Frequently Asked Questions
Given below are answers to the most frequently asked questions regarding smart locks. You might be able to have a better understanding of smart locks once you go through these questions.
How do Smart Locks Work?
Most smart locks are connected to the Internet through your Wi-Fi system. This allows the lock to be connected to your smartphone to allow identification. Connectivity to the Internet also will enable locks to store various access codes. If your smart lock is not Internet-powered, it can scan a fingerprint or allow passcode entry, which acts as a non-physical key.
Are Smart Locks Safer than Regular Locks?
Yes, smart locks are more secure than regular locks. Not only can no layman duplicate the passcodes that can be used to unlock smart locks, but the log data allows the user to see if some unusual activity has taken place. Smart locks are safer because they include anti-burglar alarms that will warn the user if someone is trying to enter their property by force.
Can Smart Locks Be Hacked?
Yes, smart locks can be hacked. However, if you buy a lock from a reliable company, you will receive a so well encrypted lock that only expert hackers will be able to get past it. If you want to negate the possibility of hacking, you can remove the Wi-Fi connectivity from the smart lock. This will make it go off the radar but still be unlocked with a fingerprint, passcode, or id card.
Do Smart Locks Require Electrical Connections?
No, smart locks are standalone units. They work with the help of batteries that are put into them. These batteries generally need to be changed on an annual basis. Smart locks’ wireless existence makes it easy to be installed and allows them to work even if your house has a power cut. In case your battery drains, some locks can be connected to wires, though.
Is it Safe to Assign Custom Codes to My Friends?
If you trust your friends, yes. However, instead of times codes, if your lock supports eKeys, they are better. This is because eKeys can only be used once. Therefore, you do not risk them sharing the passcode with someone else, or you forget to manually delete the passcode information.
Smart locks are the future of home security systems. Adding smart locks allow you to go about key-free, and most of them have extra security features that come in handy in tricky situations.
There is a huge variety of smart locks to choose from to ensure your house’s safety. You must always choose locks from reliable companies for optimum safety and use the safety features mindfully.
