What about wired or wireless intercom systems?

Many of our customers seek our expertise when it comes to installing a wired system VS a wireless system. What are the advantages and disadvantages? Below we list some basics to help you figure out what the best system for your needs.

Hardwired intercom systems include an entry panel at the entrance to the building/business, and an indoor unit/monitor at each apartment (or an office). These systems  are usually more reliable and require less maintenance. You should expect very few issues when installing a hardwired intercom system compared to a wireless intercom system. These systems can offer HD video, high quality audio, fast communication between the door and the tenant, and door buzzing. For larger buildings, they may include other functions such as doorman call, 2nd camera viewing, light switching in hallway and more. When considering an upgrade of existing multi-family intercom system, often more than not, we can use the building’s existing wiring for the upgrade – which saves you a lot of money on the labor.

Wireless buzzer intercom systems include an entry panel only, and no units in the apartments. These systems are connected to a phone line or internet line and provide audio or audio/video communication to residents’ landline or mobile phone devices. Like with anything high-tech, there are more chances for issues and faults with these systems. The convenience of being able to answer the door using an app on your phone from wherever you are comes at a cost of more maintenance. As an upgrade, this is a very cost effective option since it saves you money on installing a monitor at each apartment. We usually recommend this solution to larger multi-residential buildings.  

Hybrid IP intercom systems include both wired units and wireless connectivity using mobile apps. These systems are usually more expensive and allow you to enjoy the best of both worlds.

“The communication between the apartment and the door unit had broken because of some issue in the intercom. I needed to have it repaired promptly. I called them and had their technician at the exact-time. He started his work and resolved the mess. Based on my experience I highly recommend them for accurate Intercom repair.”    –Lena Decoteau
