Technical challenges of CCTV on mobile phone 
(20/09/2007)
British surveillance market is one of the most developed on the world. One of the most current issues for the CCTV market is to display live video on mobile phones, with professionalism and reliably.
There is demand for a solution which would enable users to view cameras installed at home or in office on their mobile phone. It is a solution that gives them peace of mind as they can keep an eye on their property remotely and from almost anywhere.
The challenge for manufacturers is to achive good quality of displayed video which has been previously transmited through low bandwith media like UMTS/GSM/GPRS. Currently it can be achived only by using a relevant method of compression, which is offered by manufacturers of the most advanced software. One module of software usually called Server application installed on standalone DVR or PC based DVR will exchange received signals from analog camera or coded stream of data from network camera and compress them by special method.
That special method of compression uses the difference between the current frame being processed and a previous frame of video, ensuring that information that does not change, e.g. a static background, is not repeatedly transmitted. Server application will connect with a client application installed on the mobile phone and transmit smoothly, coded by this method, a video directly to the mobile phone.
For manufacturers of software which already offer a differential image compression method or comparable methods of compression, a challenge remains: the diversity of mobile phones and versions of Operating Systems installed on them.
One of the most advanced systems offered on the market - VDR-S and Net Station by Alnet Systems - gives opportunity to view installations by mobile phones such as Nokia 40, 60, 80, 90 series or Sony Ericsson p 900 series and other mobile devices equiped with Windows Mobile or Symbian Operating Systems.
Compatibility of Symbian or Windows Mobile installed on mobile phone with Client application can be checked remotely. Client applications for phones with network connection can be downloaded for free.
