A ship security alert system is a system that monitors the ship for any potential threats to its security. The system is usually composed of sensors, monitoring devices, and other equipment that can detect any potential danger. The sensors are usually placed in the different parts of the ship such as the deck, engine room, and cargo bay. These sensors are capable of detecting any movement or change in the environment which could be a threat to the safety of the ship. The monitoring device is used to keep track of what is happening with each sensor at all times. It will also send out alerts if a sensor detects anything dangerous or unusual. The equipment that makes up this type of system includes things like cameras or alarms which can be activated when necessary.
