Putting Access Control Myths to Rest

 

Making the switch to EAC (electronic access control) from conventional solutions involving
physical keys and security guards can be a daunting process. With technology that is constantly
changing, making the move to embrace modern security solutions is a challenge for those who
have spent years with conventional products. While most decision makers may think that they
have a grasp on the pros and cons of going with one solution over another, it is important to
have an understanding of some of the misconceptions and myths that surround the field of EAC.
Here we will take a look at what some of these access control myths are and what the reality is in today’s security landscape.

 

#1. EAC Solutions are only for doors:

While it is true that these solutions were in their earliest iterations developed for door control
through hard-wired systems, the current technology extends across a wide array of standalone
products used in a variety of applications. Electronic padlocks and lockboxes are often
connected with EAC software and used to securer fences, sheds, garages and other outdoor
equipment, as well as indoor items such as cabinets, lockers and other interior storage.
Windows are commonly protected by EAC, and these solutions may also be used to tailor
access from person to person within an organization, splitting groups of people by access level.

 

#2: EAC Solutions are too expensive:

Although out-of-pocket costs are a given when replacing or implementing electronic security, the
benefits over the short to medium term are often enough to deliver a significant return on
investment, depending upon what issues the system was put in place to address. In some
cases, a strong EAC system can actually put money back into the businesses that use them by
eliminating labour and other overhead costs associated with the upkeep of antiquated systems.

 

#3: EAC Solutions are complicated:

Rather than create additional hurdles to jump for the enterprise security staff, modern-day EAC
technology is designed to address the pain points of traditional systems specifically to make
their use easier than the alternative. An organization making use of mechanical solutions would
have to deal with delays and downtime while trying to gain authorized access to restricted areas
or materials. But using EAC, employees can self-serve access to critical materials and sites
using mobile phones or access cards with complete assurance that only the right personnel are
gaining access to sensitive locations. Security managers will benefit from both flexible access
control and the enhanced monitoring made capable by a system that keeps constant and
accurate logs of all access and access attempts.

 

#4: EAC Solutions lack durability

While some may assume EAC products to be made from vacuum-formed plastics, the truth is
that they are generally made with the same quality or better of materials as their mechanical
counterparts are. The misconception that EAC products lack durability due to them containing
more technology is mostly baseless. Bluetooth enabled locks, for example, come to market
featuring wide metal bodies and boron alloys to resist cutting and sawing attacks just like
industry standard heavy duty mechanical locks. Many EAC solutions are weatherproofed to
prevent rusting and deterioration caused by harsh outdoor conditions. Also, the lack of a
keyhole helps prevent the effects of weathering by preventing moisture and particulates from
entering into the functional mechanism.

 

#5: EAC Systems are less secure

Bluetooth is one of the most popular short-range radio communications standards in use today.
When used in EAC applications, the user’s credentials remain protected behind the security
measures of their smartphone such as a PIN or biometrics. Within the last several years, 2FA or
two-factor authorization has been used to protect further from unauthorized access. With a
conventional keyed system of access control, the theft or loss of the keys would be a major
emergency and possibly require rekeying of multiple locks. Using EAC solutions, access is
controlled centrally and does not require any physical manipulation of a locking mechanism, so
a lost key card can simply have its access privileges removed. This is a major cost and time
saving measure over time and a big reason why huge segments of multiple industries are
switching to EAC.

 

The security of data in these solutions can be protected with 256-bit AES, end-to-end mil-spec
encryption to proof against hacking or tampering efforts. This is a standard that the NSA
maintains internally to be resistant to brute force attacks and is significantly more secure than
using just the standard security on a smartphone.

As you may be able to tell, EAC is becoming the de-facto standard for security. This market is
projected to continue to expand along the increased need for both physical and data security in
residential, commercial, industrial, and government facilities. Those who have not made this
transition away from lock and key security measures risk being vulnerable to increased
long-term costs as well as security breaches, particularly those occurring internally.
With reliability, scalability, and seamless integration into legacy security, EAC has shown over
the years to be worth the investment and even more than pay for itself in a wide array of
industries. Make today the day you make the move into the future of access control for your project.

The Future of Thermographic Cameras

As government and business leaders start to talk about “returning to normal,” and looking to thermal cameras to help, questions remain about how and whether the latest technology can help prevent the spread of COVID-19.

