The threat landscape is in constant flux, driving the security sector to develop innovative and robust solutions to combat the new and evolving dangers that lie ahead.

Key facts and figures:

  • The global security market was valued at USD 143.07 billion in 2022 and is projected to grow at a Compound Annual Growth Rate (CAGR) of 8.3%, reaching approximately USD 317.57 billion by 2032
  • North America dominates the space, accounting for about 33% of global revenue
  • The video surveillance segment holds the largest market share (around 46%)
  • AI is a perfect complement for analyzing all that video; the AI Video Analytics Market is estimated to reach USD 24.09 billion in 2024 and USD 100.22 billion by 2029, growing at a CAGR of 33% year over year

AI and computer vision have been introduced to bolster security systems with great success. Thanks to these technological advancements, security providers can now accurately and efficiently spot and handle threats, keep places safe, and run operations smoothly. Whether augmenting CCTV cameras, security checkpoints, or search and rescue efforts, computer vision fits nicely into the security industry, spotting threats and thwarting potential crimes through powerful detection and recognition techniques.

Before diving into various popular applications of computer vision-based AI technologies in security, it’s important to highlight the industry’s key challenges.

Key Industry Challenges in Safety & Security

  • Compliance and Regulation: Strict data privacy rules and regulations rightfully increase the safety threshold for AI in deployments, slowing the industry’s adoption of state-of-the-art AI models.
  • False Alarms: As more security systems are being put in place, false alarms are proving to be costly while also negatively impacting operations, reputation, and overall effectiveness. 
  • Filtering Through the Noise: CCTV camera adoption is at an all-time high, with cities in Asia reaching millions of cameras per city, increasing the struggle to pinpoint and extract meaningful data amidst the vast ocean of footage that is recorded.
  • Protecting Systems Against Attackers: As the security industry advances, so do hackers and bad actors, making it paramount for deployed systems to have the best defenses
  • Ongoing Maintenance & Upgrades: Although security systems are robust, they also require regular maintenance and upgrades. For example, analog and IP cameras can last 5-10 years, however, NVR and DVR systems have a lifespan of 3-5 years.

One of the fundamental capabilities of any security system is to identify when an intruder is attempting to break in. Computer vision techniques like object detection and tracking sit at the core of AI-powered security systems, making it possible to extract key insights from massive amounts of data and to work across multiple data modalities, such as thermal and LIDAR. For example, computer vision models can be used to identify potential trespassers and track them across multiple cameras while reducing false alarms through the ever-growing robustness and dependability of the models. 

Vision-based security systems bring various benefits to commercial and residential users, including crime deterrence, 24/7 video recording to collect evidence of criminal and non-criminal events, and an overall enhanced sense of safety. In addition, the automation enabled by security systems frees up valuable staff time, allowing security teams to focus on other value-added tasks and continue to improve the overall safety of the premises.

The combination of computer vision and cameras also paves the way for new applications, including smart pet cameras, AI baby monitors, AI-powered drones, and video doorbells.

When disaster strikes, quick and efficient rescue responses are paramount. With advancements in robotics and computer vision, new rescue robots are being deployed across the globe to help respond to wildfires, earthquakes, tsunamis, and other catastrophes. 

By utilizing these robots in situations where it’s too dangerous or challenging for humans to intervene, first responders can be effective in search operations while being kept out of harm’s way. Computer vision models such as YOLOv8 and EfficientDet are frequently used due to their high accuracy and quick speed. LiDAR and RADAR are used to look for life preservers or other emergency markers in the toughest environments.

Security Checkpoint Screening

PIDRay Dataset Samples

Almost everyone is intimately familiar with the airport security screening process. However, you might not realize the significant integration of computer vision technology in this process over recent years. Cutting-edge object detection methods now play a crucial role in identifying hazardous materials using various types of X-ray scans to help ensure the safety and protection of travelers.

X-ray can be a challenging medium to work with in computer vision due to its “not quite an image” qualities. Complex systems and file formats also make it difficult to integrate quickly into these systems. Luckily, vision models have never been easier to incorporate, and what once seemed like large gaps across modalities exist no longer. Airports are deploying the latest screening machines equipped with CV to combat prohibited items, such as guns, knives, and scissors, automatically.

Facial recognition plays a crucial role in safeguarding our devices by protecting private information and serving as an effective deterrent against device theft. It is incredibly powerful and has even been able to distinguish between identical twins for years!

Beyond its role in phone security, facial recognition has applications in broader contexts. It is implemented to secure physical premises and assists law enforcement agencies in tracking criminals across multiple surveillance cameras in densely populated areas. Moreover, recent advancements have made it possible to deploy facial recognition in challenging environments, such as CCTV, with great success.

Safety takes various forms, and one critical aspect is the use of Personal Protection Equipment (PPE) at construction sites and other hazardous workplaces. Upholding safety regulations and best practices on-site is paramount, yet workers may inadvertently find themselves in areas lacking the necessary protective gear. That’s where computer vision comes to the rescue!

Hard hats, safety glasses, and masks are just some forms of PPE that can be detected using leading object detection models deployed to even the smallest IoT devices. Automated PPE detection prevents workers from entering areas with no or improperly worn PPE equipment, reducing injuries and increasing workplace safety. Some sites even implement fencing, a form of computer vision that sets off an alarm if someone enters a specific location in a camera that is prohibited. 

Here is some further reading on PPE detection with computer vision:

MIDL Technology

An intelligence platform that provides overwatch for public safety teams. Image source: MIDL

MIDL was developed to solve the problem of security cameras seeing, but not remembering – causing public safety teams to lack awareness of what threats may be at the property and waste countless hours manually searching footage. Their intelligence platform solves this problem by remembering what your existing cameras see and integrating this knowledge with other technologies at your property such as access control, sensors, shuttle buses, etc. If you are looking for something in your footage, just come and ask their software. If you want to be alerted for something, MIDL will remember everything you are looking for and let you know if the event happens.

In summary:

  • Instantly find what you’re looking for in your camera footage
  • Set very granular alerts for activity of interest
  • Save significant time and limit damages from incidents
