Understand more about how Thermal Cameras can detect fevers and why it has become so important


With the current Covid 19 crisis the importance of detecting potential victims of infectious or contagious diseases cannot be over-emphasised. 

Screening visitors arriving at your office or any location where such a problem is known to exist and checking them for simple fevers such as colds or influenza or something more serious needs a quick and effective system. A number of vendors now offer  thermal imaging cameras.

We hope to highlight the important use of infrared thermography in screening and detecting abnormal temperatures in large numbers of people.


Thermal cameras have proved invaluable in detecting actual and potential defects in a wide variety of electrical, mechanical and building industries and now this type of technology is being use in veterinary care in recent years.

Medical applications are increasing as the ease of use in detecting higher than normal temperatures in people suffering from a number of causes.

None of these is more important than finding those which may be caused by fevers in cases of viral diseases such as SARS or Ebola

Located in border crossings such as ports and airports thermal cameras can be used by trained operatives.  Anyone with a raised temperature is passed over to medical staff for further investigation and detained from leaving the facility and, possibly stopping the spread of infection.

The vast numbers of people now travelling has increased the risk of the rapid spread of infectious diseases at the same time as making it more difficult to single out individuals for temperature checks.

Thermal cameras can be used to scan a number of people at once. Anyone showing an abnormal temperature stands out from the crowd and can be asked to move to a quieter area for a more accurate check. If this proves positive they proceed to the next step of medical checks.

In this application, the thermal camera operates by converting the energy emitted from the surface of the skin into a two-dimensional image with the differing temperature levels making a colour picture. The camera is calibrated so that an abnormal temperature is very easy to detect and recorded. If required an audible or visual warning can be given.

What are the Advantages of using a thermal camera for fever detection?

The advantage of this method is that the time taken to get an accurate assessment of the visitors is very quick without causing extra delays to consumers arriving or leaving,  this makes thermal imaging beneficial for everyone.

Access control systems help prevent thefts on construction sites

Access control systems are just one of the series of security solutions that can be deployed to prevent thefts on building sites, a phenomenon that is affecting an increasing number of construction companies across the UK.

In fact, the Construction Index reports that more than half of builders in the UK have been victims of theft, with more than 50% having had their vans damaged and tools stolen.

In an interview, FMB chief executive Brian Berry stated that tools were being stolen from vans and directly from construction sites. “Some builders have even been assaulted by would-be thieves. The impact of this on the nation’s smaller building firms is particularly disruptive. Not only is there a high cost in terms of both time and money spent replacing these expensive tools, and to fix the damage caused, but without the right tools, firms are simply unable to work,” he explained.

Builders are currently adopting a range of measures to limit tool theft. This can range from bringing tools inside after work, installing extra locks on vans and parking against a wall.

Leaving tools, no matter how big or small, lying around a construction site after work hours is like leaving out an invitation for thieves. Professional Builder suggests locking everything away in safe storage or taking the tools and equipment off-site. If the tools are too big, marking each with indelible ink or an identification mark can help in the recovery, especially if the equipment is listed on a police-approved national tool register. 

If you do leave the tools on-site it pays to invest in a good quality shed to store them in. T3’s guide to choosing the best shed details how metal designs are more resilient than wooden sheds. This means that they will last longer on a construction site. In terms of security, a metal shed would be much harder to break into. Of course, it is up to the builders to make sure the shed is secure with good locks. Screwfix has a number of metal sheds that now come with two padlock points, which will allow builders to have an extra level of protection. It is also best to purchase a shed without a window, which would be an easy access point for thieves. A metal shed can also be constructed and broken down much quicker than a regular wooden shed, meaning it could be transported easily from site to site. 

Go digital

Electrical Contractor Magazine notes that digital advancements like mobile technology and artificial intelligence have made it easier for contractors to monitor multiple locations at a time. Security cameras can now be controlled through mobile phones by simply downloading an app; these allow contractors to view the site 24/7. Not only that, installing tracking devices on tools is now an option. Cloud-based software can help track tools that have been fitted with a tracking device. This means a contractor can now monitor when the tools are being used and in some cases where they are.

Protection against theft on construction sites needs to start at the site boundary by incorporating physical deterrents like strong walls and perimeter fences. Intruder alarms, high-quality locks, and controlled entry points are also great deterrents.

If it is a large site, then controlled entry points and patrols can also help make sure no one is on the site during the hours when it is closed.