Across industries, everyone is looking for the right tools to help detect, slow and eventually stop SARS-CoV-2, the virus that causes COVID-19. By now we’ve all come to recognize that resuming operations in any way will require demonstrating measures to protect the health and wellbeing of people in a variety of situations, including travel and work.

One proposed solution is thermal scanners. Unlike most medical imaging approaches, infrared (IR) thermography doesn’t require irradiation or expensive equipment, and presents no health hazard. Infrared radiation emitted from our skin can be detected and used along with information about the ambient environment to estimate core body temperature — which may indicate someone is running a fever, a common early symptom of COVID-19.  While thermal cameras can’t detect a virus or a specific infection, they can help by quickly narrowing down a large pool of possibly infected individuals. And today, this represents the only viable non-contact mass screening approach for fever. The accuracy of the infrared system can, however, be affected by human, environmental and equipment variables. Understanding this multitude of variables — including the ways in which the science, technology and applications themselves interact — will help both users and system makers deliver the best results.

 

Consideration #1: Think about the method

Teledyne Thermometer-1

Thermal detection has been used for fever detection for 20 years now. While older thermometers and thermal cameras, including the type used to detect a different coronavirus, severe acute respiratory syndrome (SARS), had their weaknesses,  newer generations deliver significant performance improvements. More intelligent systems now offer features such as real-time calibration to ambient temperature with sub-degree °C accuracy, providing more accurate readings far more quickly than older generations.

Newer camera systems are also more user-friendly and more reliable, featuring automated target recognition, improved resolution, pairing with a visible-light camera, automated alarms for febrile cases, and clearer outlining of hot spots. This higher degree of granularity improves insight, allowing for a more efficient and faster screening process, and provides on-site health professionals with necessary information to take additional steps when required.

Consideration #2: Know your baselines

Because the environment can influence temperature measurements, some system makers have devised different ways to establish functional baselines. An early approach, recording a population baseline at each site on each day, proved too time- and resource-intensive. A newer approach, using a reference temperature source, or black body, offers evolutionary improvement. Designed to maintain itself at a specific temperature, the black body device allows the thermal camera system to automatically calibrate. Even better is a radiometric camera, which can interpret the intensity of an infrared signal reaching the camera. This requires more rigorous design and testing by the manufacturer, but it delivers much more precise measurements.

Consideration #3: Looking in the right place

While thermal cameras can only detect surface temperatures, different parts of the human body more closely correlate with body temperature. Based on recent scientific research, the most reliable spot in the human face is the canthus, the small corners over the tear duct of your eye where the upper and lower eyelids meet. This kind of precise targeting requires accurate pixel calibration capabilities.

Consideration #4: Checking your performance         

Operating an IR fever screening system in the lab is one thing, but out in the field, the situation becomes more complex. Users need a camera system that is reliable and stable when it comes to critical performance factors like resolution, sensitivity and frame rate. Understanding the performance considerations when imaging a subject at a distance, for example, and realizing the minimum number of pixels required to get an accurate measurement are both essential in staging a fully optimal fever-detection platform.

 

Consideration #5: Finding your way in the “wild west” of thermal imaging in early 2020

People from the many industries that have been devastated by this pandemic – including travel, sports, manufacturing, food and hospitality, and entertainment — are looking for ways to reopen businesses safely while reducing the probability of a second wave of COVID-19. Deploying technology such as IR fever screening systems as part of a range of preventative measures will hopefully support that effort.

As is the case with any promising emergent technology, there is a fair degree of chaos around the nuanced considerations of system design and performance. What standards apply to IR fever-screening devices? Which are being enforced? Who makes them? Will they work? These questions will only be answered with time, and in the meanwhile your best bet is to go with a company that has the experience and expertise to properly implement these solutions for you.

The Future of Epidemiologically Driven Access Control Post-COVID 


Business and organizations across the world are dealing with the dire economic and personal impacts of COVID-19. Confidence is now a major issue in helping people return to work and restart their normal activities, whether that’s sending children back to school or visiting shops.

Organizations looking to safeguard against COVID-19 can now bring back the confidence by choosing from newly developed solution ecosystems designed to create safe and healthy environments.

Access control measures designed to target those who are symptomatic are just one piece, and technologies to measure and enforce social distancing and mask compliance are also available. 

Following are some solutions to a multifaceted COVID response.

