Sentinel Go battery-powered security fog generator by Smoke Screen
Security fog has always worked. It fills a space in seconds, eliminates visibility, and strips intruders of the one thing they rely on most — the ability to see. Used across retail, industrial, agricultural, and financial environments worldwide, it remains one of the most effective active deterrents available to security professionals today.
But one question has always limited its reach: what happens when there is no mains power?
The Sentinel Go answers that question — definitively.
And before diving into the full detail, here is what makes it different from anything else in this category: the Sentinel Go operates in three distinct power configurations — standalone battery, trickle-charged, or fully powered from a mains supply. That flexibility means one unit covers every type of site, regardless of infrastructure. More on each mode shortly.
The Problem That Has Always Held Security Fog Back
Walk into any serious security risk assessment and you will find a familiar pattern. The sites with the least electrical infrastructure are almost always the sites with the greatest exposure to theft and intrusion.
Vacant premises awaiting sale or development. Farms and agricultural outbuildings. Construction sites mid-build or between phases. Shipping containers and portable storage units. Remote compounds and isolated facilities. Locations where load shedding or power instability is a daily operational reality — a persistent challenge across South Africa and emerging markets.
These are not rare edge cases. They are a significant portion of the highest-risk locations on any security manager’s register — and for years, active fog protection simply could not reach them.
Battery-powered units existed, but the honest assessment was always the same: underpowered, limited fog density, not built for real-world conditions, not compliant to the standards that insurance and loss prevention professionals require.
That has changed.
Introducing the Sentinel Go

Smoke Screen has launched the Sentinel Go — a professional-grade, battery-powered security fog generator engineered for sites where conventional installation is not practical, and where compromise on protection is not acceptable.
This is not a scaled-down version of a standard fog system. It is a purpose-built unit that delivers the same fog performance Smoke Screen is known for — without a fused spur, without invasive electrical works, without waiting on infrastructure that may be weeks or months away.
Drop it into any high-risk space and it transforms exposed ground into a no-go zone within seconds.
Power is optional. Protection is not.
Three Operating Modes: Built for Every Site
The three-mode power architecture is the defining feature of the Sentinel Go, and the reason it serves a wider range of deployments than any previous battery security fog system.
1. Standalone Battery Operation
Fully off-grid. No external power required. Ideal for vacant premises, isolated farm buildings, construction sites, and any location with zero infrastructure. Protection is available from the moment the unit is placed and connected — no electrician, no delays.
Battery Compatibility: The Sentinel Go is compatible with LDC1214 batteries (supplied dependent on territory — please ask your supplier for local availability). This high-performance battery ensures reliable operation across diverse security environments.
2. Trickle-Charged Operation
Where a limited power supply is available — a solar panel feed, a temporary generator, a partial site supply — the Sentinel Go accepts a trickle charge, extending operational deployment time while maintaining full fog readiness. Adaptable charging supports 12–24 volts at 250mA / 1A, covering a broad range of real-world power sources.
3. Fully Powered Operation
Connected to a continuous mains supply, the Sentinel Go operates with full monitoring capability, comparable to a traditional hardwired installation. This mode is ideal for premises that want a faster, lower-cost installation without invasive electrical works — even where power is available.
One unit. Three configurations. Every site is covered.
The Technology Behind the Performance
Instantly Heated Coil
The Sentinel Go uses an instantly heated coil rather than a traditional metallic heater block. This eliminates the continuous power draw required to keep a heater block at operating temperature — a critical advantage in battery operation. When triggered, the coil reaches temperature immediately and fog deploys without any warm-up delay.
Two-Position Fog Output
By changing the baseplate and internal board orientation, the direction of fog deployment can be adjusted to suit the specific space. Corner positions, low ceilings, confined containers — the Sentinel Go adapts to the site layout, ensuring coverage across the full space with no blind spots for intruders to exploit.
3 Inputs / 6 Outputs for Alarm Integration
Full compatibility with traditional alarm systems, wireless relays, and standalone configurations. The Sentinel Go integrates cleanly with existing alarm infrastructure without requiring a bespoke installation project — a practical advantage for security systems integrators working across varied site types.
Extreme Environment Rated
Operating temperature range of -10°C to 50°C ensures reliable performance in harsh conditions — from frost-hit construction sites in midwinter to sun-exposed agricultural compounds in summer. Built for the real world, not controlled indoor environments.
Standards Compliance
EN50131:8 and IEC62642:8 compliant, with a CNPP Rating of Class I Category 30, and backed by £10 million product and public liability insurance. For specifiers who need to satisfy insurance requirements and demonstrate due diligence in site protection, compliance is non-negotiable. The Sentinel Go meets it fully.
Where the Sentinel Go Delivers: Real-World Applications
Vacant and Empty Properties
Empty properties carry a disproportionately high risk profile. Copper theft, unauthorised entry, arson — the exposure of an unoccupied building is significant. The Sentinel Go provides active remote security fog protection from day one, without waiting on electrical installation.
Construction Sites
Plant equipment, copper cabling, tools, and materials make construction sites a persistent target for organised theft. Conventional alarm systems are regularly defeated and response times are slow. Battery-powered security fog deployed at key entry points changes the risk profile of the site from the moment it is placed.
Agricultural Land and Farm Buildings
Rural crime continues to rise, with outbuildings and equipment stores targeted by organised groups conducting advance reconnaissance. The Sentinel Go delivers always-on protection for buildings that mains infrastructure has never reached.
Shipping Containers and Portable Storage
High-value goods stored in containers represent a clear target. The Sentinel Go’s compact rugged steel casing and fully battery-independent operation make it a natural fit for container security — deployable, relocatable, and fully effective.
Regions with Unstable Power Supply
Load shedding affects large parts of South Africa and emerging markets. For Smoke Screen’s international distributor network, the Sentinel Go directly addresses a market need that has gone unmet. Battery-powered security fog that remains ready regardless of grid reliability.
Fully Serviced Premises Requiring a Smarter Install
Even where mains power is available, the Sentinel Go offers a faster, less invasive installation route. No fused spur required. No electrician on site. Lower installation cost and reduced energy consumption from day one.

Future-Ready: The Sentience Platform
The Sentinel Go is built not just for today’s security demands, but for where the industry is heading. An IP upgrade is available, enabling integration with Smoke Screen’s Sentience platform — delivering remote monitoring, estate-wide management, and centralised visibility across an entire fog protection network.
For security managers and loss prevention teams overseeing multi-site portfolios, this represents a significant operational step forward. The ability to monitor, test, and manage remote security fog units across every location — including the most remote and off-grid sites — from a single platform changes what is possible at scale.
How Does It Compare?
The battery-powered security fog market is well-established, with several providers serving the South African security industry through established distribution networks. Security professionals have access to various solutions, each with different capabilities and feature sets.
However, the Sentinel Go brings a distinct approach to this category. It is engineered to British standards, carries EN50131:8 and IEC62642:8 compliance, and is backed by a 3-year warranty and £10 million product and public liability insurance. It carries the Smoke Screen reputation — over 30 years of delivering active fog protection to commercial, retail, and industrial clients across the world.
Critically, the Sentinel Go’s three operating modes, instantly heated coil technology, battery compatibility (including LDC1214 batteries where available), and compatibility with the Sentience platform give it a flexibility architecture that addresses multiple deployment scenarios within a single unit.
For installers and security specifiers evaluating off-grid security fog options, the Sentinel Go offers a combination of compliance, flexibility, and field-proven reliability that merits serious consideration.
