Strengths and Weaknesses of Online Monitoring System and Security Cameras

When you want to take security measures, what measures come to mind? Many people may think of security cameras. In addition to security cameras, there are various other types of security measures, such as stationed security guards and access control, but there is also an “Online Monitoring System”. By installing sensors, guards are dispatched to the premises in the event of an abnormality. Both security cameras and Online Monitoring Systems have their strengths and weaknesses. In this column, we will look at the strengths and weaknesses of both Online Monitoring Systems and security cameras.

What is an Online Monitoring System?

Online Monitoring System is a crime prevention system in which sensors are installed in offices and factories, and when an abnormality such as a suspicious person trespassing or a fire is detected, a security guard rushes to the site to confirm safety.

We will respond as follows.

① When the sensor detects an abnormality such as a burglary or fire, an alarm signal is sent to the control center, which is monitored 24/7/365.

②If necessary, the monitoring staff will contact the customer to report an emergency, and the customer can also call the police or fire department.

③ At the same time, the monitoring staff will contact the security guards deployed on-site or on standby at the base, requesting them to check the site.

④ Security guards rush to the site and check the safety and situation of the site.

The Role of Security Cameras

 What role do security cameras play as a security measure? The important role of a security camera is to record footage. In the event of a robbery, burglary, fire, internal fraud, etc., footage can be evidence and help to determine the cause of the damage. In addition, the installation of security cameras can deter illegal deeds.

Weaknesses of Security Cameras

As we have seen previously, while security cameras are a very effective security measure, they have no way of doing anything when a crime is being committed. There may be cases where security guards stationed at the facility are constantly watching the security camera footage and responding to any abnormalities, but basically, the main role of a security camera is to check the camera footage after a crime has been committed. It is also difficult to take countermeasures when a crime is committed on the premise that it will be caught on a security camera.

Advantages of Online Monitoring System

With the Online Monitoring System, in the event of an actual break-in, an alarm will go off at the site and a security guard will rush to the scene. If the security guards know that they are coming to the scene, the suspicious person may escape before completing the crime. In other words, an Online Monitoring System can prevent the spread of damage at your facility. In addition, the security company can inform the customer of the situation and, if necessary, notify the police or fire department.


Online Monitoring Systems and security cameras have their advantages. By using each product according to your needs, you can effectively improve the security level of your facility. Online Monitoring System is a common security measure in Japan and is installed in many offices, buildings, warehouses, and factories. Although the Online Monitoring System is not yet widely recognized in Vietnam, it is a recommended security measure for those who are dissatisfied with the weak points of security cameras or who want to enhance security. With labor costs set to rise further in the future, the price is reasonable compared to having stationed security guards.
