Vital signs are measurements of the body’s most basic functions. The following main parameters are normally monitored by medical professionals to identify the illness:

  • Body temperature
  • Pulse rate
  • Respiration rate (rate of breathing)
  • Blood pressure (Blood pressure is not considered a vital sign, but is often measured along with the vital signs)

Vital signs are useful in detecting or monitoring medical problems. Vital signs you may have already noticed, when you get sick, your resting heart rate tends to increase and your heart rate variability tends to decrease.

While you might see these changes during the early stages of an infection, we often don’t experience obvious symptoms. The immune system and the central nervous system work together in complex ways to target a foreign virus even before we’re aware that we are sick.

When infections become severe enough, one coordinated attack these two systems produce is the febrile response, commonly known as a fever. When the immune system detects a foreign pathogen such as a virus or bacteria, it sends a signal to the brain to increase the body’s core temperature, causing the sympathetic nervous system to respond by producing more heat. When the temperature rose by 1 degree C, the heart rate increased on the average by 8.5 beats per minute.

By creating a personal baseline while you are healthy, vital signs daily measurement can be used to identify signs of illness sometimes before you actually feel sick and potentially before a doctor – without recent data of what your personal “normal” looks like – would recognize that something was wrong.

Vital signs monitoring (Body temperature, Pulse rate and Respiration rate) daily measurement can serve as an early detection system and useful in detecting medical problems, such as those demonstrated in persons infected and fighting COVID-19.

Being included in access control procedures, vital signs screening can be effectively used to provide facility-based surveillance for healthcare-associated infections, including infections in healthcare workers and inpatients, which is one of core components of COVID-19 infection prevention and control.


MOD-601 Remote sensing solution enables the most accurate and fastest VSAC screening and is mainly used at board control gates, health facilities, offices and government buildings, marketplaces, schools and industrial facilities.

The system consists of two dynamic real-time screening cameras installed on special stand with cameras tray and computer. The first camera is fitted with a thermal sensor, an RGB sensor and two 3D sensors for infrared thermal imaging. The second camera is fitted with laser sensor for measurement of Pulse rate and Respiration rate with medical grade accuracy.

Vital signs monitoring (Body temperature, Pulse rate and Respiration rate) is mainly used at control gates or where crowd screening is not possible.
