Has security technology replaced human security guards?

From AI-powered cameras to biometric authentication, security technology is more advanced than ever—and it’s being used across the globe. In fact, one report found that at least 75 of 176 countries are using AI technology for surveillance purposes.  

There is even technology that allows facilities to send robots to conduct surveillance or patrol critical areas. In 2023, New York City tested out a 400-pound fully autonomous robot in Times Square to help with law enforcement. 

Do all the advances in security technology mean manned guarding is not adding value anymore? Let’s explore how technology enhances security plans and why it may be tempting to rely solely on it to protect your people and assets. We’ll then highlight why manned guarding remains a vital part of any security operation and how combining their expertise with advanced technology creates the ideal foundation for a successful protection strategy. 

How technology enhances security management

As technology progresses, security solutions grow more sophisticated. Before AI, security cameras were only as good as the person monitoring them. With AI surveillance, large data sets can be analyzed quickly, abnormal activity can be flagged, and threats can be detected faster and with more accuracy than ever before.  

Also, instead of traditional key and lock systems, smart access controls such as biometrics, PIN codes and mobile apps use a digital approach to managing entry points. Remote monitoring, predictive analytics and robotics are additional security technologies that are improving accuracy, response times and coverage. Yet, even with these advancements, having a human guard present remains essential to assess the situation and take action when a potential threat is detected. 

Automation is appealing to businesses for many reasons

Layering advanced technology into your security program, while an investment to start, becomes more cost effective over time. AI-driven threat detection puts the focus on prevention versus reaction, while automation reduces manpower—both of which can save money and improve efficiency.  

Also, unlike people, technology operates nonstop without fatigue, providing continuous, unwavering protection. Plus, these advanced systems can gather data and create insights that can lead to proactive security measures.  

However, while technology offers many advantages, it can’t handle every situation—making the human component as essential as ever for interpreting, responding and adapting in real time. 

The limitations of relying on technology alone

While the right technology can be a valuable part of your security program, it cannot do everything. For example, false alarms triggered by faulty sensors or system glitches often require human verification to prevent unnecessary (and costly) responses.  

Additionally, power outages or technical failures can leave systems inoperable. These are just two common reasons why having on-site security personnel is essential. 

Four factors that make manned guarding crucial to a security program 

1. The deterrent effect of manned guards on crime prevention

It may seem obvious, but manned guarding is one of the most effective deterrents to crime, as the mere presence of guards can discourage criminals. A 2020 study found that property crime decreased by 31% in areas patrolled by marked police cars compared to those where normal activity continued.  

The phenomenon of being watched influences behavior—studies show that people tend to act more altruistically and display less antisocial behavior when observed, making criminals and trespassers more likely to rethink their actions when a guard is present. 

2. The possibility of immediate response and conflict resolution

In addition to acting as a physical deterrent, security guards can intercept flagged issues in real time, de-escalate conflicts before they become serious events, and handle complicated scenarios.  

Surveillance can detect a threat, but if there are guards on site, they can address the issue immediately, versus only having cameras record the incident.  

3. Making judgment calls in complex situations

AI surveillance and automation are incredibly powerful tools, but not all situations are black and white, and having a human who can accurately interpret real-world complexity is critical. For example, a fire alarm will alert emergency services, but an on-site guard can help with immediate evacuation.  

Similarly, while AI might detect a person loitering, a guard can assess whether it’s a legitimate concern or simply someone waiting for a ride, making a judgment call based on context. 

4. The human factor can go a long way

Security goes beyond just reacting to threats; it’s about creating a calm, welcoming environment. A compassionate human presence can help de-escalate tense situations and make everyone feel safer. Unlike technology, a security officer can engage directly with employees, customers and visitors. In healthcare settings, for instance, their presence can ease anxious patients.  

Whether offering directions or simply fostering a calm atmosphere, asecurity officer can play a vital role in enhancing both security and creating a comfortable environment in any setting. 

A powerful combination: manned guarding and security technology

Both manned guarding and technology offer unique benefits on their own, but when combined effectively by an experienced security provider, they deliver the most powerful results.  

The goal is achieving the right balance, as the ideal solution can vary depending on the specific situation. In many cases, technology is a force multiplier that enhances the capabilities of guards by automating monitoring and data analysis, while having a human presence provides context, judgment and quick response when needed. 

The importance of guard training for rock-solid security

Hiring highly trained guards who have undergone extensive training, and ensuring they’re armed with industry-specific knowledge, is crucial for keeping your property and site secure. Whether it’s a hospital or construction site, the combination of manned guarding with the most advanced security technology is the most effective way to achieve top-tier protection. 

Achieving the right combination of people and technology for the protection you need

Surveillance technology is a critical tool for most large companies and organizations and will continue to play an important role in security programs, but it’s not a substitute for human judgment, adaptability, and the power of a physical presence. Striking the right balance between advanced technology and highly trained guards creates the most comprehensive solution, offering benefits such as improved safety, reduced operational costs, enhanced coverage and increased efficiency.
