01
Read the plate
An ANPR / ALPR camera or local processing unit captures the registration number.
Vehicle alerts · Fuel station audio
Every vehicle alert,
spoken clearly.
A 30W IP horn speaker that turns an API trigger into a clear, vehicle-specific announcement.
Send the vehicle number and alert status from your ANPR platform. The SIPTOUCH speaker generates the spoken message locally and broadcasts it at the station.
Product datasheets are available to registered SIPTOUCH partners.

How it works
From number plate to spoken alert.
The client application makes the vehicle-status decision. The speaker takes the event and gives it a voice.
02
Validate the status
The authorised client platform checks PUCC or other vehicle information.
03
Send the API event
The application sends the number and alert status to the selected IP speaker.
04
Announce locally
On-device text-to-speech creates the message for the 30W horn speaker.
Designed for fuel station alerts
Tell the driver what needs attention.
An automatic announcement IP speaker can name the vehicle and clearly state the alert. Each message is assembled from information received through the client API.
For fuel stations, petrol pumps and fuel retail sites, use this automatic announcement speaker in a wider ANPR / ALPR workflow. The client system handles vehicle recognition and status validation; the IP speaker delivers the alert through local text-to-speech.
PUC / PUCC
Pollution certificate alert
“Attention please. Vehicle number HR51 1234, your PUC has expired.”
Insurance
Insurance expiry alert
“Attention please. Vehicle number HR51 1234, your insurance has expired.”
Other statuses
Configured vehicle messages
Non-compliance or End-of-Life (EoL) alert wording can be mapped to the status codes supplied by the client platform.
A connected station workflow
Fits into your existing ANPR setup.
For projects combining ANPR / ALPR cameras, an LPU and central monitoring, the SIPTOUCH text-to-speech IP speaker provides the voice announcement endpoint.

Connect through the site IP network. Integrate the speaker API with the agreed ICCC / VMS event flow.
One clear responsibility at each step
Camera / LPU: captures or processes the vehicle number.
Client application: validates PUCC status through its authorised source, such as NIC VAHAN / Parivahan, and decides which alert to send.
SIPTOUCH speaker: receives the configured event, generates the spoken message locally and broadcasts it.
Any government API access, display control or challan process remains part of the wider client solution.
At a glance
ST-SIP-VAS30
A 30W fuel station IP speaker for automatic vehicle announcements, API-triggered alerts and IP public-address applications.
For project specifications and BOQs, this solution can be described as an outdoor 30W IP PoE horn speaker with a built-in Class-D amplifier, API-triggered vehicle-number announcements and local text-to-speech (TTS). In an ANPR/ALPR fuel-station workflow, the camera, LPU or client platform supplies the recognised vehicle number and authorised PUC/PUCC, challan or insurance status. Match PoE/DC, IP66, UV-stabilised ABS and integration requirements to the selected ST-SIP-VAS30 configuration and approved datasheet.

Questions, answered
Before you integrate.
What is an automatic announcement IP speaker?
It is an IP-connected speaker that plays a message automatically when the client application sends a trigger. With text-to-speech, the vehicle number and alert can be spoken without preparing a separate recording for every vehicle.
Does the SIPTOUCH speaker read the number plate?
Number-plate recognition is performed by the ANPR / ALPR camera or client-side processing system. The speaker announces the vehicle number included in the API event.
Can it announce PUC, PUCC, challan or insurance alerts?
Yes. When the client system sends the vehicle number and authorised status in the API payload, the speaker’s local text-to-speech can announce the configured alert. Vehicle recognition and status validation remain with the client-side camera, LPU or platform.
Can this fuel station speaker connect to ICCC or VMS?
The speaker can be integrated with a compatible client application using the agreed API and event workflow, including SIP-based paging in a wider IP public-address system. Confirm the payload, routing and required configuration with the project integrator.
What should a tender or BOQ specify for this solution?
Describe the required outdoor IP horn speaker output, built-in amplifier, API trigger, local TTS, network and enclosure parameters, and ANPR/LPU/VMS integration. Check each requirement against the approved ST-SIP-VAS30 configuration and datasheet before finalising compliance.
