Medical alert services assist individuals in emergencies, particularly those who may be elderly, disabled, or have medical conditions that put them at risk.
A monitored fire alarm is connected to a monitoring service or central monitoring station. When a fire alarm system detects smoke, fire, or other fire-related events, it sends a signal to the monitoring service.
There are various devices used in home security systems to detect intruders and trigger a burglar alarm, such as door and window, motion, and other hardware.
