Using A Biometric Door LockThere are a lot of advantages to having a biometric door lock. You never need to worry about carrying a key, as all you need to get in the door is your fingerprint. You can program in a large number of fingerprints of people allowed to open the door, and you don't have to worry about people forgetting or losing their keys. There are a bunch of different manufacturers of biometric door locks, so if you are interested in purchasing one of these you shouldn't have a problem finding a supplier. When you are purchasing a biometric door lock there are a number of things you should look into. You want to check out the number of different users whose fingerprints you can program in to make sure there are enough for your purposes. Many biometric door locks also have a key override in case there is a problem with the system. Most of these use regular, duplicable keys. It is common for these types of doors to operate on batteries, so look for one that gives you a warning when the power is getting low and that will still retain the biometric data even if power is lost so that you don't have to scan everyone's fingerprints again. Most of these batteries will last for about a year before needing to be changed. In order to save on batteries, most biometric door locks are normally on standby and need to be woken up, so you should check to see how this works. Some use motion detectors, others have slides covers or other methods of waking the lock up for use. For outdoor biometric door locks, you want to be sure to get a lock that is weatherproof and has a dust cover so that the elements won't damage your lock. You also need to check what is needed to enroll new biometric data into the lock, and how the users are deleted. Many locks use pin codes to determine who can add new users, and allow you to delete users individually. Other features you might want to check out include the type of sensor, the type of latch, whether or not the lock has a deadbolt, if there is an LCD display, whether the handle is reversible, if there is a standby power pole, a security threshold, and an audit trail. The audit trail might be useful for those who are particularly security conscious because you would be able to see who came in and when. |