  • Machine Learning Kiosks are the right choice for venues wanting to ensure social distancing in their building and the use of face masks at all times.

  • Temperature Screening: Perfect for organizations looking for the ability to scan a person’s temperature and create standard procedures to help operators consistently manage results.

  • Control Center Temperature Screening: Ideal for organizations with video management software and that need to implement an integrated thermal screening solution.

  • Thermal Camera Temperature Screening: Designed for organizations looking to add a standalone temperature screening thermal camera to their existing network.

 

 

Ensure social distancing 
 

Following government guidelines and maintaining appropriate social distancing is essential in combating COVID-19. Kiosk AI helps you create healthy environments for visitors by using people counting technology, combined with artificial intelligence, to track entrances and exits from your establishment to ensure you are always at optimum levels for social distancing.

As this solution is an automated system you won’t need to scale up your overheads during these challenging times. At the entrance to your business a screen will display the number of people in your venue, plus maximum capacity, and inform visitors if they are free to enter.

 Ensure the use of face masks to create safe environments 

Encouraging people to restart their regular activities is all about giving them the confidence in their surroundings and the proper use of face masks has been proven as an effective method for limiting infection rates. AI Kiosks deliver this valuable layer of protection by monitoring people entering your venue and detecting the ones not wearing a face mask. Visitors not wearing a mask are automatically advised to wear one before proceeding, with alarms enabling you to respond immediately to non-compliance.

Procedures for high temperature screenings 
 

Temperature screening begins by delivering a safe and contactless screening of a person’s temperature using a thermal camera and a heat emitter device, known as a Blackbody, that is used by the camera as a reference point.

If the person is below the defined level, for example 35°C, then no action is required and the person can pass swiftly into the building. However, if the threshold temperature is exceeded then an on-screen alert appears and the high temperature procedures are activated. These will guide the operator in delivering the correct response to the results and ensure a consistent approach that helps avoid human error.

Create custom procedures for different categories of people 
 

Temperature screening measures provide a tailored and adaptable solution for helping organizations manage temperature screening results. Custom operating procedures can be created to guide operators in how they deal with different categories of people, whether they are employees, visitors, customers or contractors. Procedures can also be instantly changed to keep pace with changing requirements.

By implementing these custom procedures organizations can provide:

  • Peace of mind for employees and visitors beyond checkpoints

  • A duty of care by alerting and helping employees and visitors manage screening results

  • The processes to manage the threat of COVID-19 within their workplace

Security Technology of South Texas offers a full suite of access control measures to fight against the spectre of COVID. Whether you need to implement just thermal cameras or a complex integration of multiple solutions, we can set your business up to be safe and compliant.

InVid Body Temperature System

 

InVid Tech has released a Dual Spectrum Camera System to measure the temperature of objects, humans, or animals. While alternative solutions do exist for ensuring the basic health of people coming and going from a location, this system can automatically and accurately read the temperature of multiple people at the same time every second and has an accuracy of + or -0.54 Degrees F. This is a viable solution in high traffic areas and where it would be unreasonable to place a person to do manual contactless temperature readings.

When an individual with a temperature above the set threshold comes through, the system alerts. Unlike cheaper imitation products on the market, this high-end system is complete and requires no other systems or human intervention to work. Included in the product is an always-on calibration device to make sure readings remain accurate. This device is critical in making accurate readings from a distance and for capturing the temperature of multiple people.

 

By combining facial recognition technology into this system, the camera differentiates human faces from other information in the frame. This triggers it to scan for a temperature reading, which if elevated, will in turn trigger an alert. The system consists of the camera itself, the CMS software to which recordings and alerts are sent, and a black body object which is used to calibrate for temperature.

 

Features of this system include:

  • On-board temp-detection algorithm
  • One IP address two channels
  • Standard Image: 2 Megapixel (1920 x 1080) Resolution
    Thermal Image: Effective pixels 400×300
  • Sensitivity 40mK
  • Thermal: 8mm Fixed lens, Visible: 2.7-12mm motorized lens
  • Accuracy within 0.54°F  (0.3°C)
  • Body detection, up to 16 Targets
  • Response Time 30ms
  • 17 color control

 

With the world seemingly changed by COVID-19, these systems will only continue to increase in demand.  Many businesses wish to protect themselves from liability, and a system that can pick the sick person out of a long line of people passing through a checkpoint is an efficient and cost-effective way to do that.
