A collaborative alarm monitoring system (100) includes a security system host server (106) and a chat session server (116). The security host server is in signal communication with at least one security panel (102A, 102B) to receive an alert signal in response to a detected alarm event. The chat session server is in signal communication with the security system host server and is configured to store a chat session protocol and software that when executed by a hardware processor executes a chat session. A monitoring device (110A, 110B, 110C) alerts an operator of the alarm event in response to receiving the alert signal. The monitoring device includes a chat session client that generates a chat session interface to display an alarm event thread indicative of the alarm event. The chat session server generates a communication stream for each alarm event, and the communication stream is individually displayed on the chat session interface of the monitoring device.
