Due to convenience and security, the popularity of today’s video intercoms is growing rapidly. This article will highlight some of the most popular features and benefits of these intercoms and differentiate between some of the main types of intercoms.
Door phones are specifically designed to securely identify visitors before they open the door. Room-to-room intercoms, on the other hand, are primarily intended to communicate – typically audio only – from one room of a home or office to another. This is not to say that these categories are mutually exclusive, as there are some intercom systems that can offer both functions; However, most of the time this is not what the application requires.
The basic video intercom system consists of a handset and a 4 inch monitor, a black and white doorbell camera with integrated intercom and a power supply for the handset/monitor. The handset has a Speak, View and often a Door Release button. Today’s cameras typically offer IR illumination that enables night vision through bright LEDs attached to the doorbell camera.
The more advanced home intercom models offer color cameras that are in color during the day and black and white at night. Other features such as time and date stamped 32-frame memory are available to show you who was at the door even when you’re not at home. These intercoms will also be hands-free, so there’s no need to pick up the phone. Monitor controls for brightness, sharpness, speaker volume, and tone volume may not be available on the simpler models. Door status monitoring is also often not available on some economy models.
Consideration is installation
An important consideration is installation wiring and removal. Often the economy intercoms require a 4-wire cable between the monitor and the doorbell station. However, existing doorbell wiring is usually two wires, and this is where the seemingly more expensive intercom system, which only requires two wires, can prove to be the best deal when you add in the work of running and Türsprechanlage pulling new wiring. The premium video intercoms allow up to 300 feet between monitor and doorbell camera using only 2-conductor 18 AWG cable.
A neat feature of some doorphones is the ability to initiate a live display of activity outside your door, even when the doorbell isn’t activated. This is a strong safety and comfort value for many homeowners today. Because most of these video intercoms are easy to install and are surface-mount and weatherproof, many homeowners install them themselves. However, if the remote door opener option is to be used with an electric door opener, which makes installation difficult, a professional locksmith is recommended.
