The body is made in the form of three separate parts, connected to each other by means of screw fasteners. The rear surface of the case is equipped with a cooling system consisting of heat pipes that remove heat from the camera, mini-computer, internal and external radiators.

The technical result of the invention: increasing the level of security and expanding functionality due to the introduction of a system for detecting and recognizing users' faces into the intercom.

The specified technical result in the implementation is achieved by the fact that the intercom consists of a body in which there are an analog board that controls the main functions of the device, a keyboard unit, an IP camera, a speaker, a microphone and a key reader board.

The peculiarity lies in the fact that the front panel of the case is made without protruding parts or elements and is equipped with holes for placing an IR illumination, a speaker, an IP camera, a keyboard, a microphone and a key reader, and the case itself, in addition to the main control board, is equipped with an additional mini-computer, managing local video analytics - face recognition to open the door, as well as performing remote configuration. The side surface of the case is equipped with a hole for a contact block, and the bottom part is equipped with a hole for an Ethernet connector. The body is made in the form of three separate parts, connected to each other by means of screw fasteners. The rear surface of the case is equipped with a cooling system consisting of heat pipes that remove heat from the camera, mini-computer, internal and external radiators.

The design of the invention is shown in the figures.

Figure 5 - the composition of parts and intercom devices.

Figure 6 is a block diagram of the main units of the intercom.

The device consists of case 1, main board 2, membrane 3, button 4, cover 5, camera 6, bracket 7, front panel 8, microcomputer (Orange_Pi) 9, camera window 10, internal radiator 11, external radiator 12, screws 13 and 14, heat pipe 15 of camera 6, antenna window 16, heat pipe 17 Orange_Pi, screws 18, 19 and 20, washers 21 and 22, nuts 23, speaker 24, speaker holder 25 24, screw 26, NFC reader 27, bolt 28, nuts 29, radiator pressure plate 30 12.

The block diagram of the main intercom units (Fig. 6) shows a camera 6, a microcomputer (Orange_Pi) 9, a speaker 24, a microphone (31), a MIFARE NFC card reader 27, an analog board 2.

The device operates as follows.

The intercom keypad consists of 13 metal keys - from 0 to 9 (keys for dialing the subscriber's number), C (call reset), B (subscriber call), 13 key is programmable. Depending on the needs of the intercom user, this can be either a concierge call or communication with emergency services 112. The keypad is equipped with a two-color indication of the subscriber's number, when dialing the number, the selected keys are alternately highlighted in a different color (by default, all keys are highlighted in a single color). Additionally, for convenience, there is a sound indication of dialing, this function, like all sound signals of the device, is programmable with the ability to install third-party sound indicators in the service mode of intercom control.

When dialing the apartment number on the intercom keyboard, the call is made both to the subscriber handset installed in the apartment and to a mobile device authorized in the system to receive calls. The door can be opened from both of these devices. Calls are made using wired communication channels or a SIP server. SIP calls are controlled using a mini-computer installed in the case and connected to the Internet. The conversation is carried out by the visitor using the speaker and microphone installed in the intercom case.

The IP camera installed in the intercom is designed for several tasks:

Recognition of the visitor's face and opening the door if it matches the base of authorized users;

Live broadcast of the camera's video stream to the mobile application;

Recording a video stream to a video archive.

There are two ways to open the door without making calls - using the MIFARE system key or using the face recognition system if the subscriber is authorized in a specialized database. MIFARE technology was chosen as the most satisfying modern security requirements, keys are more protected from inconsistent copying in comparison with other technologies.

Keys are recorded both remotely using the software provided by the manufacturer, and locally in the key recording mode (available only in the service mode). Information about the database of registered keys is stored in the protected components of the analog board and is available in the service mode of intercom control.

The key reader is an antenna in the MIFARE NFC format installed on the bottom of the device under a protective glass.

The face recognition system works locally, independently of external servers, thus, it will work even if there is no Internet connection. This solution can significantly reduce the cost of face recognition services for end users of the device.

In addition, in the absence of an Internet connection, the intercom will perform all the analog functions of the device - opening the door with a key and from the inside using a button, making calls to subscriber handsets.

The developed analog board allows you to interact with the most common switches (Metakom, Vizit, Tsifral), 12 W power supplies and well-known types of handsets. This solution allows you to minimize the cost of replacing equipment in secondary housing stock.

The service mode of intercom control is carried out using a mini-computer equipped with a WI-FI module. Configuration can be carried out both remotely using any device with a browser, and locally (even if there is no Internet connection) via WI-FI connection. The user with the rights of the device operator has access to the settings of the base of apartments and keys, the base of the service settings of the intercom, and so on. Settings can be made both for an individual doorphone and for the entire network of connected devices.

Thus, the selected design and its constituent elements, in conjunction with the implemented device control logic, are designed to provide maximum comfort in using the intercom for both end users and service companies involved in its installation and maintenance. One of the key characteristics of the device is the above-mentioned face recognition system, which does not require additional costs for server power to launch and operate it.
