Unmistakable. Unmissable. Unambiguous
IP Horn Speaker with Strobe Light
OverviewThe AFLS-H-P is the world’s first IP-based horn speaker that combines high-volume audio broadcasting capabilities with a powerful, configurable LED strobe light in a single device. Equipped with these unique capabilities, it is designed to effectively amplify any message – from preventive warning and de-escalation announcements to alerts and everyday information broadcasts – by addressing the eyes as well as the ears.
Attention in a fraction of a second
Impossible to ignore
The human brain is a masterful detector of change and is evolutionarily programmed to respond with lightning-fast reactions to sudden environmental stimuli (predator/prey).
While acoustic warning signals and voice announcements play an essential part in security technology, our visual system is biologically wired to react much faster when stimulated by light signals. A powerful flashing light perfectly simulates the type of movement that ‘tricks’ our brain into focussing immediately and automatically on the light source.
In emergency situations and security applications, every second (or even fraction of a second) counts. A well-balanced combination of light and sound ensures that your warning is not just heard but triggers an instant cognitive response in the recipient.
Immediate attention
Visual signals are processed even faster than purely auditory signals.
Cuts through ambient noise
In sound-polluted environments (e.g., on-road traffic or industrial facilities), audio-only announcements may be drowned out, while the strobe light instantly draws people’s attention to the speaker and the announcement.
Faster response
The combined audiovisual approach effectively reduces response times.
Universal intelligibility
Colour codes (e.g., red signalling danger), as well as light effects (e.g., flashing) are instantly recognisable across language barriers. As a result, the message is received and understood instinctively without further explanation, even by hearing impaired persons.
Proactive remote addressing
The combination of a live audio message with a visual warning light enables instant protective intervention, deterring or de-escalation via a remote point of control. This enables immediate on-site presence without the need to deploy security staff.
Audio and Visual Signals
Dual-sensory principle
Technical Data
- Extra-high volume capacity: A high-efficiency amplifier powered by SmartAmp technology delivers a maximum of sound volume while keeping energy consumption at a minimum.
- Dynamic LED strobe light: The light source can be configured individually to suit different scenarios, with options including various colours and flashing patterns.
- IP66 and IK10 rated, built to withstand harsh ambient conditions
- System integration: Packed with on-board features from SIP to API and I/Os, including ONVIF support, the speakers integrate smoothly and easily into VMS, PSIM or other security management platforms.
- AI-assisted two-way communication: The integrated microphone (which can also be disabled) leverages AI-based noise and echo suppression technologies to ensure crystal-clear audio communication.
- Cyber Security ‘By Design’: Protection against cyber attacks is essential, particularly in exposed outdoor areas. Thanks to Active Device Management (Symphony Service), your speakers receive automatic updates and remain optimally protected against cyber threats at all times.
- Genuine single-wire solution: While conventional systems often require separate wiring for audio lines and strobe lights, the Commend IP speaker offers an all-in-one Ethernet cable connection (standard Power over Ethernet / PoE).
- Intelligent Volume Control (IVC): The system continuously measures ambient noise levels and adjusts the volume setting automatically for optimum clarity and intelligibility.
- Remote System Health Monitoring: Using built-in speaker-to-microphone monitoring and end-to-end connection testing, the system ensures continuous functionality without the need for manual inspections.
- Audio Monitoring: The speaker comes with the ability to continuously monitor the acoustic environment, which allows it to automatically trigger alerts in case a pre-defined noise level is detected. The noise level readings can be relayed to a central system at definable intervals – e.g., to populate the noise map of a city or industrial facility with current values.
From reactive observation to proactive intervention
Applications
Surveillance cameras are limited to the observation of events, without the ability to intervene. The Commend Symphony IP Horn Speaker lets you intervene directly, helping you to protect lives and assets. Transform your security system into a proactive tool for remote-controlled action:
Event-specific trigger mechanism: Cameras and sensors detect an incident and trigger an automatic announcement, accompanied by an attention-compelling light signal.
Direct-address function: Staff at a central control desk can use their desktop microphone to make live announcements, accompanied by appropriate light signals to attract attention and support de-escalation.
Protection of perimeters & critical infrastructures
Safeguard critical infrastructures, data centres and large company premises with a combined visual and acoustic barrier that deters intruders before they can reach or breach the fence line or causes one to flee the scene.
Smart Cities & Remote Intervention
Improve video surveillance through efficient remote control, using audio announcements and light signalling to de-escalate critical situations in inner-city environments.
Industrial facilities & large-scale company premises
Reliable alarm support for industrial applications, with additional light signals in the form of flash bursts to prevent audio messages from being overheard.
Safe evacuation guidance
A clearly visible light signal directs evacuees in quick and easily understandable fashion to emergency assembly points. At the same time, the built-in two-way communication line helps to provide reassurance and ensure a well-coordinated evacuation process.
Protection of open spaces and sensitive areas
Leverage the interplay of light and automatic audio playback to kindly but firmly warn off people, e.g. if they are not allowed on the premises outside business hours or without proper authorisation.
Connection and Control Options
Ethernet, USB port, inputs and outputs, line-in

Frequently asked questions about the IP horn loudspeaker with strobe light
What makes the Commend Symphony IP Horn Speaker AFLS-H-P stand out?
In addition to providing high volume and excellent speech intelligibility, the device features a unique built-in LED strobe light that engages the visual sense to attract people’s attention to announcements being broadcast.
Which colours are supported by the strobe light?
Depending on the application scenario and the desired effect (e.g., warning, deterring or de-escalating), various lighting modes such as flashing, flashing speed or steady light can be configured, and the colours red, green, blue, white, orange and pink are supported.
Why is direct confrontation the most effective way to ward off intruders?
Studies and statistical evaluations conducted by security service providers have shown that the effectiveness of IP Speakers rests on three key functions:
- Removing anonymity: Perpetrators will feel safe as long as they believe themselves to be undetected. Addressing an intruder directly, as in “The person in the red jacket, please leave the premises immediately!” lets them know that they have been detected and are being monitored.
- Raising an intruder’s risk of detection: According to the “Rational Choice Approach” in criminology, perpetrators will give up once their risk (of being detected) exceeds their envisioned benefit.
- Shock effect: Sudden acoustic signals or voice sound will trigger an instinctive escape reflex. An additional visual signal can amplify this effect significantly.
Is the speaker also suitable for extremely noisy environments?
Yes, the speaker is built specifically for use in environments that are subject to high and changeable levels of noise pollution. Its built-in Intelligent Volume Control (IVC) function allows it to automatically adjust the volume setting to the ambient noise level. Built-in Smart Amp technology enables extra high volume amplification without the need for any additional power source.
Can the device withstand harsh environmental conditions?
Absolutely. The IP Horn Speaker features a highly robust and durable design that ensures reliable operation even under harsh conditions. It also offers high-level protection against vandalism (IK 10) and is protected against dirt and powerful water jets in accordance with IP66. A waterproof and breathable seal prevents condensation from forming inside the housing when there are significant temperature differences.
How is two-way communication possible with a horn speaker?
The speaker leverages OpenDuplex® technology in combination with AI-based noise and echo suppression (Cleans Voice from Noise). This allows it to efficiently suppress background noise and highlight the voice sound being transmitted.
How does the IP Horn Speaker have to be connected and powered?
Since the system eliminates the need for complex wiring, it can be integrated into a network using a standard Power over Ethernet (PoE IEEE 802.3af/at) connection via the RJ45 port. This connection automatically provides the device with the required operating power, eliminating the need for PoE+ or any additional power supply.
