FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
rights. IEC shall not be held responsible for identifying any or all such patent rights.

INTRODUCTION
Surveillance systems are important in public safety projects to maintain law and order as well
as public safety, and to assist the police to perform forensic analysis. Due to organizational and
security reasons, large-scale surveillance systems are split in segments, which can lead to
information silos. This document provides a standardized interface for management systems
such that authorized entities can easily access remote information using the same mechanism
they are using today for accessing local information.

4 Overview
4.1 General
IEC 62676-2-31 and IEC 62676-2-32 provide a detailed protocol definition for interacting with
video surveillance devices such as cameras and digital recorders. Similarly, IEC 60839-11-32
and IEC 60839-11-33 describe how to monitor and configure electronic access control systems.
These two parts are based on IEC 60839-11-31, which defines a communication mechanism
based on web services. This document extends IEC 60839-11-31 by adding cloud connectivity
and remote addressing to the framework. Note that this document does not contain any domain-
specific details, since all interfaces defined in the above-mentioned parts are applicable without
any modifications. Therefore, this document covers the integration of a wide range of physical
security systems into any management system. This document describes how a remote client
or management system connects to resources such as cameras. The approach shown here
allows scaling over several hierarchies. The examples in 4.2 show the mechanism principle with
two layers of video surveillance systems (VSS) called "lower level" and "higher level". In this
system, a higher-level VSS can retrieve a resource like device information from a lower-level
VSS, to trigger corresponding actions for different devices that are connected to the lower-level
VSS.
Access to remote VSS can require strict authentication constraints. The related definitions are
outside of the scope of this document.
4.2 Remote access
Figure 1 shows a typical management system topology as deployed for bigger installations. So-
called lower-level video surveillance systems incorporate numerous surveillance cameras and
other equipment to monitor a region of a premises or city district. Higher-level video
management systems allow supervision of large compounds.

SIST EN IEC 62676-2-33:2022
IEC 62676-2-33:2022 © IEC 2022 – 9 –
Figure 1 – Hierarchical system example
In a way similar to the cameras shown in Figure 1, the VSSs expose an interface towards the
higher layer via which a client can access any resource placed below. Typically, the VSS
restricts the access to any of its associated resources depending on the authorization granted
to the client.
Instead of defining a new interface, this document defines a small set of rules explaining how
a VSS has to present resources to a higher-layer entity. Devices implementing IEC 60839-11-31
address resources via tokens for which this document defines a small set of mapping rules. In
the example of Figure 1, both the high-level VSS as well as clients A and B can use exactly the
same interface to control a camera as the lower-level VSS does today.
4.3 Cloud uplink
The IEC 60839-11-31 defines that the client initiates a connection to a device, as depicted in
Figure 2.
Figure 2 – Standard connection initiated from the client
This connection mechanism works very well within standard networks. However, in cases where
the device is located behind a firewall and the client resides in the cloud, the client cannot
establish the connection. In these cases, the device needs to establish the connection. Such a
connection is called "uplink" and needs to be initiated from the device, as depicted in Figure 3.

Figure 3 – Connection initiation from the device
This document specifies a solution that allows a camera or management system to use an
uplink to facilitate existing web server functionality and RTSP server functionality using the
HTTP/2 protocol.
5 Requirements
5.1 General
To achieve the interconnection between High-level VSS (H-VSS) and Low-level VSS (L-VSS),
there are some basic requirements for the system.
5.2 Functional requirements
The detailed functional requirements of the interconnection between H-VSS and L-VSS are
described in two aspects: resource usage and configuration.
For resource usage acquired from L-VSS to H-VSS, the following requirements are described:
a) Live streaming control. Live streaming on demand, supporting on-demand image display,
zoom, capture and recording, and multi-user support for the same image resources on-
demand at the same time.
b) Historical image retrieval and playback. Retrieve historical image data of the device in the
network, according to the specified equipment, channel, time, alarm information, etc.,
playback and download. Playback supports the following methods: normal playback, fast
playback, slow playback, picture pause, image capture and zoom display. The recording
information is in the L-VSS.
c) Remote control. The remote operation of the device can be controlled remotely by manual
or automatic operation, e.g. using pan, tilt or zoom (PTZ) functions. Optionally support
locking to gain exclusive access.
d) Output of the decoded image. Real-time image decode, the output could be displayed.
Remote control of video wall located in L-VSS.
e) Storage management. Hierarchical distributed storage management, combining device
storage and client storage, to support the storage settings of location, time, backup strategy,
finishing strategies, etc.
• Content transfers from L-VSS and H-VSS.
f) Client management. L-VSS s
