Abstract: A mobile security monitoring method and system and an alarm security node in the system for intelligent security system, where said intelligent security system is activated by a breach in a security zone. This breach will start a video monitoring/recording sequence that is sent out via the broadband to an alarm center. The alarm center forwards this alarm information to a user as SMS/MMS information through a mobile network. The user can view and evaluate what is going on at the security zone and can decide what action to initiate. This will minimize a false alarm generation and thus cut down the costs of follow thru of the false alarm (s) by i.e. an alarm security provider. For security and cost reason, the intelligent security system is the only client of the server-side alarm center. The concept is to use existing IT infrastructure at the security zone for user like W-LAN, broadband, GPRS and mobile devices.
