CCTV Camera System for Apartment Building & Housing Society in Bangladesh — 2026 Complete Guide

Written by CSL Systems engineers who have installed CCTV in 200+ apartment buildings across Dhaka — from 6-storey walk-ups in Mirpur to 25-storey towers in Gulshan and Bashundhara, plus gated societies in Bashundhara R/A, DOHS, and Purbachal.

Apartment CCTV in Bangladesh is not a single-owner decision — it is a housing society (samity/committee) decision involving 20-200 flat owners, budget constraints from monthly service charge, tenant privacy concerns, and the practical reality that “everyone’s responsibility becomes no one’s responsibility”. This guide covers everything a Dhaka apartment building committee needs to plan, budget, install, and maintain a professional CCTV system that satisfies both security concerns and community consensus.

1. Why apartment CCTV is different

The unique challenges of Bangladeshi apartment CCTV:

• Multi-owner budget approval — 30-40 flat owners must agree on a shared expense. Rejection over ৳5,000/flat is common.
• Common area privacy balance — corridors, lift lobbies, parking are shared. Residents want security but not surveillance of their front doors.
• Tenant vs owner dynamics — tenants pay rent (not service charge) but use the building. Their input often overlooked.
• Maintenance responsibility — who pays when a camera breaks? Society fund, individual flat, or CCTV vendor AMC?
• Committee turnover — new committee every 2 years may forget original decisions, remove cameras, or refuse to fund maintenance.
• Retrofit challenges — old buildings don’t have cable conduits; drilling through walls needs owner permission.

2. Zone-by-zone camera plan for a typical apartment building

Zone A — Main gate + guard room

The single most important zone. Cover the main gate from two angles — one wide showing full gate + street, one narrow at 8mm focused on incoming vehicle license plates. Add ANPR (auto number plate recognition) for buildings with heavy vehicle traffic.

Additional: camera pointing at guard room desk (guards logging visitor entries) and visitor register area.

Zone B — Lift lobby (each floor)

One camera per floor’s lift lobby. Face-height wide angle so anyone waiting for lift or entering flat corridor is captured. NEVER inside flats or pointing at individual flat doors from close range — respect privacy.

Zone C — Lift interior

Optional but recommended. Small dome camera in lift ceiling covering the whole cabin. Deters violence, harassment, and theft during lift rides. Legal in Bangladesh with visible signage.

Zone D — Staircase entry/exit points

Cover ground floor stairs entry + roof access door. NOT every floor’s staircase landing (privacy overreach) — only entry/exit critical points.

Zone E — Parking area (basement + open)

Cover each parking bay in a wide overview. For basement parking, ColorVu cameras essential due to poor lighting. One camera every 3-4 parking bays. Cover the vehicle entry/exit ramp with a dedicated camera.

Zone F — Rooftop

Cover rooftop access door + water tank + generator area. Anti-suicide watch is a growing concern in Bangladeshi apartments — some societies request rooftop camera pointing at parapet edge (with mental health support signage, not just surveillance).

Zone G — Generator + electrical room

These rooms house expensive equipment. Cover door + interior overhead. Motion-triggered alerts for after-hours access.

Zone H — Community facilities (if any)

Community hall, gym, pool, children’s play area, rooftop garden — one camera each entry. Do NOT install inside changing rooms, toilets, or worship areas.

3. Camera count by building size

4. Committee approval — how to build consensus

The biggest obstacle to apartment CCTV is not technology — it’s getting 40 owners to agree. Proven approach:

1. Committee proposes an initial plan — 3 vendor quotations, camera positions marked on building floor plan
2. Owner meeting presentation — CSL Systems (or vendor) presents 30-minute talk covering security incidents in similar buildings, budget breakdown, ongoing costs
3. Voting — 2/3 majority required; specify who pays what (per-flat one-time contribution + service charge increase)
4. Written resolution — signed by committee secretary + president, kept in society records
5. Public notice — posted at building entrance stating CCTV recording in progress

5. Ongoing costs — beyond installation

Committees often forget the ongoing costs:

• Electricity — a 20-camera system draws ~40W continuously = ~29 kWh/month = ৳290/month (at ৳10/unit). Basement DVR draws another 15W.
• UPS battery replacement — every 2-3 years, ৳3,500-8,000 for basement DVR UPS.
• HDD replacement — surveillance HDDs typically last 3-5 years. ৳6,000-15,000 per drive.
• Camera cleaning/adjustment — quarterly cleaning of outdoor cameras (dust, rain, spiderwebs). ৳500-1,500 per visit.
• Occasional camera replacement — 1-2 cameras per year fail or need lens replacement. ৳3,000-15,000 each.
• AMC contract (optional) — CSL Systems offers ৳15,000-45,000/year AMC for apartment buildings.

Budget: ~৳3,000-8,000/month in ongoing costs for a 20-camera building.

