Initiatives on the Use of Video Products
Thank you for choosing EZVIZ products.
Technology affects every aspect of our life. As a high-tech company, we are increasingly aware of
the role technology plays in improving business efciency and quality of life, but at the same time,
the potential harm of its improper usage. For example, video products are capable of recording
real, complete and clear images. This provides a high value in retrospect and preserving real-time
facts. However, it may also result in the infringement of a third party’s legitimate rights and interests
if improper distribution, use and/or processing of video data takes place. With the philosophy
of “Technology for the Good”, EZVIZ requests that every end user of video technology and video
products shall comply with all the applicable laws and regulations, as well as ethical customs, aiming
to jointly create a better community.
Please read the following initiatives carefully:
1. Everyone has a reasonable expectation of privacy, and the installation of video products should
not be in conflict with this reasonable expectation. Therefore, a warning notice shall be given in a
reasonable and effective manner and clarify the monitoring range, when installing video products
in public areas. For non-public areas, a third party’s rights and interests shall be evaluated when
installing video products, including but not limited to, installing video products only after obtaining
the consent of the stakeholders, and not installing highly-invisible video products.
2. The purpose of video products is to record real activities within a specic time and space and
under specific conditions. Therefore, every user shall first reasonably define his/her own rights in
such specic scope, in order to avoid infringing on a third party’s portraits, privacy or other legitimate
rights.
3. During the use of video products, video image data derived from real scenes will continue to be
generated, including a large amount of biological data (such as facial images), and the data could
be further applied or reprocessed. Video products themselves could not distinguish good from bad
regarding how to use the data based solely on the images captured by the video products. The result
of data usage depends on the method and purpose of use of the data controllers. Therefore, data
controllers shall not only comply with all the applicable laws and regulations and other normative
requirements, but also respect international norms, social morality, good morals, common practices
and other non-mandatory requirements, and respect individual privacy, portrait and other rights and
interests.
4. The rights, values and other demands of various stakeholders should always be considered
when processing video data that is continuously generated by video products. In this regard, product
security and data security are extremely crucial. Therefore, every end user and data controller,
shall undertake all reasonable and necessary measures to ensure data security and avoid data
leakage, improper disclosure and improper use, including but not limited to, setting up access
control, selecting a suitable network environment (the Internet or Intranet) where video products are
connected, establishing and constantly optimizing network security.
5. Video products have made great contributions to the improvement of social security around the
world, and we believe that these products will also play an active role in more aspects of social life.
Any abuse of video products in violation of human rights or leading to criminal activities are contrary
to the original intent of technological innovation and product development. Therefore, each user shall
establish an evaluation and tracking mechanism of their product application to ensure that every
product is used in a proper and reasonable manner and with good faith.
