In many current industry projects, customers use the GB/28181 platform of monitoring platforms such as Hikvision and Dahua, or other third-party GB/28181 platforms. But for those individual soldier terminals that do not have the GB/28181 protocol, how to access the GB/28181 platform network?
First, let’s understand GB/T28181:
The full name of the national standard GB/T28181 protocol is "Technical Requirements for Information Transmission, Exchange and Control of Security Video Surveillance Networking Systems". It is a white paper that defines video network transmission and equipment control standards. It was proposed by the Science and Technology Information Technology Bureau of the Ministry of Public Security. The standard stipulates urban The interconnection structure and communication protocol structure of information transmission, exchange, and control in the monitoring and alarm network system, the basic requirements and security requirements for transmission, exchange, and control, as well as technical requirements for control, transmission processes, and protocol interfaces. It solves the problems of video interconnection, data sharing, and device control. This problem solves the problem of separate video information from the top level and opens up the information island of video networking.
The implementation of the GB/28181 protocol is divided into two parts, one is the signaling part and the other is the streaming media data transmission. Compared with RTMP, GB/28181 supports TCP and UDP modes. The signaling stream is responsible for session interaction and the data stream is responsible for data transmission. It is suitable for platform-level product docking with standard protocol specifications.
GB/28181 is increasingly used in terminals, but generally many terminal manufacturers do not have professional GB/28181 developers, and they need to do compatibility development and docking debugging work with various manufacturers, or modify some customized functions. Without professional developer support, it is difficult to add to the GB/28181 network protocol.
Recently, the Huamai Zhilian R&D team successfully developed the GB28181 SDK and DEMO based on the Android system, a complete GB28181 platform Android client SDK that supports G711A, G711U, AAC audio encoding, and supports H264 and H265 hardware encoding. As a subordinate, it supports GB/T28181-2011 and GB/T28181-2016 versions. It supports Kirin operating system and is compatible with the upper-level platforms of most mainstream manufacturers currently on the market (such as Hikvision, Dahua, Huawei, Uniview, etc.).
Feature list:
• Support video surveillance
• Support national standard intercom
• Support alarm
• Support reporting GPS
• Support TCP/UDP registration
• Support status query
• Support location subscription, directory subscription
• Support TCP streaming
• Support UDP streaming
• Support custom video watermarks
• Audio supports PCMU, PCMA, AAC
• Video supports H264, H265
Huamai Zhilian’s own cloud cluster APP and smart law enforcement APP have GB/28181 modules. The APP is registered to the GB/28181 platform through the GB/28181 protocol. The monitoring platform or other third-party GB platform implementations can be monitored through the GB/28181 platform. APP audio and video capabilities.
In addition, if the third-party application APP itself does not have a GB/28181 module, it can use the GB/28181 SDK provided by Huamai to efficiently develop an APP with GB/28181 audio and video capabilities. The third-party application APP is registered to GB through the GB/28181 protocol. /28181 platform, so that the monitoring platform or other third-party GB platform can monitor the APP audio and video through the GB/28181 platform.
In addition to supporting regular audio and video data access, Android terminals can also support Subscribe real-time location (MobilePosition), real-time directory query, voice broadcast, voice intercom, remote restart, etc., and support standard 28181 service docking. Android terminals that do not have national standard audio and video capabilities can be registered and accessed the existing GB/T28181-2016 services through the platform, which can be used for intelligent monitoring, smart retail, smart education, remote office, production transportation, smart transportation, vehicle or Scenes such as law enforcement recorders.
Using GB/28181 SDK has the following advantages:
1. Reduce development costs
GB/28181 SDK provides a series of tools and code libraries, allowing developers to develop software more efficiently, greatly reducing development costs and time.
2. Improve code quality
GB/28181 SDK provides standard APIs and protocols, allowing developers to write high-quality code. In addition, the SDK provides debuggers and simulators to help developers find and solve bugs in time.
3. Improve software reliability
GB/28181 SDK ensures that developers’ software is compatible with other systems and applications, improving software reliability and stability.
Therefore, even if there are no R&D personnel specialized in GB/28181, terminal manufacturers can use the GB/28181 Android SDK provided by Huamai to quickly develop GB/28181 APP and install the GB/28181 client software on various Android terminals. , you can access the GB/28181 platform to realize the ability to monitor the audio and video of third-party Android terminals with monitoring platforms from manufacturers such as Hikvision, Dahua, and Uniview, or other third-party GB platforms.
