Analysis of key acceptance factors
Core indicators for construction acceptance
The new standard requires that the installation firmness inspection pass rate of front-end equipment be ≥80%, the lightning protection grounding resistance value be ≤4Ω, and the cable identification completeness rate be 100%. A case study of a local public security bureau shows that the use of intelligent inspection instruments can improve construction acceptance efficiency by 40%...
Required inspection items for technical acceptance
- Cascade function: must comply with GB/T 28181 standard, measured transmission delay ≤2s
- Video storage: minimum storage period of 180 days, support for SVAC/H.265 dual encoding
- Clock synchronization: server deviation ≤1s, acquisition equipment ≤3s
Implementation suggestions
Acceptance preparation stage
- Complete the system trial operation 30 days in advance and record abnormal events
- Prepare 14 types of original acceptance materials (including hidden engineering image materials)
- Configure professional testing equipment such as network analyzer
Common Problem Solving
When the acceptance rate is between 0.6-0.8, it is recommended to: ①Prioritize rectification of Class A mandatory inspection items ②Supplement third-party inspection reports ③Extend the trial operation period by 15 days...
