Video Intercom Installation in Melbourne: A Smart Choice for Security and Convenience If you're looking for a way to improve the security and convenience of your Melbourne property, then a video intercom system is a smart choice. This type of system allows residents or employees to see and speak with visitors before allowing them entry into the building, which provides added peace of mind and security.Installing a video intercom system typically involves running wires from the main intercom unit, located near the building's entrance, to each individual apartment or office. This can be done during the construction phase of a building or retrofitted into an existing structure.
