Access control in buildings with multi-tenants has grown more complicated. Analog intercom systems traditionally use dedicated wiring that requires a lot of time to install and is costly to maintain. As apartment complexes grow larger and residents require more convenience and security with remote accessibility, these legacy systems are not able to scale to meet demand. Developers and property managers today need a smarter, more scalable solution. SIP intercom systems provide exactly that: leveraging IP networks for clear audio-visual communication and centralized management.

Uniwin-Global specializes in Android & Linux-based SIP intercom motherboards and complete hardware-software solutions for smart apartments and villa projects. Our systems combine advanced technology with easy installation and future-proof scalability. Below are five key benefits of choosing a SIP intercom system for your multi-tenant building.
Lower Wiring Costs with Existing Network
Simplified Infrastructure
While other analog systems require separate cabling, SIP intercoms utilize the standard Ethernet or Wi-Fi connection. No additional phone lines are required, and neither are complex wiring routes-just plug into the existing IP network. The result of using SIP intercoms is a dramatic reduction in installation time, labor, and materials.
Flexible Deployment
Uniwin-Global’s WO501 5-inch outdoor station offers plug-and-play setup, with SIP-based audio and video intercom functions. It also supports one-to-one and group calls while integrating face recognition, identity verification, and blacklist alerts. The dual-lens wide dynamic camera can adjust to ambient light in various environments and supports face databases from 5,000 to 20,000 entries, satisfying both new constructions and renovation projects.
Real Value for Developers
Reusing the existing infrastructure can cut wiring costs as much as 40% for developers using SIP intercom systems, thus optimizing the budget and reducing installation time across multiple properties.

Expansion is Easy for Large Communities
Designed for Growth
The analog intercom systems more often than not suffer from capacity limits when the residential communities grow. SIP intercoms are built around IP architecture, which can easily scale to hundreds and even thousands of units. Because of this trait, these are highly suitable for high-rise buildings, gated communities, and even mixed-use developments.
Centralized Management
All units are monitorable and controllable from a centralized interface with Uniwin-Global’s SIP solution. Property managers can add users, schedule maintenance, and update firmware remotely-all of this without setting foot on site. The system also supports visitor registration, uploading door-opening records, and attendance data export via web portal or WeChat mini-program.
Example Integration
SIP intercoms can integrate with the facial recognition access control and attendance management systems on either a local or wide-area network for easy expansion as the growth of the community occurs.
Mobile App Remote Access
Integrated with Smartphones
Today, users expect smart solutions that seamlessly integrate with their mobile devices. Our SIP intercom systems provide mobile app support so that residents can see who is at their door and unlock it remotely from anywhere in the world. It can be matched with an indoor unit or WeChat mini-program for two-way audio and video intercom and remote door opening functions. This flexibility is ideal for busy professionals or families who value both convenience and security.
Real-Time Notifications and Access Logs
Our systems provide real-time push notifications when the doorbell rings or in case of any unauthorized attempts to access the building. The system keeps detailed logs of all entries and exits. This helps property managers monitor activities within the building effectively, while offering peace of mind to residents regarding who accesses their premises.
Enhanced security with HD video calls.
Clear Visual Identification
In any residential environment, security is the most vital issue. SIP intercoms with HD wide dynamic cameras ensure that homeowners can easily identify visitors before allowing them into their homes. Uniwin-Global’s WO801 8-inch outdoor station is featured with face recognition, card access, and button-based exit control. The wide dynamic imaging and HD video output minimize the risk of impersonation or unauthorized entry.
Two-Way Audio & Multi-Zone Monitoring
With its split-screen viewing and two-way video calls, the WI704 7-inch indoor monitor supports entry point monitoring in multi-monitoring mode. Residents can also unlock doors remotely and combine the convenience with real situational awareness.
Safer Communities, Reduced Risk
With highly accurate face recognition, live video verification, and encrypted SIP communication, Uniwin-Global systems help property managers build a safer, more trustworthy living environment.
Seamless Integration with IP Security Systems
Open Protocols for Easy Connectivity
The strongest point of a SIP intercom system is interoperability. The devices from Uniwin-Global support MQTT, HTTP, and WebSocket protocols, and are therefore compatible with most IP cameras, alarms, and smart lock systems on the market. That flexibility means seamless integration when either upgrading existing systems or doing an entirely new installation.
Future-Proof Investment
Our intercom products run on the advanced Android and Linux platforms, which are perfectly suited to custom application development and long-term scalability. For example, the Rockchip RK3588 Reference Model M588 delivers:
- 6-core architecture (Cortex-A76 x4 + Cortex-A55 x4)with AI & Multimedia applications.
- 6T computing power and a main frequency of up to 2.4GHz.
- integrated LVDS/MIPI/eDP/HDMI/Ethernet/WiFi & BT
- Android 12 system with open APIs for developers.
- Cross-platform compatibility (Linux/KylinOS/Tongxin UOS/HarmonyOS supported).
This means your SIP intercom investment keeps on delivering value through regular software upgrades and evolving smart-building integrations.

Conclusion
SIP intercom systems represent the future of secure, efficient access control for modern multi-tenanted apartments and large developments. They reduce wiring costs, scale up easily, integrate with mobile devices, increase building security, and connect seamlessly with existing IP infrastructure. By choosing a Uniwin-Global SIP intercom solution, such as the WO501, WO801, and WI704, you can offer residents a safe, convenient, and technologically advanced way of living.
