Active Intrusion Protection
Security Fog Cannons for High-Value Homes and Properties
Active intrusion protection for the moments after entry.
A traditional security system can detect an intrusion. Cameras can record it. Monitoring can escalate the response.
But in the first few minutes of a break-in, an intruder may still have time to move through the property, locate valuables, and cause damage.
A security fog cannon changes that equation. When an intrusion is confirmed, a professionally installed fog cannon can rapidly fill the protected area with dense security fog, dramatically reducing visibility and leaving an intruder unable to see, search, or continue the theft.
CastleOak designs and installs security fog solutions for homes and properties that require a stronger final layer of protection.
See security fog in action
In a confirmed intrusion, the objective is not only to alert the homeowner. It is to change the conditions inside the protected space.
This short demonstration shows how rapidly a PROTECT fog cannon can fill a residential room with an impenetrable wall of white, cutting visibility to near zero within seconds.

Stop intruders from seeing what they came for
Most break-ins are time-sensitive. Intruders want to get in, find what they came for, and leave quickly. Security fog is designed to interrupt that process.
Once activated, the fog cannon releases a dense, white security fog into the protected area. The goal is simple: deny visibility, disrupt movement, and take away the intruder's ability to locate valuables or move through the property.
This is not a replacement for alarms, cameras, or professional monitoring. It is an active protective layer that works alongside them.
Why alarms alone may not be enough
A well-designed alarm system is essential. It detects the intrusion, alerts the property owner, and can trigger a monitoring response. But an alarm does not physically stop someone from moving through the space.
Cameras provide visibility and evidence. Monitoring helps coordinate response. Sirens create pressure. But during the critical first moments, a determined intruder may still be able to act.
Security fog adds a different type of protection. It helps remove the intruder's ability to see, search, and continue. Instead of simply documenting the event, it actively changes the conditions inside the protected space.
How security fog works
Intrusion is detected
The fog system is integrated with the alarm design and trigger logic. Activation is based on a carefully planned event, not a random motion signal or casual sensor trip.
The fog cannon activates
When the designed activation conditions are met, the fog cannon floods the protected area with security fog.
Visibility is reduced within seconds
The space rapidly becomes difficult to navigate. Intruders can no longer easily identify valuables, rooms, safes, vehicles, inventory, or equipment.
The theft is interrupted
The objective is to force abandonment, reduce time on site, and limit loss before responders arrive.
A final protective layer for high-value spaces
Security fog is especially useful where valuables are concentrated, access points are vulnerable, or response time alone is not enough.
Entry points and foyers
For covering the most likely points of forced entry, where fog can stop an intrusion in the first seconds, before the rest of the home is reachable.
Luxury homes
For properties with high-value contents, art, jewelry, watches, electronics, safes, or private collections.
Garages and vehicle areas
For garages containing vehicles, tools, bikes, sporting equipment, golf clubs, tires, or seasonal equipment.
Jewelry, safes, and storage rooms
For targeted areas where valuables are stored and where rapid visibility denial can make a major difference.
Secondary homes and cottages
For properties that may sit vacant for extended periods, where the owner is not nearby to respond immediately.
Home offices, studios, and workshops
For the homeowner whose property also holds their livelihood: business equipment, servers, computers, documents, instruments, specialized tools, or a private workshop or gallery.
Technology Partner
CastleOak installs PROTECT security fog technology
CastleOak has chosen PROTECT Global as its technology partner for security fog installations.
PROTECT is a dedicated security fog manufacturer with a global presence and a deep focus on fog cannon technology. Their fog cannons are designed to rapidly produce a dense wall of fog that obscures visibility and helps deter intruders.
CastleOak is a PROTECT Certified Integrator. This designation reflects completion of PROTECT's full technical training program, covering fog cannon installation and mounting, alarm system integration, service and maintenance, and IP connectivity, the same disciplines every CastleOak fog installation is built on.
This is not a product we treat casually. A security fog system must be designed responsibly, installed professionally, and integrated properly into the broader security plan.
One Connected Ecosystem
Designed to integrate with Ajax alarm systems
CastleOak's security fog solutions are designed to work as part of a complete security ecosystem.
For many of our residential installations, that means integration with Ajax alarm systems. PROTECT fog technology offers Ajax-ready integration options, allowing the fog system to be incorporated into the same modern security experience rather than operating as an isolated device.
The result is a more seamless system for the homeowner:
- One coordinated security design
- One alarm ecosystem
- One app experience, in supported configurations
- One professional installation partner
- One layered plan for detection, notification, deterrence, and active protection
Security fog should not be an afterthought. It should be part of the system architecture.
Alarms, cameras, and fog: a layered approach
CastleOak believes the best security systems are layered.
Alarms provide detection
They identify the intrusion event the moment it happens, trigger notifications, and support the monitoring response.
Cameras provide verification and awareness
They help you see what is happening around the property, confirm the event, and review activity before and after an incident.
Fog provides active protection
It makes the protected space difficult to use, search, or move through during the intrusion itself.
Together, these layers create a more complete response than any single product can provide on its own.
Professionally designed, not randomly triggered
A fog cannon is powerful technology. That is why it must be installed with care.
