Are thermal cameras missing from your security solution?

 

Are you adopting thermal cameras on your site? If not, should you be?

 

Let's take a look at the features, advantages, applications and challenges of thermal cameras to help you understand if this solution could help keep your site safe and secure.

 

 


Features

 

Image

By using differences in temperature to produce an image, rather than using light as cameras do, thermal cameras can produce detailed, accurate images across a large area. Images can be used standalone, or with video surveillance for even better results.

Thermometry

Accurate temperature detection (down to a fraction of a degree) can help identify exceptional or high risk scenarios, such as detecting fire at an early stage or identifying overheating which could cause damage or increase risk.

Smart: analytics element

 

Thermal cameras can be integrated with smart features to automatically trigger an alarm for pre-defined scenarios related to temperature, movement, line crossing, and more.

 

 

Advantages

 

No lighting restrictions

Thermal cameras work well in complete darkness and under challenging lighting conditions, such as shadows, backlight, thick smoke, and with camouflaged or obscured obje­­cts.

 

Good results in unfavorable weather

Thermal cameras work well in challenging weather conditions including thick fog, heavy rain, blizzards, etc.  

 

Accurate detection and few false alarms

Smart thermal cameras produce far fewer false alarms than video surveillance, increading time efficiency for security managers.

 

Wide range

Thermal cameras work well across a large area and can therefore reduce the number of cameras needed to cover an open area.

 

 

Key Applications

  • Perimeter protection and outdoor surveillance – virtual fence and line crossing can be set up with analytics; no additional lighting is needed and large areas can be covered
  • Fire detection and production safety at critical sites such as petrochemical, industrial manufacturing, etc.
  • Accurate motion detection in challenging lighting conditions
  • Body temperature detection in schools and airports
  • Identifying overheating wires and effectiveness of cooling systems in data centers for safety, failure prevention and to identify where energy is being lost

 

Challenges

  • Some conditions such as extremely dense fog, very heavy snowfall and reflections from water may result in poorer images
  • Images can be affected by surroundings or background since thermal cameras cannot distinguish between an object and its surroundings
  • Cost can be high so it is important to assess needs, the value that will be added and how thermal cameras can best be adopted at your site

 

Conclusion

 

Thermal cameras can dramatically boost security and safety when applied correctly in a scenario that can add value. As with each aspect of your security, it is important that your thermal solution is integrated with other aspects of your security solution for the best results.
