Parking surveillance requires dedicated LPR cameras (99%+ recognition) at entry/exit, starlight cameras (0.001 lux) inside garage, and 30+ days 24/7 storage. Plan for blind spots from structural columns.
1. Core Requirements
Underground garages have 20-50 lux vs 300-500 offices. Entry/exit suffer black-hole/white-hole effects. Plates captured at angles — standard cameras fail. Columns create blind spots. Full capture-recognize-lift must complete in 200ms.

2. Camera Selection by Zone
Zone-Based Camera Table
Zone | Camera Type | Key Specs |
Entry/Exit Lane | Dedicated LPR Camera | 2MP+, 99%+ recog. |
Entry Panorama | Bullet IP Camera | 2MP, WDR 120dB+ |
Garage Main Lane | Starlight IR Bullet | 0.001 lux, IR 30-50m |
Parking Area | Dome/Mini Bullet | 0.001 lux, 2.8mm wide-angle |
Selection Principles
LPR: sensor+algorithm. Interior: low-light capability. Outdoor: weather protection.

3. LPR/ANPR Technology
How LPR Works
LPR camera: high-res sensor + IR fill light + embedded algorithm. Vehicle triggers loop/radar, on-device plate localization + OCR outputs plate number + time + images.
Parameter | Minimum | Recommended |
Resolution | 2MP | 3-5MP |
Recognition Rate | 99%+ | 99.5%+ |
Capture Speed | 300ms | 200ms |
Waterproof | IP65+ | IP67 |
Installation Angles
Horizontal deviation 15. Vertical tilt 30. Mount height 1.5-2.5m. Trigger 15-25m from camera. Use dedicated LPR cameras, not standard IPC+server software.

4. Low-Light Strategies
Four Strategies
Strategy | Technology | Cost |
1: IR (Basic) | Built-in IR, 20-50m | Low |
2: Starlight | 1/1.8 sensor, 0.001 lux | 2-3x IPC |
3: White Light+Starlight | Warm LED 2700-3500K | +500-1000 CNY/ch |
4: Thermal+Visible | Thermal fusion | 10,000+ CNY/ch |
Deployment Gradient
Residential: IR. Commercial: Starlight. Premium: White Light+Starlight. Note: IR mode cannot capture vehicle color.

5. Barrier Integration
Three Architectures
Option | Scale | Budget |
A: LPR+Controller | 1-3 lanes | 8-15K CNY |
B: LPR+Platform | 3-10 lanes | 30-80K CNY |
C: Cloud Parking | Unlimited | Per lane/month |
Prefer ONVIF Profile G or REST API. Output: plate, color, time, images, confidence. Lift delay 500ms. Local cache for offline.

6. Storage & Bandwidth
Daily storage(GB)=bitrate(Mbps)*3600*24/8/1024. 20 cams, H.265 4Mbps, 30d=25.3TB. Reserve 20%. Surveillance HDDs. Bandwidth=bitrate*cams*1.2. LPR:4Mbps+ for plate detail.
Param | Formula | Example |
Per ch/day | Rate*3600*24/8/1024 | 42.2 GB/day |
Total 30d | Daily*30 | 25.3 TB |
Storage Architecture
Architecture | Scale | Budget |
Single NVR Local | 32 ch | 2-8K CNY |
NVR+Cloud Backup | Unlimited | Per cloud plan |

8. Decision Tree & FAQ
Q: Step 1: Identify Scenario
A: Residential: low-light+scrape evidence. Commercial toll: LPR core. Mall/office: guidance+security. Outdoor: weatherproofing.
Q: Step 2: Technology Path
A: High LPR: dedicated+platform. Dark garage: starlight+fill light. Dense columns: wide-angle dome. Remote: cloud or NVR.
Q: Q1: Night glare solution?
A: Use IR fill light, enable HLC, adjust angle 5-10, use True WDR LPR cameras with dual shutter.

9. Compliance Checklist
- ☐ Post visible surveillance notice at entrance
- ☐ Camera coverage must not intrude private spaces
- ☐ Establish access approval for video retrieval

Target readers: security owners, system integrators, and EHS engineers for petrochemical, oil and gas, pharmaceutical, powder processing, and coal mining sites where explosive gas or combustible dust exists. Core takeaway: a normal camera is itself an ignition source in flammable environments. You must use explosion proof cameras certified to ATEX, IECEx, or China Ex, selected by hazard zone, installed with proper grounding, and documented for compliance. This guide gives a reusable selection, install, and acceptance workflow.

CCTV Maintenance Outsourcing: SLA Tiers, Market Rates, KPI and Contract Playbook
Conclusion first: the real cost of a surveillance system is in its operation. Three years of maintenance typically equals 30% to 50% of the build cost, yet most buyers spend the budget at install and leave operation to whoever happens to notice. Lock the maintenance boundary while signing the build contract. This guide breaks down the in-house versus outsourced decision model, a three-tier SLA (P1 / P2 / P3), per-point market rates and how to read a quote, the two KPIs that decide payment (camera online rate and footage integrity), the five clauses every contract must hold, the 90-day handover that most often loses control, plus a selection checklist and acceptance tests.
