What are the Different Types of Entry Systems and Their Purposes?

A door entry system, also known as an access control system, is commonly used in residential and commercial settings to control access to and from a restricted area, building, or zone, especially in multi-tenant or multi-user settings. Many door entry systems are available, ranging from PIR-activated automatic doors to PIN code keypads and contactless proximity readers.

What are the Types of Door Entry systems?

There are several types of door entry, access, and door intercom systems to choose from, depending on the system’s criteria and concerns. Check out the buyers guide to front door entry systems so that you may select the ideal one for you.

Audio Entry Systems

This straightforward procedure is dependent on verbal confirmation. It consists of a base station and a remote station. Both were installed at the appropriate access door. People can inform those at the base station by pushing the ‘doorbell’ button on the door station. The base station answers by conversing with them verbally. To open the door, press the release button on the base station. The cost of a single audio intercom system is usually low. The system’s wiring is simple. They’re easy to set up and keep up with.

Video Entry Systems

It’s the equivalent of a sound-only system. It still has a camera so that the resident or security officer may check the visitor’s identification. A video intercom system has a base station and one or more distant stations like an audio intercom. The answering machine will have a screen, and the door stations will have a camera embedded in them. Smartphones are increasingly being used for face-to-face video intercom discussions and door intercom system unlocking.

When the unit is activated, it alerts the homeowner or security office that someone is at the door. The visitor can then use their voice to speak with the person at the base station. A multi-door application is activated by pressing a button. The base station can see the image of the guest. Instruct the guest to go closer or farther away from the camera for a better shot.

Keypad Entry Systems

One of the most prevalent door entry systems is a keypad door station, which requires a PIN to be manually input to gain access. This door entry system could be as simple as a door lock, or it could be linked to an electronic access control system that verifies the pin code’s validity. Keypad systems may use a single PIN code for all users or assign unique PINs to each user, depending on the technology used.

Wireless Entry System

The simple standalone wireless intercom system is commonly used in residential and small commercial applications. The system consists of a wireless base station and a remote/door station. When the doorbell button on the door station is pressed, the person at the door is notified. They can communicate verbally with the person who answers from the base station.  The advantage of a freestanding wireless door entry system is that it does not require any running cable.

There are various door entry, access control, and door intercom systems to choose from, each with its own set of needs. The type and scale of the program, the quantity, and demographics of users, the required security levels, and system adaptability are just a few examples.
