How Do Security Robots Work?

Security robots are mobile and fully autonomous machines that deliver 24/7 AI-powered surveillance of your premises.

CCTV cameras are cheap, but they only capture what they’re pointed at. Fisheye lenses can expand the field of view, but then tend to lack the necessary detail, the numberplate a blurred mess as the offenders drive away.

Human security solves these issues, but at a big cost. Labour is expensive and only getting more so, particularly for afterhours shifts that also tend to bring fatigue and human error.

But there is a new option that sits neatly between these two traditional approaches to security: autonomous robots.

What are security robots?

Security robots are mobile and fully autonomous machines that deliver 24/7 AI-powered surveillance of your premises.

These wheeled robots patrol your property, using advanced sensors and AI vision to gain a complete view of the facility, then crunching that data with algorithms designed to recognise and record anomalies.

They’re capable of delivering continuous and proactive protection that dramatically outperforms CCTV and comes at a fraction of the cost of human security.

What can security robots do?

Modern security robots are incredibly capable machines packed with cutting edge tech.

Autonomous navigation

  • 3D LiDAR mapping: Security robots create a 3D map of the environment using light detection and ranging (LiDAR), then analyse that map in real time with SLAM (simultaneous localisation and mapping) algorithms.
  • Obstacle avoidance: 3D sensors and smart routing allow security robots to safely and autonomously navigate busy spaces like airports and malls, actively avoiding people, vehicles, furniture and unexpected hazards.
  • 24/7 patrolling: No shifts, no worries. Security robots work day and night, even auto-docking themselves to self-charge. Between two you can enjoy 24/7 security coverage.

AI-powered surveillance

  • Computer vision: HD cameras send visual data to AI algorithms that hunt for anomalies.
  • Targeted analytics: Security robots offer automatic number plate recognition (ANPR) and anomaly detection (flagging loitering, perimeter breaches, vandalism, forced entry).
  • Active deterrence: Built-in speakers, warning beacons and two-way audio allow remote security teams to advertise their presence, issue warnings and intervene.

Centralised monitoring and more

  • Incident escalation: The robot sends live 4K video and notifications over a secure connection to building managers and centralised security teams who can instantly take action.
  • VMS & IoT connectivity: WiFi-enabled robots stay connected wherever they roam, and can be integrated into your existing video management systems (VMSs) and smart building systems.
  • Floor care: Why stop at security? Dual-function models add floor cleaning capabilities to maximise the ROI of your investment.

Why choose a security robot for your business?

Packed with a comprehensive suite of cutting edge features, modern security robots present a compelling option for any organisation looking to enhance on-site security. When compared to security guards and CCTV, security robots offer a wealth of benefits:

  • A visible presence: Prevention is the best cure, and no deterrent is more powerful than a high tech robot wandering the halls 24/7.
  • Cost-effective: Surprisingly affordable, no wages or overtime, minimal ongoing costs; security robots are a far cheaper security solution than boots on the ground.
  • Highly capable: Robots record and upload HD video in real time, while a complex array of sensors can identify anomalies and instantly alert you to potential issues.
  • Fatigue-free: Tireless patrolling and continuous monitoring gives you a level of coverage that no human guard can match.

Ultimately an investment in security robots will deliver reduced risk, lower costs and a safer space for your team, customers and community.

The future is now

Security robots are no longer just found in sci-fi novels and Hollywood scripts – they’re securing local commercial premises as we speak. They do so with high accuracy, zero fatigue, and all while delivering significant cost savings.

But to fully appreciate this transformative technology, you really have to see it in action. That’s where we come in.
