A door entry system is defined as a device that allows people to enter a building through a door.

A door entry system, also known as an access control system, is 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 applications. Many door entry systems are available, including PIR-activated automated doors, PIN code keypads, and contactless proximity scanners.

The Kinds of Door Entry Systems 

There are various door entry, access, and door intercom systems to choose from, depending on the system’s requirements and concerns. Explore the different door entry systems to choose one which is right for you.

Audio Systems

This straightforward method is solely based on verbal confirmation. It consists of a base station and a remote station, both located at the appropriate access door. Those at the base station can be notified by pressing the ‘doorbell’ button on the door station. They answer by having a vocal conversation with the base station. Release the base station’s release button to unlock the door. In most cases, a single audio intercom system is affordable. The system has a simple wiring setup. The door entry systems are easy to put together and keep up.

Video Systems

It’s akin to having a sound-only system. It still has a camera in it, so the resident or security official may check the visitor’s identification. A video intercom system has a base station and one or more distant stations, similar to an audio intercom system. The answering machine will feature a display screen, and the door stations will have a camera embedded in them. Smartphones are increasingly being used for face-to-face video intercom chats and intercom door unlocking.

Keypad Systems

One of the most prevalent door entry systems is a keypad door station, which involves manually entering a PIN to get access. This door entry system could be a conventional door lock or linked to an electronic access control system that verifies the pin code’s validity. Keypad systems can use a single PIN code for all users or assign several PINs to each user, depending on the technology used.

Wireless Systems

The simple wireless intercom system is frequently used in residential and small commercial applications. The system comprises two components: a wireless base station and a remote/door station. When the doorbell button on the door station is pressed, it alerts the person at the door. They can communicate verbally with the person who answers from the base station. There is no need for a running connection with a standalone wireless door entry device. They’re easy to put together and maintain. You may need to reinforce and repair your door to ensure your safety and your belongings.



A door entry system can function as a simple lock or as a doorbell, resident directory, and intercom system, allowing you to have complete control over who enters your facility. They’re typically used to unlock and open motorized gates, barriers, and car parking entrances, but they’re also employed to let people in through internal and outdoor doors. There are many different 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 number of users and their demographics, the required security levels, and system adaptability are just a few examples.
