1. Safety: After installing the fingerprint lock, it should not affect the function of the anti-theft door. There should be no obvious security risks associated with the lock.
2. Stability: This is the most important indicator for fingerprint locks. It usually takes over a year of actual use before it stabilizes and becomes set. When choosing, consumers should opt for manufacturers that primarily produce fingerprint locks. These companies generally have better production experience. Research and development experience is the best stabilizing factor.
3. Universality Monitoring Camera: It should apply to most domestic anti-theft doors (in compliance with the 2008 version of the national standard for anti-theft doors), requiring minimal modifications. The installation time for a good fingerprint lock should not exceed 30 minutes. Otherwise, users may find it difficult to complete the installation and maintenance themselves. Good universal design can also effectively reduce dealer inventory.
4. Intelligence: Operations such as adding or deleting should be very simple, without requiring users to remember too many commands and codes. High-performance fingerprint locks are equipped with video display systems, making user operations more convenient.
5. Manufacturer Brand: If you ask me which brand of fingerprint lock to choose, I can only say to choose the one with the best customer service. This is the key to selecting a fingerprint lock. Only when the manufacturer's production quality is guaranteed can users feel at ease; only when the manufacturer's after-sales service is guaranteed can problems be solved in a timely manner (no product is indestructible, don't assume your purchase will never break); only when both quality and after-sales service are guaranteed can users avoid being locked out.
6. Function: Choosing the functions of a lock involves meeting personal needs while also considering the quality of the lock. A good company often has at least five different levels of fingerprint locks for users to choose from. Users typically select products based on their usage: there are those for entrance doors, divided into metal and wooden doors, and those for indoor room doors, commonly wooden, and also used for villa main doors made of wood, etc. The basic functions usually include:
1) Multiple people can open the door via fingerprint (a household or office often has more than one or two people), ensuring stable product quality and good performance;
2) Different permissions for opening the door (it's impossible for the homeowner and the maid or cleaning tools to have the same door management permissions);
3) Ability to freely add or remove fingerprints for opening the door (when a maid leaves, her fingerprint can be easily removed);
4) Best to have a query record function (you can check the door opening records anytime, sometimes becoming critical evidence, generally requires a display screen);
5) Appropriately includes some password function (since the fingerprint part is electronic and may malfunction, the homeowner can temporarily use a password to open the door), but when choosing, try not to select products that overly emphasize the password function, as passwords are not as secure as fingerprints. Usually, there are 4-key and 12-key options. In daily life, try not to use the password to open the door, which can effectively prevent theft;
6) Must have a mechanical key, this is a backup way to open the door. Just like planes and cars, although they have automatic control states, they still retain manual control parts, which is a safety consideration. Any electronic part has the possibility of error, relatively speaking, the mechanical part is much more stable. Keeping the mechanical key of the lock as a backup way to open the door at home can solve problems promptly and facilitate repairs when the electronic part of the lock malfunctions. Imagine if a fire breaks out at home, or if a thief damages the electronic part of your door because they couldn't break the lock, what would you do? Don't blindly pursue so-called psychological safety and ignore the fallback option by choosing a lock without a mechanical key. Actually, using a fingerprint lock is mainly about enjoying its convenience rather than improving security. To enhance the security of the fingerprint lock, it can be connected to a smart home system. Currently, some fingerprint lock manufacturers reserve development ports for fingerprint locks. In smart homes, simply developing the fingerprint lock can allow real-time monitoring of its status, thereby enhancing the security of the fingerprint lock.
7) Choose a good lock core. The quality of the mechanical key lock core directly affects the anti-pry ability and stability of your door. This part is also very important. No matter how good the fingerprint lock is, it ultimately cannot do without the lock core part. Generally, powerful fingerprint lock manufacturers will choose high-end lock cores, thus ensuring product quality. The most obvious thing consumers can check is the number of pins and depth levels on the key. Try to select products with more pin numbers and depth levels. The exponent of the depth level pin number is the key quantity of this mechanical key, the larger the key quantity, the better the security. The national standard generally requires at least Grade A locks, and good fingerprint lock manufacturers usually configure super Grade B mechanical keys.
8) It's best not to choose other flashy functions. Basically, they are not practical. More functions mean more possibilities of malfunctioning, and once the product malfunctions, you need to decide whether to repair it or not. If you repair it, the maintenance personnel will charge you for the service (home visits are not free).
7. Style: The choice of lock style varies from person to person, so it's hard to draw conclusions. In general, look at the material, shape, and color. Currently, the materials of lock bodies on the market are mostly stainless steel and zinc alloy, with some aluminum alloy and plastic ones as well. For entrance doors, you must choose stainless steel or zinc alloy ones. For bedroom and other indoor doors, it doesn’t matter. Surface treatment methods are also crucial. Some products look luxurious and beautiful (especially online pictures that are design renderings or processed photos), but after users buy them home and use them for a period, they will find fading signs on the handles or other frequently touched areas. Such products actually use spray paint instead of electroplating during surface treatment, which is a deception to customers. Therefore, consumers must clarify these details before purchasing and agree with the manufacturer in advance on how to solve such problems. Otherwise, spending thousands of yuan on a fingerprint lock that fades within a year will make it a waste.
8. Price: Prices on the market vary greatly, ranging from 1500-4000 yuan for ordinary fingerprint locks, and higher for villa types. In general, consumers need to compare the cost-effectiveness of products based on their needs and purchasing power. The general principle is that you get what you pay for. Especially for friends who want to enter this industry as dealers, they need to carefully compare and preferably visit the other party's enterprise for an inspection. The above experience organizes documents from previous people and presents fingerprint locks clearly to readers, hoping to be helpful! Thank you for reading!
9. Manufacturing Materials: As the saying goes, you get what you pay for. When choosing, look at the product materials. Mainstream materials are mainly zinc alloys, with some using iron sheets, and some manufacturers extensively use plastic materials for appearance. The lock body of key components is currently made of cast iron by most manufacturers, with some using stainless steel. When selecting, users should also look at specific materials. Different materials have different safety and durability. Surface treatments are divided into electroplating and baking paint. The latter looks good initially but wears easily. The former is very durable but has a high scrap rate and manufacturing cost. Camera Attendance Machine
