Warehouses and godowns in Bangladesh — from Tejgaon industrial-area distribution centres to the Chittagong port bonded warehouses and BEPZA export godowns — face a specific CCTV problem that retail and office installations do not: large open volumes with weak ambient light, high-value inventory turning over daily, and an industry norm of insider-driven shrinkage. CSL Systems has designed CCTV for logistics customers ranging from Pathao Courier hubs to pharma cold-chain warehouses, and this guide covers the design decisions that separate a working warehouse CCTV from one the auditors reject.
1. The four zones every warehouse CCTV must cover
Zone 1 — Loading dock & shutter gate
The highest-risk camera in any warehouse. Cover the full width of every loading shutter with a 4MP ColorVu bullet, plus a second camera aimed at the truck licence plate. For high-value cargo (electronics, pharma, garments for export), add ANPR at the gate — Hikvision iDS-2CD7A46G0 series reads Bangladesh plates reliably in day and night. Retention 90 days minimum for buyer-audit compliance (Walmart, H&M, Zara supplier audits accept 90-day dock footage as evidence of chain-of-custody).
Zone 2 — Aisle coverage inside the warehouse
Rack-height matters here. Standard rules of thumb:
- Under 4m ceiling — one 4MP dome every 8 metres, mounted at 3.5m aimed downward.
- 4-8m ceiling (typical warehouse) — 6MP or 8MP dome every 12 metres, mounted at ceiling with wide 100° lens.
- Over 8m ceiling (high-bay) — 8MP or 4K bullet every 15 metres, mounted at rack-top level (not ceiling) so face-height is visible.
For dark warehouses with limited fluorescent light, use Dahua WizSense or Hikvision AcuSense with ColorVu — false colour compensation gives you readable footage even under yellow sodium-vapour lighting.
Zone 3 — Picking & packing area
This is where product moves from shelf to shipping box, and where employee pilferage is easiest. Cover each picking bay overhead with a 4MP dome at 2.8mm aimed straight down at the packing table. For high-value pick zones (jewellery, pharma, electronics), add a second angle-camera showing the picker’s face.
Integrate with WMS (warehouse management system) if you have one — Hikvision’s HikCentral supports transaction overlay so each pick event is watermarked into the video.
Zone 4 — Boundary wall & perimeter
Overnight break-ins are the single biggest theft category for Bangladeshi warehouses. Cover the boundary wall with bullet cameras every 25 metres at 6mm focal length, angled to capture the top of the wall and the immediate ground beyond. Add PTZ cameras with auto-tracking and strobe-light deterrence (Hikvision DarkFighter or Dahua TiOC) at corner posts — motion triggers a bright strobe + audio warning that has been documented to abort 70%+ of climbing attempts in trial deployments.
2. Storage sizing
A mid-size 8000 sq ft warehouse with 32 cameras at 4Mbps average, 60-day retention:
32 × 4 × 3600 × 24 × 60 ÷ 8000 = 83 TB. Spec: 6× 16TB Seagate Skyhawk in RAID-5 (80TB usable). For 90-day buyer-audit retention, double to 12× 16TB.
3. Common warehouse installation mistakes
- Ceiling-mounted cameras in high-bay racks — you get overhead views of rack tops, not faces. Rack-top mount at 3-4m works better.
- PoE budget under-spec — 32-camera warehouse with 250W PoE budget starves cameras during monsoon-heated 40°C ambient. Spec 500W+ switch (Mikrotik CRS328-24P-4S at 500W, or dual 24-port Hikvision at 370W each).
- Cheap POE cabling (aluminium-core CAT5e) — 4K cameras throttle to 720p or drop offline at 100m runs. Use genuine CAT6 UTP 23AWG pure copper only.
- No UPS on the NVR rack — power dip during the exact break-in and you have no video. Minimum 1kVA UPS for NVR + PoE switch.
- Ignoring monsoon humidity — non-IP66 domes fog within 6 months in Bangladeshi rainy season. Spec IP66/IP67 for all outdoor and loading-dock cameras.
4. Buyer-audit compliance
Export-oriented warehouses supplying international brands (Walmart, H&M, Zara, Target, Marks & Spencer, Uniqlo) undergo periodic buyer audits including a physical CCTV review. Common requirements:
- 90-day minimum retention (some brands require 180 days for high-risk categories).
- All loading docks covered from at least two angles.
- Exit doors covered with facial-identification capable resolution (4MP+).
- Written CCTV policy with data-access log — who reviewed footage, when, why.
- Documented SOP for footage retention and destruction.
We provide audit-ready policy templates and layout drawings with our warehouse installations at no extra charge.

Frequently asked questions
How many cameras does a 5000 sq ft warehouse in Bangladesh need?
Typically 20-28 cameras — 4-6 at loading dock, 10-14 covering aisles and picking area, 4-6 covering boundary walls, 2 at the main entrance. Exact count depends on rack layout and ceiling height.
Do buyer audits (Walmart, H&M, Zara) require CCTV in warehouses?
Yes — 90-day retention with dock and exit coverage is standard. Some brands require 180 days for high-value categories. Written CCTV policy with access log is also required.
What is the difference between ColorVu and AcuSense for warehouse use?
ColorVu delivers full-colour images at night using a warm-light supplement — better for identifying people and objects in low light. AcuSense uses AI to filter out irrelevant motion (leaves, small animals) reducing false alarms. Most warehouse deployments benefit from both features in the same camera.
How much does a warehouse CCTV system cost in BDT for 20 cameras?
Turnkey 20-camera warehouse system with Hikvision 4MP ColorVu cameras, 16-channel NVR with 30TB storage, PoE switches, CAT6 cabling and UPS runs approximately BDT 1,80,000 to 2,80,000 depending on brand mix and cabling difficulty.
Can I install cameras in outdoor open storage yards?
Yes — use IP67-rated bullet cameras with pole mounts. For yards larger than 30m diameter, add PTZ cameras with auto-tracking at corner poles. Anti-fog and surge-protection accessories are essential for Bangladeshi monsoon conditions.
Do warehouses need CCTV integration with alarm systems?
Recommended. Integrate motion-triggered cameras with siren + strobe outputs so unauthorised entry after hours triggers immediate deterrence. Hikvision and Dahua both support alarm-in/alarm-out integration natively.
