We all know that access control is first priority when it comes to safety and security for any location. The potential for theft, damage, or other issues is mitigated when entry is tightly controlled. The best news is that there is an entire world of options when it comes to door entry access control.
One of the best options is the most modern: proximity door entry access control.
This form of access control relies on electronic sensors to read the credentials of anyone wishing to gain access. Credentials were traditionally a key, a code, or another tangible object that a person possesses. However with proximity sensors, the credential options have expanded.
Proximity sensors can scan for the presence of an access card that the user keeps on his or her body. They can also scan for physical attributes, such as facial features, in more advanced applications. In low security situations, proximity sensors can operate access control by scanning for movement.
The simplest form, scanning for movement, is one recognizable to anyone who has visited a grocery store in recent years. The door swings open once a person has crossed a certain threshold, making for easy access especially when hands are full.
For security purposes, the core of access control, proximity sensors will need to detect a credential for entry. This usually takes the form of an access or ID card that individuals carry on their person. This is a relatively high security format that allows only those with official credentials to enter.
There are risks, of course. The cards can be lost or stolen, and sophisticated hackers have found ways of lifting information from them. But as a fundamental form of access control, proximity sensing is one of the best available.
