Securing security-critical Outdoor Areas

Perimeter Protection with Audio and Visual Intervention

Reliable perimeter protection requires more than detecting what is happening. It requires the ability to intervene before a situation escalates. CCTV cameras, video analytics and sensors provide essential situational awareness, but observation alone cannot stop an unauthorised person from approaching a fence, entering a restricted area or damaging property.

Commend adds the missing dimension: proactive audio-visual intervention. With the AFLS-H-P IP Horn Speaker with Strobe Light, powerful voice announcements and configurable visual signals work together to attract immediate attention. Automatic messages or live announcements from the control room let security personnel address individuals directly, while the integrated LED strobe reinforces the message visually. The result is a security system that does not just see an incident – it can actively respond to it.

From detection to immediate intervention

When cameras, video analytics or sensors detect a person approaching a protected perimeter, the system can automatically trigger an event-specific voice message together with a highly visible light signal. This immediate audio-visual response makes it clear that the person has been detected and that the area is actively monitored – helping to deter unauthorised activity before the perimeter is breached.

Make every warning impossible to ignore

The visual signal immediately draws attention to the speaker and its announcement. Different colours and lighting patterns can support different scenarios – from preventive information and warning to deterrence and de-escalation.

This dual-sensory approach helps warnings attract attention quickly, even where ambient noise is high.

See the situation. Address it directly.

Once an event reaches the security control room, operators can assess the situation using available video and system information and intervene directly.

Live voice announcements allow operators to address individuals specifically, making it immediately clear that they have been detected. The strobe light helps attract attention to the announcement and reinforces the intervention visually. The integrated microphone also enables two-way audio communication where required.

This gives security personnel an immediate virtual presence at the perimeter – without first having to deploy staff to the location.

A visual and acoustic barrier for critical infrastructure

By combining video surveillance, detection, powerful audio and visual signalling, Commend transforms perimeter protection from passive observation into proactive intervention.

Unmistakable. Unmissable. Unambiguous.

See what is happening. Make sure they know they have been seen. And intervene before an incident becomes a security breach.

Perimeter Protection Solution

Protecting Critical Infrastructures

Securing power and water utilities is becoming more and more important. This is why power plants, transformer stations and facilities for the extraction, storage and purification of water are increasingly being fitted with combined video surveillance and PA solutions.

Even if there is no supervising staff present at the facility itself, the solution will respond to persons approaching the perimeters and premises and issue pre-recorded warnings. Staff at the central control room are provided with real-time data connections over the network, allowing them to address unauthorised persons directly and taking appropriate measures. Data centres are likewise treated as critical infrastructures and are beginning to take advantage of this solution.