6. Storage retention for apartments

Standard: 30 days minimum, 60 days recommended. Apartment committees often discover incidents 2-3 weeks after they happen (via police report or resident complaint), so 30 days is barely adequate.

Sizing formula: 20 cameras × 4Mbps × 30 days = ~26 TB. Spec 2× 16TB Seagate Skyhawk drives (32TB usable). For 60 days, double to 4× drives.

7. Common apartment CCTV mistakes

• Buying cheapest DVR from local bazaar — no warranty, dies in 6 months, no replacement parts available.
• Underestimating cable runs — 25-storey buildings have 200+ metre runs. Cheap CAT5 = signal loss = camera dropouts.
• Placing NVR in guard room (unlocked) — first thing thieves take. Lock in a secure, non-obvious location.
• No UPS on main NVR — Dhaka power cuts happen daily. Without UPS, footage from load-shed period is lost.
• Cameras pointing at flat entrances — invades resident privacy, generates complaints. Cover corridors from mid-corridor angles, not flat-door angles.
• No plan for lift camera access — lift maintenance company controls lift shaft. Coordinate cabling before installing lift camera.
• Wrong lens choice for parking — narrow lens misses whole parking bay. Use 2.8mm wide angle for basement parking.

8. Legal + committee documentation

Your society should maintain:

• Written CCTV policy signed by committee president
• Physical access log for footage review (who, when, why)
• Data retention policy (30 days general, longer only if incident recorded)
• Written consent from committee for any facial recognition or ANPR features
• Vendor AMC contract (if applicable)
• Building floor plan with camera positions
• Passwords stored securely — not on paper stuck to NVR

9. BDT budget guide (2026)

Turnkey CCTV installation for apartment buildings, including cameras, NVR, storage, PoE switches, CAT6 cabling, UPS, junction boxes, installation, and 1-year on-site warranty:

• 6-storey walk-up (10-14 cameras) — ৳75,000 to ৳1,20,000
• 10-storey mid-rise (16-22 cameras) — ৳1,25,000 to ৳2,00,000
• 15-storey tower (24-32 cameras) — ৳2,10,000 to ৳3,50,000
• 25-storey premium (40-55 cameras with HikCentral) — ৳4,80,000 to ৳8,50,000
• Gated society (80+ cameras with multi-NVR + VMS + ANPR at gates) — ৳12,00,000+

Per-flat cost example (10-storey with 40 flats, ৳1,60,000 total): ৳4,000 one-time per flat — comparable to a single month’s iftar committee contribution.

10. Mobile app access — every committee member

Modern apartment CCTV comes with mobile app remote access:

• Hikvision Hik-Connect or Dahua DMSS — free apps, iOS + Android
• Up to 8-16 committee members can add the DVR/NVR to their phone
• Live view + 30-day playback available from anywhere with internet
• Role-based access — some members full admin, others view-only
• Alerts + notifications for motion in restricted zones (rooftop, generator room)

This transparency reassures residents — anyone on the committee can check footage without going to the guard room.

Frequently asked questions

How many cameras does a typical 10-storey apartment need?

16-22 cameras — 2-3 at main gate + guard room, 1 per lift lobby (10), 1-2 for lift interior, 2 for staircase entry/exit, 3-4 for parking, 1 for rooftop, plus 1-2 for community facilities.

How to get 40 flat owners to agree on CCTV in our building?

Committee presents formal proposal with 3 vendor quotations at owner meeting. Discuss real incident case studies from similar buildings. Vote by 2/3 majority. Written resolution signed. Per-flat cost of ৳3,000-8,000 is typically accepted.

Who pays for CCTV maintenance in apartment?

Society general fund via monthly service charge. Budget ৳3,000-8,000/month ongoing (electricity + occasional camera replacement + HDD/UPS). Consider AMC contract for predictable costs.

Is it legal to install lift camera in Bangladesh?

Yes, with visible signage stating CCTV recording. Lift interior camera helps prevent violence, theft, and harassment. Committee decision, no separate government approval needed.

Should cameras point at individual flat entrances?

No. This is a common privacy complaint. Cameras cover corridors from mid-corridor angles that show general movement but not close-up of individual flat door activity. Individual flat security is the owner’s responsibility.

How much does apartment CCTV cost per flat?

10-storey with 40 flats needing 20-camera system: ~৳1,60,000 turnkey = ৳4,000 per flat one-time. Ongoing: ৳3,000-8,000/month society-wide = ৳75-200 per flat per month.

Can I view apartment CCTV from my phone?

Yes — Hik-Connect (Hikvision) or DMSS (Dahua) free mobile apps allow up to 8-16 committee members to view live cameras + 30-day playback. Password-controlled with role permissions.

What retention is needed for apartment CCTV?

30 days minimum, 60 days recommended. Incidents in apartments often discovered 2-3 weeks late. Storage sized: 20 cameras × 60 days ≈ 50 TB (spec 4× 16TB Skyhawk RAID-1).
