What is BS EN ISO 28520:2012?

BS EN ISO 28520:2012 is a comprehensive technical standard that sets guidelines and requirements for the design, installation, and maintenance of closed-circuit television (CCTV) systems used for surveillance purposes. CCTV systems are widely used in various sectors such as public safety, transportation, retail, and hospitality, and this standard helps ensure their effectiveness and reliability.

Scope and Objectives

The scope of BS EN ISO 28520:2012 covers all aspects related to the use of CCTV systems, including equipment specifications, system architecture, installation practices, and operational procedures. The primary objective of this standard is to provide a framework that promotes consistent performance, quality, and compatibility of CCTV systems across different applications and environments.

Key Requirements

One key requirement of BS EN ISO 28520:2012 is the selection and installation of appropriate cameras. Different types of cameras serve specific purposes, and factors such as resolution, sensitivity, and lens characteristics should be considered when choosing the right camera for a particular surveillance need. Additionally, the standard also specifies guidelines for camera placement, ensuring optimal coverage while minimizing blind spots and obstructions.

Another important requirement outlined in the standard is the storage and retention of footage. BS EN ISO 28520:2012 recommends the use of digital video recorders (DVRs) or network video recorders (NVRs) to capture and store video data. These devices should have sufficient storage capacity and robust security features to prevent unauthorized access or tampering. The standard also provides guidelines on data retention periods, taking into account legal and privacy considerations.

Installation and Maintenance

The installation process for CCTV systems must adhere to specific guidelines outlined in BS EN ISO 28520:2012. These guidelines cover various aspects, including cable routing, power supply requirements, and grounding methods, to ensure optimal system performance and reliability. Regular maintenance and testing of the system are also emphasized to identify and rectify any faults or malfunctions promptly.

Furthermore, the standard highlights the importance of proper documentation and user training. Detailed records of the system design, installation, and maintenance should be maintained for future reference. Training programs should be conducted to educate operators on system operation, maintenance procedures, and privacy regulations.

Conclusion

BS EN ISO 28520:2012 plays a crucial role in establishing best practices for the deployment of CCTV systems. By following the guidelines and requirements set forth by this standard, organizations can enhance the effectiveness and reliability of their surveillance setups while ensuring compliance with legal and privacy regulations. Implementing BS EN ISO 28520:2012 not only helps protect assets and deter security threats but also offers peace of mind to both system operators and end users.
