The server program of the security firm was unable to receive messages from monitored objects in a reliable manner after the number of protected objects exceeded several thousand.
Modules would send test PING messages checking the connection, but server software was unable to process the data and reflect the real situation due to a large number of incoming messages.
To find a solution that would allow securing a steady connection between the central monitoring station and modules in the secured objects without replacing too much of the equipment in operation.
A client has already had two Linux OS servers. One of them has begun to function as the main server and another as a standby server once our program Linux Ipcom was installed.
– Two servers (main and standby) with installed monitoring program for message monitoring
The security firm used two monitoring program servers. New Linux Ipcom servers transfer the data on protected objects to both monitoring program servers.
– Safe data transfer using public networks
Safe VPN (Virtual Private Network) GSM cards for operation within a closed security firm network were introduced. Thus, the server was protected from external access from public networks and only 1 MB data flow is used per module monthly.
