Did you know that body temperature checks can be done through CCTV? Check out the following information!


Did you know that CCTV already has body temperature checking technology? Yes, body temperature checking technology or thermal check-up can already be adapted by CCTV monitoring cameras to make it easier to check body temperature during a pandemic.

The Covid-19 handling task force urges business actors to prepare a body temperature checking device or thermal camera at their place of business so that they can monitor incoming visitors.

The importance of checking body temperature is one of the efforts to find out whether the person is infected with Covid-19, one of which is an increased body temperature.

Normal human temperature ranges from 36.5 degrees to 37.5 degrees Celsius. Therefore, if the detected temperature is more than 37.5 degrees, there is an indication that the person is sick or infected with the Covid-19 virus.

Now in this article, we will discuss further about whether there is a CCTV camera that can directly check body temperature. Of course this will simplify and speed up the process of checking body temperature for visitors who come to malls or other tourist attractions.

Overview of CCTV

We must be familiar with CCTV which is a monitoring camera or security camera that can record events where the CCTV is installed.

Usually this CCTV is installed in places that are rarely monitored by security or public places that are not often passed by residents.

With the installation of CCTV, it can be expected to be able to prevent theft, destruction, or criminal acts.

CCTV Function

There are several benefits or functions of CCTV that you can feel in terms of security, including:

Prevent Shoplifting

CCTV cameras can help you monitor your shop or place of business outside or inside the room from shoplifters or thieves. It is incomplete if you have security staff but no surveillance cameras are installed in your place of business.

Prevent Vandalism

Vandalism in Indonesia is indeed quite rampant, especially when it occurs in places of business or shops, whether rolling doors or office walls that are painted using spray paint to make graffiti or pasted posters.

Checking recording

Yes, the CCTV function can also make it easier for us to check security by using applications that are connected online using an internet connection.

For Home Owner

CCTV cameras can help homeowners to monitor the activities of people in the house. Usually this CCTV is intended to monitor children’s caregivers.

Insurance Premium Reduction

Implementation of a security system at home, office, or place of business can reduce insurance premiums from 5% to 20%. Because of the security system, the insurance company will dare to give higher premiums in that place.

CCTV History

The history of CCTV was first discovered by an engineer from Germany named Leon Theremin. However, in Indonesia itself, it is still a new technology, so there are still some people who are not familiar with this surveillance camera technology.

Leon Theremin is a physicist from Russia, in 1927 Leon created CCTV because it was to meet the system needs demanded by the Soviet Union.

Initially, CCTV was still using the manual method, namely using a scanning-transmitting camera. There is also a wireless system that requires short waves that use a transmitter and receiver.

Then in 1942 the CCTV system was used by Nazi Germany. Then this system was implemented by Siemens AG and also the Stand VII test. It is used for monitoring the launch of the V-2 rocket.

It was only later in 1949 that this CCTV system was used in general by the Vericon company from the United States.

How CCTV Works

The way CCTV works itself consists of 2 types of cameras, namely analog and IP-based cameras. The most striking difference is in analog technology which still uses a wiring system and control room in place. As for the IP system, which is a modern system with better image quality and also uses an internet connection.

Analog CCTV

Although using a system that is still classic, analog CCTV is still widely used in public and private places. The way this analog CCTV works involves several cameras that are connected to a monitor and recording device or dvr using a cable.

Meanwhile, the recordings are usually stored in a video recorder that can be installed in the recording device. The control room contains a supervisory monitor as well as a video recorder.

CCTV ip camera

CCTV IP cameras have the same way of working as analog systems but have advanced technology compared to analog CCTV. The camera records an image to be forwarded to a surveillance monitor and a server located outside the control room.

This image recording can be sent using a cable or via the internet. However, recording with high definition results will result in large data being sent which is one of the problems with IP systems.

Features on CCTV

What are the features on CCTV? Let’s look at some of the important features available in this product.

Digital Noise Reduction (DNR)

Noise is where the appearance of the effect of rough spots from the recording caused by the camera sensor trying to collect light. With this DNR, the recording will function to reduce the impression of spots and roughness by analyzing 2 images sequentially and removing any noise spots in the last image.

Image Sensor

Image sensor is where the tool on the CCTV camera can be used to capture the recorded image into a signal.

