Introduction
Analysis of the core content of the standard
This standard specifies the test framework for IPC, DVR/NVR, platforms and other equipment in the public security video surveillance networking system, including 7 categories of test environment requirements and 12 core test items.
| Test dimensions | Equipment class | Platform class | Gateway class |
|---|---|---|---|
| Required test items | Registration/deregistration, real-time on-demand | Uplink and downlink test, directory subscription | Protocol conversion, address translation |
| Test tools | Test system + network analyzer | Standard equipment + protocol analysis software | Dual test system networking |
Key technical requirements
Test environment construction
- Equipment test environment: It is required to configure the test system, standard IPC and network protocol analysis tools
- Platform test environment: It is required to deploy dual test systems to simulate the upper and lower platforms
Core test items
- Registration and deregistration test: Verify the device heartbeat mechanism (default 60 seconds interval)
- Audio and video transmission test: Check whether the RTP/RTCP stream complies with the media format in Appendix C
- Alarm event test: Verify that the alarm information XML format complies with the requirements of Appendix A.2.5b
Implementation suggestions
Key points for project acceptance
It is recommended to sample according to GB/T2828.1-2012: full inspection for ≤3 units of the same model, sampling according to AQL for >3 units. Key detection:
- Device registration success rate (required ≥99%)
- Key frame response time (＜200ms)
- Historical video retrieval integrity
Common problem handling
Typical problem solutions:
| Problem phenomenon | Troubleshooting steps | Solutions |
|---|---|---|
| Registration failure | 1. Check SIP message header 2. Verify device ID encoding rules | Confirm that it complies with the encoding specifications of Appendix D of GB/T28181 |
| Video freeze | 1. Capture packets and analyze packet loss rate 2. Check timestamp continuity | Adjust MTU value or enable TCP transmission |
Standard Evolution Analysis
Main enhancements compared to the 2016 version of the standard:
- Added Internet Gateway test item (Chapter 6.3)
- Refine platform cascade test scenarios (Clause 5.1.5)
- Supplement H.265 encoding test requirements (Appendix C.2.2)
