If your building contains areas where sensitive equipment or data is stored, you may be considering added physical security to safeguard your most valuable assets. A physical access control system (PACS) could provide the protection you need.
In this blog, we explain what a PACS is, break down its key components, and offer guidance on selecting the right system for your property.
What is a Physical Access control System (PACS)?
A physical access control system is a security solution that managers who can enter and move through specific areas within your facility or workplace. In a standard office setting, traditional systems often rely on key cards or biometric scanners to grant access to buildings and restricted zones.
In the past, access to secure areas depended on security personnel who manually approved or denied entry at key locations. Today, physical security access control has become digital. Physical access control systems (PACS) now use tools like key fobs, swipe cards, and personal identification numbers (PINs) to verify authorization, replacing the need for traditional physical keys.
Modern access control systems now offer more advanced options, allowing employees and visitors to use their mobile devices as digital entry points. Rather than using a conventional sign-in process, users can scan a QR code at the entrance, which triggers the sign-in procedure on their phone, streamlining entry and saving time.
Components of Physical Access Control Systems
A physical access control system (PACS) does more than simply block entry. It combines several key components that work together to prevent unauthorized access while allowing smooth entry for those who are approved.
Here are the five main components of a PACS:
- Physical Access Barriers: To restrict entry, you need physical barriers such as locked doors, gates, or turnstiles. These require an access method like a key fob, PIN, or card.
Barriers may also be supported by authority barriers, such as security guards or staff, who check credentials and reinforce access rules.
- Identification Credentials: These credentials verify who is trying to enter. Common types include key cards, fobs, PIN codes, QR codes, and smartphones. Users present their credentials at access points to gain entry.
- Readers: Installed at entryways, readers scan credentials and pass the information to the control panel. Some readers also let visitors request access by contacting a staff member or resident.
- Control Panel: The control panel acts as the system’s brain. It checks if the scanned credentials are valid and, if approved, tells the physical barrier to unlock.
- Server: The server stores user data, access logs, and permission settings. Servers can be onsite or cloud-based. Cloud systems offer flexibility, allowing staff to update access rights remotely. Keeping servers secure and up to date is essential for maintaining protection.
In a nutshell, PACS is a complete security solution that blends hardware, software, and procedures to control who enters your property, without disrupting daily operations.
Physical Access Control Authentication Methods
Here are the most widely used methods to authenticate access in physical security systems:
Keycards and Fobs
Convenient and affordable, keycards and fobs are ideal for offices, co-working spaces, and multifamily buildings. They’re easy to issue, reprogram, or deactivate when access needs to be updated.
PIN Codes
Access codes are a simple solution that doesn’t require physical keys. Ideal for gated communities, small offices, and gyms, PINs can also be temporary, making them useful for guest access.
Biometric Scanners
Fingerprint, facial, or iris recognition offers high security and cannot be easily lost or copied. Best suited for data centers, luxury properties, and secure facilities.
Mobile Access
Smartphone-based access is contactless, secure, and allows remote management. Perfect for modern buildings and tech-savvy environments, it also supports temporary access for guests.
Vehicle Access Control
Using windshield tags, vehicle readers, or license plate recognition, vehicle access control allows hands-free entry for registered vehicles. Ideal for parking garages, gated communities, and campuses.
Video Intercoms
Video intercoms let you see and speak with visitors before granting access. Suitable for apartments and offices, they enhance security and support remote access control.
Why are physical access control systems important?
The main reason why PACS have gained so much importance is because they have revolutionized access control. It not only prevents unauthorized access but also gives operators full control over who can enter specific areas within a building. Moreover, you can customize access for each employee, ensuring that only the right people reach sensitive spaces.
PACS also helped reduce the risk of security breaches from both internal and external sources. A 2022 report showed insider threats increased by 44%, with each incident costing over $15 million. Since PACS were inducted, reports suggest a significant decrease in such incidents.
Additionally, Physical access control is also essential for meeting safety and privacy regulations, particularly in settings such as multifamily buildings, commercial offices, medical facilities, and law offices.
Physical vs. Logical Access Control
Physical and logical access control systems both manage who can access restricted areas or information. Physical access controls limit entry to spaces like buildings, rooms, or equipment, while logical access controls protect digital assets, ensuring only authorized users can access sensitive data.
Which is better you might ask? The answer is Logical Access Control. Logical access control is more secure than physical access alone because it requires identity verification, like a PIN or password, not just a key or fob. This extra step makes it harder for the wrong person to get in.
