Many domains sustaining a fast expanding market
Sports events that attract large crowds represent a particularly sensitive challenge for organizers and require exceptional security measures, many of a technical nature.
In addition to sports venues, businesses and homes demand more security and access limited to authorized individuals only. The market for alarm and electronic security systems will continue to expand in coming years, fed by a quest for increased safety and security, constant concern over terrorism and crime as well as the need to protect critical infrastructure. IEC TC 79 develops International Standards for alarm and electronic security for a wide range of applications, including new ones like medical and social alarm systems, which are driven by the needs of an ageing population.
Wide scope and multiple systems
IEC TC 79 remit is to prepare International Standards for systems for "the protection of buildings, persons, areas and properties against fraudulent actions having the purpose to enter in a place or to take or to use something without permission and other threat related to persons".
The wide range of applications and needs of the sector mean many different systems are in deployment. TC 79 work does not cover the production of Standards for fire detection and fire alarm systems in general, but does include the following:
- Access control systems
- Alarm transmission systems
- Video surveillance systems (VSS), also known as closed-circuit television (CCTV)
- Combined and/or integrated systems, even those that include fire alarm systems
- Intruder and hold-up alarm systems
- Remote receiving and/or surveillance centres
- Social alarm systems
These systems can be operated by ordinary or trained persons to provide a local or remote alarm. They can be used for calling private guards, social assistance, emergency services or the police, and for recording and transmitting information (dated or undated), sounds and pictures of places and people for surveillance purposes.
Alarm systems have been used for decades as deterrents against theft and hold-up and for fire detection and evacuation warning purposes. However, owing to emerging requirements, such as better perimeter intrusion prevention to protect critical infrastructure and the needs of an ageing population, and to technological advances in electronic components they have expanded to other fields. As a result they have also become popular in the field of access control, video surveillance, and medical and social alarm systems.
This has led TC 79 to create three Working Groups (WGs): WG 11: Electronic access control systems, WG 12: Video Surveillance Systems (VSS), and WG 13: General requirements for building intercom systems.
In addition to traditional markets such as in sports installations, businesses or government buildings, the expansion of access control and video surveillance systems is a consequence of an increasing need for more safety and security in residential places such as homes, hotels, hospitals and schools.
The other domain in which there is steady growth is that of medical and social alarm systems and services, which allow, for instance, elderly or disabled residents in specially equipped accommodation and dwellings to activate an alarm and call for assistance in the event of an emergency (domestic accident, health problem or other issue).
Greater impact of IT systems
Information technology has had a major impact on alarm systems, making it easier, cheaper and faster than ever before to transmit and record information or data, including sending sounds, pictures and video through communication systems from the premises being monitored to an alarm receiving centre. Reporting system faults and remote correction of such faults has also become easier.
Modern alarm systems no longer rely solely on the public switched telephone network (PSTN) to transmit signals, but increasingly on other networks too: the Internet, cable TV distribution systems, cellular phone networks or other radio systems.
Customers not only expect a reliable system but also want an appropriate answer and/or service to follow the alarm immediately. This has several consequences for alarm and surveillance systems.
A modern system must be able to transmit the alarm through a reliable communication channel. The consequence of the shift of communication from the PSTN to other networks is a need for standardized transmitting procedures and communication protocols between the components installed both in the place under surveillance and those in the alarm receiving centre.
The alarm receiving and/or surveillance centre should be able to verify and record the alarm, monitor the communication and control the local equipment.
Reliability is essential
Manufacturers, certification bodies, users, etc. should benefit from Standards dealing with access control, VSS communication and protocols. Standard communication procedures between the local alarm system and the receiving centre are also necessary. It is obviously important to have reliable detection systems and transmission channels as alarms are meant to protect lives as well as property.
Although these systems are based on sophisticated electronic design, they differ from other electronic systems in their requirement to be able to work reliably in case of emergency.
Electromagnetic compatibility (EMC) requirements in the field of alarm systems are also extremely important from the point of view of reliability. For example, some components used in alarm systems may behave as antennas, either influencing their environment or being themselves influenced by electromagnetic fields. TC 79 prepares International Standards on EMC immunity requirements for components of fire and security alarm systems.
Widespread agenda and cooperative approach
The complexity of modern alarm and detection systems and the wide range and nature of the components they include, such as infrared, microwave and ultrasonic or glass break detectors and transmitters, mean they rely on many Standards to operate and communicate signals and orders. IEC TC 79 work on these Standards involves liaisons with other IEC TCs, like IEC TC 9: Electrical equipment and systems for railways.
TC 79 works with the other two global standardization organizations, the International Organization for Standardization (ISO) and the International Telecommunication Union (ITU), both of which are active in some aspects of standardization for alarm and electronic security systems. This work is carried out within ISO/IEC/ITU-T SAG-S (Strategic Advisory Group on Security), which oversees standardization activities relevant to the field of security.
It also liaises with other bodies, such as the Open Network Interface Forum (ONVIF), is a global and open industry forum with the goal to facilitate the development and use of a global open standard for the interface of physical IP-based security products, and the Physical Security Interoperability Alliance (PSIA) to avoid standards overlapping and being duplicated.
TC standardization work will underpin dynamic market
IEC TC 79 was setup in May1979, but was inactive from June 2001, due to lack of experts, before being reactivated in September 2007. Some 125 experts take part in its standardization work. As of June 2016, it had issued more than 50 publications. 43 are currently available and 10 were withdrawn in 2011; 31 of the publications are recent, having been published since 2010. The Standards include hardware components, interfaces and communication protocols for voice, data and other signals.
Series of TC 79 Standards cover three main domains:
- Intrusion and hold-up systems with the IEC 62642 series currently comprising 15 active publications
- General and specific requirements, and message formats and protocols for alarm and electronic security systems, and for alarm systems, covered by the IEC 60839, series that includes 16 active publications at this time
- Video surveillance systems for use in security applications, with, at present, seven active Standards in the IEC 62676 series (all post 2013)
Growing security concerns in many countries, an ageing population and more accessible, better performing and cheaper alarm and electronic security systems now being installed in private homes and residential buildings, are indicative of a vibrant market. This market, worth some USD 46 billion in 2015, is projected to grow at a compound annual growth rate of 14% over the 2016-2020 period to exceed USD 80 billion, according to US-based research company Global Industry Analysts, Inc. (GIA). IEC TC 79 standardization work will support this growth.
