Why a Dedicated Warehouse Surveillance Plan Matters
Warehouse theft, inventory mis‑placement, and safety incidents cost Indian logistics firms an average of ₹3.2 crore per year. A calibrated CCTV system reduces loss by up to 45 % when cameras are positioned for full coverage, storage is sized for forensic review, and lenses tolerate dust and low‑light conditions typical of high‑bay racking.
1. Camera Placement Blueprint
Perimeter – 360° Threat Envelope
- North‑South walls: Install 4‑MP bullet cameras at 8‑10 m height, angled 30° downward to capture the full fence line and any breach attempts.
- Corner blind spots: Use PTZ units (Hikvision DS‑2DE4A425IW‑DE) with 25× optical zoom to sweep both adjoining walls.
- Gate & guardhouse: Dual‑lens dome cameras (CP Plus 4‑MP) provide facial detail and vehicle plate capture.
Loading Dock – Motion‑Critical Zones
- Place a 6‑MP bullet camera 6 m above the dock floor, covering the truck entry lane and the pallet‑stacking area.
- Install a 4‑MP fisheye dome at the dock ceiling to eliminate blind spots between pallets.
- Deploy a low‑profile infrared PTZ (Dahua SD59230U‑HX) to follow forklift traffic during night shifts.
High‑Bay Racking – Dust‑Proof Low‑Lux Lenses
- Choose lenses with an IP66 rating and a minimum lux rating of 0.05 Lux (color) / 0.01 Lux (IR) for 12‑m tall aisles.
- Mount cameras on the topmost beam, angled 15° downward to capture the full rack height without glare from overhead lighting.
- Prefer varifocal lenses (2.8‑12 mm) to fine‑tune field‑of‑view per aisle width.
2. NVR Storage Sizing – From 30 to 90 Days Retention
All calculations assume H.265 (HEVC) compression, 30 fps, and continuous recording. Adjust the bitrate if motion‑triggered recording is preferred.
| Camera Resolution | Average Bitrate (Mbps) | Storage per Day (GB) | 30‑Day Total (TB) | 90‑Day Total (TB) |
|---|---|---|---|---|
| 4‑MP (2560×1440) | 3.5 | 36 | 1.08 | 3.24 |
| 6‑MP (3072×1728) | 5.2 | 54 | 1.62 | 4.86 |
| 8‑MP (3840×2160) | 7.8 | 81 | 2.43 | 7.29 |
For a typical 32‑camera warehouse (mix of 4‑MP and 6‑MP units) the 30‑day storage requirement is roughly 45 TB. KAS Info Tech recommends a RAID‑6 NVR chassis (e.g., Hikvision DS‑NVR6088‑16S) populated with 12 TB SAS drives, delivering 72 TB usable capacity and built‑in redundancy.
- Calculate total daily bandwidth: sum of average bitrates × number of cameras.
- Multiply by 86,400 seconds, divide by 8 to convert to GB.
- Apply a 20 % safety margin for peak traffic (e.g., forklift headlights).
- Select drives with MTBF > 2 million hours for 24/7 operation.
3. Dust & Low‑Light Engineering Considerations
High‑bay warehouses generate particulate matter that settles on lens surfaces. A regular cleaning schedule (weekly) combined with anti‑dust filters (IP66) extends camera life by 30 %.
- Lens coating: Use anti‑reflective, hydrophobic glass to maintain clarity.
- IR illumination: Deploy 940 nm IR LEDs with a minimum output of 150 mW per camera for color‑less night vision that does not interfere with human workers.
- Power backup: Solar‑assisted 4G cameras (₹5,200 each) are viable for remote dock areas lacking reliable power.
For dusty zones, KAS Info Tech’s Blinkit fulfillment center installed dual‑lens 4‑MP IP66 cameras with built‑in de‑‑fogging heaters (₹6,800 per unit). The solution reduced lens‑obscuration incidents from 12 % to <1 % over six months.
4. Procurement Checklist for Rajasthan & Pan‑India Warehouses
- Define coverage zones: perimeter, dock, high‑bay aisles.
- Select camera models with IP66 rating, appropriate lux rating, and H.265 codec.
- Calculate total bitrate and storage using the table above.
- Choose NVR chassis with RAID‑6 and at least 20 % excess capacity.
- Plan power distribution: PoE switches (Cisco Catalyst 2960‑48LP) for wired cameras; solar‑4G for off‑grid spots.
- Include 24/7 support contract (KAS Info Tech’s ISO 9001:2015 AMC) – ₹1,200 per camera per year.
- Schedule on‑site survey with KAS Info Tech’s engineering team (call +91 80581 22233).
5. Real‑World Deployment Highlights
Blinkit Dark‑Store (Alwar): 48 cameras (4‑MP IP66) covering 12,000 sq m. Storage configured for 60 days (≈ 90 TB). Implementation completed in 4 weeks, ROI realized in 8 months through loss reduction.
DMart Warehouse (Jaipur): 36 cameras (6‑MP) with dual‑lens high‑bay units. Storage sized for 90 days (≈ 7 TB). Integrated with existing ERP for event‑triggered alerts, cutting inventory discrepancy by 22 %.
Conclusion
Effective warehouse surveillance hinges on three engineered pillars: precise camera placement, right‑sized H.265 storage, and lenses that survive dust and low‑light environments. Leveraging KAS Info Tech’s certified OEM partners (Hikvision, CP Plus, Dahua, Cisco) and its ISO 9001:2015 processes guarantees compliance, reliability, and measurable ROI.
