Integrating a video intercom system with your CCTV setup enhances security by allowing you to see and communicate with visitors before granting access. This integration can be achieved using different types of intercom systems:
1. 2-Wire Intercom
A 2-wire intercom system uses just two wires for both power and data transmission. It's easy to install and is often used in retrofitting existing buildings. However, it may offer fewer features and lower video quality compared to more advanced systems.
2. 4-Wire Intercom
A 4-wire intercom system separates power and data transmission into four wires, offering improved performance and reliability. This system is more robust and can support higher video quality and additional features like remote access.
3. IP Intercom
An IP intercom system operates over a computer network, similar to IP cameras. It provides the highest flexibility, video quality, and integration capabilities. IP intercoms can easily integrate with NVRs and other network devices, offering seamless communication and video monitoring.
