Over the years, the data breach has become a significant concern for businesses around the world. To reduce their risk of data breaches, businesses need to review and take steps to improve the security of their facilities. One way to do this is by restricting access to important areas. An unauthorized person gaining access to sensitive areas is a recipe for disaster. Businesses around the world recognize this and use door entry systems to improve the security of their facilities.


Door entry systems: An introduction

The door entry system is a critical component of a property’s premises security infrastructure. A conventional residential door entry system includes a doorbell and an intercom. When a person requests access to the property, the occupant can use the system’s doorbell and intercom to communicate with the visitor and decide whether the person should be granted access.

Some of the most common types of residential door entry systems include audio buzzer systems and video door entry systems. Lately, many homeowners have started using mobile phone and internet door access systems that can be controlled from any part of the world.


Different types of door entry systems used by businesses

Many businesses need advanced solutions to safeguard their facilities. These solutions require the person requesting access to pass multiple levels of authentication. Some popular commercial door entry systems used by businesses are


Stand-alone locks

Stand-alone locks are usually used to secure a single access point. Powered by replaceable batteries, stand-alone locks can be unlocked using a keypad, a card, or both. One of the many benefits of stand-alone locks is that they are ready to use within minutes after installation. Many models come with a handheld reader that can be used to extract audit trail.

Proximity readers

Proximity readers are the most common type of commercial door entry systems used by businesses. These systems require a person requesting access to a particular area to swipe their card or badge on a reader installed at the access point. Proximity readers are easy to maintain. If a user misplaces their card, a new card can be easily issued, and the old card can be deactivated. Proximity readers also allow the admin to include additional verification methods such as the use of photo IDs.

Modern proximity cards are designed to be scanned when placed at a distance from the reader, which means users no longer have to swipe their cards to get access. One of the reasons why businesses use proximity readers is their affordability.

Biometric door access control systems

Biometric door access control systems offer the highest level of access security. These access control systems use physical characteristics such as retinal scans, fingerprints, or handprints of people requesting access to identify them. Readers are installed outside access points to scan fingerprints, handprints or patterns on a person’s retina blood vessels. Once the scan is obtained, the system matches it with its database to determine whether the person should be granted access.

Though biometric door access control systems offer a higher level of security, their large scale use is still a few years away as these systems are more expensive than other options and are often considered invasive by people who are required to use them on a daily basis.


Tips to improve your door entry system


To ensure the system serves its purpose, you need to have an improvement plan that focuses on identifying and addressing system weaknesses at regular intervals in place. To help you get the most out of your door entry system, we have compiled a list of few door entry systems tips. Take a look.


1. Review who has access periodically

Oftentimes facilities managers forget to deactivate a card after an employee is terminated or resigns. A disgruntled ex-employee with a functional access card can do more damage than you could imagine. To avoid security concerns, audit the system regularly to review who has access. Your facilities managers can also set features to timeout access cards after a certain period of inactivity.

Assign cards with contractor written in the name field to third party and vendor employees. Deactivate these cards every 3-4 months. Have a system that allows them to get the cards re-enabled, in case they still need access after the period in place. For visitors, use cards with visitor written in the name field. These cards should expire at the end of the day.

2. Keep up to date with technology

If you’re using 125-kilohertz technology, its time to upgrade. 125 kHz technology has several loopholes that allow cards to be replicated easily. To address this problem, security experts recommend installing encryption technology. Install software updates as and when they’re available.

3. Test your system regularly

Test your system’s efficacy at regular intervals. Try using a deactivated card to gain access to restricted areas. In case the system issues an alarm, you don’t have anything to worry about, however, if the system grants access, call your vendor’s support team immediately and get the issue fixed.

4. Watch out for tailgating

Train your employees never to hold the door open for anyone. Educate your security staff on the risks of tailgating and instruct them to stop any employee from using their cards to get another person inside. To deal with tailgating, use multiple layers of security.

5. Determine access levels

Not all your employees need access to all the areas in your building. Your facilities manager and supervisors must decide the right level of access for different parts of your building. Every supervisor must sign an access form that details the levels and areas of access, and times and days, their team members were in the building. Connect the system to a human resource database that is designed to revoke access once an employee quits or is terminated.
