TYPES OF DIGITAL DOOR LOCKS
There are different types of digital door locks available in the market, they are,
- keypad locks
- smart locks
- biometric locks
KEYPAD LOCK
Keypad locks require users to input a code to unlock the door. Some models come with a touchscreen interface, while others have physical buttons. Keypad locks are typically battery-powered and can be easily programmed to add or delete user codes.
A keypad lock is a type of digital door lock that requires a user to enter a numeric code on a keypad to unlock the door. These locks typically have a touchpad or membrane keypad that allows the user to input a code, which is then verified by the lock's internal electronics. Keypad locks can be used on residential or commercial doors, and they offer several benefits such as eliminating the need for a physical key, providing multiple user codes, and allowing for remote access control. Keypad locks can be battery-operated or hardwired, and some models can be integrated with smart home systems for added convenience and security.
KEYPAD LOCK WORKING
A keypad lock works by using an electronic circuit and an electric motor to control the locking mechanism of the door. When the user enters a correct code on the keypad, the lock's electronics will recognize the input and send a signal to the electric motor to unlock the door.
The keypad itself typically has a set of buttons, usually numbered 0-9, along with other buttons for "enter", "cancel", and other functions. The user inputs the correct code sequence by pressing the appropriate buttons in order. The lock's electronics will compare the entered code to a pre-programmed list of valid codes, and if the code matches, the lock will release the bolt or latch that secures the door.
Some keypad locks have additional features such as multiple user codes, temporary codes, time-based access control, and remote access control. Some models can also be integrated with other security systems, such as cameras or alarm systems, to provide a more comprehensive security solution. Keypad locks can be battery-operated or hardwired, and the installation process can vary depending on the specific model and type of door.

Keypad locks can store multiple user codes, which can be useful for granting access to family members, friends, or employees. This allows users to control access to a building or room more easily.
👉Access logs:
Some keypad locks can store access logs, which can be useful for monitoring access to a building or room. This can help to identify any unauthorized access attempts or suspicious activity
DISADVANTAGES OF KEYPAD LOCK
👉The limited number of codes:
Many keypad locks have a limited number of codes that can be programmed into them, which can be a disadvantage if multiple people need access.
👉Not suitable for all weather conditions:
Some keypad locks may not be suitable for all weather conditions, particularly extreme cold or heat, which can affect the battery life and operation of the lock.
SMART LOCK
Smart locks can be controlled remotely through a mobile app or integrated with other smart home devices. They offer advanced features such as voice control, auto-locking, and geofencing, which allows the lock to automatically unlock when the user is within a certain range.
SMART LOCK WORKING
A smart lock is a type of digital door lock that uses wireless communication and advanced technology to control access to a building or room. The operation of a smart lock depends on the specific type and model, but in general, it works as follows:
- Authentication: When a user approaches the door, the smart lock's wireless receiver detects the user's mobile device, key fob, or another authentication method. The user's identity is verified by the lock's internal electronics, which compare the authentication credentials to a pre-programmed list of authorized users.
- Authorization: If the user is authorized to access the door, the smart lock's electronics will send a signal to the lock mechanism to unlock the door. Depending on the specific model, the lock may use a motorized bolt or latch to unlock the door, or it may use an electromagnetic field to release the lock mechanism.
- Remote access: Some smart locks allow users to control access to the door remotely, using a mobile app or other software. This allows users to lock or unlock the door from a distance, without physically being present at the door. Remote access can be useful for granting access to guests or service providers, or for monitoring access to a building or room.
- Integration: Many smart locks can be integrated with other smart homes or security systems, such as cameras or alarm systems. This allows users to create a more comprehensive security solution that can monitor and control access to a building or room, as well as detect and respond to security threats.
ADVANTAGES OF SMART LOCK
Smart locks eliminate the need for physical keys and provide a more convenient way to lock and unlock doors, particularly for those who frequently forget their keys or need to provide access to others when they are not home.
Smart locks allow users to lock and unlock their doors remotely, which can be useful for providing access to family members, friends, or service providers when the user is not at home.
Some smart locks offer advanced security features such as biometric recognition, which can be more secure than traditional locks that rely on physical keys.
DISADVANTAGES OF SMART LOCK
Smart locks may require more maintenance than traditional locks, particularly if the electronic components or batteries need to be replaced.
Smart locks can be more expensive than traditional locks, particularly if they include advanced features such as remote access or biometric recognition.
BIOMETRIC LOCKS
Biometric locks use fingerprint or facial recognition to grant access to authorized users. They are considered to be the most secure type of digital door lock as they require physical verification of the user's identity.
BIOMETRIC WORKING
Biometric locks are a type of digital door lock that uses unique physical characteristics, such as fingerprints, facial recognition, or iris scans, to authenticate and authorize access. The operation of a biometric lock depends on the specific type and model, but in general, it works as follows:
- Enrollment: The first step in using a biometric lock is to enrol the user's biometric data into the system. This typically involves capturing a high-resolution image of the user's fingerprint, face, or iris, and storing it in the lock's internal database.
- Authentication: When a user approaches the door, the biometric lock's sensors capture an image of the user's biometric data and compare it to the stored data in the lock's database. If the captured data matches the stored data within an acceptable margin of error, the lock's electronics will send a signal to the lock mechanism to unlock the door.
- Authorization: If the user is authorized to access the door, the smart lock's electronics will send a signal to the lock mechanism to unlock the door. Depending on the specific model, the lock may use a motorized bolt or latch to unlock the door, or it may use an electromagnetic field to release the lock mechanism.
- Remote access: Some biometric locks allow users to control access to the door remotely, using a mobile app or other software. This allows users to lock or unlock the door from a distance, without physically being present at the door. Remote access can be useful for granting access to guests or service providers, or for monitoring access to a building or room.
