One returns home in a joyous mood after having a happy weekend outing with the family. However, all the joy vanishes in the thin air when one realizes that the bunch of the house keys has gone missing in the outing revelry. Alternatively, the lock on the main entry has been bumped by the thieves who made it good with all the valuables of the house. If you do not want to face this trauma, then it is time you secured your home and office with hi-tech digital door locks.
Digital door locks rid you of the burden of carrying a heavy bunch of keys and make your home highly secure against thefts. To open a digital door lock you simply need to press a secret code made of numbers or letters or both on the locks’ keypad. The unique combination that opens these locks can be changed by applying a mechanical procedure that is described in the user’s manual. A lock cannot have two combinations.
Though the keyless use is a highly advantageous feature of digital door locks, keys are also provided to open them. Many advanced versions of digital door locks even use radio-frequency identification (RFID) tags to identify the residents of the house. On these tags are stored the biometric details, like fingerprints, retinal or iris scanning and voiceprints, of the residents. Therefore, these can only be opened by the real residents of the house. An RFID tag that opens a digita
l lock can even be kept in one’s mobile.
No wires or external power is required for many home digital door locks as they run on long-life batteries. Others, actually do require power to be wired to the door. But, the powered digital locks are generally for a higher level of security and are part of an integrated security system in many cases. Whether directly powered or running on batteries, most of these locks, made of high-quality stainless steel or brass, are weather-proof. These locks come in push-button, knob and lever handle varieties and can be opened from inside or outside. Some locks automatically lock a door when it is closed.
While biometric door locks are certainly becoming more popular, the more basic RFID digital door lock that operates using a key card is still far more common. This type of lock uses a sensor in the door lock to detect a “key”, which is just a chip that is embedded in a card that the homeowner carries in their wallet or purse. When the card is brought in close proximity to the door, the digital lock open automatically. This is very convenient for most people as it means you just need to get your wallet or purse near the door and the door unlocks for you. Each of these types of locks has a unique code that works between the key card and the door lock, but multiple locks in a single home can be keyed for the same key card.
There are obviously many choices in digital door locks for your home. And while still relatively expensive, the costs are coming down qickly as the technology becomes more widspread. The RFID digital door lock with a key card offers good value and extreme ease of use that is simlar to the familiar concept of traditional locks and keys. The biometric locks offer a higher degree of security and are more expensive, but if you need this level of security in your home, the technology is finally far enough along that you can get a very good biometric system installed in your home by a local contractor.
