As the video monitor system of city network needs large investment and complicated techniques,
so an object general evaluation is very important before its construction. The basic features of a
video monitor system are large investment, technological demanding, a large number of users
and links involved which include image collection, transmission, storage, management and
share.
Technologically, there are the following standards to judge whether a video monitor system
functions well or not. First is its practicability, as a good system, some factors such as the local
environment conditions, supervising objects, ways of monitoring and maintenance must be taken
into consideration so that the normal running of the system can be insured and the demands of
the public security management can be met as well. Then is its reliability and stability; adopted
the advanced skills and reliable equipment, software of the system has functions of maintaining
and recovering so that a relatively long run time can be insured and a quick recovery will also be
available when mistakes happened.
Whether it is convenient to update and maintain or not is a big issue, too. Software of a system
should equipped with the function of automatic updating due to the large scale of the system.
Besides, the warning system is consisted of many complex systems including the network,
storage and operation system, terminal equipment. Therefore, it is for every subsystem has the
function of recording of what happened. Last is the compatibility and the extent of
standardization. Compatibility is the key for devices of different companies and protocols to
interact well. A good system can communicate and share data efficiently, and implement
compatibility and inter operating among devices. Furthermore, the higher extent and the better
openness of a system, the longer the life circle it will have.
