Please suggest at least three different types of physical security hardware devices and why those particular devices would be relevant in business networks today.

I have learned not all threats come from the internet. Sometimes our biggest risk is someone physically accessing a system and or the equipment.
One type of physical security hardware is access control systems, such as a key card or badge readers. These two devices help control who can enter certain areas (i.e server rooms or data centers). This is important because if someone can physically reach a server or networking equipment, they could unplug devices, steal hardware, or connect unauthorized equipment to the network. Having badge access helps limit who can move into restricted areas. Another type of physical security hardware is security cameras. I actually see the value of this in my life now because I have a Ring camera here at home, and it gives me awareness of who is coming and going around my property. In my work environment, cameras serve a similar purpose but on a larger scale. They allow my company to monitor every entrance, hallway, and other sensitive areas. Cameras can discourage theft and or unauthorized access, and they also provide recorded footage that can be reviewed if something out of the normal were to occur.
A third type of physical security hardware is biometric scanners, such as fingerprint or facial recognition systems. These devices provide stronger authentication because our fingerprints or faces cannot be easily shared or duplicated. Many businesses like the tech firm I work for, uses biometrics to protect high security areas like our server rooms and other areas where sensitive information may be stored.

Physical security hardware devices play an important role in protecting business networks and sensitive information. One common device is surveillance cameras. These are relevant because they help monitor buildings, deter theft, and provide evidence if a security incident occurs. Cameras also help businesses keep an eye on restricted areas such as server rooms and data centers.

Another important device is access control systems, such as key card or biometric readers. These devices limit who can enter certain areas, ensuring that only authorized employees can access critical network equipment. This helps prevent insider threats and unauthorized physical access that could lead to data breaches.

A third type of physical security device is motion sensors and alarms. These are useful for detecting unauthorized movement, especially after business hours. When triggered, they can alert security personnel or automatically notify law enforcement.

Together, these physical security devices help protect network infrastructure by preventing unauthorized access, supporting monitoring efforts, and strengthening overall business security.
