Thermal Imaging Cameras

In today’s heightened security environment, around the clock intrusion detection is imperative. Thermal imaging solutions answer the call twenty-four hours a day in any weather condition. Because thermal imaging detects energy emitted from all objects without the need of visible light, intruders can be unveiled day or night, through smoke, fog, sand, rain, and snow. These camera systems can be attached to your network using a Camera Server, making it very easy to deploy, control and operate.

These thermal imagers are long wavelength (8-12 micron), infrared video cameras intended for use in all weather applications.

Visible color day/night cameras are repeatedly rendered ineffective by low contrast lighting or blooming bright light conditions; however, HurleyIR Thermal Imaging Systems provide unhindered, real-time scene playback of any security scenario.

All imagers utilize uncooled technology to produce high quality imagery for high security applications. This type of thermal imager will detect thermal activity in total darkness, through smoke, dust, blowing sand, fog and other obscurants.

These Thermal Imaging Systems integrate easily into all site security solutions. We offer several different system controllers, including the more popular protocols. The open architecture from HurleyIR makes it easy to integrate customizes protocols to meet individual needs.

Models Available

There are a wide variety of models available as well as custom configurations. Models include short, medium and long range systems. These Mil-Spec 810-F thermal imagers are available with 52 degree to 3 degree field of view. They can be mounted stand alone, paired with IR visual cameras or combined with a variety of positioners.

Technical Background

The difference between IP type camera and a Thermal Imaging camera
An IR emitter camera uses near IR wave lengths to “illuminate” a dark scene. Since the “near” IR wave length used is not in the true infrared spectrum it has to rely on the visible light spectrum to be effective. IR illuminators actively project the near IR wavelength on a dark scene. A visual CCTV camera fitted with a special near IR filter can “see” more effectively in dark scenes. IR illuminators are limited in their effective working distance and do not see through weather related obscurants or smoke. IR Illuminators also have a short mean time between failures.

FLIR
Thermal imagers are forward looking infrared devices. The F.L.I.R. acronym was generated by our US military where this technology was first utilized. Some of the first thermal imagers were mounted on the front on reconnaissance aircraft, hence the name forward looking infrared or F.L.I.R.

How Thermal Imagers Work
Thermal imagers are imaging devices that detect emitted infrared wavelengths. Simply put, all objects that are above absolute 0º constitute molecular movement. This molecular movement produces energy or “heat”. The heat is emitted not in the visible spectrum but in the infrared spectrum, which is invisible to the human eye. Thermal imagers detect this emitted infrared energy and process the information electronically into a video or “visual” image so that we can “see” the emitted energy. Thermal imagers allow us to see objects in total darkness, see heat signatures left by hand or foot prints and many other scenarios that we would not be able to normally “see” in the visual world
