What is the best method to provide cellular backup to a land line at your customer's camera system.
Case 1: A separate ADSL line is provided for the camera network. If the ADSL line goes down, the camera network will fail over to the Microhard modem. The automation software at the monitoring station is expecting a particular public IP address to resolve what account it is or to initiate a session with a camera. The operator may have to initiate a session while the site is in fail over.
Case 2: Instead of a separate ADSL line we use the customers network and their internet connection and setup the appropriate port forwarding.
