Outdoor Thermal Network Camera for Perimeter Intrusion Detection

The Thermal Network Camera is in itself a complete solution for perimeter intrusion detection. It is built around a thermal LWIR sensor and on-board analytics for accurate detection of unwanted intrusions. By using thermal vision, detection is possible in all weather, no-light, and difficult lighting conditions.

The Thermal Network Camera comes as an outdoor camera. The embedded ObjectR-Advanced PID is based on analytics certified by i–LIDS® and approved to be used as primary sensor in a sterile zone. Through the web interface, configuration of the ObjectR-Advanced PID analytics is straightforward with either two detection lines or two detection zones.

To get the most out of the PID analytics we offer the VCA Configuration Server. By using a thermal sensor the influence of external factors is limited to a minimum.

Thermal Goggle Binocular

The Thermal Goggle/Binocular is a rugged, lightweight, and powerful InfraRed device that can be hand held or mounted on a headgear. By using the 2x internal digital zoom and adding an optional a-focal germanium optical magnification lens, the Thermal Binocular provides up to 9x long-range thermal surveillance and acquisition.

The uncooled thermal detector and high resolution display provide crisp “white hot” or “black hot” images regardless of ambient conditions. While night vision technology relies on amplification of ambient light or assisting illumination, thermal devices are completely passive, sensing extremely minute temperature differences.

Image can be enhanced by adjusting the brightness and contrast of the display.

Designed for law enforcement, military and commercial use, the Thermal Binocular is ideal for such functions as: reconnaissance and surveillance, perimeter control, search and rescue, vehicle identification, wildlife observation and geo-thermal events.

The History Of Thermal Night Vision

A Thermal Night Vision Device (NVD) is an optical instrument that allows images to be produced in levels of light approaching total darkness. They are most often used by the military and law enforcement agencies, but are available to civilian users. The term usually refers to a complete unit, including an image intensifier tube, a protective and generally water-resistant housing, and some type of mounting system.

Many NVDs also include sacrificial lenses, IR illuminators, and telescopic lenses. Thermal Night Vision devices were first used in World War II, and came into wide use during the Vietnam War. The technology has evolved greatly since their introduction, leading to several “generations” of Thermal Night Vision equipment with performance increasing and price decreasing.

THE EARLY DAYS | GENERATION 0 (GEN 0)

Historically, many armies would not fight at night because the confusion, lack of quality on-time intelligence, and increased communication difficulty made night fighting a very dangerous and very risky proposition. Only the most highly trained soldiers with a well rehearsed plan could take to the battlefield at night with any clear chance of success.

One of the first technologies to enhance vision at night goes all the way back to the end of WWII. The first Thermal Night Vision devices were introduced by the German army as early as 1939. The first devices were being developed by AEG starting in 1935. By the end of World War II, the German army had equipped approximately 50 Panther tanks, which saw combat on both the Eastern and Western Fronts. The “Vampir” man-portable system for infantrymen was being used with Sturmgewehr 44 assault rifles.

Parallel development of Thermal Night Vision systems occurred in the United States. The M1 and M3 infrared night sighting devices, also known as the “sniperscope” or “snooperscope”, were introduced by the US Army in World War II, and also used in the Korean War, to assist snipers. They were active devices, using a large infrared light source to illuminate targets. Their image intensifier tubes function using an anode and an S-1 photocathode, made primarily of silver, caesium, and oxygen to accelerate the electrons.

GENERATION 1 (GEN I)

First generation passive devices, introduced during the Vietnam War, were an adaptation of earlier active GEN 0 technology, and rely on ambient light instead of an infrared light source.

Using an S-20 photocathode, their image intensifiers produce a light amplification of around 1000x, but are quite bulky and require moonlight to function properly.

GENERATION 2 (GEN II)

Second generation devices feature an improved image-intensifier tube utilizing micro-channel plate (MCP) with an S-25 photocathode, resulting in a much brighter image, especially around the edges of the lens.

This leads to increased illumination in low ambient light environments, such as moonless nights. Light amplification is around 20,000x. Also improved were image resolution and reliability.

Later advancements in GEN II technology brought the tactical characteristics of “GEN II+” devices (equipped with better optics, SUPERGEN tubes, improved resolution and better signal-to-noise ratios) into the range of GEN III devices, which has complicated comparisons.

GENERATION 3 (GEN III)

Third generation Thermal Night Vision systems maintain the MCP from Gen II, but now use a photocathode made with gallium arsenide, which further improves image resolution. In addition, the MCP is coated with an ion barrier film for increased tube life. The light amplification is also improved to around 30,000-50,000x.

THE TRUTH ABOUT GENERATION 4

Some say that generation (Gen) 4 is the most advanced Thermal Night Vision you can buy. This is not the case. To dispel this myth, let’s start with the basics. There are four Generations of Thermal Night Vision; however, they are Gen 0-3, not Gen 1-4. Historically, the U.S. Army has defined each Generation of Thermal Night Vision. In the late 90’s the Army did define Gen 4 as the removal of the ion barrier film creating a “filmless” tube. This new advancement was to reduce halos while increasing sensitivity, signal-to-noise ratio (SNR) and resolution, for overall improved performance. While performance was improved, the lack of an ion barrier in Gen 4 tubes led to high failure rates, ultimately leading the U.S. Army to recant the existence of Gen 4 definition. Recognizing the high failure rates of Gen 4 tubes, ITT chose to improve upon the existing Gen 3 technology and create a “thin-filmed” tube. By keeping the protective ion barrier, but greatly reducing its thickness, ITT was able to maintain the reliability of Gen 3 while at the same time delivering on the Army’s performance requirements intended for Gen 4. This innovation resulted in the production of the Gen 3 thin-filmed tube, which is now the highest performing Gen 3 tube available.

Advantages of Thermal Imaging

All objects, both natural and manmade, emit infrared energy as heat. By detecting very subtle temperature differences of everything in view, infrared (or thermal imaging) technology reveals what otherwise would be invisible to the naked eye. Even in complete darkness and challenging weather conditions, thermal imaging gives users the ability to see the unseen.

First developed for military purposes, thermal imaging has since been adopted by law enforcement, fire and rescue teams, security professionals, maintenance operations, and more. This technology can be used to detect approaching people or vehicles, to track the footsteps of a fugitive, or to learn why a fire resists extinguishment.

  • For law enforcement and security staff, thermal imaging detects suspicious activity over long distances in total darkness and through fog, smoke, dust, foliage, and many other obscurants. This allows officers to approach in stealth mode and make better informed decisions more quickly. Cameras may be handheld, vehicle-mounted, tripod-mounted, or weapon-mounted.
  • For security and surveillance systems, thermal imaging cameras complement CCTV cameras to provide comprehensive threat detection and integrate seamlessly with larger networks.
  • For predictive maintenance, thermal imaging reveals “hot spots” where failure may be imminent in many electrical and industrial facilities and installations.
  • For manufacturers, thermal imaging camera cores are small, light, and have flexible/intelligent designs for easy integration.
