A Simple Guide to Setting Up Fingerprint Door Locks
Fingerprint door locks have become increasingly popular due to their security and convenience. These locks can be easily set up with a minimum of technical knowledge. Once your finger is placed on the scanner, the difficult part of setting a new fingerprint is taken care of. This process is repeated every time you want to grant someone access. When someone attempts to use their fingerprint, the system checks if the data matches the stored template. If there is a match, access is granted, and the door opens. If there’s no match, the door remains locked. This is a straightforward and efficient process.
The Matching Algorithm: Minutia Method
The most critical part of the fingerprint scanning process is the matching algorithm. This is often achieved through the minutia method. During the initial registration, several minutiae points are identified on the fingerprint pad, along with their positions and directions. This information is stored in the system's memory. During the matching process, the stored fingerprint template is compared to the new input. If there's a match, a green LED typically signals the approval, and the door opens. This process is incredibly quick and completed in a fraction of a second.
Each minutia consists of two instances of friction ridge skin impressions. These points are unique to each individual, making fingerprint door locks highly secure.
Professional Installation
Due to the sensitive nature of these locks, I would strongly suggest you contact the proper vendors and have them install the lock for you. Security is paramount, and professional installation can help ensure that the lock is set up correctly and securely.
Pre-Installation Checks and Visual Demonstrations
Before attempting to install a fingerprint door lock, make sure to read the directions on the package several times. A visual demonstration can be especially helpful, as they say, “A picture paints a thousand words.”
Check the manual that came with your lock, or search the internet for the specific brand and model you have. It’s also a good idea to ensure that the model is not easily hackable. If it is, you might want to consider a more secure option.
Setting Up Your Fingerprint Lock
The exact process of setting up a fingerprint door lock can vary depending on the model. Some locks work with a phone app, requiring you to configure both the lock and the app. However, many fingerprint locks are straightforward to set up. Simply placing your finger on the fingerprint reader is often enough to register it.
As an example, the SKLock fingerprint mortise lock is a good choice. It is priced at around $200, and the lock can open within just one second using a fingerprint. You can easily set and add up to 200 fingerprints to unlock your door. When purchasing a fingerprint door lock, make sure to choose one with a semiconductor fingerprint reader over an optical reader, as semiconductor readers are generally considered more secure.
