If you have a location that you need secured, using a fingerprint door lock is not a bad way to restrict entrance. A biometric door lock alone does not represent a full security solution, but it’s an easy way to prevent people from casually or accidentally entering a place you don’t want them to go. It may be difficult to find a store that sells biometric door locks since they’re not the sort of thing folks drop by the local hardware store to pick up.
You will probably end up comparison shopping on the Internet for your lock, but finding a dedicated security store or talking with someone from a security firm is a good idea. If you’re serious enough to buy a fingerprint door lock, you’re probably serious enough to need the advice of a professional. The least expensive door lock of this kind will run you about $100. Such low end locks will not read fingerprints all that well though, and that makes them more susceptible to being cracked. If someone can somehow get a copy of an authorized print, whether from a coffee cup or a glass object or some other similarly smooth surface, then your security level just dropped dramatically. Mid-range locks from companies like Biolock and Barska are more effective in that regard, as they have better scanners and can hold more fingerprints in their databases. High end locks like the BioKnob can store as many as 100 prints, and that makes them ideal for higher traffic areas that still require biometric security. The storage capacity is something easy to overlook, but it’s critical to know for planning purposes. Once you have picked out a lock, you will want to do some testing on it to determine just how rigorous the scanner is. Independent firms have found that some biometric security locks can be fooled by something as simple as a high quality photocopy of an authorized fingerprint. If you find that to be the case with your lock, you will probably want to choose a different one.
For more sophisticated attacks, you may need to contact a security professional with a specialization in biometric locks. One of those people will be current on all the different ways the people try to break into them. Finally, you will need to make sure that you have a maintenance procedure in place. Many fingerprint door locks will beep or otherwise give off an indication when the battery is low, but someone still needs to have the responsibility of changing that battery. The fail safe for most locks is simply for them to be operable by a key, but if you wanted key entry, you wouldn’t be looking into a biometric security system. Proper maintenance on these devices is also critical since a lot of the more affordable locks only have warranties of about a yearlong. As a part of an overall security plan, a biometric door lock can be an easy and convenient way to restrict access to an area that needs more protection than a simple key or combination can offer. If you are careful in selecting your biometric security system, you should have no problems keeping out whoever it is you need kept out.
