Choosing a Password Door Lock
A password door lock provides enhanced security for your home without compromising on convenience. These locks can be programmed to issue temporary codes to repair professionals, babysitters and dog walkers. They are also a great solution for homes with multiple residents.
The microcontroller accepts the password from keypad module and compares it with the stored one. Then it drives the dc motor to open/close the door.
Keypad Locks
Keypad locks use a keypad to allow access, rather than requiring the user to input a physical key. The keypad has a number of buttons that are labeled with numbers or letters, as well as a clear space to enter the PIN code. A light or other signal indicates when the correct code has been entered. Most keypad locks offer a security feature that will disable the lock for 15 minutes after several incorrect codes are entered.
These keypad locks can be installed on almost any door, and they don’t require any major changes to the door or frame. They also have the added benefit of eliminating the need for keys, which can easily be lost or stolen. Instead, children, guests and service providers can be given temporary codes to use the lock.
There are two main types of digital keypad locks: standalone and those that are part of a home or commercial security system. Standalone models use standard batteries as their power source and must be changed on a regular basis to ensure continued operation. These locks typically connect to the internet, which allows owners to remotely control their lock from a smartphone app. Some of these apps are compatible with voice assistants like Amazon Alexa and Google Assistant. They can also be used to remotely lock or unlock the door, which is helpful for vacation rentals and other rental properties where the owner manages property from a distance.
Digital Password Locks
Digital password locks let you unlock your door with a 6-digit code. They’re especially useful for families with kids or house help. Some models password door lock let you give access to people who work at fixed times, such as carers or nurses. You can also remotely change your lock code in case you lose or break your key.
They can be hard to remember, though. If you’re not careful, a bad habit can form where you type the same access code every day, which can cause the digital lock to wear out faster than normal. If you tend to forget passwords, consider a model with physical buttons for code entry rather than a touchscreen.
The circuit consists of a PIC (Peripheral Interface Controller) microcontroller 18F4552, which is interfaced with a matrix 4A–4 keypad and a 16A–2 LCD to act as user interface. The microcontroller checks the input from the keypad and confirms that the entered code is correct before activating the electrically actuated lock. The microcontroller can also be used to change the current password through keypad instruction.
You can also set up different types of access for various people and times, which makes it easy to keep track of who’s coming and going. This feature is particularly helpful if you have contractors in your home working at fixed times, and it can also help you avoid forgetting to lock up after leaving the house.
Fingerprint Locks
Fingerprint door locks allow people to unlock their doors without a key or code. They scan and record a person’s fingerprints and compare them to a database of known prints to grant access.
They’re a good choice password door lock for homes or small businesses that want to prevent theft and monitor who’s coming and going. Most work with apps to provide remote functionality and connect to a smart home system for added security.
Compared to password door locks, they’re more secure and difficult to hack. That’s because there is no code to guess or hack, and they are difficult to bypass. However, there are some things that can interfere with the operation of a fingerprint lock, such as delayed fingerprint recognition and a damaged fingerprint scanner.
When buying a fingerprint lock, choose one with a high False Rejection Rating (FRR) and a low False Acceptance Rate (FAR). FRR refers to how often the reader rejects an unqualified fingerprint and FAR refers to how frequently it allows in a verified fingerprint. You also want to make sure the lock has a durable and reliable battery, such as a lithium battery. This will help ensure a longer lifespan for the fingerprint smart lock.
Commercial Password Locks
A commercial password lock works similarly to a keypad lock, but with additional security measures that may include an audible response to each button press or the ability to authenticate users by requiring them to swipe a token, scan their fingerprint, or otherwise interact with a physical sensor. These types of locks are typically found in businesses and other commercial establishments where high levels of security are required to prevent theft or property damage.
These kinds of electronic locks can be more reliable than traditional keyed locks because they are less susceptible to the wear and tear associated with repeated use. They also offer increased flexibility for businesses, such as allowing them to set up different codes for different employees or temporary workers. However, they are still vulnerable to hacking, so it is important to keep up with firmware updates and protect your WiFi network from outside attacks.
Password door locks are becoming increasingly popular in homes and businesses due to their increased reliability and convenience. This growth is fueled by the demand for security and safety in residential and commercial areas, rising investment in digital solutions, and growing awareness of cybersecurity threats among end-users. The global password door lock sales market is segmented by Type (Digital Password, Fingerprint Password), and By Application (Household, Commercial, Others). North America is the leading revenue generating region in this market due to its high spending power and penetration & connectivity rate.
