Industry basics | IPC | IPC is the abbreviation for IP Camera. |
| NVR | NVR is the abbreviation for Network Video Recorder. It connects to IPC cameras and primarily provides data storage, video retrieval, and forwarding features. |
| video channel | The physical location on an IPC or NVR device where video signals are input.Generally, an IPC has one or more video channels, and an NVR has multiple video channels. |
| Traffic | One of the measurement dimensions of network consumption. When this product is used, the unit conversion base for traffic is 1024. |
| Bandwidth | One of the measurement dimensions of network consumption. When this product is used, the unit conversion base for bandwidth is 1000. |
| Concurrent playback | Refers to the number of concurrent streams pulled from devices. For example, viewing the feeds of four devices simultaneously is called 4-channel concurrent playback, and if one device is played in four windows at the same time, it is also called 4-channel concurrent playback. The number of concurrent playback channels affects downstream network consumption. |
| View hot and cold storage | The product provides highly reliable and highly available storage services, which are divided into two types. The unit conversion base for storage capacity is 1024. View hot storage: a hot data storage type that can be accessed and retrieved at any time. View cold storage: a cold data storage type suitable for long-term backup and infrequent retrieval scenarios, with a minimum storage period of 60 days. If retrieval is required, the data must first be restored to hot storage. |
Protocol-related | GB/T 28181 protocol | The full name is GB/T 28181, "Technical Requirements for Information Transmission, Switching, and Control of Security and Protection Video Surveillance Networking Systems." It was proposed by the Science and Technology Information Bureau of the Ministry of Public Security and specifies the basic requirements and security requirements for the interconnection structure, transmission, switching, and control of public security video surveillance networking systems.The latest version is the national standard GB/T 28181-2016. |
| National standard code | The GB28181 coding rule consists of four code segments totaling 20 decimal digits: central code (8 digits), industry code (2 digits), type code (3 digits), and serial number (7 digits).When the product is used, our platform generates a 20-digit GB28181 code ID for each device in strict accordance with the national standard and ensures global uniqueness of the ID. |
| RTMP protocol | It is the abbreviation for Real-Time Messaging Protocol, an application-layer protocol family based on TCP that addresses the Multiplexing and packetizing of multimedia data streams. It supports H.264 video encoding, AAC, and MP3 audio encoding. |
| HTTP-FLV protocol | A streaming media transmission method that encapsulates audio and video data in the FLV file format (short for FLASH VIDEO, characterized by extremely small file sizes and fast loading speeds) and then transmits the FLV-format data encapsulated in the HTTP protocol. It supports H.264 video encoding, AAC, and MP3 audio encoding. |
| HLS protocol | The HLS (HTTP Live Streaming) protocol is an adaptive bitrate streaming technology, mainly used for audio and video services on PC and Apple terminals. It includes an m3u8 index file, TS media segment files, and a key encryption string file. It supports H.264 video encoding, AAC, MP3, and AC-3 audio encoding formats. |
| Push streaming URL | Applicable to devices connected through the RTMP protocol. The platform generates a push streaming URL that must be configured on the device. The complete push streaming URL format is rtmp://{domain name}/{appname}/{streamname}, where appname defaults to live and streamname is the device ID. |
| Stream playback URL | The platform generates live/historical stream playback URLs of different protocols for each video channel, which can be integrated into other clients or browsers for playback. |
Product-related | Domain Mame | Domain Name is the name of a computer or a group of computers on the Internet, consisting of a string of names separated by dots. When using the product, you must provide a domain name that has completed ICP filing and Ministry of Public Security filing in the Chinese mainland, so that a video stream playback URL can be generated later. |
| CNAME domain resolution | It is an alias record, used to point a domain name to another domain name, which is then resolved to an IP address (domain name resolution is performed by the DNS server). |
| SSL digital certificate | It is a method of providing online identity verification and a certificate used to represent and prove the digital information of both parties. Websites using SSL Certificates can enable HTTPS encrypted access to ensure the security of transmitted data. The types include DV certificates (domain-validated certificates), OV certificates (organization-validated certificates), and EV certificates (extended validation certificates). |
| Service node | Region where the ISS service is deployed. |
| On-demand stream pulling | To reduce network consumption for users, the platform uses an on-demand stream pulling mechanism during live streaming. Streams are pulled to the cloud only when a video channel is clicked for playback, and stream pulling stops automatically when the player is closed. |
