Specifications for Video and Image Information
Collection in Public Security Key Areas
1 Scope
This Standard specifies the video and image information collection location and
collection type, technical requirements and collecting device requirements for the
public key areas.
This Standard is applicable to the video and image information collection and
management for the public key areas, key industries and fields involved the public
areas in the public security video surveillance network system.

5 Technical Requirements
5.1 Collection principle
According to the site conditions and application requirements, information collection
shall follow the following principles:
a) The information collection shall follow the principles of data authenticity and
integrity;
b) The principle of maximizing the extraction of the collected target information;
c) The principle of optimizing the feature extraction of target information;
d) The principle of fastest responding to the input information on site.
5.2 Basic requirements for collection
5.2.1 The collected video and image information shall meet the requirements for target
recognition and shall cover the range of monitoring. The wide range of macroscopic
observations shall be combined with fixed monitoring of the specific target areas; while
the time-sharing scanning shall be combined with real-time tracking specific target.
When using multiple cameras to monitor in different areas, the monitoring areas shall
be connected with each other; so that achieve effective coverage of the entire
monitoring area.
a) The supporting image formats include JPEG, JPEG2000, BMP, PNG, TIF, etc.;
the image size pixel is no less than 1920×1080;
b) Horizontal resolution: when the ambient light is no less than 300lx, the resolution
shall be no less than 900TVL; when the ambient light is 0.1lx below, the
resolution shall be no less than 650TVL;
c) The maximum brightness discrimination level shall be no less than Level-10;
d) Color reproduction: when the ambient light is no less than 300lx, the average ΔE
≤15.
5.5 Overlay information requirements
If the character information is overlaid on the video and image information, it shall not
shield the important targets and focus areas on the video and image.
5.6 Requirements for the number of target pixel of the video and image
information for target recognition
When the target is imaged on the imaging surface of the camera, and can best reflect
the shooting location and conditions of the target features:
a) When it is required to distinguish the physical characteristics of the person (such
as gender, clothing, body type, etc.), the number of the vertical pixels of the target
shall be no less than 200;
b) When it is required to distinguish the carrying items of the person (such as
carrying method, item type, etc.), the number of the vertical pixels of the target
shall be no less than 300;
c) When it is required to distinguish the facial features of the person (such as hair
style, facial features, accessories), the number of the horizontal pixels of the
person’s head shall be no less than 300;
d) When it is required to distinguish the vehicle type, the number of horizontal pixels
of the target shall be no less than 180;
e) When it is required to distinguish the vehicle license plate number, the number
of the horizontal pixels of the license plate shall be no less than 100.
5.7 Quality requirements for audio information
For the collected audio information only used for voice intercom, its digital audio
sampling frequency shall be no less than 8kHz; the number of sampling digits shall be
no less than 8. For those used for the environmental sound collection, its digital audio
sampling frequency shall be no less than 16kHz; the number of the sampling digits
6.2.2 Storage interface
Interface such as USB interface or SD/Micro SD memory card shall be connected to
an external storage medium.
