Service · ELV systems & surveillance · Nagpur

CCTV, fire alarm, access control and cabling.

Extra Low Voltage: CCTV, access control, fire alarm, public address, structured cabling, telephone and smart door locks. Designed and installed by the same engineering team that wires the electrical scope, so the LV power that runs the ELV stack is sized and protected correctly from day one.

What we install

Six ELV streams. One coordinated install.

The ELV stack lives downstream of the electrical install: UPS-backed circuits, dedicated server-room feeds, supervised fire-alarm circuits. We design both halves together.

ELV / 01

CCTV surveillance

IP cameras with full-colour night imaging, PTZ for perimeter, NVR / DVR with redundant storage, web and mobile clients, AI-based motion and intrusion detection.

ELV / 02

Access control & smart locks

Card, biometric (fingerprint / face) and PIN-based readers. Door-controller hardware, boom barriers and turnstiles for perimeter and parking. Smart door locks for residential and hospitality applications.

ELV / 03

Fire alarm & annunciation

Conventional and addressable systems, smoke and heat detectors, manual call points, sounders and strobe annunciators, central panel with battery backup, BMS integration, fire-pump start interlocks and smoke-extraction control to NBC and NFPA 72.

ELV / 04

Public address & background music

Zone-addressable PA for malls, hospitals, educational campuses and airports, with paging consoles, ceiling and horn speakers, music distribution and fire-evacuation override.

ELV / 05

Structured cabling & data

Cat 6 / Cat 6A LAN cabling, fibre backbones, RJ45 toolless connectors, patch panels and racks (server-room build-out), wireless access-point cabling, voice-data integrated runs.

ELV / 06

Telephone & intercom

EPABX, IP telephony, hospital nurse-call, video door phones and audio intercom for residential and commercial buildings, wired or wireless, integrated with access control where relevant.

Scope of work

What the ELV scope covers.

The ELV work runs on the same drawings and the same site team as the electrical install, from design through handover.

SCOPE / 01Design
Camera placement and coverage diagrams, cable routing, server-room sizing and supervised-circuit design, all produced in-house. See Engineering & design.
SCOPE / 02Power coordination
UPS-backed circuits for the NVR, server and fire-alarm panel, sized into the LT panel from day one rather than retrofitted after the building is up.
SCOPE / 03Installation
Cable trays, conduits, device placement, glanding, dressing and labelling, to the same standards as the electrical install.
SCOPE / 04Commissioning
Configuration, network setup, user enrolment, walk-test of every fire-alarm device, end-to-end functional test, training for the facility team.
SCOPE / 05Handover
As-built ELV drawings, device schedule, network configuration sheet, user manual and support contact, bundled with the electrical handover package.
