Intrusion Alarm System

PIR/microwave sensors, glass-break, dual-path monitoring

Overview

What we offer

A complete toolkit — purpose-built for your environment.

An intrusion alarm system is an electronic security system that detects unauthorised entry or movement within a protected area and responds by raising a local alarm and/or transmitting an alert to a central monitoring station (CMS) or designated contacts. It forms the electronic perimeter around your premises — detecting intruders before they access valuable assets, causing them to abandon the intrusion, and alerting security personnel or law enforcement in time to intervene.

Modern intrusion alarm systems go far beyond the simple bell box and motion detector of earlier generations. Contemporary systems use multiple detection technologies working in combination — passive infrared (PIR) motion detection, microwave detection, acoustic glass break sensing, vibration analysis, and outdoor beam detection — to provide high confidence detection with minimal false alarms. Dual-path communication (IP primary and GSM backup) ensures alarm signals reach the monitoring station even if an intruder has cut the telephone line or internet connection. Video verification — triggered camera clips or live video feeds transmitted with the alarm — enables CMS operators to confirm a genuine intrusion before dispatching a police response, reducing response time and improving the probability of an in-progress apprehension.

In Bangladesh, burglary, after-hours theft, and commercial break-ins are significant risk exposures for businesses and high-net-worth residences. Banks and financial institutions face targeted attacks on ATMs and branch premises. Garment factories face warehouse theft of finished goods and raw materials during nighttime and weekend hours. Commercial offices face theft of IT equipment, which has become a primary target for organised crime groups. Residential properties in Dhaka's affluent suburbs — Gulshan, Baridhara, Banani — face targeted residential burglary. We design and install intrusion alarm systems using Hikvision and Ajax — a technically superior combination of established enterprise CCTV integration capability and Europe's most advanced wireless alarm platform — to deliver systems that detect reliably, communicate redundantly, and integrate seamlessly with your broader security infrastructure.

These solutions ensure instant threat detection, anti-tamper protection and centralized control — securing commercial facilities, financial institutions and critical infrastructure with reliable and intelligent perimeter security.

PIR Motion Detectors

Single-technology PIR detectors (passive infrared) detect the heat signature of a moving human body within the protected zone. Dual-technology PIR+microwave detectors require both technologies to trigger simultaneously — dramatically reducing false alarms from insects, small animals, and temperature changes that commonly trigger single-technology PIR detectors in Bangladesh's tropical environment.

Glass Break Detectors

Acoustic glass break detectors (listening for the specific frequency signature of breaking glass) and shock detectors (detecting the vibration of glass impact) protect glazed façades, windows, and display cases — providing detection before an intruder enters the protected space rather than after crossing the threshold.

Door & Window Contacts

Magnetic contacts on all doors and windows provide zone monitoring at the fundamental access boundary. Concealed contacts eliminate the visual indicator of alarm coverage that opportunistic intruders use to identify protected versus unprotected entry points.

Vibration Sensors

Vibration analysis sensors on walls, floors, safes, and high-value storage containers detect the low-frequency vibration signature of drilling, cutting, or impact attacks — providing alarm triggering before penetration is achieved. Essential for bank vault and ATM protection.

Outdoor Beam Detectors

Passive infrared and active infrared beam detectors create invisible detection lines across open areas, driveways, and perimeter zones — giving advance warning of intruder approach before they reach the building envelope. Quad-beam detectors with automatic gain control minimise false alarms from weather conditions including Bangladesh's heavy monsoon rain.

Process

How it works

One accountable team from first site visit to handover — certified engineers, manufacturer-trained installers, and documented compliance at every stage.

  1. Security Risk Assessment

    We conduct a structured security risk assessment of your premises: identifying entry points (doors, windows, skylights, hatches), internal high-value zones (server rooms, safes, cash areas, warehouses), perimeter vulnerabilities (climbable walls, unlit areas, blind spots), and existing security measures. We assess the threat profile relevant to your property type and location — informing the detector types, alarm grade, and monitoring response required.

