Introduction

Analysis of the core content of the standard

Technical module	Core requirements	Test indicators
Audio and video storage function	9 basic functions such as retrieval/playback/download/lock	Functional completeness, response time
Resource pool management	RAID redundancy, capacity expansion, and support for multiple storage methods	Capacity expansion does not affect business and data recovery capabilities
Interface specification	Complies with GB/T 28181-2022 signaling interaction	Protocol compliance, concurrent processing capability

Detailed explanation of key technical requirements

1. Storage architecture design

The standard requires the use of the SIP protocol architecture to achieve interaction with the central signaling control server:

• The registration type code must be 210 (media storage server)
• Supports two recording modes: streaming media forwarding and direct storage
• The heartbeat interval does not exceed 60 seconds

2. Data security system

Typical application scenario: A city’s public security video cloud platform uses the GB 35114-2017 encryption algorithm to achieve encryption of stored data throughout its life cycle, and ensures data security through regular integrity checks.
