Product Overview

Under the unified framework, Power® Video Networking Platform is designed to provide the cross-network and efficient access, stable storage, effective management and sharing services for videos, images, Wi-Fi, GPS, RFID and other devices or data in public security industry.

Technical Features

1.Fast access architecture for devices - POSA

POSA breaks down the processes of video applications into several standard interface components defined in this Document. When accessing the device, it allocates the same function to the same component according to different interfaces of SDKs. In this way, the uniform interface is output for upper-layer applications, thus achieving the standard interface for services.

2.Isolation of process of components

Varying component processes are activated for SDKs of manufacturers, allowing the normal operation of the devices of other manufacturers in the system in case of issues arising from a SDK of any manufacturer.

3.Multilevel forwarding of videos

Supporting the forwarding of videos across the segments and isolated platforms; supporting the forwarding of stored videos at the front end; supporting the limit of routes on demand; and equipped with the function of link preemption (high-level preemption).

4.Technology of data synchronism

On the Platform where leading technology of data synchronization is employed, all nodes in the system remain high consistence. If a certain node changes its status in a short time, others in the whole system will soon resume synchronization. For instance, in the case of some new cameras furnished to a node, the configuration of new point at this node can lead to the data synchronization of others immediately. Such technology lays the foundation for fully distributed architecture by guaranteeing the status in the whole system is consistent.

5.Redundant trunk routing for fail-safe mechanism

Each central management server is configured with a number of digital trunks. By setting redundant digital trunks, the automatic routing mechanism of trunk can easily locate the redundant media forwarding server and veer the video toward the digital trunk in this server when a media forwarding server fails.

6.Flow forwarding cluster

It boasts the function of flow forwarding cluster with the flow forwarding server which supports high concurrency via stacking. With the features of load balancing and failure redundancy, the cluster forwarding is more reliable and flexible, and can obtain rapid switchover in case of failure.

7.Multi-dimensional big data integration

It supports the access to various resources including videos, vehicle bayonets, face bayonets, Wi-Fi, RFID, GPS, and warning device, the management of million-level resources and concurrent access of multiple users.

Functional Characteristics

Data access and integration

1.Access and integration of video surveillance resources

It integrates the self-built video resources of public security departments, the self-built video resources of social organizations, the security monitoring resources of civil Internet, and the resources of videos captured from mobile devices. The LAN video surveillance resources can be accessed through devices by establishing the video integration platforms in public security information network, the private video network of public security, the outer network of government, Internet and other networks, and integrating the video surveillance resources in varying network environment. The integration of video resources is capable of going beyond the limit of network and ensuring the safety of network backed by the security perimeter platform.

2.Access and integration of image resources

The access and integration of image resources includes the access to images captured by electronic police, bayonets, pan- bayonets, intelligent front-end, face bayonets, and mobile devices. The sources of images support the network segments including the public security information network, the private video network, the outer network of government, and Internet. By configuring the image capture services in these segments, it can gather the image resources at individual segment and then pool all resources via the network security perimeter devices.

3.Access and integration of data resources

The access and integration of data resources refers to a larger number of information capture devices in the construction of a safe city, the text information captured by platform, the real-time push notification, and the collection and pooling of database. Based on the attributes of the data source, it includes real-time data, such as vehicle traffic records, RFID data collection, win data collection, access card data collection, card and certificate data collection; and offline data, log data (some systems do not support data push notification, but can share data collection log) and public security business data (in the information network of public security). The offline data include texts, system logs, database logs, database interfaces, system query interface, and the like.

5.Sharing of resources

The sharing of resources includes the sharing of resources among different police classifications of public security (the private video network and public security information network), governmental departments (the outer network of government), and the public (Internet). The sharing of video image resources calls for meeting the requirements of the security of network and applications: for one, the security specifications of the flowing of network data should be followed, and the resources of public security information network are not allowed to be shared outwards. Some of the resources from the private video network can be shared in the outer network of government and Internet; for another, the sharing of resources is subject to the control of users’ rights.

Real-time video

It supports functions such as real-time preview, multi-screen switching, image capture, electronic amplification, and transcription to the local area;

It supports automatic/manual switching of video definition.

PTZ control

It supports functions including PTZ control, preset position, cruise retrieval, setting and 3D PTZ control;

It supports functions of PTZ locking, unlocking and seizing.

Cascading/interconnection of international standard

It supports interaction and cascading on video monitoring platform based on Security and Protection Video Monitoring Network System Technical Specification for Information Transport, Switch and Control (GB/T28181-2011).

It supports non-standard code stream to convert to standard international code stream; supports functions such as category push, password authentication, category subscription, category inquiry and heartbeat detection; supports functions including selective sharing of resources, review and reception of resources, review and update of resource attribute and removal of redundant resources. 

E-map

The system supports to add online/offline maps and positioning the camera on GIS map; supports to play real-time video on GIS map and conducts video polling. 

Arborescence/stellate networking

The integration of arborescence and stellate models can realize multilevel vertical cascading, horizontal stellate cross-origin resource sharing, best route of video optimization and fully-connected video networking capacity managed and controlled by refined authority. 

Through vertical multi-level cascading of bottom-up networking nodes from county to city to province, it realizes the aggregation and interconnection and intercommunication of video resources and meets the requirements of unified retrieval and management by business department from different levels; through stellate model, it realizes the data sharing of real-time video, meets the requirement of cross-regional data sharing in same level department in different regions; through vertical multi-level and horizontal sharing, it realizes the whole-area covering of video data and whole-network sharing. 

As for same-path video resources, where the resource can be obtained in several paths, based on the video routing table technology, it will choose the best routing path to retrieve the video; where it cannot reach the best routing path, it will automatically switch to the second path to acquire the resource to ensure the usability of the video at all time. In the video data sharing, it can carry out a refined management and control on authority of the video resources in shared output of each path, including the video-on-play/recording playback/PTZ control/ and user management and control, to ensure the control of the whole process in retrieving the system video resources.

User Management

It supports the concentrated control and management of user; supports the concentrated control and management of the subordinate from the superior; supports the management of functions of user creation, access allocation and user block of subordinate users.

It supports the unified management of user access and refined management of user function authority and resource authority. 

It supports video block function. When emergency security/emergency treatment occurs, the administrator can block videos according to users and resources to guarantee that the irrelevant personnel cannot see videos concerning emergencies.

It supports the unified inquiry of user log to inquire user’s operating log.
