Access Control & Video Surveillance for High-Rise Apartment Buildings in Dhaka

Dhaka's skyline has been transformed over the past two decades by the rapid rise of high-rise apartment development. Buildings of 15, 20, and even 30 or more floors now define the residential landscape in Gulshan, Banani, Baridhara, and Bashundhara. These buildings pose security management challenges that simply do not arise in low-rise or mid-rise residential development: managing resident and visitor access across dozens of floors, securing lift systems that serve as the primary vertical circulation, monitoring extensive stairwells and underground car parks, and managing vehicle access to basement parking across a high-volume building.

This article addresses the specific access control and surveillance considerations for high-rise apartment buildings in Dhaka — with practical technology specifications and context for how Bangladesh's high-rise residential market is evolving.

High-Rise Specific Challenges

High-rise buildings amplify the challenges of residential security in several specific ways.

Vertical security layers: A 25-floor apartment building has 25 distinct residential floors, each potentially accessible from a shared lift lobby. Controlling which residents and visitors can access which floors — and preventing someone on floor 12 from casually accessing floor 20 — requires lift control integration, not just lobby access control.

Large resident populations: A 25-floor building with 4 apartments per floor has 100 residential units. With an average of 4 residents per apartment, the building houses 400 residents. Managing credentials for 400 residents — issuing cards, deactivating credentials when residents move out, granting temporary visitor access — requires systematic credential management, not manual processes.

Multiple service providers: High-rise buildings receive visits from delivery personnel, maintenance contractors, cleaners, healthcare workers, and other service providers on a daily basis. Temporary access management for these visitors, without compromising resident security, requires a visitor management workflow integrated with the access control system.

Stairwell security: In a high-rise building, stairwells span the full height of the building and connect every floor. They are a security vulnerability — a person who enters the building and reaches a stairwell can potentially access any floor. Stairwell CCTV coverage and access control (from corridor to stairwell) address this risk.

Basement car park: High-rise apartment buildings typically have one to three basement levels of parking. The basement is connected to the building's main structure and, if not properly secured, provides an alternative route for unauthorised persons to access the building from the car park.

Floor-by-Floor Access Control: Lift Card Integration

Lift card integration is the single most effective access control mechanism for multi-floor high-rise buildings. It restricts lift access so that each resident's card can only call the lift to their designated floor — preventing non-residents from using the lift to reach floors they have no access to.

Technical implementation:

Lift card integration is implemented through a connection between the building's access control system controller and the lift control panel. When a resident presents their RFID card to a card reader installed in the lift car (or at the lift lobby button panel), the access control system validates the card and signals the lift controller to enable the button for the resident's designated floor — and only that floor.

Without lift card integration, all floor buttons in the lift are accessible to all users. With lift card integration, the floor buttons are disabled by default — only the buttons corresponding to the authenticated card holder's authorised floors are enabled when the card is presented.

For a building where most residents live on a specific floor (one residential unit per floor family in a luxury building, for example), this means a resident's card enables only the ground floor (main lobby) and their specific residential floor. They cannot press floor 12 if they live on floor 8.

Visitor floor access:

When a resident grants entry to a visitor via the video intercom system, the visitor access grant can include a time-limited floor button enablement — the lift button for the resident's floor is enabled for a 30-minute window, allowing the visitor to travel directly to the correct floor without being able to access other floors.

Emergency override:

During fire alarm activation, lift cards must not restrict access — the lift controller switches to fire service mode (all calls cancelled, lifts return to ground floor, doors remain open or close only under specific conditions per the lift controller's fire service programming). The access control system is configured to suspend lift card restrictions automatically when the fire alarm input is active.

Visitor Video Intercom: Lobby to Apartment

The visitor entry process in a high-rise apartment building starts at the main lobby entrance. A video intercom panel at the lobby allows visitors to call individual apartments.

Lobby intercom panel: The panel displays a directory or alphanumeric keypad. The visitor types the apartment number or searches the resident's name. The call is placed to the apartment's indoor monitor or smartphone app.

Apartment indoor monitor: A touchscreen panel inside the apartment (typically mounted near the apartment entrance) displays the visitor's face (captured by the lobby panel camera) and the lobby entry camera view. The resident hears the visitor over the intercom audio. The resident decides to admit or decline.

Remote admission via smartphone: If the resident is not at home, the call forwards to their smartphone via the building's Wi-Fi or internet connection. The resident can see the visitor's face, speak with them, and press a virtual unlock button on the app to open the lobby door — from anywhere in the world.

Delivery management: For parcel deliveries where the resident is away, many high-rise buildings implement a dedicated delivery area or a parcel locker in the lobby. The resident can grant the delivery person access to the lobby (but not to their floor) via the intercom app, allowing the parcel to be left in the lobby or in a secure parcel locker.

Multi-building complexes: Where a residential complex has multiple high-rise towers, a single intercom management server handles all buildings. Residents in building A can be called from building A's lobby panel; residents in building B from building B's panel. The panels cannot cross-call between buildings unless the system is specifically configured for this (relevant for large family apartments where family members live in adjacent towers).

CCTV: Lift Cars, Stairwells, and Basement Car Park

Lift Car CCTV

CCTV inside lift cars is standard in any professionally managed high-rise apartment building. The lift car camera captures all persons riding the lift — providing both deterrence (inappropriate behaviour in lifts is deterred when visible CCTV is present) and evidence for any incident involving lift car occupants.

