The security solution is developed by CESTEL, a major Spanish system integrator and service provider and deployed by Securitas Direct, a world leader in security systems. The initial deployment targets an installation base of 7,000 households throughout Spain. Home cameras, connected to the security system via ADSL can be accessed by 3G subscribers, who are called when a manual or automatic alarm triggers the system. The 3G subscriber may also dial-in to the system and obtain direct access to the home surveillance camera whenever desired. The cameras and other electrically controlled devices such as doors, gates and alarms can be activated by the number pad on the 3G mobile phone. Utilizing the camera's built in speaker and microphone, the solution enables 3G subscribers to verbally communicate with the actual location where the camera is set. "3G mobile access to surveillance cameras is a solution that our customers are looking for," said Mr. Jose Luis Martin, Securitas Direct's CTO. "The solution provided by RADVISION and CESTEL allows easy access to 3G video streams from any device, anywhere, in real-time and with no need for a client download, resulting in an efficient and manageable large scale deployment. The superior video quality and smooth operation enhances our surveillance and security offerings significantly." The 3G integration application, developed by CESTEL with their 3G Builder(TM) product and RADVISION's IMS ready SCOPIA(TM) Interactive Video Platform, is based on network and device-agnostic infrastructure that enables remote cameras to be accessed and operated by any 3G handset. "Our ability to quickly develop the best system to comply with Securitas Direct's forward looking requirements for the initial deployment is an excellent example of the benefits of our continued partnership with RADVISION," said Mr. Fernando Ortiz, CEO of CESTEL. "The SCOPIA Interactive Video Platform's flexible API allowed us to implement together with the CESTEL 3G Builder(TM), an advanced interactive video application for the security market, that combines 3G access to security cameras' video streams, remote control of the cameras, bidirectional audio, and access to recorded video streams. We are confident that our combined solution provides the ease of use that Securitas Direct wants their customers to enjoy." "Securitas Direct and CESTEL are pioneering new paradigms in home surveillance and security and leading the market towards widely-deployed remote interactive multimedia access. The new systems are not only technologically viable, but their ease of use and ubiquitous availability offers commercial promise and potential. The remote voice and video communications service is also appealing for personal monitoring of the elderly, nannies, babysitters, household pets and more," said Alon Barnea, General Manager of RADVISION's Mobility & Service Provider Business Unit. "This video-based home surveillance service is further testimony to the importance of advanced scalable interactive mobile video communications, combining real-time external media sources and bidirectional video, fulfilling various day to day needs that are now becoming part of the telecom landscape."
