What are telephone entry systems?

Telephone entry systems are intercoms placed outside an apartment or condo building, that provide ability for visitors to communicate with residents. The visitor can start a call on a tele entry system, which uses a traditional phone line to make a phone call to a resident’s phone. The resident can receive the call, have an audio call and generally press a button to send a signal to release the door remotely.

Landline Usage is declining

Landlines are a dying breed, however still used for many telephone based building entry systems.

36% households still had a landline in 2020, but this number is rapidly dwindling.

landline usage adoption statistics

According to the latest CDC-NHIS survey, fewer than 40% of U.S. households now have a working landline telephone. So, why do you still want to use a telephone line for building entry? The answer is that you don’t. 

Telephone Entry Systems with Video

Most apartment and multi-tenant commercial buildings are moving to video intercoms, instead of telephone intercoms. While telephone intercoms have been common, the new video intercom technology has rendered them obsolete. Video intercom systems are getting popular due to the following reasons:

  • Package theft is a major problem now and video intercom ensures verification of the person before letting them in
  • Video intercoms provide remote door buzzer capability which is very convenient when you are away from home. You can unlock the door from the app anytime
  • Video intercoms are often cheaper to retrofit, since they dont require landline costs, and can be programmed much more easily through a web browser without technical training

Telephone Entry Systems FAQs

What is a telephone entry system?

A telephone entry system allows residents to unlock the door remotely by pressing a button on their landline or mobile phone, depending on the type of system used. The term telephone entry system, sometimes also called an intercom entry system, broadly refers to a variety of telecommunication devices and software used to gain access to a building. Different telephone entry systems can use different backend technologies, but their end goal is the same—to establish voice and sometimes video communication between the front door and the residents or tenants of a building, so that visitors can call their hosts and request entry. 

How do telephone entry systems work?

Legacy telephone entry systems use POTS (plain old telephone service) lines to relay frequency modulated voice signals to hardwire handsets inside the building. The latest telephone entry systems use wireless technologies such as WiFi, LTE and SIP to enable VoIP voice, video and data communications between the entry station and the recipients smartphones as well as a cloud server, which stores the visitor data and runs numerous apps to provide a diversity of benefits; such as remote management, easy scalability, and a variety of access control methods.

How much do telephone entry systems cost?

The price of a simple two-door telephone entry system may start from $1,000 and may go upto $10,000 or more for an all-in-one multi-tenant telephone entry and access control system. This does not include the cost of installation hardware and labor charges.

How do I get a telephone entry system repaired?

Telephone entry systems can develop hardware and software issues when not serviced and upgraded regularly. How you get it fixed would depend on where you bought it from. If it is a fully serviced system such as Swiftlane, you have nothing to worry about. The system will auto detect the problem and alert our technical team, who will resolve the problem remotely or by visiting the site.  Often, it might be cheaper to upgrade to a smart video intercom rather than paying for maintenance and service costs of telephone systems.

Here are some of the things you can do if you need to get a self-serviced telephone entry system repaired.

  • Contact your local installer. They might be able to help
  • Search for contact info of security company that installed the system
  • Consider replacing with a newer system, which might be cheaper to maintain and have more functionality, like video intercom systems

What are the different types of telephone entry systems?

Some confusion prevails over the types of telephone entry systems. Many times, two or more terms are used to describe the same type of system. For example, smartphone and cellular entry systems are also wireless entry systems using different technologies. Single-tenant and multi-tenant entry systems can be IP based, hardwired, cloud-based or cellular systems. 

Swiftlane experts have identified at least 10 different classifications of telephone entry systems that you can find on the market today.

POTS or Landline Entry Systems: These systems use the plain old telephone cables to place calls to the reception or to each individual apartment, depending on whether you are using a single-tenant or multi-tenant system.

IP Entry Systems: IP based entry systems use Ethernet cables, TCP/IP or WiFi broadband to log on to the internet and perform a variety of tasks, such as data transfer, VoIP audio and video calling, remote door operation, cloud computing, and more.

Wireless Entry Systems: Older generation wireless entry systems used radio frequency (RF) to transmit data over the air. The transmissions are captured by receivers and converted back into voice and video. RF is prone to electrical interference and restricted in range. Latest wireless systems use broadband, WiFi, GPS, Bluetooth, and 4G technologies.

Multi-tenant Systems: Multi-tenant telephone entry systems are deployed at the entrance of multi-tenant office buildings and multifamily apartment communities. Visitors can place calls from the entry station to each individual apartment unit or office suite. The capacity of a multi-tenant telephone entry system may range from 2 or 4 units to multiple entry phones and hundreds of units across multiple buildings.

Based on the technology used, multi-tenant intercom systems can use telephone cables or modern wireless technologies to relay voice, video, and data between the entry phone and multiple landline or mobile phones in each unit. 

Single-tenant Systems: These systems are designed for single-family homes and small offices. A single main door or gate phone can place calls to an indoor handset and also to a certain number of mobile phones, depending on the technology.

Cloud Based Entry Systems: The latest generation building entry systems make use of cloud-based software to connect visitors with residents via VoIP and LTE video and audio calling. The entry station is connected to the cloud and can run various apps to execute a variety of functions, such as remote door release, access control, video surveillance, and more. 

Cloud managed telephone entry systems do not require maintenance or upgrades at the users end. Most of these systems can be self-managed by the user and are available for minimal capital expenditure and easy pay-as-you-go pricing.

Cellular Entry Systems: These systems use cellular technologies such as GSM and LTE to route calls to the recipient’s mobile phone. A SIM needs to be inserted in some of the models and you have to keep it loaded. Some POTS models can be converted to Cellular by installing additional hardware and an LTE switch.

Telephone Entry Systems with Cameras: Cameras can be added to many telephone entry systems that we have discussed in this article. This gives the tenants or residents more security and convenience as they can see the person who is calling. Telephone systems with cameras also store photo logs and also send them to designated mobile numbers via MMS or mobile app. Latest video intercom entry systems such as Swiftlane include built-in HD cameras and can make video calls to the recipient’s smartphone through proprietary mobile applications.

Intercom Entry Systems: The term intercom entry systems is used synonymously with telephone entry systems, simply because an entry telephone is basically an intercom. Today’s intercom entry systems reside in the cloud and provide audio and video calling capabilities as well as remote management from mobile apps and browser interfaces.Integrated Entry Systems: Integrated or smart entry systems join multiple technologies to create a unified building access control and security system. Some of the functionalities that integrated building entry systems provide can include audio and video calling, mobile app and browser unlock, keycard access, smartphone access, and face recognition access. Being cloud based, these systems can be integrated with a myriad of cloud apps such as Active Directory, fire alarm systems, video surveillance systems, and more. The best thing about these latest-generation systems is you and your staff can easily manage and customize them using native mobile apps and browser interfaces.
