Key takeaways:

  • A telephone entry system is an electronic device that empowers building residents to communicate with and grant access to their visitors.
  • While they enable communication, telephone entry systems lack cameras, they can’t be managed remotely, and they require telephones, which many modern residents lack.
  • A video intercom is a modern take on the telephone entry system and the best replacement for your outdated entry system.

5 telephone entry systems

If you intend to purchase a telephone entry system, make sure you choose one worth the money.

Here are five telephone entry models to consider:

  1. Doorking
  2. Kantech
  3. Mircom
  4. Linear
  5. Select Engineered Systems

 

1. Doorking

Doorking is perhaps the most well-known telephone entry system provider in the industry. Based in Southern California, Doorking (or DKS) has been selling phone entry systems since 1948.

DKS telephone entry models have a traditional, simple design with few features or bells and whistles. These systems are installed on POTS phone lines, so they require traditional telephone wiring. However, Doorking does offer cellular telephone entry models. But to enable cellular service, you must purchase the DKS Cellular Connection Box, which is sold separately from the entry system.

Features of Doorking systems vary by model but may include:

  • LED tenant directory
  • Ability to store thousands of names and phone numbers
  • Programmable via PC (systems include programming software)
  • Tamper alert switch
  • Weather sealing

According to a January 2022 price sheet, Doorking systems range in price from $1,496 to $7,040 for hardware (depending on model).

Remember you must also budget for installation fees and possible service connection costs. A VoIP adapter costs $180 while cellular service connection plans range from $1,200 to $1,700.

2. Kantech

Kantech is a Tyco Security Products company founded in 1986 that designs and sells various access control solutions that are ready to use right out of the box. The company’s product lineup ranges from security services and software to door controllers and telephone systems.

The Kantech Telephone Entry System (KTES) is a basic building entry system designed for apartments, gated communities, condos, offices, and industrial properties. Visitors can call and communicate with a tenant directly through the KTES, at which point the tenant can grant or deny entry directly from a landline telephone or cell phone.

Property staff can remotely manage their building’s KTES using Kantech’s EntraPass software, which appears to be sold separately and may only be compatible with Windows operating systems.

Features of the Kantech telephone entry system:

  • Compatibility with Kantech door controllers.
  • Comes with a pared-down version of EntraPass management software. So, you may have to purchase the full software package for access to all features.
  • Use as a stand-alone system or integrate with an existing access control system.
  • Vandal- and weather-resistant stainless steel casing.
  • One phone line supports up to five units.
  • 4-line, 20-character LCD screen.
  • Directory capacity of 3,000 tenants.

Types of telephone entry systems

Originally, apartment telephone entry systems were designed for landline phones. But now that cellular towers are everywhere, some newer entry phone systems have started offering cellular connections. And other features are being added to phone entry systems as technology advances.

As a result, there are a few different types of entry systems.

Some of the most common types of systems include:

 

Landline systems

The first systems were introduced in the time before cell phones, when you had to connect your telephone to a phone jack in the wall. They were designed to let visitors alert residents of their arrival, and let residents unlock the front door without going downstairs.

When receiving a call placed through the telephone entry model, residents with landline phones answer it just like they would a normal phone call. They can hear and speak with their visitor. To unlock the door for their guest, they simply press ‘9.’

 

Cellular telephone entry systems

Until recently, these systems required a dedicated phone line. But landline phones are dying out — as of now, only 68.9 million people have a functional landline. To adapt, many providers have started connecting their telephone entry models through a cellular service (e.g Verizon, AT&T, T-Mobile, etc.)

However, many cellular entry systems require customers to purchase and install a cellular connection box to enable cell service. And since most cellular-enabled systems aren’t cloud-based, they can’t offer features like video calling, delivery PINs, or a mobile app.

 

Telephone entry systems with cameras

These days, multifamily residents demand tech-powered apartment amenities. Recognizing that these systems can’t meet that demand, some access control providers have started adding cameras to their tele entry systems.

Adding a camera to a telephone entry model improves security at the building by offering residents a way to see visitors in addition to speaking with them. A modern telephone entry systems with camera offers in-unit hardware with screens to display video footage. Others have started developing mobile apps where residents can view video footage of visitors from their smartphones.

 

Wireless telephone entry systems

A wireless telephone entry system enables communication between visitors and residents without the wiring required of traditional systems with phone lines. As such, most wireless phone entry systems operate with cellular networks.

Remember: You’ll need to pay for a cellular service plan to enable calls from a wireless entry system. So, you’ll have to factor that monthly expense into your budget.

 

VoIP telephone door entry systems

A VoIP telephone entry system uses VoIP technology for voice communication rather than POTS telephone lines. VoIP stands for ‘voice over internet protocol.’ These systems transfer data over the internet rather than telephone wires.

VoIP phone entry systems require an internet connection and possibly TCP/IP and VoIP adaptors.

 

Cons of telephone entry systems

A tele entry system isn’t the best solution for your property because it falls short in many ways.

Telephone entry models have a few limitations that you should consider:

  • They require a telephone line to make outgoing calls. This means you’ll have to pay a monthly fee for that line. It also means that if your resident has an out-of-state phone number, your system will be making a long-distance call to that resident even though they live in your building. These costs add up quickly.
  • You can’t manage a telephone entry model remotely. For example, adding a tenant to the directory requires you to go onsite and program that person into the system. The same is true if you want to remove that resident. This is a highly time-consuming process when you factor in your average turnover rate and the time it takes to travel to each building you own or manage.
  • They lack cameras. Since the data required to transfer video is too large for a telephone line to carry, these systems cannot have built-in cameras. As a result, residents and building staff can’t see who they’re letting into the building.

Thankfully, technology has improved significantly since the invention of the entry system. Today, we have better entry solutions available.

 

How do you use an entry phone?

To use an entry phone as a visitor, you simply use the entry phone to contact a tenant and have them grant access. To use an entry phone as a tenant, you can simply verify the identity of the guest, then press ‘9’ on the keypad to grant entry.

 

How much does a telephone entry system cost?

These systems cost anywhere from about $1,000 to $7,000, not including the cost of installation or maintenance fees.

Hardware costs vary based on the system’s functionality. For example, basic phone entry systems that lack many features and limit the number of tenants you can add may sell at the lower end of the price range. In contrast, a more modern cellular door entry solution will cost more.

Installing a telephone entry system may cost thousands of dollars since most require extensive wiring. If you’re installing a system with in-unit hardware, you’ll also have to factor in the cost of purchasing and installing those devices. Additionally, cellular telephone entry systems may require you to purchase and install a cellular connection box at your property.

Ultimately, even a lower-end telephone entry system can cost a lot more than you think since the installation, wiring, and hardware costs add up quickly.
