In 2025, AI has officially become the most powerful tool in the modern security arsenal. Surveillance systems that once simply recorded video footage for later review have transformed into intelligent, proactive systems capable of identifying and tracking individuals—even when wearing face masks, sunglasses, or hoodies. From home security brands like Eufy and Arlo to enterprise-grade systems used by law enforcement, artificial intelligence is changing the game. And it’s not just reading faces—it’s reading eyes, behaviour, and intent.

In this blog, we’ll explore how AI is revolutionising video security, the technology behind masked facial recognition, the power of eye-tracking and gait analysis, how Eufy and Arlo are leading the consumer wave, and why criminals now fear being caught by something as small as a doorbell camera.

1. A New Age in Video Surveillance

The global video surveillance market is projected to exceed $100 billion by 2030, and much of this surge is driven by AI integration. What once required human review of hours of blurry footage is now replaced with instant detection, real-time alerts, and automated evidence logging.

Security cameras are no longer passive—they are intelligent systems equipped with machine learning models trained to recognise human faces, body language, vehicles, number plates, and even subtle biometric traits like blinking frequency and pupil dilation.

The core difference? AI doesn’t sleep. And more importantly, AI doesn’t forget.

2. The Challenge of Face Masks — Solved

During the COVID-19 pandemic, widespread face mask use posed a major challenge for facial recognition technology. But it also forced an accelerated evolution of AI models. The question shifted from “Can we see the whole face?” to “What unique markers can we use when the face is partially obscured?”

Key advancements include:

• Iris and periocular recognition – The skin and structures around the eyes have unique biometric patterns. AI models can now extract enough distinct data from just this area to make reliable matches.
• Multimodal analysis – Modern AI doesn’t just rely on the face. It combines data from body shape, height, gait, voice tone (if available), and even clothing patterns to identify a person with high confidence.
• Heat mapping and motion prediction – Systems now use movement heatmaps and behaviour modelling to predict suspicious activity before a crime occurs.

3. Eye Recognition: The New Biometric Frontier

Eye recognition—more accurately referred to as periocular biometrics—has become one of the most fascinating areas of AI development in video surveillance. The area around the eyes, including eyelid shape, eye spacing, and brow structure, offers enough distinct features to uniquely identify individuals, even when 70% of the face is covered.

How does it work?

1. AI detects eyes first. Modern object detection models (like YOLOv7, RetinaFace, or MTCNN) isolate the eye region in real-time.
2. Feature extraction occurs. Algorithms extract unique features such as eye slant, iris hue, blink frequency, and wrinkle distribution.
3. Matching is run against databases. The AI compares these features with existing profiles, even if the database was built using full-face images.

This technology is particularly effective when integrated with night vision or infrared cameras, which can detect subtle differences in iris reflectivity.

4. Arlo and Eufy: AI at Your Front Door

Eufy Security

Anker-owned Eufy has aggressively rolled out AI features in its security line:

• Facial recognition with mask support – Eufy’s AI engine uses a neural network that can match identities based on masked and unmasked photo sets.
• Human and vehicle detection – Cameras ignore swaying trees or pets and focus only on relevant movement.
• AI sorting in the app – Users can view footage by category—person, package, vehicle, or animal—thanks to onboard AI tagging.

Most importantly, Eufy processes this AI locally on the device. No cloud upload required, reducing privacy concerns and latency.

Arlo Technologies

Arlo, one of the most popular smart camera systems worldwide, has embraced AI with its subscription-powered Arlo Secure platform:

• Smart Object Detection – Classifies events into people, vehicles, animals, and packages.
• AI-powered activity zones – You can draw specific zones where AI should focus, like your driveway or garage.
• Facial snapshots – Although Arlo doesn’t currently support full facial recognition due to regulatory hurdles, its AI takes high-resolution snapshots of faces which can be matched offline or sent to law enforcement.

5. AI That Recognises Gait and Movement

AI doesn’t stop at the face. Gait recognition—how a person walks—is becoming a powerful identifier. Even in poor lighting or with full body covering, everyone’s walk is unique. Speed, stride length, bounce, and arm movement all form a unique biometric profile.

Examples of use:

• Police agencies in the UK and China already use gait recognition to track persons of interest across large crowds.
• Retail theft prevention systems are now integrating gait AI to detect known shoplifters regardless of disguise.

6. Behavioural Prediction: Spotting Crime Before It Happens

Surveillance AI isn’t just reactive—it’s becoming proactive.

How?

• Loitering detection – If a person stays too long near a doorway or window, the system can send a warning.
• Pacing alerts – People about to commit a theft or assault often pace or fidget. AI trained on thousands of behavioural patterns can now recognise this.
• Abnormal movement detection – Someone walking against the crowd, rapidly changing direction, or exhibiting erratic movements triggers alerts.

This is where AI moves beyond recognition into intent detection—a powerful and controversial frontier.

7. Real-World Case Studies

Australia: Masked Robber Identified via Eyes

In 2023, a high-profile robbery on the Gold Coast involved three individuals wearing balaclavas. Despite no facial data, a Eufy 4K camera captured detailed periocular images. Police used AI to cross-match those with prior mugshots—confirming one match through iris mapping. Arrests followed within 48 hours.

USA: Porch Pirate Tracked Through Gait Analysis

A notorious package thief in California was finally caught after Arlo cameras captured several incidents. Despite using different clothes and face masks, his unique gait—slightly dragging his right foot—was a consistent match. The AI system flagged this anomaly and notified police.

8. Law Enforcement and AI: Partners in Real-Time Justice

Police and security agencies are now routinely integrating AI surveillance systems with their operations:

• Real-time suspect alerts – AI can push alerts to police mobile devices when a known suspect enters a certain area.
• Cross-database matching – AI matches suspects not just with facial images, but tattoos, scars, body dimensions, and even clothing brands.
• Geo-fencing and temporal analysis – Systems can track where and when a suspect has been seen, creating a timeline of movement to aid investigations.

9. AI Privacy vs AI Safety

The rise of AI surveillance has sparked ethical and legal debates. Privacy advocates argue that AI recognition, especially without consent, breaches civil liberties.

However, the industry is adapting:

• On-device processing – Brands like Eufy avoid the cloud entirely, keeping sensitive footage local.
• Opt-in systems – Some systems only activate advanced AI features if users enable them.
• Audit trails – Advanced systems log all AI decisions, allowing human oversight and transparency.

Digital One Agency advises any organisation using AI-powered surveillance to comply with regional privacy laws, use consent-based systems, and publish clear data policies.

10. What the Future Holds: Hyper-Personal Surveillance

Looking ahead, we’re likely to see:

• Emotion detection – AI will read micro-expressions and voice tone to flag aggression or fear.
• Multi-camera tracking – AI can track a suspect across multiple devices, even across different brands.
• Decentralised AI edge computing – Cameras will become smarter with their own local AI chips, allowing faster decision-making without internet.

And eventually, full biometric fusion—using voice, gait, iris, face, and even heartbeat patterns to create an unbreakable identification profile.

11. Why Criminals Are Losing the Advantage

Gone are the days when a ski mask or cap could protect a criminal’s identity. In the age of AI, security cameras are more like digital detectives—meticulous, objective, and tireless.

The combination of masked facial recognition, eye biometrics, and behavioural AI means that even the most careful criminals are leaving behind digital trails.

And it’s not just big institutions—you can now have this level of protection at your front door.