CastleOak designs fog systems around the specific property, room layout, risk profile, alarm configuration, and homeowner requirements.
A proper design considers:
- The size and shape of the protected area
- The location of the fog cannon
- The most likely intrusion paths
- The correct activation logic
- False alarm prevention
- Alarm integration
- Client training
- Service and maintenance requirements
Responsible activation logic
Security fog should be activated only when the system conditions support it. The fog cannon may be configured around confirmed intrusion logic, specific sensor combinations, armed-state rules, or other designed safeguards depending on the property and the alarm architecture.
CastleOak will not treat a fog cannon like a simple plug-in device. It must be part of a professional security design.
Safety and peace of mind
Security fog is designed to obscure visibility, not to harm people.
PROTECT fog technology uses a security fog designed for occupied environments when installed and used properly. CastleOak will review the intended use, protected areas, activation approach, and homeowner guidance as part of the installation process.
As with any serious security technology, proper design and client understanding matter.
Is security fog right for your home?
Security fog is not necessary for every property. It may be appropriate if you have:
- High-value contents
- A vulnerable garage or storage area
- Valuable collections
- Jewelry, watches, art, or safes
- Frequent travel or extended absences
- A secondary property
- A concern about fast forced-entry theft
- A desire for a stronger active layer beyond alarms and cameras
CastleOak can assess whether security fog is appropriate for your property and where it would provide the most meaningful protection.
Frequently asked questions
What is a security fog cannon?
A security fog cannon is a device that rapidly releases dense fog into a protected space when triggered by a properly designed alarm event. The fog reduces visibility and makes it difficult for an intruder to continue moving through the area or locating valuables.
Does a fog cannon replace an alarm system?
No. Security fog is designed to work with an alarm system, not replace it. The alarm detects the intrusion and provides the trigger logic. The fog cannon adds an active layer of protection after the intrusion is confirmed.
Does it replace cameras?
No. Cameras and fog cannons do different jobs. Cameras provide awareness, evidence, and review. Security fog is designed to interfere with the intruder's ability to continue the theft.
Can security fog work with Ajax?
Yes. CastleOak designs fog cannon installations that can integrate with Ajax alarm systems using PROTECT's Ajax-ready integration options. This allows the fog layer to be incorporated into the broader security ecosystem rather than operating as a disconnected device.
Can it be controlled in the same app experience?
In supported configurations, the fog system can be integrated into the same Ajax security experience used for the alarm system. CastleOak will confirm the appropriate configuration based on the property, equipment, and desired operating logic.
Is the fog safe?
Security fog is designed for security applications and occupied environments when installed and used properly. CastleOak reviews placement, trigger logic, signage, and homeowner training as part of the installation process.
Will it set off my smoke detectors?
It can, and this is exactly why fog systems must be professionally designed. Security fog can trigger some smoke detectors, particularly photoelectric models, and in a home with monitored fire protection that can mean a fire dispatch. Detector type, detector placement, and activation logic are all reviewed as part of the CastleOak design process so the fog system and the life safety system work together rather than against each other.
Will the fog damage furniture, electronics, or artwork?
PROTECT's security fog is designed to be residue free. It is a glycol based fog that dissipates on its own and, according to the manufacturer, leaves no film or residue on furniture, electronics, artwork, or fabrics when the system is properly specified and installed. As part of the design process, CastleOak reviews the protected space and its contents so the correct model and fog volume are selected for the room.
How quickly does the fog fill the room?
The answer depends on the model selected, the size of the space, and the design of the installation. The system is specified based on the volume of the protected area and the desired protective effect.
Is this only for commercial properties?
No. Security fog has long been used in commercial environments, but it can also be a strong option for high-value residential properties, garages, secondary homes, and private storage areas.
What areas of the home are best suited for fog protection?
For many homes, the most effective location is the main entry area: the foyer, front hall, or mudroom where a forced entry is most likely to begin. A fog cannon positioned to cover the entry point can fill that space within seconds of a confirmed break-in, stopping an intruder at the threshold before they can move deeper into the home. Beyond entry areas, common locations include garages, safe rooms, storage rooms, jewelry areas, home offices, and studios: spaces where valuable property is concentrated and rapid visibility denial makes the biggest difference.
Can the system be hidden?
Some fog cannon models and installation approaches allow for discreet placement. The right approach depends on the room, ceiling and wall options, service access, and the required fog coverage.
What prevents accidental activation?
Proper design. CastleOak configures security fog as part of the broader alarm system and activation logic. The goal is to ensure the system activates only under the intended security conditions.
Does it require maintenance?
Yes. Like any serious security system, fog cannons require periodic service and proper maintenance. CastleOak will explain the maintenance requirements as part of the system design.
Is this suitable for a panic or duress scenario?
In some cases, security fog may be considered as part of a broader panic or duress strategy. This requires careful planning. CastleOak will review whether this is appropriate for the property and the intended use case.
A stronger final layer for the moments that matter
The best security system is not just about knowing that something happened. It is about reducing the chance of loss when the event is actually unfolding.
Security fog gives your alarm system an active response inside the protected area. It helps deny intruders the visibility and time they need to complete the theft.
For high-value homes, garages, and collections, it can be a powerful addition to a layered CastleOak security design.
