Visible cat's eye: How to deal with security and hidden in [Smart cat's eye] in security?

Because the traditional peephole relies heavily on light and its easy disassembly is easy to be used by criminals, in recent years, electronic smart peephole, smart visual peephole video doorbell, and smart door locks with monitoring functions have entered more and more homes. As a "family guard" has even become a standard configuration in some high-end communities.

This type of product usually has functions such as motion detection, infrared night vision, voice intercom, high-definition infrared night vision, but what is unexpected is that the high-definition infrared night vision, as the core function of security, is the driving force of the smart cat’s eye, which is in the smart cat’s eye. Push to the cusp of the storm.

For the concealment of residential owners!

Judging from the feedback from netizens, in some old communities, due to structural problems, the doors between neighbors are often facing each other. If neighbors install such equipment, the "infrared light source" can be clearly seen at night. This kind of situation that makes people feel that their lives are being monitored will cause great psychological discomfort.

In other words, the smart cat eye may completely record the daily access information of neighbors and can track and analyze it, which may be suspected of snooping. Due to the complexity of the subject and the lack of corresponding supervision, private collection of public images has greater hidden dangers.

What's more worrying is that in order to allow Smart Maoyan to record 24 hours a day and get rid of the performance limitations of memory cards, "cloud storage" is now popular. So, is the background storage of recorded videos safe? Even if the neighbor is not malicious, if the information recorded in the cloud is leaked, it is equally dangerous.


Thoughts on improving privacy

Due to the lack of specific details in the information provided by netizens, it is difficult to determine which product is being used and under what circumstances the "infrared light source" is seen. Therefore, suggestions for improvement will be made from two perspectives.

From a biological point of view, infrared light is usually invisible to the naked eye. The so-called "infrared light source" by most netizens is essentially the light of the indicator light, which is used to prove the working status of the relevant module. Based on this, relevant manufacturers can consider canceling the indicator light in subsequent product optimization, which can alleviate the psychological discomfort of the masses.

From a hardware point of view, there may be two situations that make people feel like seeing an "infrared light source".

The first is the existence of the "red storm" phenomenon. In theory, the infrared light emitting tube emits a lot of infrared light when it is working, and people can see red light at the same time, giving people the impression that it emits visible red light, exposing infrared light. The concealment of the luminous tube, this phenomenon is called the red storm.

The second is the wavelength issue. In theory, the human eye can perceive common near-infrared light, but each person’s perception ability will vary. That is to say, when the intensity of infrared light is large enough, if it is directly irradiated on the human retina, it will also give people a certain feeling.

However, the longer the wavelength, the weaker the perception ability of the human eye, the smaller the explosive power of red light, and the worse the light supplement effect.

But it is worth noting that, as a problem that has plagued the security industry for many years, every leap in low-light camera technology means that infrared light sources with relatively longer wavelengths can be used.

At present, the low-light camera technology has passed the dark light level (0.1Lux), moonlight level (0.01Lux) and starlight level (0.001Lux). At present, mainstream cameras have reached starlight level, the lowest illuminance color has reached 0.0005Lux@ (F1.2, AGCON), and the black and white has reached 0.0001Lux. This also shows that the current "psychological" discomfort brought to people by smart cat eyes is expected to be resolved.


There are different opinions on the criteria for judgment, and sound laws and regulations need to be established

As the video doorbell has more and more functions, especially cloud storage, AI face recognition and other functions, it is more likely to cause the personal privacy of "neighbors" to be collected or even leaked. According to industry insiders, the current supervision in this area is almost blank, it is difficult to obtain evidence, relevant laws and regulations lag behind the development of the industry, judgment standards are not clear, and problems such as difficulty in sentencing and conviction have emerged.

According to judicial officials, Article 1032 of the Civil Code Law implemented on January 1, 2021 stipulates: "Privacy refers to the privacy of the private life and private space of natural persons, private activities, and privacy that they do not want to be known by others. Information" clearly incorporates "private life peace" into the scope of privacy protection. Prior to this, my country's laws did not directly stipulate the concept of "privacy".

However, the new "Civil Code Law" does not specify the scope of "private space." Among the many opinions of the judicial department, it can only be determined through general cognitive inferences that "installing cameras in the corridors of residential buildings to monitor residents' activities in and out of public passages and elevators will create a certain degree of psychological freedom for residents. Moderate, A living environment without oppression and restraint is also an important part of the tranquility of private life." Then determine the act of infringement and demolition.
