Public Address System | Gaadi Bachao

Gaadi Bachao team deploying IoT solutions for smart transport and waste management

Gaadi Bachao · PA System

Voice that reaches every corner — on demand.

Gaadi Bachao's IP-Based Public Address System replaces legacy analog PA setups with a fully networked, cloud-managed audio infrastructure. Every speaker is an IP endpoint — individually addressable, remotely configurable, and centrally monitored.

Whether it's a scheduled arrival announcement at a bus depot, an emergency evacuation alert across a municipality, or a live operator broadcast to specific zones — our system handles it with <50ms latency and crystal-clear audio.

Key Features

Everything you need to manage announcements at scale

Zone-Wise Broadcasting

Create unlimited zones — platform, concourse, parking, emergency zones. Broadcast to all zones or a targeted subset simultaneously.

Emergency Override

One-click emergency broadcast overrides all scheduled messages instantly. Supports pre-recorded emergency audio in multiple languages.

Scheduled Announcements

Pre-schedule daily, weekly, or event-based announcements. Time-triggered playbacks for bus arrivals, shift changes, or opening hours.

Cloud Dashboard

Manage all speakers and zones from a single web dashboard. Monitor volume, connectivity, health, and logs remotely from any device.

Live Operator Mic

Operators can broadcast live from any PC or mobile device. Perfect for live announcements, gate changes, or real-time updates.

Existing System Integration

Integrates with GPS vehicle tracking and CCTV systems. Trigger auto-announcements when a tracked bus enters a geofenced depot zone.

Multi-Language Support

Support for Hindi, English, and all major Indian regional languages. Upload pre-recorded TTS or custom audio files per zone.

99.9% Uptime SLA

Redundant cloud nodes, local fallback storage in every speaker unit, and 24/7 monitoring ensure announcements never fail when it matters most.

From installation to your first broadcast in just 4 simple steps

Site Survey

Our engineers map your zones, speaker count, and network topology. We design the optimal audio coverage layout for your facility.

IP Speaker Installation

PoE-powered IP speakers are installed in 1–2 days. Each speaker connects to your existing LAN or our 4G gateway for wireless deployments.

Cloud Configuration

Zones are configured via our cloud dashboard. Audio files, schedules, and emergency protocols are set up and tested remotely.

Go Live & Monitor

Your team controls broadcasts from any browser or mobile device. Health dashboards alert you if any speaker goes offline — before you even notice.

What Our Clients Say

Real results from real deployments across India

"The public address system integrated with our bus depot in 2 days. Now we can broadcast emergency alerts zone-wise in seconds. Gaadi Bachao's team was professional, fast, and genuinely helpful throughout."

— Amit Khurana, Operations Head, NCR Transport

"We replaced 10-year-old analog PA systems across 3 depots in a week. The cloud dashboard lets us push scheduled announcements from our office — no one has to be on-site. A complete game-changer."

— Sunita Rao, Depot Manager, BMTC Bangalore

"During a flood emergency last monsoon, we used the PA system to broadcast evacuation alerts to 12 wards simultaneously in Hindi and Marathi. It worked flawlessly under peak load. Truly life-saving technology."

— Vijay Patil, Municipal Commissioner, Nashik

Frequently Asked Questions

Everything you need to know before deploying

Do I need a dedicated server to run the PA system?

No. Gaadi Bachao's PA system is fully cloud-hosted. Your speakers connect to our cloud platform over LAN, WiFi, or 4G — no on-premises server needed.

Can we use our existing speakers and PA hardware?

In many cases, yes. If your existing speakers are passive, we install IP amplifier adapters. For active analog speakers we provide SIP-ATA converters. Our team assesses compatibility at no charge during the site survey.

What happens if the internet goes down?

Each IP speaker unit has local flash storage. Pre-scheduled announcements and emergency audio continue to play autonomously. When connectivity is restored, the system syncs with the cloud automatically.

Can it integrate with our vehicle tracking system?

Yes. Our PA system integrates natively with Gaadi Bachao vehicle tracking. When a tracked vehicle enters a geofenced zone, a pre-configured announcement is triggered automatically — ideal for bus arrival announcements.

How many speakers and zones can the system handle?

There is no hard limit. Our platform is built to scale — from a 10-speaker single-depot installation to thousands of speakers across a city-wide smart transport network. Zone groupings are fully configurable.
