NSI Technical Bulletin No. 0029 provides guidance on the application of BS 8418:2015, which outlines the installation and remote monitoring of detector-activated CCTV systems. The bulletin highlights significant changes from the previous standard, including terminology updates, the introduction of new compliance requirements, and the consolidation of fault detection and tamper indication protocols. Compliance with the new standard is mandatory for organizations seeking NSI approval, and the document emphasizes the importance of collaboration between CCTV companies, customers, and remote video response centers (RVRCs) in meeting these updated requirements. Manual review is recommended for complete details.
