Main Text

1.1.1 Design Purpose

The design includes the following systems: video intercom system and access control system based on video intercom, smart home system, community services, etc.

From the user’s perspective, smart homes are composed of three networks: home network (HOMENET), community management network (INTRANET), and international interconnection network (INTERNET). The full application of these three networks allows the network to enter homes, come closer to life, and reflect the true meaning of smart homes. The smart home system in households is driven by this strong demand, belonging to the home network category. It is this system that makes people feel that the network is nearby, omnipresent, allowing them to fully utilize network resources and advantages in work, study, and life, leading to an efficient, convenient, and safe life.

The video intercom system is a fully digital residential smart system based on the community Ethernet platform (TCP/IP transmission protocol). This system utilizes the Ethernet transmission platform within the community to digitally transmit all video, audio, monitoring, control, and status information. It integrates various functions such as video intercom, information release, security alarms, access control, and various rich residential environment controls, all coordinated and unified, organically merged into one.

1.1.2 Design Scope

We can provide system design, software and equipment supply installation, system installation debugging, system linkage debugging, user training, acceptance, and after-sales service for the video intercom access control system for a certain plot.

The system covers the entrances and exits of each residential building, each unit, as well as the underground parking lot and community entrances.

1.1.3 User Demand Analysis

The video intercom access control system for a certain plot needs to adopt a color touch screen, digital video intercom system, with indoor units installed in each unit, a wall-mounted unit at the community entrance, and an access control unit in the residential lobby, as well as access control for the underground parking lot.

1.1.4 Functions of the Video Intercom Access Control System

This design plan for the video intercom system is based on the MOX video intercom system and takes into account the functions of other brands.

System Functions:

1. Three-party call function

Function Overview:

Visitor and resident communication: When a guest visits, they dial the resident’s number through the unit entrance unit, and the corresponding indoor unit emits a harmonious ringing sound while transmitting the visitor’s image to the indoor unit’s visual module. Picking up the microphone allows for communication.

Visitor, resident, and management center communication: The visitor can call the resident and management center through the entrance unit to achieve two-way intercom.

The management center can notify the resident and also call the resident’s extension through the management machine for two-way intercom; the resident can directly call the management center through the indoor unit, and the management center will display the resident’s information.

2. Access control function

Function Overview

Remote unlocking: After the visitor calls the resident, if the host needs to meet the visitor, they just need to press the door opening button on the indoor unit, and the door will automatically open. After the visitor enters, the door will automatically close; the central administrator can also remotely open the electric lock of each building entrance through the management machine.

Password unlocking: Residents can also open the community gate with a password, with 256 sets of passwords, and residents can change their passwords at any time, ensuring safety and convenience.

Induction card unlocking: Residents can use an induction card to unlock the main entrance of the building, and this induction card can participate in the apartment’s one-card system. It can adopt independent access control, networked access control, or reserved access control slots for convenience.

3. Security alarm function

Function Overview

Alarm settings: Up to 8 alarm zones, expandable; residents can directly set alarms (arming, disarming, etc.) through buttons on the indoor unit, with menu display for simplicity; alarm zone types can be set (i.e., alarm, follow-up, delay, 24-hour monitoring), adapting to different types of alarm detectors; residents can set or modify passwords (including master, guest codes, anti-hijacking codes) to make settings more professional.

Alarm information release: When an alarm occurs at the resident’s home, the indoor unit immediately transmits the alarm signal to the management center, and the management machine emits an alarm sound while displaying the resident’s room number and alarm type for timely handling by property personnel.

4. Information release function

Function Overview

Information group call: The management center can edit specific text information (such as weather forecasts, community activities, fee notifications, etc.) through information release software and send it to all residents or a specific unit (area), and all residents can receive the same information.

Designated information sending: The management center can edit specific text information (such as urging the payment of property fees, etc.) through information release software and send it to designated residents based on room number and other information.

Information inquiry: All sent information can be queried and printed through information release software.

Smart mailbox information notification: When there are new letters in the mailbox, the indoor unit can receive information prompts sent from the mailbox.

5. Image monitoring function

Function Overview

Residents can monitor the unit entrance machine or individual door machine through the indoor unit to check the situation at the door.

The management machine can monitor the situation at the unit entrance machine.

6. Image storage function

Function Overview

When the owner is not at home, if there are visitors, the system will automatically record the images of the visitors.

When the owner returns home, they can browse the images of the visitors through the indoor unit, making it very convenient to know who visited during this period for follow-up contact.

7. Inter-unit communication function

Function Overview

Indoor units between residents can communicate with each other, and the master unit can actively call the subunit, just like an internal phone, without incurring any phone charges (visual calls: optional).

For duplex structures with visual intercom subunits, the subunit can communicate directly with visitors and open the door for them, while the terminal can call the subunit and communicate with it.

8. Door status alarm function

Function Overview

The exterior of the entrance unit has protective measures to prevent abnormal disassembly, and when abnormal disassembly occurs, the alarm information will be reported to the management machine.

If the electric anti-theft door is opened for more than 120 seconds, the management machine will have sound and light alarm prompts and display the door number.

9. Software management function

Function Overview

The system uses fully software-based management, and managing with a PC has the following benefits:

Large information storage capacity. Traditional management machines are single-chip mode with limited information storage, while using a PC stores information on the computer hard disk, greatly increasing information storage capacity.

Convenient for adding and integrating system functions, all functions are modularized in software, eliminating the need to categorize management machines into several types (visual/non-visual, etc.).

