Industrial security: IP67 cams, PoE, NVR 30+ days, 3-zone deploy. Budget: small 3K-8K CNY, large 10K-50K. Choose ONVIF brands.
TL;DR: IP67 min, PoE+NVR, 3 zones, 30-day storage, ONVIF.
I. What Does Your Factory Need? (30s)
Answer: (1)Env: ordinary, dusty, hi/lo temp, chemical? (2)Area: <500m2, 500-2000m2, >2000m2? (3)Mgmt: local guard, remote, mobile app?

II. Core Parameters
2.1 IP Rating: IP67 Minimum
Rating | Meaning | Scenario |
IP65 | Dust-tight | Indoor |
IP66 | Strong jets | Wash-down |
IP67 | Short immersion | Outdoor |
IP68 | Continuous | Drainage |
2.2 Explosion-Proof Rating
Rec: indoor IP65, outdoor IP67+. Never use consumer IP54 cams indoors.
2.2 Explosion-Proof Rating
Mark | Environment | Scenario |
Ex d IIC T6 | Gas explosion | Chemical |
Ex tD A21 | Dust explosion | Flour/Wood |
Dual | Gas+dust | Integrated |
2.4 Resolution & Lens Selection
Exp-proof cams MUST have national cert (CNEX/ATEX). Modifying ordinary cams is illegal.
──────────────────────────────────────────────────
III. Three-Zone Deployment
3.1 Production Line Monitoring
Goal: traceability, compliance. Use bullet cams fixed on workstations.
Line Type | Camera | Special |
Electronics | 4MP bullet | ESD-safe |
Machining | 4MP dome | Fluid-resist |
Food | Stainless | Washable |
Chemical | Exp-proof dome | CNEX |
3.2 Warehouse Monitoring
Shelving aisles: bullets at both ends. Loading: dome+bullet. Critical: add thermal cam.
Type | Deploy | Storage |
General | 1 bullet / span | 30d |
Valuable | 1/aisle + exit dome | 90d |
Cold | Heated bullet | 30d |
Hazmat | Exp-proof+thermal | 90d+ |
3.3 Perimeter Security
Perimeter: IR bullet (>=50m night) + AI human/vehicle classification.

IV. Network and Power
4.1 PoE vs Independent Power
Solution | Pros | Cons | Suitable |
PoE | Single cable | <=100m | Most |
DC | No limit | Complex | Supplementary |
PoE extender | To 250m | Extra device | Long dist. |
Fiber | Unlimited | High cost | Large |
4.2 Network Architecture
Isolate surveillance network from office. Use VPN/P2P for remote access; NEVER expose cams to internet.
──────────────────────────────────────────────────
V. Storage
5.1 Capacity
Cams | Resolution | Bitrate | 30-day |
8 | 1080p | 2Mbps | ~5TB |
16 | 4MP | 4Mbps | ~20TB |
32 | 4MP | 4Mbps | ~40TB |
Formula: (bitrate/8) x 3600 x 24 x days x cams = bytes.
5.2 Methods
Method | Pros | Cons | Rec. |
NVR internal | Plug-play | Single fail | Small |
RAID NVR | Redundancy | Costly | Critical |
Cloud | Off-site | Bandwidth | Supplementary |
ONVIF essential for multi-brand flexibility.

VI. Camera Selection Quick Guide
Choose by scenario:
Scenario | Recommended | Reason |
<500m2 warehouse | 4x1080p PoE+4ch NVR | Economic |
Medium shop | 8x4MP PoE+8ch NVR | Balanced |
Large campus | 32x4MP+RAID+fibre | Scalable |
Hazmat warehouse | Exp-proof+thermal | Compliance |
VI.2 Price Reference (CNY)
Component | Entry | Mid | High |
1080p bullet | 200 | 400 | 800 |
4MP bullet | 350 | 600 | 1200 |
Dome | 500 | 900 | 2000 |
NVR 8ch | 800 | 1500 | 3000 |
HDD 4TB | 600 | - | - |
──────────────────────────────────────────────────
VII. Compliance and Standards
Comply with GB 50348 (China), IEC 62676 (international), ONVIF Profile S/T. Exp-proof devices need valid certification.
──────────────────────────────────────────────────
VIII. FAQ
Q: How many cams for 1000m2 warehouse?
A: Typically 6-10: 4 aisles, 2 loading, 2 perimeter.
Q: Can I reuse existing cams?
A: Yes if ONVIF. Otherwise use hybrid NVR for analog+IP.
Q: How long keep footage?
A: 30 days min; 90 days for hazmat/high-value.
Q: Need separate monitor?
A: Recommended. 27-inch monitor improves situational awareness.
Q: Internet speed for remote view?
A: 2Mbps upload per 1080p stream. 16 cams: 32Mbps upload.
Q: Are thermal cams worth it?
A: For fire prevention in critical warehouses: yes.