CCTV cameras are everywhere in the UK and are considered one of the most efficient tools in preventing crime. But only if they work.

In order for CCTV cameras to be beneficial, they need to be correctly installed and maintained. If you stroll through any city and look closely, you will notice cameras everywhere. This may make you feel safe. But how many of them are truly capable of providing you with security?

Correct CCTV installation is not only about where the camera is placed, but also about how it is placed there, how it is connected to the rest of your company’s security and data systems, how the pictures are archived and who has access to them.

In other words, your CCTV system needs to be seamlessly integrated with your other management and ITC systems. They need to work together as a well-oiled machine in order for you to get the best possible results.

Not only do these elements make the difference between footage that can catch a criminal and footage that shows nothing useful, but many of them constitute legal requirements that fall into your responsibility.

Faulty CCTV deployment can incur huge costs in fines and damages suits. Even more, if your system isn’t properly installed, you may not use the footage as evidence when you need it the most. Last, but not least, what good is a CCTV system if it’s not thief-proof? Proper installation ensures that your system is not easy to tamper with and render it useless.

In CSC’s twenty years of experience of CCTV systems installation in commercial buildings, we have come across – and learned from – many CCTV deployment mistakes. In today’s post, we are going to talk about the most dangerous ones – the basis of the most important lessons we have learned.

1. Ignoring Environmental Factors in Monitored Areas

Ignoring environmental factors in monitored areas is the most common mistake made in CCTV deployment. The most intuitive example is ambient light level: insufficient or radically unequal lighting can result in undecipherable footage.

Other factors that you need to consider are:

  • Humidity, dust and vibration, which can severely impact the lifetime of the CCTV cameras, their storage media and their cabling.
  • Electronic / Magnetic interference, which may require special provisioning for long-distance data cables.

Environmental factors should play a role when planning deployment, selecting equipment, and installing the system. Even indoors equipment is susceptible to bad lighting conditions or electrical interference, so you should not ignore these concerns simply because your company’s offices are in an air-conditioned, clean glass building.

We carefully plan each installation and factor in environmental conditions before making any decisions or drilling any holes.

2. Ignoring the Monitoring and Storage Areas

Most CCTV users are primarily concerned with what they are monitoring, so they focus primarily on the cameras.

If live monitoring is required, the operators have to work from a secure room, where access is strictly controlled and logged. This room needs to have an adequate size and lighting, and – since the equipment usually generates a lot of heat – adequate ventilation and temperature control. In fact, some businesses opt to do the live monitoring off-premises.

Even if live monitoring is not accessed, the recorded pictures need to be stored and archived in a secure location, as businesses are legally responsible for the security of their CCTV footage.

Make sure that your storage room is not affected by humidity and that it’s perfectly safe from extreme weather conditions.

3. Treating CCTV and IT Infrastructure Separately

Infrastructure convergence is no longer something that security professionals are debating. Even large enterprises, where physical security and IT have been separate functions virtually throughout the history of IT, are no longer talking about whether it makes sense to treat them together, but about how they can optimize this convergence.

Maintaining a separate network for CCTV equipment, installed separately from the rest of the office network, with separate maintenance procedures and servicing contracts is a significant management and financial burden. It reduces the flexibility of your security systems, while needlessly increasing infrastructure costs. Networking service providers have long recognized this tendency and have begun to offer integrated network design and cabling services.

4. Inadequate Data and Power Cabling

Although physical security and IT are no longer separate functions, they do have specific – and separate – requirements. CCTV cameras have special installation requirements that range from legal restrictions to specific provisions regarding power and data cabling.

Most indoors CCTV cameras today use Cat-5/6 cables for their data connections, just like desktop computers. Higher-speed cameras, or cameras used for outdoors deployment tend to use fibre optic cables, which can carry data at higher speeds and over longer distances. Due to their convenience and ease of installation, wireless cameras are becoming increasingly popular – but even these require power cabling (albeit, if the electrical installation is adequate, over much shorter distances).

However, each type of cable only works over a certain range of distances and has special connection and interoperation requirements – for example, you cannot plug an optical SFP or OFP connector to your office router.

Mistakes made when choosing equipment tend to be costly to repair – and mistakes made while installing the cabling tend to be difficult to troubleshoot.

This is why you should always work with professionals for all your cabling and CCTV deployment needs. It may look cheaper to have a friend who “knows cabling and is techy” do the installation for you. But in the long run, it will definitely cost you a lot more to fix mistakes.