  2. System Design

    We produce a zone-by-zone alarm system design: detector types and placement at each zone, alarm panel specification, keypad locations, sounder and strobe positions, outdoor beam detector positions, dual-path communicator specification, and CMS monitoring service selection. The design is graded to EN 50131 Grade 2 (domestic/light commercial), Grade 3 (bank branches, commercial), or Grade 4 (high-risk, high-value installations) as appropriate.

  3. Supply & Procurement

    Hikvision DS-PD series detectors, alarm panels, and communicators are procured through authorised channels. Ajax wireless alarm devices arrive factory-fresh in tamper-sealed packaging. All devices are verified for firmware currency before installation — a critical step for cybersecurity integrity, since outdated firmware on alarm communicators can be exploited by technically sophisticated attackers.

  4. Installation

    Our alarm installation teams mount all detectors, keypads, sounders, and communicators to manufacturer specifications. Wired systems use 4-core and 6-core alarm cable terminated in tamper-monitored junction boxes. Ajax wireless devices are mounted with wall plugs and anti-tamper screws. All wired cable routes are in conduit where surface-exposed. Outdoor beam detectors are aligned and sensitivity-tested against known-good targets at the time of installation.

  5. Programming & CMS Enrolment

    Alarm panels are programmed with zone names, alarm types (instant, delay, 24-hour), access codes, and communicator parameters. CMS monitoring account is created with your contact list, key holder hierarchy, and police call protocol. A full commissioning test is conducted: every detector is triggered individually, alarm transmission to CMS is verified, and all sounders and strobes are confirmed operational. Anti-masking tests verify that detectors respond to masking attempts.

  6. Training & Handover

    You receive user training on arming, disarming, alarm acknowledgement, and code management. Administrators are trained on zone bypass, programming adjustments, and CMS communication testing. You receive the system commissioning certificate, equipment warranties, and a user guide. Annual preventive maintenance contracts cover detector cleaning, battery testing, sounder and strobe verification, and CMS communication test.

Applications

Built for every industry

Where this solution is deployed — and the compliance environment each sector brings with it.

Deployment site for intrusion alarm system

Banking & Financial Services

Bank branches, ATM sites, and cash transit vehicles require intrusion alarm systems that satisfy Bangladesh Bank security requirements and provide the rapid, verified response that minimises loss when alarms occur. We deploy dual-technology detectors in branch interiors, vibration sensors on vault doors and ATM enclosures, outdoor beam detectors at branch perimeters, and dual-path communicators with 24/7 CMS monitoring for all locations.

Garment & Textile Factories (RMG)

Warehouse intrusion, after-hours theft of finished goods, and targeted theft of raw materials (including fabric, dyes, and accessories) are significant loss exposures for RMG factories. We deploy perimeter beam detection, warehouse interior PIR coverage, access door contacts, and CMS monitoring with video verification — providing documented security evidence for insurance premium reduction and BGMEA audit compliance.

Deployment site for intrusion alarm system

Corporate Offices & Commercial Buildings

Commercial offices face IT equipment theft, document theft, and opportunistic break-ins during holiday periods. We provide addressable alarm systems with multiple access partitions — office areas armed by last-out, IT server rooms armed on 24-hour continuous protection, and executive areas independently managed. Integration with access control enables automatic alarm arm/disarm when the last authorised person exits a zone.

High-Net-Worth Residences

Dhaka's premium residential areas require alarm systems that provide genuine protection without the false alarm frequency that causes homeowners to disable the system in frustration. Ajax wireless systems with dual-technology motion detection and pet-immune PIR options deliver reliable protection in furnished residential environments without requiring structural cabling — important in existing properties.

Hotels & Hospitality

Hotel security requires intrusion protection for back-of-house areas (kitchens, engineering, linen stores, food stores) outside operating hours, executive suite protection during high-profile guest visits, and safe room protection. Alarm system integration with the hotel's security management platform provides a unified incident picture for the security manager.

Educational Institutions

Schools and universities require after-hours protection for computer labs, science laboratories (expensive equipment and chemicals), library collections, and examination storage. Addressable alarm systems with partition management allow different areas to be armed and disarmed independently by authorised staff — without requiring every keyholder to know the master arming code.
