Same old cables, new intercom

Retrofitting old residential complexes with a modern two-wire HD video intercom system is more than an upgrade. For many homeowners and renters, these systems represent a leap into the future of residential living, bringing helpful intercom functionality – even on the go.

When new apartment blocks are constructed, many feature digital video intercom systems. These fulfil residents’ growing demands for enhanced security and greater convenience from their entry systems. It’s no wonder that those who live in older properties are becoming increasingly dissatisfied with the poor user experience of their current outdated intercom setups.

The need for change

There are a number of important problems associated with outdated intercom systems. On their own, each of these would not, perhaps, be sufficient justification to upgrade the system; taken together, however, the case for change becomes compelling.

Old intercom systems lack many modern features which have, over the years, become regarded as almost essential for modern apartment living. For example, we expect such systems to include high-definition video, so we can see who is calling. Ideally, we also want to see who is calling even if we are not at home. As a result, mobile connectivity and integration with smart home devices have become part of the minimum requirements for modern intercom functionality.

Another issue, and one that becomes increasingly important as time goes by, is the maintenance costs associated with keeping old systems running. As finding replacement parts for obsolete technology becomes more challenging, maintenance costs rise for property managers and, ultimately, residents.

Old systems are also notoriously poor when it comes to scalability. Expanding the functionality or coverage area of an old analogue intercom system can sometimes require a complete redesign and rewiring of the system.

functionality, existing two-wire cabling

Many old intercom systems were based on a two-wire copper cable system. These existing wires form the heart of the intercom infrastructure for the entire block. The great thing about modern two-wire systems is that, although they can offer the full range of modern functionality, they still operate over the existing copper wire infrastructure within the building. As a result, retrofitting a new intercom system is therefore relatively simple and cost-effective, and can be carried out with minimal disruption to residents.


Hikvision’s two-wire HD intercom solution

Hikvision offers two-wire HD video intercom solutions, which blend advanced technologies with a range of modern user-friendly features.

High-definition video and audio: Hikvision’s two-wire chip technology enhances wire compatibility to deliver smooth audio, video, and control signal transmission across existing cables with a very high bandwidth. Its optional 2 MP door station features wide dynamic range (WDR), works in low-illumination situations, and provides residents with a wide, ultra-HD video viewing angle for enhanced security and comfort.

Enhanced user experience: Residents may live in an older apartment block, but if it has been retrofitted with a Hikvision two-wire intercom system, they will enjoy a great, modern, user experience. For example, the 7-inch touchscreen indoor station features touch buttons, clear indicators, and an accessible design suitable for the visually impaired. What’s more, because the digital feed can be accessed through the cloud, the system can be fully integrated with mobile devices. As a result, residents can interact with visitors remotely, and are even able to provide entry – perhaps for delivery purposes – from anywhere with an internet connection. Similarly, advanced configuration settings can be accessed either with a mobile device or an internet browser.

Streamlined and flexible installation: With a single power supply and featuring flexible wiring options such as ‘daisy chain’, or ‘star connection’, the Hikvision two-wire intercom system can be simply retrofitted in a variety of residential environments. What’s more, because the system uses existing cables, installers avoid the complexities and disruption of drilling new holes or deploying additional wiring. This can save enormous amounts of time and, inevitably, costs.
