Public address and intercom
Clear announcements, background music and two way communication, from a single reception desk to an entire industrial site.
In short
Astaa Technologies installs public address, mass notification and intercom systems for commercial, industrial and education sites. We use Bosch and TOA for PA and voice alarm, Axis network speakers and horn speakers for IP audio, and Axis and 2N video intercoms for entrances and help points.
AI that listens for trouble
Audio analytics detect shouting and aggression and can trigger an automated warning message, a camera preset and an operator alert at the same time, turning the PA system into an active safety tool.
How we apply AIIntelligible audio everywhere
We model coverage and speaker placement so messages are understandable in lobbies, corridors, car parks and noisy plant areas. Zoning lets you page one floor, one building or the whole site.
IP audio that scales
Network speakers connect over standard Ethernet with power over Ethernet, which simplifies cabling and lets you manage schedules, zones and health centrally with AXIS Audio Manager.
Video intercom at the door
IP video intercoms let reception or the control room see and speak to visitors, then release the door remotely. Calls can be routed to phones, desks or the VMS.
Capabilities
Paging and background music
Zoned announcements and scheduled music for offices, retail and hospitality.
Mass notification
Pre recorded emergency messages triggered manually or by fire and security events.
Horn and outdoor speakers
Weatherproof horn speakers for yards, terminals and industrial plants.
Video intercom
Axis and 2N door stations with remote door release and video recording.
IP audio management
Central control of zones, volumes and device health over the network.
Integration
Links to fire alarm, access control and the VMS for coordinated response.

Brands we specify
We recommend equipment based on risk, integration needs and lifecycle cost, then supply genuine products through authorised channels.
Frequently asked questions
Can a PA system be used for emergency evacuation?
Yes, when it is designed as a voice alarm system and integrated with the fire alarm. We specify certified equipment where codes require it and configure automatic evacuation messages.
What is the benefit of IP network speakers?
Network speakers need only an Ethernet cable for audio and power, can be grouped into zones in software, and report their status, so faults are found before an announcement is missed.
Do you install intercoms for gates and car parks?
Yes. We install video intercoms at pedestrian and vehicle gates with remote release, recording and links to access control.
