Features and Benefits of Today’s Door Intercom Systems
Due to convenience and security, the popularity of today’s video intercoms is growing rapidly. This article will highlight some of the more popular features and benefits of these intercoms and distinguish between some of the major types of intercom systems.
Door intercom systems are specifically designed to Alarmanlage Haus safely identity visitors before answering the door. Room to room intercoms, on the other hand, are principally designed to communicate–typically audio only–from one room of a house or office to another. This is not to say these are mutually exclusive categories because there are some intercom systems which can offer both capabilities; however, most of the time this is not what the application demands.
The basic video intercom system will consist of a handset and 4-inch monitor
Black and white doorbell camera with integral intercom and a power supply for the handset/monitor. The handset features a Speak, View, and often, a Door Release button. Today’s cameras usually offer IR illumination, which provides night vision through bright LEDs that are mounted on the doorbell camera.
The more advanced home intercom models will offer color cameras, which will be color during day and black and white at night. Other features such as 32-picture memory with time and date stamp are available to show you who was at door even when you are not at home. These intercom systems will also be hands-free so there is no handset to pick up. Monitor controls for brightness, sharpness, speaker volume and chime volume may not be available on the more basic models. Door status monitoring is also often not available on some of the economy models.
An important consideration is installation Alarmanlage wiring and distance. Often the economy intercom systems will require a 4-conductor cable between the monitor and the doorbell station. However, existing doorbell wiring is usually two wires, and here what appears to be the more expensive intercom system that only requires two wires may turn out to be the best deal when you add the labor in to run and pull new cable. The premium video intercom systems will allow as far as 300 ft. between monitor and doorbell camera with just 2-conductor 18 AWG wire.
A nice feature on some door intercom systems is the ability to initiate a live viewing of activity outside your door even when the doorbell is not activated. This is a strong safety and comfort value for many homeowners today. Since most of these video intercom systems are simple to install and are surface mounted and weatherproof, many homeowners install these themselves. If, however, the remote door release option will be used with an electric door strike, which does complicate the installation, a professional locksmith is recommended.
