Which technology is commonly used by alarm monitoring systems to connect to central stations in modern environments?

• A. VoIP
• B. GSM
• C. FM radio
• D. Satellite

Answer: (A)

Transmitting alarm data over IP networks to central stations is the standard in modern monitoring. VoIP-based paths use the internet to push event information, status updates, and alerts from the control panel to the central station. This approach is favored because it taps existing data networks, which lowers costs, simplifies integration with monitoring software, and supports quick, reliable two-way communication and remote management. GSM is often used as a cellular backup path when IP isn’t available, ensuring messages still get through if the primary network fails. FM radio and satellite exist for very specific, remote, or outage scenarios, but they’re less common today due to higher costs, limited bandwidth, and greater latency.