The function of this image sensor is as a retina in the eye that can capture images of objects and pass them on to the brain. So that on the camera sensor there are image elements or what are called pixels.

The sensor will convert the received light into electrons, so the more the intensity of the light the more electrons are formed and the voltage is converted to a number.

Television Lines (TL)

TL or can be called horizontal resolution which is the density of vertical lines on CCTV which is useful for displaying images on the recordings on the screen. So that the larger the TL, the vertical line will be narrower or tighter. The TVL resolution of the CCTV that will appear connected to the monitor or screen.

TVL is the maximum number of vertical dark and light lines that can be counted horizontally with a distance equal to the height of the screen. TVL resolutions that are generally found on CCTV cameras, namely:

  • < 350 atau 320 – 350TVL = low resolution camera
  • 350 – 420 atau 350 – 450TVL = medium resolution camera
  • 450 – 520 atau 450 – 540TVL = high resolution camera

Automatic Gain Control (AGC)

This technology can increase the signal to CCTV cameras in low light. This signal will adjust the image quality automatically to produce a brighter recording that can be seen more clearly later.

You can see the object where the recording is with the right lighting and color. And this technology can adjust the brightness of the recording if the lighting changes every second.

Automatic White Balance (AWB)

This feature produces clear and quality images even in low light. CCTV has this feature automatically which recognizes the temperature and light temperature of the area being monitored.

The AWB feature translates the color of the light which will then produce footage that is easier to view.


Varifocal is a lens that regulates the size of an object. A feature on CCTV cameras which can be useful for zooming in on objects that are less clear, appear closer and clearer.

This feature can also allow you as a user to set the minimum and maximum limits of lens focus.

For example, the camera has a 6mm-12mm varifocal lens, which means that the focus lens is from 6mm to 12mm.

This camera with varifocal lens can be used for indoor and outdoor CCTV cameras. However, a camera with a varifocal lens is more capable when placed outdoors because it has a fairly wide and distant monitoring room compared to indoors.

This type of lens has a focal length that can be varied to provide the exact image you want. This type of lens is similar to a manual zoom lens, but the varifocal lens is not capable of zoom tracking.

Up The Coax (UTC)

UTC or stands for UP The Coax is a technology applied to analog CCTV cameras.

UTC or stands for Up The Coax is a new technology applied to analog CCTV cameras.

UTC allows the user to adjust the OSD (On Screen Display) of the camera remotely using the UTC integrated circuit. This UTC feature has been embedded in the coaxial cable, so that if you want to use this feature, the signal will immediately send via the coaxial cable.

Index Protection Rating

IP rating or Index Protection Rating is an international code that can be used to assess a camera’s resistance to dust, water, and others.

The higher the IP rating on a CCTV camera, the stronger the CCTV camera’s defense against dust and others.

On Screen Display (OSD)

On screen display is a feature that CCTV cameras use to find out the parameters to deviate from the recorded image of the CCTV camera. The OSD can be used to adjust any menus in the camera settings and is attached to the camera cable.

Sense Up

Sense up, also known as shutter speed, is the sensor cover on the camera. When recording images, this shutter will be open for a while so that the camera sensor can record the light that enters the camera lens.

Sense up is a feature that allows users to adjust the speed at which light enters the camera, so that the resulting footage has high sensitivity even in low light conditions.

IR Distance

IR Distance or called infrared distance is a technology that can measure the infrared range of CCTV cameras.

This IR Distance is useful for capturing images in low light environments where CCTV records, especially in low light environments.

IR Distance is really important to choose how far the CCTV camera can capture objects against the night.

Wide Dynamic Range (WDC)

WDR technology is a technology that balances the dark and light in the recording so that it can get pleasing results.

For example, when the light is maximum or minimal, the WDR technology is tasked with balancing in order to produce clear results.

Charge Couple Device (CCD) & Complimentary Metal Oxide Semiconductor (CMOS)

CCD or CMOS are two features of the light capture sensor in CCTV cameras. Cmos has a smaller sensor size but is cheaper than CCD, while CCD has better light sensitivity than CMOS.

This CCD feature has a lower noise filter so that the image recording results will be smoother and not grainy.

