The Cost of a Security Robot vs. Traditional Security Staff

By Robot Center, Robots of London, and Robot Philosophy

As security becomes an ever-pressing concern for modern businesses, the question isn’t whether to invest in better security, but what type of security yields the best return on investment: human or robotic?

In this article, we’ll dive deep into the true costs—both upfront and long-term—of employing traditional security guards versus deploying advanced security robots. We’ll also explore operational benefits, real-world use cases, and how companies like yours can make a smart, cost-efficient transition.

At the end, we’ll show you how our robot consultancy and robot recruitment services can help you seamlessly implement and scale robotic security solutions tailored to your environment.

Section 1: The True Cost of Traditional Security Staff

1.1 Salary and Overtime

The average annual salary for a licensed security guard in the UK ranges from £23,000 to £32,000. Add overtime, shift premiums, holiday pay, and sickness cover, and that figure can swell to £40,000+ per guard per year.

Security is typically a 24/7 operation, which means:

At least 4 full-time staff are required to cover one location
That’s £160,000–£200,000+ annually per site

1.2 HR and Administrative Overheads

Employing staff also requires:

Recruitment fees
Background checks
Uniforms and equipment
Training and upskilling
Management and supervision

These indirect costs easily add another £10,000–£15,000 per guard per year. Not to mention insurance liabilities, union disputes, and potential turnover costs when a guard leaves.

1.3 Human Limitations

Security staff are human, and humans:

Get tired during night shifts
Miss details during long patrols
Forget protocols under pressure
Can be distracted, bribed, or overwhelmed

While highly valuable, human guards are inconsistent over time—especially when performing repetitive, observational tasks.

Section 2: The Real Cost of Security Robots

2.1 Upfront Investment

The upfront cost of a fully autonomous security robot ranges from:

£30,000 to £80,000, depending on the model and sensor suite
Plus setup, installation, and training (typically £5,000–£10,000)

This means your initial investment is between £35,000–£90,000—equivalent to the cost of hiring one security guard for 1–2 years.

But unlike a human employee, the robot:

Works 24/7 without breaks
Never calls in sick
Never needs a pay raise
Never forgets protocol

2.2 Annual Operating Costs

Charging & Maintenance: ~£1,000/year
Connectivity & Cloud Fees: ~£1,500/year
Software Upgrades & Support: ~£2,000/year

That’s just £4,500–£6,000 per year to keep your robot security guard operational.

Compare that to £40,000+ per human guard, and the ROI becomes clear within 12–18 months.

2.3 Leasing & Robot-as-a-Service (RaaS)

Want to avoid large capital expenditure? Use Robot-as-a-Service (RaaS) models instead:

Monthly lease: £1,500–£3,500/month
Includes hardware, servicing, software, and upgrades
Tax deductible as an operating expense

Robots of London offers robot rental for events, exhibitions, and trials, while Robot Center provides permanent installations and consulting on leasing terms.

Section 3: Capabilities Beyond Human

Modern security robots aren’t just mobile CCTV cameras—they offer AI-powered, multi-sensory protection that enhances your entire security operation.

3.1 Autonomous Patrols

Navigate predefined paths or randomised patrol routes
Cover large indoor/outdoor areas (up to 20,000 m²)
Record video, detect movement, and alert staff in real-time

3.2 Facial Recognition & ID Verification

Spot intruders
Detect known threats
Validate staff credentials in restricted areas

3.3 Intruder Detection & Response

Send alerts to mobile devices or control rooms
Flash lights, play warnings, or trigger alarms
Record and log every incident with time-stamped footage

3.4 Environmental Monitoring

Detect smoke, fire, gas leaks, water spills
Monitor temperature and humidity (ideal for data centers)
Sense toxic gases in industrial settings

3.5 Integration With Existing Security

Sync with CCTV, access control, and PA systems
Feed data into your SOC (Security Operations Center)
Integrate with platforms like Milestone or Genetec

Robots don’t replace humans—they enhance them. One robot can free up human guards to handle high-level decision-making, visitor interactions, or emergencies.

Section 4: Case Study – Warehouse Security in Milton Keynes

A logistics operator in Milton Keynes had:

3 guards on rotating shifts
Total annual cost: £132,000
Rising absenteeism and a warehouse break-in led them to trial a robot

They hired a security patrol robot through Robot Center on a 3-month pilot:

Cost: £2,000/month all-in
Result: Improved coverage, no incidents, data analytics for weak points

They now operate with:

1 robot + 1 human guard
Total cost: £58,000/year
A saving of £74,000 annually

They reinvested the savings into upgrading their lighting and perimeter cameras—creating a layered, data-rich security ecosystem.

Section 5: The Hidden ROI

5.1 Insurance Premiums Drop

Insurers increasingly recognise robotic surveillance as a risk mitigator. Customers using robots report:

10%–25% reduction in premiums
Faster claims processing
Better incident evidence

5.2 Safety & Compliance

Robots are non-confrontational and ensure compliance with company policy. No complaints of bias, harassment, or misconduct.

5.3 Data-Driven Security

With computer vision, analytics, and cloud storage:

Review patrol logs
Spot repeat incidents
Adjust staffing based on real-time risk heatmaps

You move from reactive to proactive security.

Section 6: Addressing Common Objections

Objection 1: “We want the human touch.”

✅ Robots don’t eliminate humans—they empower them. Free your security staff from tedious patrols and focus on human-centric tasks like:

Conflict resolution
Visitor assistance
Crisis response

Objection 2: “Too expensive to start.”

✅ RaaS models mean no upfront capital—just lease, trial, and scale as needed.