Lift car cameras must be compact and vandal-resistant. Dome cameras with a wide-angle (approximately 108° horizontal) lens cover the full lift interior from a corner-mounted position. The camera must maintain image quality in the variable and sometimes challenging lighting conditions of a lift car — recessed downlighting, fluorescent strips, or LED panel lighting creates different luminance characteristics than standard room lighting.

Wiring for lift car cameras must accommodate the lift's movement — flexible conduit or trailing cable within the lift shaft is used to connect the lift car to the fixed wiring in the lift machinery room. This wiring installation requires coordination with the lift contractor and must be carried out by personnel familiar with lift safety regulations.

Stairwell CCTV

Stairwell CCTV is a key security element for high-rise buildings. Cameras are positioned at each stairwell landing — typically at floor level — covering the stairwell area and the door to the corridor. At a minimum, the ground floor stairwell entry and the top floor stairwell entry are covered; ideally, every other floor landing is covered.

Wide-angle fisheye cameras are efficient for stairwell coverage — a single camera positioned at a landing ceiling corner can cover the landing, the stair flight above, and the stair flight below in a single field of view, reducing the camera count needed for comprehensive stairwell coverage.

Stairwell cameras must have IR illumination — stairwells in high-rise buildings often have low ambient light levels, particularly in buildings where natural lighting is minimal. IR illumination ensures useful image quality in all lighting conditions.

Basement Car Park CCTV

The basement car park requires comprehensive CCTV coverage due to the combination of poor natural lighting, enclosed space, limited natural surveillance opportunities, and the presence of resident vehicles and stored property.

Coverage requirements:

• All parking bays — cameras positioned between rows to cover bays from the driving aisle side, capturing vehicles and persons in the bay
• All traffic lanes — cameras at lane ends covering traffic movement direction
• Lift lobby in the basement — persons entering the building from the basement through the lift
• Stairwell entries in the basement — persons entering the building stairwell from the basement level
• Basement entry and exit ramps — ANPR cameras for vehicle identification at entry/exit

Lighting integration: Basement car parks that use motion-sensor lighting (lights off when no one present, on when motion detected) can cause CCTV issues — cameras switching between well-lit and very poorly lit environments when lighting triggers and de-triggers. Configure parking area lighting to maintain a minimum base illumination level (rather than full off) so that camera performance is maintained even during low-traffic periods.

ANPR Vehicle Access at Basement Entry

ANPR at the basement car park entrance serves two functions: identifying and admitting resident vehicles automatically, and providing a vehicle entry/exit log for security investigations.

System configuration for a high-rise apartment building:

A single barrier lane at the basement ramp entrance with ANPR camera provides adequate access control for most buildings. For larger complexes with separate entry and exit ramp systems, one ANPR camera and barrier per lane is required.

Resident vehicles are pre-registered by the building management — residents submit their vehicle registration plate when taking up tenancy. The ANPR database is updated by the building management team as residents change vehicles or move in and out.

Visitor vehicle management: Visitor vehicles approaching the basement entry are handled differently in different building management configurations. Some buildings allow open visitor access to basement (visitor parks and then uses video intercom to be admitted to the building). Others require visitor vehicles to be pre-authorised by a resident (the resident adds a time-limited visitor vehicle plate to the ANPR system via the management app) before the barrier opens. The latter approach provides better vehicle-level control.

Bangladesh Building Management Association (BMA) Requirements

High-rise apartment buildings in Bangladesh are managed by Building Management Associations (BMAs) — committees of apartment owners who collectively manage common area maintenance, building services, and security. The BMA is the decision-making body for security system procurement and management.

BMA responsibilities for security include:

Security system procurement: The BMA conducts or approves procurement of CCTV, access control, intercom, and fire safety systems for the building. Procurement is typically funded by service charge contributions from all apartment owners.

Security staff management: The BMA employs or contracts security guards for the building's main gate and lobby. The BMA sets guard shift schedules and performance requirements.

System maintenance: The BMA is responsible for ensuring that security systems are maintained — cameras operating, NVR recording, access control functional, fire alarm tested. This typically requires an AMC with a security technology service provider.

Credential management: The BMA manages the issuance and deactivation of resident RFID cards. When a new resident moves in, the BMA issues their access card. When a resident moves out (or a tenant changes), the BMA deactivates the outgoing resident's card and issues one to the incoming resident.

For BMA procurement in Bangladesh, the most practical approach is to engage a security technology integrator (like SSAL) to design the full system, supply and install all hardware, commission the software, train BMA-appointed staff in system management, and provide an AMC for ongoing maintenance.

Dhaka High-Rise Apartment Market Context

Dhaka's premium high-rise apartment market is concentrated in Gulshan, Baridhara, Banani, and North Bashundhara. Buildings in these areas include completed developments by Sheltech, NAVANA Group, Rangs Properties, Rising Group, and various other developers, as well as ongoing new projects responding to sustained demand for premium urban residential space.

Security technology in this market segment has progressed significantly in the past five years. Buildings completed in 2018 or earlier often have basic CCTV and mechanical keypad entry at lobby doors. Buildings completed from 2022 onward increasingly feature IP video intercom, RFID access control with lift card integration, ANPR at basement entry, and 4 MP CCTV in common areas — reflecting rising resident expectations and developer awareness that security quality is a selling point.

For buildings in the 2018 or earlier vintage that lack modern security infrastructure, SSAL provides retrofit security programmes — upgrading CCTV to IP cameras, installing video intercom at lobby entrances, adding ANPR at basement entries, and upgrading to RFID access control — without major structural disruption to the building.
