How Does a Fiber Optic Security System Work?
Fiber optic security systems have revolutionized the way modern security systems operate. Compared to traditional security systems, fiber optics have a more efficient and faster approach to transmitting data. They are used in a variety of settings where security is a priority, including airports, banks, and government buildings. In this article, we'll cover how fiber optic security systems work, their advantages, and their limitations.
Advantages of Fiber Optic Security Systems.
1. Improved Speed and Efficiency.
Fiber optic security systems use optical fibers made of glass or plastic to transmit data. Compared to traditional copper cables, fiber optic cables transmit data at a much faster rate. Data is transmitted through pulses of light. Consequently, fiber optic cables are much more efficient because they can transmit much more data over a longer distance.
2. Better Security.
Fiber optic security systems are more secure than traditional security systems. Since the data is transmitted using light, it is almost impossible to hack into the system. In contrast, copper cables have electric signals that can be intercepted and compromised.
3. Resistance to Interference.
Fiber optic security systems are resistant to electromagnetic interference (EMI). This is important because a lot of electronic devices emit EMI which can interfere with the operation of traditional security systems. With fiber optic security systems, data transmission is not impeded by EMI, and this reduces the possibility of false alarms that could interfere with normal operations.
How Fiber Optic Security Systems Work.
Fiber optic security systems work by using fiber optic cables to transmit data. The system uses a series of cameras, motion detectors, and alarms to detect suspicious activity within a given area. The cameras capture footage which is analyzed by a computer system, and the motion detectors pick up movements that aren't detected by the cameras. If the system detects any unauthorized activity, an alarm is triggered, alerting the security personnel to respond.
Limitations of Fiber Optic Security Systems.
1. Expensive.
Fiber optic security systems are expensive compared to traditional security systems. The cost of installation is high, and the cost of maintenance is also higher than in traditional security systems. However, the cost can be justified by its improved efficiency and the level of security it provides.
2. Difficult to Install and Maintain.
Fiber optic cables are delicate and require specialized equipment during installation. If the cables are not installed professionally, they might be damaged and require frequent maintenance. Additionally, the system can be challenging to repair in case of a malfunction.
In conclusion, fiber optic security systems provide fast and efficient data transmission that traditional security systems cannot match. They are more secure and resistant to interference, making them ideal for critical installations that require high-security measures. However, fiber optic security systems are expensive to install and maintain and require specialized equipment.
