When it comes to security, the investment is always worth it. And technology has evolved to help in this regard as well. So much so that, today, the biometric lock, which was previously inaccessible, is increasingly present in homes and offices.
In this Buying Guide we will explain everything about the electronic lock with biometric access.
What is the biometric lock and how does it work?
The biometric lock is an electronic lock whose mode of access, to open and close the door, is made through the reading of the fingerprint.
Because it is an electronic lock, biometric does not use keys. However, as we will see later in this article, it is possible that the biometric lock also has other forms of access, in addition to digital printing.
This type of lock can be installed at your home, at a private event, at your company, among other locations. For the person to have access, just register the fingerprint in the lock.
t works like this: The biometric lock has a reader that will register the fingerprint of the people authorized to enter the place. So, when they put their finger on the reader, the door will be unlocked.
With this operating system, the biometric lock is one of the most secure, since the fingerprint is a unique feature of each person.
With that, the chances of invasion are infinitely less if we consider other types of electronic locks.
What is the difference between the biometric lock and other types?
The biometric lock is just one of the types of electronic locks. What differentiates them is, in fact, the operating system that can be through card, key chain, password, apps and biometric.
And although the most modern lock models may contain all or almost all of these methods of opening and closing the door, this is not a rule.
What is common to all electronic lock systems is the fact that keys are not required to open and close the door. But depending on how you can access the site, there are pros and cons.
Therefore, it is important to know the characteristics of each type of electronic lock. For that, check out the table we prepared for you:
Can I install the biometric lock on any door?
No. To install the biometric lock, you must first follow the manufacturer’s recommendations. That’s because, each electronic lock is manufactured specifically to be installed in a type of door.
In general, when choosing the best biometric lock, it is essential that you check the installation method, thickness and material of the door.
Regarding the way to install the biometric lock, there are two models: recessed and overlapping.
The overlapping biometric lock can be installed without removing the original lock. However, it should only be placed on doors that are 25 to 50 mm thick.
The built-in lock is installed inside the door. Therefore, this biometric lock must be placed on doors with thicknesses above 35mm.
Another point that deserves your attention is that, if your plan is to install the biometric lock on a glass door, you must choose a specific model for that type of door and respect the minimum thickness of 10mm.
What are the pros and cons of the biometric lock?
The great advantage of the biometric lock is, in fact, the high level of security it provides and the absence of keys.
With this type of lock, you control who enters and exits, whether from your home or office.
Another advantage is that, due to the efficiency of this type of lock, it is not possible to circumvent the system, as can happen, for example, with the electronic password lock.
In summary we can say that the main positive points of a lock with fingerprint reading system are:
- High security ;
- Greater access control ;
- There is no need to use keys ;
- There is no need to remember passwords ;
But, considering the variety of existing models, we can say that the advantages of having a biometric lock go even further.
The non-transferable and non-copyable access is one of the positive points of the biometric lock.
After all, if we consider a traditional lock, we know that the keys can be copied and the door itself can be broken and damaged in this attempt.
In addition, the lock with biometric access, in general, also has other ways to open and close the door. Not to mention that there is always the possibility of using a physical emergency key.
Due to the high technology involved in the manufacture of biometric locks, the most advanced models have several other features that help to reinforce security and prevent invasions.
But the biometric lock has more than just advantages. Because it provides a high degree of security, this type of lock is often quite expensive.
In addition, as it is an electronic device, it is subject to defects. For you to have a broader view of the positives and negatives of a biometric lock, we have created the following table. Check out:
How much does the biometric lock cost and where to buy?
With a simple search on the internet, you will find biometric locks that can cost up to R $ 4 thousand. But you don’t need to invest the most expensive model.
It is possible to find options for sale for around R $ 500. But, to avoid buying a low quality biometric lock, we recommend that you look for one with an intermediate price.
You can buy this type of lock in specialized stores, department stores, such as Casas Bahia, and even in supermarkets, such as Extra.
But if you want to save and buy without leaving home, it is worth giving a chance to online stores like Amazon Brazil. Not to mention that there you will find a greater variety of brands and models of biometric locks to choose from.
Purchasing Criteria: How to analyze biometric locks
When it comes to action and buying the biometric lock it is important to know how to differentiate one model from another.
To do this, you need to understand a little about the technical settings of the device. The first of these, as we have already seen, is the form of installation that must be in accordance with the type of door. Check out others:
- Number of accesses
- Other types of access
- Extra features
- Design and doorknob
Below we will explain each of these topics.
Number of accesses
One of the questions you should consider when buying a biometric lock is the number of accesses that the device allows.
The biometric lock can allow access for 20 to 100 people.
In general, the biometric lock can allow 20 to 100 people to access the site through fingerprint.
Still, it is possible to find some models that even allow the registration of up to 500 fingerprints.
Other types of access
There are models of locks that allow access in up to three other different ways, in addition to biometrics such as digital password, tag and key.
Choose the one that will be most useful according to the number and profile of users who need access to open and close the door.
Did you know that biometric security methods consist of personal identification through some physical characteristic?
The identification can be done through the fingerprint of the finger or hand, iris, voice, among others.
In addition to opening and closing the door by reading the fingerprint, the biometric lock can also have other functionality.
In general, these functions help to reinforce the security and privacy of the place. The features vary a lot depending on the model and brand of the biometric lock, but we have selected the most common ones. Check out:
- Audible alarm: This function is activated in case of any attempt to break in the door;
- Self-locking sensor : This sensor locks the door even if you forget to do so;
- Smoke or heat sensor: This feature of the biometric lock causes the door to open automatically in case of fire;
- Do not disturb function : With this function present in the biometric lock, anyone, even if registered, is prevented from opening the door;
- Voice command: Some biometric locks allow you to use your voice to change settings and access;
- Battery signaling: Alert when the electronic lock battery is running low.
Design and doorknob
Be sure to also consider the design of the biometric lock. In general, these devices are very modern and can present the fingerprint reader in an exposed way or hidden by a kind of door.
In addition, the design also varies according to the presence or not of the handle. In this regard, take into account the practicality, the style and also the way of installing the biometric lock.
