Video intercom greatly improves the safety and reliability of the access control system, and is suitable for scenarios with high requirements for identity verification, such as the VIP channel of high-end communities, the entrance of financial institutions, the gate of government units and the access control of data centers.
Core Application Scenarios of SIP Access Control Intercom
With the advantages of open protocol, flexible deployment and strong compatibility, SIP access control intercom has broken through the application limitations of traditional access control intercom systems, and is widely used in various civil and industrial scenarios. It can be connected with various access control and security equipment to form an integrated intelligent management system, and can also be integrated with the existing communication system of enterprises to realize the sharing of network resources and equipment resources.
Intelligent Access Control for Office Buildings, Parks and Communities
The most basic and mainstream application scenario of SIP access control intercom is the access control management of office buildings, industrial parks and residential communities. In this scenario, the SIP access control intercom terminal is installed at the main entrance, unit entrance and other key access control points, and is connected with supporting security equipment such as turnstiles and electromagnetic door locks to form a complete access control management system.

When an external visitor needs to enter, he can initiate a call to the property management center or the corresponding office through the intercom terminal, and the management personnel or the staff of the receiving department can conduct two-way voice or video intercom with the visitor in the background to verify the identity of the visitor. After the identity verification is passed, the management personnel can realize remote unlocking through the IP phone of the control center, and the turnstile or electromagnetic door lock will be opened synchronously to allow the visitor to enter.
The biggest advantage of SIP access control intercom in this scenario is the point-to-point communication capability with the IP phone of the control center. It can also be registered to the existing IPPBX telephone exchange of the enterprise or property, realizing the seamless integration with the existing communication system of the user. This integration mode makes the network application networking more simple and efficient, and the user can make full use of the existing network architecture and communication equipment without building an independent communication network for the access control system, which greatly reduces the construction and operation and maintenance costs.
Unattended Service Scenarios Represented by Parking Lots
With the development of intelligent management, more and more public service scenarios have adopted the unattended operation mode, and parking lots are the typical representative of such scenarios. In the unattended parking lot, the traditional manual access control and charging mode is replaced by the intelligent equipment such as automatic charging piles and license plate recognition systems, but in the actual operation process, visitors and vehicle owners often encounter various problems that need manual help, such as equipment failure, payment errors and entry and exit difficulties.

SIP access control intercom can perfectly solve the pain points of unattended scenarios. The intercom terminal is deployed at the entrance, exit and key positions of the parking lot. When the vehicle owner or visitor encounters a problem, he can initiate a help call through the one-touch or dial intercom terminal. Relying on the linkage capability of the SIP protocol, the system can synchronously establish a connection between the video image and voice signal of the help point and the IP phone of the background control center. The staff of the control center can view the real-time video situation of the on-site through the phone interface, conduct two-way communication with the person asking for help to understand the specific problem, and realize remote control of the on-site equipment such as turnstiles and barrier gates through the system to solve the problem of the person asking for help in a timely manner.
This application mode not only ensures the efficient operation of the unattended scenario, but also provides a timely and effective help channel for users, greatly improving the user experience and the management efficiency of the scenario.
Emergency Help and Alarm in Public Scenarios
In addition to the access control management scenario, SIP access control intercom terminal can also be widely applied in various public scenarios as an emergency help and alarm equipment, such as urban parks, residential communities, public transportation stations, various cultural and sports venues, schools and other places with large personnel flow and high demand for emergency help.
In these scenarios, the SIP access control intercom terminal is deployed at the emergency help points with dense personnel flow and blind areas of security management. Relying on the existing IP network of the scene, the system can build an independent emergency help and alarm network through the SIP protocol without building an additional dedicated communication network. The management side only needs to deploy SIP telephones in the command center to receive and process the help calls from each help point in a unified way. At the same time, the SIP access control intercom system can also be directly connected to the existing dispatch center and call center system of the government or enterprises.

As the mainstream communication protocol of the current call center industry, the SIP protocol has good compatibility with most dispatch and call center systems. Only by deploying the SIP help terminal on the site can the emergency help and alarm capability of the existing system be quickly expanded without building a separate emergency communication system, which greatly saves the construction cost and shortens the project implementation cycle. When an emergency occurs, the public can initiate an emergency call through the on-site intercom terminal, and the command center can receive the alarm signal and real-time video and voice information in a timely manner, and carry out rapid dispatch and rescue, which effectively improves the emergency response capability of the public scenario.
Core Advantages of SIP Access Control Intercom Compared with Traditional Systems
Traditional access control intercom systems mostly adopt the communication mode of proprietary protocols, which have obvious limitations in compatibility, scalability and system integration.

In terms of system expansion, the SIP access control intercom system has obvious flexibility. When the user needs to add access control points or intercom terminals, he only needs to deploy the new terminal on the existing IP network and complete the system registration and configuration in the background, without large-scale transformation of the original system. This flexible expansion mode can well adapt to the changing business needs of users and reduce the later expansion cost of the system.
Strong System Integration and Secondary Development Capabilities
SIP access control intercom system has strong system integration and secondary development capabilities, which can realize the linkage integration with various security and management systems. The system can be fused with the video gateway to realize the seamless linkage and integration application with various monitoring video streams. The real-time video image of the monitoring system can be synchronously pushed to the control center of the SIP access control intercom system, and the management personnel can view the monitoring video and conduct intercom communication at the same time, realizing the integrated management of video monitoring and access control intercom.
In addition, the SIP access control intercom system provides open API development interfaces, which can realize the deep integration with the user's existing business system, such as property management system, enterprise OA system, security dispatch system and so on. Through the secondary development of the API interface, the system can realize more abundant business-level application capabilities, such as the association of access control records with employee attendance, the linkage of alarm signals with the security patrol system, and the real-time push of access control information to the mobile terminal of the management personnel. This deep integration capability makes the SIP access control intercom system not only a simple access control and intercom equipment, but also an important part of the user's intelligent management system.
