Technical Code for Project of Civil Closed
Circuit Monitoring Television System
Issued on: AUGUST 26, 2011
Implemented on: JUNE 1, 2012
Jointly Issued by the Ministry of Housing and Urban-Rural Development
(MOHURD) and the General Administration of Quality
Supervision, Inspection and Quarantine (AQSIQ) of the
People's Republic of China
Foreword
According to the requirements of Documents Jian Biao [2006] No. 77 issued by the
former Ministry of Construction - "Notice on Issuing the Development and Revision Plan of
National engineering Construction Standards in 2006 (the first batch) ", this standard is
revised from the former standard "Technical Code for Requantation of Civil Closed Circuit
Monitoring TV System" GB/T 50198-1994 by Wuhan Bureau of Broadcast and Television
jointly with all the organizations concerned.
During the revision process of this code, the drafting group conducted extensive
investigation, summarized the practical implementation experience of the former code,
adopted the latest digital technology achievements, conducted tests repeatedly, and
extensively asked for the advice of relevant experts and departments, and finalized it upon
review.
Main revised contents. digital system is added on the basis of the former analog system,
including video compression coded format, network transmission, system bandwidth, storage
and intellectualization, etc.; terms are added; system composition figures, the peak signal to
noise ratio corresponding to the subjective quality of image is obtained through subjective
assessment test; functionality inspection is added for the acceptance part; the optimal
monitoring scope for panel monitors are added.
This code comprises five Chapters and two appendixes, with the main contents as
follows. General Provisions, Terms, Project Design of System, Project Construction of
System and Project Acceptance of System.
The provisions printed in bold type are compulsory ones and must be enforced strictly.
Ministry of Housing and Urban-rural Development is in charge of the administration of
this code and the explanation of the compulsory provisions, State Administration of Radio,
Film and Television is responsible for the routine management and Wuhan Bureau of