5. No Balance between Security and Maintenance

Good quality CCTV cameras are designed to be sturdy and reliable. If they are properly installed, most cameras end up being replaced due to growing customer demands or technical obsolescence, not because they break.

However, like all security equipment, CCTV cameras do need regular inspection and maintenance. It can be tempting to place cameras in inaccessible locations and permanently seal cables into their enclosures. Indeed, no one will be able to tamper with the cable or the camera – but changing a damaged cable or replacing the camera will be equally difficult.

It is crucial to think about your long-term investment here. Make sure that easy access to cables is granted and that the maintenance and repair teams can intervene quickly when there is a problem to be solved.

6. Not Following Legislation and Police Recommendations

Not following legislation is the single most disastrous mistake you can make when it comes to CCTV cameras. Being recorded at work or in a public place is a problem that everyone takes seriously. Leaking or misusing recorded information can have disastrous consequences for the persons recorded, even when they are not caught doing anything illegal.

This is why the UK has a very strict legislation related to what you can record and under what conditions. The fundamental act which governs how you are allowed to use information from CCTV cameras is the Data Protection Act (DPA) In short, according to the Data Protection Act, if you are using CCTV cameras on your commercial property, you must:

  • Let everyone know that CCTVs are being used and why (usually by putting up a sign announcing that “you may be recorded”).
  • Keep images only as long as your business needs them.
  • Be able to provide images within 40 days to anyone who has been recorded and, if you are asked, to the authorities.

The DPO itself is augmented by a number of other regulatory documents, primarily the Freedom of Information Act (FOIA) and the Protection of Freedoms Act (POFA). These requirements are outlined in the Surveillance Camera Code of Practice, issued under the POFA. The ICO’s handy code of practice also includes a useful, more down-to-earth overview of your responsibilities.

The legislation in this field is very murky and probably best left to experts in matters of law. However, you should at least be aware of its scope, and you should ensure that any third-party you work with is aware of it as well.

7. Bad Storage and Archival Practices

Most CCTV footage is not used immediately after being recorded. At a minimum, many burglaries against commercial properties take place during the night, so it can be hours before someone retrieves the recording. In other cases, it may take days or even weeks before someone notices something wrong and decides to look at CCTV footage, or before an official request from the authorities is delivered.

Consequently, CCTV footage needs to be properly archived. The basic guideline is that your system should be able to store 31 days of good quality pictures; there is rarely any reason to reduce this period, but for some businesses it can make sense to extend it.

Good storage practices are not just about storage capacity though. You also need to keep in mind that:

  • All recordings must be retained in a secure environment with adequate access controls and logging.
  • The tokens used to access secured data (passwords, encryption keys etc.) should be kept secure, only by authorized operators, but must be available at all times. Footage that can no longer be accessed is of no use.
  • Footage should be archived and indexed so that the desired fragment (usually identified by date and time) is easy to locate.

Fortunately, the Home Office issues a leaflet with 19 simple guidelines to follow in order to ensure the quality and safe storage of your CCTV footage.

8. Skipping System Validation

The installation of CCTV systems is often time- and resource-constrained. Many operators are content to just turn everything on and make sure that every camera seems to be recording and producing footage.

This can be sufficient for simple installations, which only have one or two security cameras pointed at the doors. But for more complex installations, this level of validation is dangerous.

Have you ever noticed how “alien” CCTV footage seems – how everything looks warped, how the surroundings look remarkably static and narrow, and how various features are unexpectedly blurry, even though others are crystal-clear?

That is because CCTV cameras have optic parameters that are quite different from those of the human eye. Unfortunately, that makes it hard to verify parameters like coverage and image detail just by looking at a screen for ten seconds.

The Home Office’s CCTV operations manual instead recommends that a set of vital parameters be verified according to a documented test procedure, based on design specifications. These parameters cover features such as:

  • Image parameters: field of view, image detail, live and recorded quality.
  • Integration with any other security system components, such as alarms, access control and motion detection systems.
  • Storage time and quality.

Does all this seem too complex? We’re not going to lie – it can be. Especially if you want to make sure you the CCTV system monitoring your office building is always functioning properly and is not easy to tamper with.

It may be tempting to purchase the cheapest cameras on the market and have your “tech guy” install them, but this will in no way guarantee your safety.
