What is Online Security System?

When you hear the term “security service,” you may think of a service in which security guards patrol offices, factories, etc. Patrols by security guards are common in Vietnam.

However, some security services include the “Online Security System,” which uses security sensors to detect abnormalities such as a burglar breaking in or a fire breaking out, and notifying a security company.

In this writing, we will introduce an overview of Online Security System.

What is Online Security System?

The Online Security System is an alarm system that installs security sensors in offices and factories in order to strengthen security and detects abnormalities such as intrusion by thieves and fire.
