Could a Thermal Camera System be Right for Your Security Needs?

Most popular security camera systems use passive infrared sensors (PIRs) to detect and visible light to capture imagery of trespassers, thieves, squatters and vandals. But what if your site has long perimeters, limited visible light – or plenty of dark places to hide? There are many situations where it can pay to consider the balance between visible light and thermal image capture and detection.

Where once this technology was largely exclusive to military purposes, thermal imaging cameras are now a valid option for almost any application.

When are infrared thermal cameras an effective choice?


Infrared imaging works differently to visible light imaging in that it detects infrared energy, or heat, and converts it to an image that can be analysed. Humans, animals, vehicles with their engines running and anything else emitting heat may show up in contrast to cooler surroundings. There are multiple benefits to capturing thermal data on a site:

  • The shape of humans and animals can typically be identified even through smoke, fog and dust
  • If someone steps behind foliage or into a shadow, the camera could still pick up their presence
  • Quality thermal cameras can capture an extensive depth of field, which can be superior to even the highest quality visible light cameras
  • Infrared thermal cameras can effectively capture data that might not be captured by a visible light camera: particularly for dark and unlit sites, or where light conditions change dramatically.


In a Spectur wireless infrared security camera system, this technology can aid in the detection of humans and vehicles to alert security personnel to activity onsite. The thermal imaging system can detect movement of people or vehicles in total darkness with confidence up to 200m away.

Why not use both visible light and thermal imaging data capture?


Of course, a combination of visible light and infrared thermal imaging may be more effective than each option alone (which is what Spectur does). Thermal and visible light cameras configurations are used across infrastructure, government, construction and industrial applications to keep a ‘clearer’ eye onsite, combining the power of both technologies to enhance detection capabilities.

Finding the right outdoor security camera with night vision


If you’re looking for a night vision security camera or thermal imaging option, it’s important to consider sensitivity, range, field of view and other specifications. We can help you to choose the ideal solution to suit your needs from our HD5 and STA6 models; from ultra low light cameras, to high-range infrared capabilities that can detect up to 200m and beyond in complete darkness.
