Virtual Receiver

The Virtual Receiver is the heart of our alarm monitoring and camera recording software components. It listens on a pre-selected IP address and port number for incoming alarm signals and regular heartbeats from remote adapters.

When an event is triggered on an alarm panel connected to an IP Alarms signalling device, the signal will be detected by the Virtual Receiver software.

Signal Handling

A quick analysis of the signal will determine whether or not a kiss-off response should be sent back to the calling IP device and alarm panel.

If the signal is good, it will be written to the IP Suite database for safe keeping and a kiss-off response will be sent back to the IP device and alarm panel. If the signal is not good, or it is a duplicate it will be ignored and a message will be written into the system log on the server.

The Virtual Receiver also receives heartbeats from remote adapters and writes them to the IP Suite database, which is constantly checked by the Heartbeat Engine for line supervision purposes. Responses are sent back to the remote adapters so that they know whether or not the server is available.

When a Linksys device receives a valid response to its heartbeats, it displays as Registered on the Info tab in the device web interface. This provides a client side visual indication that there is good communication with the server. It also confirms that the Virtual Receiver is able to traverse NAT in the client side router and that port forwarding will not be required in order for the alarm panel to successfully receive kiss-offs.

The Virtual Receiver is able to detect and log whether or not a kiss-off successfully reached the alarm panel as the Linksys client device sends an acknowledgement of the kiss-off to the server.
