What We Know About Smart Video Intercoms: Analysis and Privacy Risks

Smart video intercoms offer security and remote control, but at what privacy cost? Discover the risks and legal insights months after their market rise.

The widespread adoption of smart video intercoms has transformed home access management, integrating video surveillance and remote connectivity. Months after these technologies established themselves on the market, increasingly relevant critical issues regarding privacy and cybersecurity are emerging. The debate on how to reconcile the need for physical home protection with the safeguarding of personal data has become central for both users and manufacturers.

The Double Face of Connectivity: Between Remote Control and Data Exposure

Next-generation video intercoms offer advanced features for physical security, such as video surveillance, package detection, and remote unlocking via smartphone. As highlighted by Editoriale TuttoTech, "The operation of Wi-Fi video intercoms is very simple; ultimately, smart video intercoms are simply next-generation devices capable of connecting to the network to communicate in real-time with a smartphone." This constant connectivity represents a significant advantage in terms of convenience, but simultaneously exposes the home perimeter to potential cybersecurity risks.

The ability to communicate in real-time and open the gate remotely relies entirely on the WiFi network connection. Next-generation devices include features like suspicious motion detection and configurable notifications to avoid false alarms. Integration with established smart ecosystems like Amazon Alexa, Google Assistant, and Apple HomeKit amplifies voice control and automation possibilities, but also increases the amount of data shared with manufacturers' servers and the attack surface of the home network.

Biometrics and Automation: The Case of Facial Recognition

A particularly sensitive aspect under the lens of privacy is the integration of familiar face recognition. As explained by Editoriale TuttoTech, "A smart video intercom with familiar face recognition could open the gate by itself and turn on all the lights in the house." Home automation based on biometrics raises complex questions about how facial data is processed, stored, and protected from unauthorized access. The convenience of keyless or keypad-free access clashes with the need to ensure anonymity and the protection of sensitive data.

To balance these needs, some manufacturers have introduced specific features for privacy protection. For example, the EZVIZ CP5 model includes a voice changer feature designed to ensure user anonymity during remote conversations, allowing users to mask their original voice when answering the door without being physically present or without wanting to reveal their identity.

Analysis of Top Models: Hardware Specifications and Implications

On the market, several models illustrate the contrast between advanced features and potential vulnerabilities. The EZVIZ CP5 model stands out for its 7-inch color touchscreen and a 134-degree viewing angle, which ensures broad visual coverage but raises questions about framing public outdoor areas. The device offers 1080p resolution, infrared night vision range up to 5 meters, and 2.4/5 GHz Dual Band Wi-Fi support for a more stable connection. On the access control front, it includes two RFID cards for managing openings, but its weight of 1.47 kg requires careful structural installation.

The Arlo Wired Video Intercom offers specific security features such as pre-recording to eliminate delays in capturing events and courier package detection. Pre-recording involves continuous image buffering, a practice that requires careful management of local or cloud storage. This model also offers 1080p resolution. The Nest Doorbell, on the other hand, runs on battery to facilitate installation and is optimized for remote conversations via Google Assistant, accentuating dependence on the manufacturer's ecosystem.

It must be noted that the analyzed sources present conflicting information on some devices. For example, the Ring Video Doorbell Pro 2 is described in some cases as a battery-powered, budget-friendly device, while in others it is indicated as mid-range. This discrepancy generates confusion about the product's actual technical specifications and makes it more complex for the user to accurately assess the balance between costs, benefits, and security risks.

Active Privacy: Hardware Solutions for User Control

Faced with the risks associated with perpetual connectivity, some manufacturers have integrated hardware solutions to return control to the user. The Bticino 344652 model represents a significant example in this regard, introducing an indicator LED for call exclusion. This feature allows users to know if the call has been disabled, ensuring maximum privacy and peace of mind regarding the possibility that the device is actively listening or recording without the user's consent.

The same Bticino model favors direct physical interaction, featuring a side joystick for manual adjustment of the display's color, brightness, and contrast, as well as the audio volume and ringtone volume. These options make the device extremely customizable according to user needs. With dimensions of 16.45 x 2.05 x 16.5 cm and a weight of 510 grams, the video intercom is compact and lightweight, without sacrificing robustness and build quality.

The Regulatory Framework: When an Intercom Becomes a Video Surveillance System

Home security should represent a balance between technological solutions and more traditional physical measures. Smart video intercoms have numerous limitations that must not be overlooked: considering all the pros and cons helps in making informed decisions and ensuring complete protection without relying exclusively on technology.

From a legal standpoint, the installation of video intercoms imposes stringent privacy obligations. It is necessary to display specific signs stating that the area is under video surveillance. These signs must also indicate who is carrying out the recording and its purpose. However, regulations establish that a video intercom cannot be considered a video surveillance system in the strict sense: its main objective is to recognize who is ringing the bell, not to watch over a specific area for security purposes. Furthermore, in video intercoms, images are not recorded in the vast majority of cases.

The fine line between an intercom and video surveillance blurs when the system is expanded. The ability to equip the video intercom system with additional cameras allows for home video control of different areas of one's house or condominium. This effectively sets up a small video surveillance system. Even in this case, it is possible to operate without additional image recording and data storage devices, framing public outdoor areas and respecting privacy issues only if any form of video archiving is avoided.

Frequently Asked Questions

Are smart video intercoms considered video surveillance systems by law?: Not in the strict sense. The video intercom serves to recognize who is ringing, and in most cases, does not involve image recording. However, adding cameras for home video control can configure the system as a full-fledged video surveillance system.
What are the privacy obligations for installing a video intercom?: The law requires the posting of signs indicating video surveillance of the area, clearly specifying the entity carrying out the recording and the purpose of the data collection.
How can smart devices protect users' privacy?: Some models integrate targeted features such as the call exclusion indicator LED, which informs the user about the device's status, or the voice changer for anonymity, useful for masking identity during remote conversations.