Convenient for integration with other weak current systems, many weak current general contractors need to integrate the entire weak current system into IBMS. Now, only mutual software communication is required, and IBMS can easily extract the operation status and device parameters of intercom devices from our software, while traditional management machines require collecting a large number of dry nodes or simply cannot collect them.

Convenient for system upgrades and maintenance. The PC operating system adopts the most popular WINDOWS, and technical personnel can provide remote technical support. In the 900 system, remote upgrades of indoor units and other devices can also be done through software, which traditional management machines cannot achieve.

10. Interface customization function

Function Overview

The interface of the indoor unit can be customized according to customer requirements.

11. Management machine C/S architecture

Function Overview

C/S architecture: multiple management machines jointly manage IRIS devices. Among these management machines, one must have database server functionality, and all management machines synchronize data updates (such as call data, alarm data, etc.) with the database server through Ethernet, allowing mutual call transfer and collaborative work.

1.1.5 Video Intercom Access Control System Architecture

The system adopts a digital intercom system based on TCP/IP network transmission.

1.1.6 Smart Home System (Expandable Functions Reserved)

Humane design promotes smart homes to open a beautiful new life, as people yearn for the art of perfect living. Now, just one button is needed, and an easy life begins.

Music, lighting, cinema, screen… all elements seem to be illuminated by you, presenting an unparalleled sense of harmony. Sitting on a comfortable sofa, watching your favorite movie, or listening to your favorite music. The wall lamp’s light is just right, and the night outside is clear.

Materialism does not equal an ultimate life. Intelligence brings people an unprecedented freedom. Just a little effort, all details flow around you smoothly.

Smart homes bring the best things in the world to those who understand and deserve them. For those who advocate the perfect art of living, enter the ultimate life journey customized wholeheartedly by the editor of the house search with perfect images, pure sounds, and freely changing light and shadow.

Before structuring our smart home plan, let’s take a look at the current living scenarios of most families and their desire for intelligence:

There are many home appliances at home, including TVs, DVD players, audio systems, air conditioning, electric curtains, remote-controlled fans, etc. Each appliance has its remote control, making it cumbersome to switch between several remote controls!

Home appliances can be remotely controlled, which is indeed very convenient. If all the lights in the house could be remotely controlled, how great would that be! If you could press a button before sleeping to turn off all the lights in the house, how convenient would that be!

The living room has many background lights (downlights, spotlights, chandeliers, wall lamps, etc.), which can either be fully on or fully off. Over time, they become decorations and waste electricity! If the switching on, off, brightness, and dimness of these lights could be combined, that would be so cool! This way, there would be dining lighting effects for meals, guest lighting effects for meetings, cinema lighting effects for watching TV or DVDs, and even different lighting effects corresponding to seasonal and emotional changes, which would be thoughtful!

Using traditional hard wiring to achieve two-way switches is too complicated; not only is the wiring complex, but it cannot be resolved without a certain level of electrical skills! Smart switches can freely achieve two-way or multi-way switching, and the lights in the garage, courtyard, corridor, or stairway can automatically turn off after a few minutes of being turned on.

When you are watching TV and the phone rings, you have to fumble to lower the TV volume when answering the phone. How great would it be if the TV volume could automatically lower when you pick up the phone and return to its original volume when you hang up!

Whole-house background music sharing is currently a hot topic in home decoration. Every room in the house (including the kitchen and bathroom) can independently listen to music, listen to radio broadcasts, freely switch audio sources, and adjust the volume without interference.

Burglars breaking in, gas leaks, and house fires are safety hazards at home. If there can be timely alerts and automatic calls to report emergencies when something goes wrong at home, that would be great! If family members encounter coercion or emergencies, pressing a button can automatically dial the phone number set by the homeowner and send emergency rescue information, allowing family members to receive real-time assistance.

If the whole family goes on vacation for an extended period, they can be promptly informed of any alarms at home. When no one is at home, an illusion that someone is home can be created to “confuse and keep thieves outside the door.” For example, during vacation, the electric curtains in the living room and master bedroom can automatically open at 7:00 AM and close at 8:00 PM; next, the daylight lamps and TV in the living room can automatically turn on at 8:00 PM and turn off at 10:00 PM; then, the ceiling light in the bathroom can automatically turn on at 10:30 PM and turn off again; finally, the wall lamp in the master bedroom can automatically turn on at 11:00 PM and turn off at 11:30 PM.

When you leave for work, just click to activate “work mode” on the LCD touch screen at the door, and all the lights in the house will turn off, curtains will automatically close, appliances will enter energy-saving mode, and gas and water valves will automatically close, while home monitoring devices and infrared anti-theft systems will automatically activate.

At the office, you can remotely operate the camera through the internet to check the situation at home. If there is an illegal intrusion, the system will automatically report to the community property management center or the phone number set by the resident.

On the way home, you can activate “home mode” via your smartphone to pre-open the air conditioning, curtains, water heater, etc., so that when you arrive home, you are welcomed by a suitable temperature, comfortable lighting, and a bathtub filled with hot water.

Specifically, digital homes will break the previous communication application model dominated by phones and computers, replacing it with a home gateway as the control and management center, connecting computers, phones, digital appliances, security systems, lighting systems, and other smart terminals within the home to the wide area network, thus achieving a digital home network experience centered on multimedia communication, entertainment, security, and smart home control. Digital homes will bring people a more efficient and convenient modern lifestyle.

Today, all of this is integrated into smart homes, allowing people to integrate smart systems according to actual home needs and experience the charm and convenience of technological living.
