telephone entry system with camera

 

If you own or manage a property – whether residential or commercial – you know that every building needs a property access system. But how do you verify a visitor’s identity before providing them with building access? Installing a telephone entry system with a camera is one option.

For over a century, telephone entry systems have been the most popular access control system. Soon after Alexander Graham Bell invented the telephone, entry phone systems became the standard by the early 1900s. And by the 1980s, after electronic cameras emerged in 1975, these entry systems came with cameras, adding an extra layer of security to property access.

But times have changed drastically since then. Read on to learn more about telephone entry systems with video and discover how they work, as well as why a more modern entry system may be worth the investment.

This post covers:

 

What is a telephone entry system with a camera?

A telephone entry system with a camera is an electronic device that enables communication and property access between residents and visitors. Starting in the 1980s, telephone intercom manufacturers started offering systems with cameras. The camera can either be purchased and installed separately or built into the entry system.

Unlike traditional telephone door entry systems, those with cameras allow the resident to see the visitor either on an in-unit screen or from their smartphones. Of course, it’s only in recent years that the majority of people started owning smartphones. So, most telephone entry systems with cameras are only compatible with in-unit hardware.

A telephone entry system operates via a traditional telephone line and requires hardware installed at the property’s entryway and a telephone to receive calls. If the system includes in-unit hardware, residents can view video footage and communicate with visitors through those devices. If the entry system is mobile app-based, residents view video footage from their smartphones and press a button to grant visitor access.

Phone entry systems with video are usually installed at gates or doors to allow tenants and authorized visitors access.

You may find this type of entry system installed at:

  • Gated community main entrances
  • Student housing entrances
  • Senior/assisted living communities doors
  • Hospital building entries
  • Multifamily apartment building entry doors
  • Commercial building entrances
  • Retail building doors

 

The origins of video telephone intercoms

Although deemed controversial, security cameras (CCTV) invented and used in World War II may have inspired the idea to include cameras on telephone entry systems. The U.S. was relatively slow adopting video intercom systems, especially since families rarely felt the need to even lock the front door. However, soon after the war ended, Americans became more sensitive to security needs.

How do telephone entry systems with cameras work?

When a visitor or a delivery person needs access to a building, they look up the tenant using the telephone entry system’s directory. When the visitor finds the tenant, they press a button or dial a code. Then, the camera turns on and the entry system calls the resident’s registered phone number.

When a tenant receives a call, their in-unit device shows them video footage of the visitor. The resident and the visitor can talk to each other, but only the resident can see the visitor. Since the entryway hardware lacks a screen, the visitor cannot see the resident. If the resident wants to grant access, they press ‘9’ – or a marked ‘open’ button – to unlock the door or gate for the visitor.

Residents must register their landline or mobile phone number for the whole system to work. And most telephone entry systems with cameras also require indoor hardware to be installed.

Telephone entry with a camera requires five components:

  1. Outdoor hardware with a camera installed at the front door or gate. Some cameras are motion-sensor, while others turn on once a visitor initiates the call.
  2. In-unit display screens on which residents can see the video footage of a visitor.
  3. A door release system that unlocks the door when the resident presses ‘9’ on their phone or a designated button.
  4. Power supply.
  5. Telephone wiring and/or cellular connection.

 

Two types of telephone entry systems with cameras

One thing’s for sure: Technology has advanced significantly since the 80s. Since the invention of camera cell phones in 2000, the world has forever changed its views on the purpose of video. And the advent of smartphones further accelerated the use of video in everyday life. Although telephone entry systems with cameras were initially designed to be used with landlines and in-unit hardware, some newer models are compatible with smartphones.

The two types of telephone entry with a camera are:

  1. Landline systems
  2. Cellular systems

 

1. Landline systems

A landline telephone entry system can either operate with in-unit hardware or the tenant’s own landline telephone. In-unit devices for landline telephone entry systems with cameras come with a display screen and a telephone or dialing pad. Another way these systems work is to use a computer as a monitor and a separate landline phone to talk to the visitor.

In both landline systems, the visitor presses a button on the entry system to call the resident. Then, the resident answers the phone like a typical call, and live footage of the visitor appears either on the in-unit device or computer screen. They can see and communicate with the visitor. Finally, to unlock the door for their guest, the resident presses ‘9’ or a designated door release button.

 

2. Cellular systems

When was the last time you used a landline phone? Probably very long ago! Needless to say, landline phones are dying out as smartphone ownership rises. As such, entry systems have also evolved. In recent years, many camera telephone entry systems are accompanied by cellular connection boxes to enable users to control access with their smartphones.

However, those cellular connection boxes are an added cost and don’t work with all telephone entry systems. Especially since most cellular-enabled systems are not cloud-based, they might not allow for residents to view video footage from their smartphones, defeating the purpose of cellular phone entry systems with video.

Limitations of telephone entry systems with cameras

Although camera-enabled telephone entry systems are indeed an upgrade from older models, they still have limitations.

Here are three significant drawbacks of telephone entry systems with cameras:

  1. Require a telephone line
  2. Aren’t cloud- or internet-based
  3. Don’t have robust video capabilities

 

1. They still require a telephone line

Telephone entry systems with cameras can’t be standalone devices. They still need to be wired to a telephone line, for which you need to pay a monthly fee.

Even if your residents connect their cell phones to the entry system, you could still face an expensive problem. If residents have out-of-state cell numbers, long-distance call fees will apply.

The alternative option is to install in-unit hardware in each residence and run building-wide wiring. However, all that is costly and still isn’t suitable for modern living.

 

2. They aren’t cloud- or internet-based

Telephone entry systems only offer one-way video, which means only residents can see live video footage. Since the data required to transfer video both ways is too large for telephone lines to carry, the camera only works one way.

Also, because the system is not connected to the internet, property staff can’t manage or update the directory remotely. You’d need to go onsite to input residents’ information manually and to remove it when they move out.

 

3. They don’t have robust video capabilities

As mentioned above, telephone entry systems with cameras can’t transmit video data to both parties. Residents can see visitors, but visitors can’t see residents. Also, there is no way to record and save video trails – a top security feature – on a phone-based entry system.

Telephone entry systems with cameras vs. video intercom systems

Telephone entry systems with cameras are outdated – at most, they’re a humble effort to modernize a worn system. Meanwhile, video intercom systems are specifically designed for modern living. They enhance security and convenience for both residents and property staff.

 

Feature Cloud-based video intercom systems Phone entry systems with cameras
Two-way video calling capability Yes No
Smartphone app-based door release and video chat Yes No
Video audit for every entry event Yes No
Virtual keys or delivery PINs for authorized guests Yes No
Ability to open doors for guests without going to the lobby Yes Yes

 

Why video intercom systems are better

We’re living in the 2020s, not the 1980s. So, it’s time to upgrade your building’s entry system to suit the new digital age. Today, people do everything on their smartphones – start car engines, order food delivery, shop for groceries, turn on and off lights, cash checks, and so much more. ButterflyMX’s video intercom makes property access simple, convenient, and more secure than ever before.
