soon see CCTV manufacturer come out with a all-in-on mobile DVR phone.
