The real risks Security Services & Mobile Patrols lone workers face

Security Services & Mobile Patrols staff regularly work alone — in the community, on client sites, or out of hours. These are the hazards your lone working policy must address.

Intruder Confrontation

Facing trespassers or criminals during night-time site patrols or alarm responses.

Physical assault is a leading risk for SIA-licensed lone workers.

High-Conflict Zones

Working in retail, night-time venues, or hospitals where aggression is common.

Security staff face significantly higher rates of violence than the average worker.

Isolation and Injury

Sustaining an injury on a large industrial site without immediate backup or witness.

BS 7984-3, the code of practice for mobile patrol services, expects verified monitoring of patrol officers.

Your legal duty

SIA Licensing & Martyn's Law

SIA licensing standards mandate that security staff have effective communication and emergency response tools. Martyn's Law (the Terrorism (Protection of Premises) Act 2025) received Royal Assent in April 2025 but isn't yet in force, full enforcement is expected around 2027, and its duties fall on those responsible for premises and events, not on security staffing companies directly. Even so, the emergency communication and incident evidence your teams generate is exactly what your venue clients will need to demonstrate preparedness once the Act takes effect.

Built for the way Security Services & Mobile Patrols teams work

The whole platform deploys on the smartphones your Security Services & Mobile Patrols staff already carry — no devices to buy, charge, or replace.

One-touch panic alarm

Instant SOS with live location sent to your control room or mobile supervisor.

Automatic video capture

Camera triggers on alarm for cloud-stored, secure evidence for the audit trail.

Private incident reporting

Whistleblowing-compliant channel for reporting security breaches.

The complete platform

Every plan includes the full Sentry feature set

The same two-sided system — staff app plus manager portal — protects your Security Services & Mobile Patrols teams. No hardware, no IT integration, live in under an hour.

Home-screen widget SOS

Exclusive to The Sentry: fire the alarm, share your location, and start recording straight from a home-screen widget — one touch, without opening the app. In a real emergency, the extra steps simply aren’t there.

Loud or silent panic alarm

One alarm, two modes. Loud mode sounds an audible siren; silent mode is completely discreet for confrontational situations. Both instantly share live location with your managers and Nearby Team.

Automatic video capture

Recording starts the moment an alarm triggers. Unalterable footage is saved to the cloud audit trail, emailed as a view/download link, and kept on the handset. (Loud mode records video only; silent mode also captures audio.)

Lone Worker Timer

Session-based timed check-ins: set your own interval and the app prompts you to check in during a session. If a check-in is missed, help is escalated. Added specifically for the wider lone worker sector.

Fake phone call

Defuse a tense situation with a simulated incoming call that uses your phone’s native ringtone and generates a fresh caller number each time — so it appears entirely genuine.

Live location sharing (user-led)

Real-time GPS — but only during a work session you choose to start. The Sentry never tracks passively or automatically, so your personal time stays private. Privacy by design.

Private incident reporting

A confidential, whistleblowing-aligned channel to report harassment — with the option to submit anonymously. Once sent, no trace is left on the device: no email confirmation, nothing stored locally. Satisfies EHRC Step 4.

Friends & Family licences

Every staff member gets three free personal licences, so their family can use the same safety technology — entirely separate from the employer’s account.

Manager portal — included on every account

  • Live dashboard of all active team sessions — worldwide map, unlimited users visible
  • Configurable incident-report routing per user or branch, with read-receipt tracking
  • Complete encrypted audit trail with unlimited history, plus PDF export of incident reports
  • ERA 2025 compliance documentation pack and downloadable, timestamped audit trails
  • Multi-branch / multi-site structuring on one account, and unlimited manager accounts
