Abstract: The present invention relates to a method and a system with increased security for remote monitoring and mobile remote control of objects. The mobile system consists of at least one local system for monitoring (4), communication devices (8) for data transfer between at least one monitoring object (11) and at least one monitored object (12) and connection system (1). The connection system (1) is one private computer (2) and cellular (3) network of a mobile operator, which is capable of registering Access Point Name and has Dynamic Host Configuration Protocol (DHCP) server with capability for reservation of static IP addresses. A method is discovered where controlled devices for communication and controlling devices for communication are connected to a private computer and cellular network of a single mobile operator.
