In the last 15 years, the increasing number of Chinese surveillance cameras is most in the world.
Depends on the data from IDC Markit.
In 2018, China has over 200 million cameras.
And Public security has the most among the ministries, which number is 20 million.
Safety City Project leading by it, is the most potent
developing force for the surveillance industry.
'Opinions on building safety society' published by CCCPC 'Central Committee of the Communist Party of China' in 2005.
Can regard as the first proclamation about this. And The central part of this massive project is the surveillance system.
As the critical department above all.
Public security started two pilot projects in 2003,
named Scientific-Strengthening Police, and
three triple one program. Both emphasized 
the surveillance cameras as the core goal.
By the success of these Pilot projects, many
more regional similar plans had put into force quickly,
and even spread to the remote areas,
in the last all over the whole country.
For quest how this extensive system work? I studied
some relevant documents, such as Authority-opinions by CCCPC,
the GB construction standard for
it, and one research report for Wuhan's monitor system.
From these files, I could detect the
governmental emphasis on it. In China, this system has another Cyberpunk name,
the SKYNET PROJECT.  One standard system consists of four essential parts,
video recording, net transmission,
data storage, and picture analysis.
In these files the unit for the one complete system
is ROAD. And the minimum budget for each ROAD
is 6 to 7 thousand dollars.
The first step is allocating the cameras.
They have two categories, the First Monitoring
Sites and the Second. The First sets in road,
square, and traffic stations, which has vast
people flow. The Second set in the critical
communal sites. Such as the hospital, school,
park, and scenic spots.
In Shanghai, there were 100,000 First and
300,000 Second kind surveillance sites as
one investigation till 2017 by IHS. The first
kind sites need the HD camera operating by
the Security Public in 24 hours. The second-sites
use cameras with only half-price and controlled
by the other relevant departments.
The cameras can also divide into two categories
by appearance: the Gun style and globose style.
The gun-cameras always set at permanent positions,
such as indoor places, meeting room or some
passageway. The advantage of the Globose is
rotating the entire circle. And it often uses
in open area that tour-monitoring according
to a specific time.
Every camera makes massive video data every
day. How to fast transmitting the data with
high quality? The key is reducing the time
delay. Using an optical transceiver has become
a mainstream solution. In this way, the total
delay time can decrease to just 2 seconds,
from the camera to the recording device.
The data recording method is relatively easy,
only needing ordinary hard disk or use DVR.
One HD camera generates 0.25 mega Bytes every
second and work for 24 hours. Then multiple
the minimum saving days 15, the capacity-requirement
for this camera is 316 Giga Bytes. One hard
disk with 3000 Tera Bytes can serve 10 thousand
regular cameras.
As mentioned above, one complete system has
various and costly devices. Here's one video
monitoring project's contract for the Beijing
Daxing International Airport. I found 28 items
on the purchase list, the total price is 1
million dollars, and just for the cargo area.
These complicated frameworks result in the
high price of the surveillance system. Hikvision,
as the largest manufacturer for this system,
is a typical giant national-owned enterprise.
Their crazy growth rate is visible in this
sheet, and the annual revenues in 2016 had
reached up to 4.6 billion dollars. In the
same period, the Chinese surveillance market
had grown 14 times, and still increasing at
the same speed.
Today, this national system continues to strengthen
itself with various high tech, such as face
recognition, AI analysis. In 2010, image identification
got a breakthrough with the deep-learning
algorithm. After several years' upgrades,
the camera can recognize the face in milliseconds,
whatever low light, side profile, or dim situation.
After the image capture, the system chooses
the one with highest quality.
And then it positions over 100 key-points
on the mouth, nose, eyes, and contour. After
a few analysis, the system can find the exact
ID among the database. In the meantime, it
also can real-time display the flow density,
gender, vehicle info, and other characteristics.
Relative to other countries, China has the
maximal human data for AI learning.
The more important thing is,
with the strong will of the central Government, what China could do is far-far more.
Maybe with the unlimited deep learning, the Chinese Skynet were to awakening firstly someday.
Enormous and uncontrollable.
Thanks for your watch. As the first video of my channel.
I'd go through many difficulties. At last, fortunately, I finished it.
