According to the CDC, contact tracing is key to slowing the spread of COVID-19. It helps keep you, your family, and your community safe. In general, contact tracing involves identifying people who have a contagious disease (cases) and people who they encountered (contacts) and working with them to interrupt disease spread. This includes asking people with COVID-19 to isolate and their contacts to quarantine at home voluntarily.
This article reviews the best ways to provide contact tracing.
The latest access control
systems are much easier to install than the older systems. Of course, it’s
only easy if you know exactly how to connect everything. The devil is in the
details, and this article provides the wiring diagrams you need to make your
access control system work.
As a review, the advantage of IP access control systems is
that everything is located at the door. The following diagram shows an example
of an IP access control system that uses a reader-controller.
So far, this year has been quite tumultuous.
It is the year of the great pandemic and the year of social change. The
turbulence of our time has created demands on technology. The use of face recognition
provides touchless access control, and temperature scanning with face mask
detection helps to limit the spread of disease.
The latest IP cameras include artificial intelligence and can
detect people who are too close together. Automated contact tracking has been
introduced to help reduce the spread of disease.
The article discusses some of the new technology that can help
in these difficult times.
The pandemic of 2020 has caused all of
us to think differently. More than ever, we are concerned about the spread of
disease. Some people believe that this concern will last well beyond today’s
pandemic. Just like the changes that occurred after 9-11, the world will be
different in the future.
One way to control the spread of
disease is to reduce the amount of surface contact. Biometric systems that use
fingerprints, palm recognition, or finger-vein are being replaced by face
recognition. This has the advantage of providing contactless or touchless door
entry control. This article reviews several new products that use face
recognition to control door entry.
The Pros and Cons of Thermal Cameras That Measure a Person’s Temperature
Thermal imaging cameras have been around for many years. They
were first used in the 1940s and 1950s by the military. Long-range camera systems use
thermal cameras to help with detection, recognition, and identification (DRI)
of targets. They have also been used in previous pandemics.
Today, thermal imaging cameras have
become popular because of the outbreak of COVID-19.
Some of the older thermal cameras
have been repurposed to measure a person’s temperature from a distance. The
latest systems are designed for measuring people’s body temperature and have
been integrated with door access control.
This article reviews the various technologies and how they can help monitor people as they enter a secure area.
If we want to detect an object that is miles away, is the magnification
of the lens the most important, or is it the camera resolution? It turns out
that many factors determine the effectiveness of a long-range
The things that determine the performance of a long-range
camera system include the magnification provided by the lens, motion of the
object, camera resolution, atmospheric clarity, lighting, and contrast. All these variables are inter-related.
This article discusses all the factors that determine how successful you will be in detecting an object (target) that is very far away.
How IP Camera Systems and Door Access Help With Infectious Disease Control
The current health crisis has placed a significant strain on all hospital resources. Besides the problem of medical supplies and protective equipment, they have been struggling with finding rooms for all the new infectious patients. The hospitals have been creating inventive solutions to meet these challenges.
IP surveillance, intercoms, and door access control have
been used to control how people move through all areas of hospitals. This
article describes how technology is being used to help hospitals and other
healthcare organizations meet the challenges of the COVID-19 pandemic.
