The second generation of digital-analogue combined monitoring, China's production, integration, and manufacturing capabilities lead the world, but the lack of core technologies; this program requires audio and video codec algorithms and chip technology, if not a breakthrough, will restrict the industry's development of;
In the era of third-generation network video surveillance, China is close to or ahead of the world and has a lot of experience in large-scale monitoring platforms and applications. In particular, the introduction of the S-Code algorithm, a security-proof video surveillance digital audio/video codec standard suitable for security applications. It played a key role in China's lack of freedom from core technologies;
The fourth-generation all-IP monitoring solution provides a huge market opportunity and may establish a world-class leading level; if Chinese chip companies can successfully use this market opportunity to promote the use of monitoring core chips and monitoring platforms with independent intellectual property rights, they will Is the domestic security industry can establish the key to the success or failure of long-term competitiveness.
In short, if security companies want to make a difference, they should tap the potential of the security industry mainly from several segments such as safe and smart cities, industrial applications, and civilian markets. At present, Hikvision and Dahua, the leading domestic companies that have successfully entered the front-end camera market, have long-term plans for security operations. For example, Hikvision conducted a series of merger and acquisition integration last year; Security qualification. These measures will enable the company's overall strength to be further enhanced. In the future, companies will only be able to identify their own development direction and become bigger and stronger in the subdivided field, so as to be invincible in the fierce market competition.

Site Selection for Mass Flow Meter Installation
a) Sensor stays away from mechanical vibration source, for example, pump. Use flexible pipe to connect meter with pipeline if inevitable. The housing of meter must be standalone, out of touch with any other device. There must be 3 times the size of sensor between 2 sensors if there are many flow meters on the same pipeline, to avoid resonance.
b) Do not install sensor on pipeline that easily expands with hot and contracts with cold, especially near expansion joint, which leads to a worse stability.
c) Sensor stays away from industrial electromagnetic field, such as large generator and transformer, better 5m at least. Such device influences the performance of drive coil and pickoffs. Make sure magnetic field intensity less than 400A/m.
d) Sensor shall be installed on lower pipeline, to be easily full of fluid.
e) Make sure Ex-mark meet application requirements if in hazardous area.
f) Build a sunshade if the meter is under direct solar radiation. g) Keep the meter from corrosive liquid.
