A Central Alarm Monitoring Station (CAMS), also known as a Central Monitoring Station (CMS), is a facility that provides centralized monitoring and management of security and alarm systems. It serves as a hub where various security alarms, such as intrusion detection systems, fire alarms, and video surveillance systems, are connected and monitored by trained personnel.

The primary function of a CAMS is to receive and process alarm signals from different sources. When an alarm is triggered at a protected site, such as a residential or commercial property, the alarm signal is transmitted to the CAMS through a communication channel, typically over telephone lines, cellular networks, or the internet. The CAMS receives the signal and displays relevant information about the alarm, including the location and type of event.

Trained operators or dispatchers at the CAMS then assess the situation and take appropriate action. This can involve contacting the property owner, keyholders, or emergency services, such as the police or fire department, to respond to the alarm event. The operators may also use video surveillance systems to visually verify the alarm before taking action.

In addition to alarm monitoring, CAMS facilities often provide other services such as video surveillance monitoring, access control management, and remote system administration. They may also offer 24/7 customer support and generate reports on alarm activities and system performance for their clients.

CAMS are commonly used by security companies and service providers to offer centralized monitoring services to their customers. By centralizing the monitoring process, CAMS help ensure a prompt and coordinated response to security incidents, enhancing overall safety and protection.