While the CMOS feature has a lower level of sensitivity to light, resulting in more noise recording.

This is because cmos consumes less power and CCD consumes 100x more power than CMOS which is no wonder the resulting image quality is better.

Focal Length

Focal length is the focal length between the optical center of the lens and the image recorded on the camera sensor.

The shorter the focal length, the narrower the scope of the camera lens in recording images. Wide angle lenses usually use a short focal length, while telephoto lenses use a long focal length.

Infrared Cutfilter Removal (ICR)

The ICR feature itself has a function in filtering the absorption of heat generated by infrared light waves.

Absorption of light waves aims to give color to an object but this feature will function when there is sufficient light.

If there is not enough light, the ICR will not function properly and will produce features in black and white mode.

Why Do a Body Temperature Check

As stated below at the beginning of this article, it is very important to check body temperature using current tools.

So why should you do this body temperature check? So we need to understand some of the points below.

Body temperature

Body temperature is a measure of the body’s ability to produce and reduce heat. Body temperature can be affected by several things, for example, ambient temperature. The high and low body temperature of a person can be an indicator of a person’s health condition.

Body Temperature Too Low

Normal human body temperature ranges from 36.5-37.2o Celsius, so below that, the body temperature is too low. This is also called hypothermia which is dangerous because it can interfere with the smooth flow of blood, breathing, and vital organs of the body, either the brain or heart.

High Body Temperature

The opposite of hypothermia that high body temperature is hyperthermia where the body temperature rises more than 40 degrees Celsius.

Hyperthermia is different from fever. Fever itself is an increase in temperature that is fully controlled by the body’s temperature regulation system, while hyperthermia is an increase in body temperature beyond the control of the body.

How to Check Body Temperature

There are many ways to check body temperature, from being touched by hand to using a thermometer or using a thermal camera.

Using a Thermometer

There are several types of thermometers to check body temperature, the following:

Mercury Thermometer

A mercury thermometer is a conventional thermometer that uses glass and mercury as a temperature measurement using the chemical reaction method.

Digital Thermometer

Digital thermometer or electronic thermometer made of plastic with a pencil-like tip. So besides being used in various areas of the body, such as the armpits, mouth, or anus, this type is indeed the easiest to read and use.

Ear Thermometer

As the name suggests, this ear thermometer is shaped like a small cone that is used to measure body temperature through the ear, usually this thermometer is equipped with a digital screen that can display the temperature in real time.

Digital Dot Thermometer

This thermometer is shaped like a baby pacifier which is intended to measure the baby’s body temperature. This dot thermometer is less effective because it takes a long time to see the measurement results.

Infrared Digital Thermometer

This thermometer is a thermometer that is able to measure body temperature with infrared light.

Its use is quite easy you just put the sensor to the forehead and can measure body temperature from the head. Usually, we often find this tool in front of supermarkets or shopping centers such as malls.

Using Thermal Camera

In addition to using a thermometer, you can also use a thermal camera that is installed in front of the door to be able to detect the body temperature of someone who passes through it.

This thermal camera is also applied to CCTV surveillance cameras so that it is very easy for us to check the body temperature of visitors.

Why Do Body Temperature Checks?

Checking body temperature during the current pandemic is very important to know and monitor the potential for transmission of Covid-19.

The fever caused by the symptoms of Covid-19, one of which is a high body temperature. So that by utilizing both a thermometer and a thermal camera, it is easier for us to detect an increase in body temperature.

So, here is a more detailed description of how important it is for us to check body temperature below:

Prevention from Covid-19

By knowing that there are visitors who come by checking their body temperature, you can at least prevent the transmission of the Covid-19 virus to all visitors who are still healthy.

Do not transmit symptoms to others

The most visible symptom of Covid-19 to date is a high fever, so using a body temperature checking device will easily detect and prevent that person from transmitting the virus to others.

Creating a Sense of Security in Public Places

With the presence of a body temperature checker, it will create a sense of security around these public places, whether in malls, hotels, tourist attractions, to traditional shopping centers such as markets.


That is a review of why it is important to check body temperature which can avoid the potential spread of the Covid-19 virus.

With technology that can check body temperature easily, you can now use a thermal camera which is much more practical than using a thermometer one by one.
