What is one common method to enhance maritime security?

Installing surveillance systems is a common method to enhance maritime security because it allows for real-time monitoring and identification of potential threats in and around maritime facilities or vessels. These systems can include cameras, motion detectors, and other technologies that help in detecting unauthorized access, suspicious behavior, or other security breaches early on.

Incorporating surveillance not only acts as a deterrent against potential intruders but also provides valuable information for incident response and investigation. When coupled with immediate communication protocols, it enhances situational awareness among security personnel and creates a safer maritime environment.

Other methods mentioned, while they contribute to security in various ways, do not offer the same level of proactive monitoring and situational awareness that surveillance systems provide.
