Site Assessment

There are four primary types of security intercom systems for residential and commercial use. These include:

Hard-Wired Intercom System: This commonly-used intercom system is usually installed by a builder when a property is newly constructed. Typically hidden inside the walls, this type of intercom system is generally more resistant to wear and tear and external interference. And the audio signal tends to be better than other types of intercom systems.

Carrier Current Intercom System: Less expensive than hard-wired intercom systems, this type of intercom is integrated into the electrical system of a home or commercial building. While a carrier current intercom system is easy to install and maintain, audio quality is generally lower than what a hard-wired intercom system can provide.

Wireless Intercom System: A wireless intercom uses different types of radio frequencies to send intercom signals within your home or business. Wireless systems also tend to be less expensive than hard-wired intercom systems, are usually battery powered, and typically require only very simple installation.

Automatic Gate Entry Intercom System: This type of intercom system allows you to open an access gate on your property whenever a visitor arrives. You don’t need to be physically present in order to open or close the gate. Automatic gate entry intercom units are usually equipped with a video security camera and an indoor video display with audio, to enable you to see and communicate with whoever is at your gate.

Voice Only Intercoms

Need to check on what the kids are doing? Or call everyone to the dinner table? Or summon your employees for an all hands meeting? Instead of texting everyone in the house or relying upon mass email notifications, having an intercom system can be a much more efficient solution for communicating with family or coworkers, no matter where they are in your home or office. We install a wide variety of voice intercom systems to meet any need.

Video Intercoms

Conventional audio-only intercom systems are quickly becoming a thing of the past. A video intercom system provides significant security and convenience benefits over traditional intercoms, including:

  • Mobile apps that enable you to answer your doorbell from your smartphone, tablet or PC, from anywhere in the world
  • High-resolution monitors with hands-free or push-to-talk options
  • Pan, tilt and zoom capabilities to eliminate blind spots
  • Infrared sensors for crystal clear night vision
  • Recording capabilities to store images, including a time stamp to see when visitors arrived
  • Integration with video security or smart home systems
  • The ability to link multiple entrances to a single intercom system

Music and Voice Intercoms

A music and voice intercom system combines room-to-room communication with a whole home audio system. Intuitive room stations can deliver music or voice chat to a single intercom station, or broadcast your chosen audio across your entire home or place of business. Music and voice intercoms typically also include door stations to allow communications with visitors, as well as door release mechanisms for home or business access control. Our expert technicians can explain all of your options, to help you decide on the perfect music and voice intercom system for your home or business.

Doorbell Intercoms

Knowing who is at your door, without opening the door, provides safety and a sense of security for you and your family. A doorbell intercom system enables you to easily find out who is outside of your home – whether or not you are at home – and to speak with them at the touch of a button. This type of intercom system works well for accepting packages, deterring unwanted solicitors, and scaring off potential intruders before they have the opportunity to access your home.

Installation and Configuration

T7 Video Security’s intercom technicians understand that your time is valuable, and that a system installation can be unsightly and potentially impact your business operations. So we will do our best to minimize any disruptions and work quickly to install your new system.

We’ll work with you to determine the best time for your installation, even if it is outside of regular business hours. Before your installation begins, our technicians will provide you with a reasonable expectation of how long the installation process should take.

We will begin by installing the entry panel(s), toning and testing the cables to ensure that they can carry the necessary voltage before the intercom station is installed, installing the intercom station, installing the head and equipment, then installing the power supplies and modules. We’ll then configure your system settings.

More than anything, we want to ensure that you’re comfortable with your new intercom system before we leave. That’s why we review with you all aspects of how your system operates, and make sure that you know where to access information on how to operate and troubleshoot your system. Our technicians will not leave until you are satisfied with your installation, and have a solid understanding of how your new intercom system works.

System Documentation

When your installation is complete, we’ll provide you with a diagram of your new system’s intercom station(s), product documentation for all of the equipment we have installed, instructions on how to use your system’s features, along with a detailed listing of your default system settings in case you ever need to reset your system.

You may even be able to use your system documentation to help reduce your homeowner’s or business insurance policy premium. Some of our clients in the Charleston, SC area have been able to get discounts from their insurance company due to having the additional security of a professionally installed intercom system in their home or workplace.

Maintenance and Support

At T7 Video Security, we offer expert maintenance and support for your intercom system. No matter whether you have a simple question that you just cannot seem to figure out, or a larger-scale issue that requires immediate attention, our professional customer service team is here for you. We first will work to troubleshoot the issue with you over the phone, and if we can’t, we’ll dispatch a trained intercom technician to come out to your home or place of business at your earliest convenience, so that they can address the problem. Our customer service is what sets us apart from other security companies in the Charleston, SC area.
