Ultra Long Range Thermal Cameras

For extra-long range applications to protect any high asset value property, our ultra long range thermal cameras are the best choice for security, as it uses a broad range of uncooled and cooled thermal cameras, combined with video and security radar.

Thermal Imaging

Using the latest technological advances, Security Radar brings Silent Sentinel’s affordable thermal imaging technology to commercial surveillance and security applications. All models are designed to operate without ambient light or illumination and will provide excellent image quality in challenging environments. All can be used as a standalone security device or to enhance the capability of any video surveillance system.

The ultra long range thermal Imaging cameras measure heat and convert it into a visible image which makes it ideal for zero light surveillance, and will operate in all weather conditions, even fog. The cameras provide a high contrast image which is perfect for video analytics and motion detection. Radiometric models will give an alarm output when a parameter is breached.

Security Radar has a very extensive range of thermal imaging cameras for all applications. When combined with a video camera and radar, the best features of radar, video and thermal are combined to provide the user with a surveillance device to capture any event.

Oculus Thermal Camera System

The Oculus is a professional vandal-resistant, high-speed continuous rotation pan–tilt–zoom (PTZ) camera. The housing has been cast in aluminium which is then anodised and powder coated to allow the unit to be installed in harsh and challenging environments. The toughened glass viewing window is optically correct and distortion free to provide brighter, clearer images even at full telephoto zoom range. The range is available in both video and thermal imaging options, with or without IR and White light illumination, and all models have a wiper as standard to keep the glass free from a build-up of dust or debris. It is an all-round performer and with its multitude of camera options, it will perform in all weather conditions.

Aeron Thermal Camera System

The Aeron pan–tilt–zoom PTZ camera is designed to meet the increasing demand for long-range thermal and video surveillance in a discreet but, robust housing. Building upon the successful Oculus base frame the Aeron is a compact, rugged continuous rotation PTZ camera. The Aeron incorporates all of the mechanical advantages renowned in the Oculus with the ability to incorporate thermal cameras with larger lenses of 100mm and 100mm optical zoom. This increases man detection up to an impressive 3000m with the option to optically zoom for closer inspection. Video verification is provided by either HD or SD video zoom camera with simultaneous output to the thermal. Aeron can now be supplied with radiometric thermal cores for fire detection.

Osiris Thermal Camera System

The Osiris pan–tilt PT platform is specifically engineered to handle larger and heavier camera units. It is the big brother to the Oculus and
incorporates all of the benefits while also giving the user the option to use a multi-sensor approach in hi-security applications when accurate positioning and long-range detection is required. It is available with 3 off-the-shelf camera housings to allow lenses of up to 700mm to be incorporated within a robust IP67 enclosure. Just like the Oculus, there are a multitude of camera models, including low light and thermal and illumination using LED and laser technologies to ensure images can be seen in all weather conditions, including mist, fog and desert storms.

Jaegar Thermal Camera System

The Jaegar pan–tilt PT platform has a built-in through shaft that allows radars or other payloads to be mounted on top and remain stationary as the PT surveys the scene. A wide range of thermal and video cameras are available, all supplied in cable managed housings for protection in the harshest environments. With harmonic drive gears as standard, the Jaegar is virtually zero backlash ensuring the capture of stable images even at very long distances over land or water. When twinned with radar and absolute positioning control the Jaegar can be driven automatically to any threat detected and remain on target as the threat moves. As with all Search Radar’s products the Jaegar can easily be deployed as a standalone system or combined to increase the performance of existing systems.

What is Specialist surveillance?

SWIR security camera

Short wave infrared (SWIR) cameras offer considerable benefits where atmospheric conditions such as rain, fog, and mist are common. These conditions typically blind visible cameras. InGaAs SWIR technology is capable of seeing through all but the most severe conditions to provide highly accurate images. SWIR cameras also provide exceptional low light performance, essentially providing high-quality images in all but total blackout conditions.

Thermal Imaging camera options

Thermal sensors and cameras create video images from infrared (heat) waves.

Infrared is a part of the electromagnetic spectrum with wavelengths that are longer than visible light. Infrared is typically divided into near, mid, long and extreme and is measured in units known as microns or nanometers. Thermal technology detects infrared energy in the mid-wave infrared (MWIR) spectrum at 3-5 microns or long-wave infrared (LWIR) at 8-12 microns. Day or night, in any environment, every person, object and structure emits infrared waves.

The warmer an object, the more energy it emits. Infrared energy emitted by a viewed scene is focused through the specialized objective lens assembly of an infrared camera on to the camera’s focal plane array (FPA). The FPA uses materials that respond by generating electrical impulses when infrared energy strikes it. These electrical impulses are then sent in the form of temperature values to an image signal processor that turns them into video data for presentation on a display.

Thermal technology provides clear, high-resolution images through smoke, haze, dust, light fog or even on the darkest night, so it often is the perfect choice for 24-hour surveillance. For example, thermal cameras can pick out vehicles that have been driven recently and still have warm engines or ground that has recently been disturbed by footprints or by burying hidden objects.

Uncooled thermal imagers use detectors that are either stabilised to temperatures between -30°C to +30°C or are not stabilised at all.

Benefits of uncooled thermal:

  • Low maintenance 
  • Lower costs
  • Reliable

Two types of thermal technology are available, each with its own advantages.

For some applications, especially for long range detection, it is advisable to use “cooled” sensors. These sensors utilise a highly efficient cryogenic cooler that enables the detector to sense smaller differences in infrared emissions. Cooled technology can often capture images at a greater distance, produce a higher-resolution image and operate with smaller optics.

Cooled thermal imagers use detectors that are cooled to temperatures of 77 degrees Kelvin (roughly -200°C) or lower.

Benefits of cooled thermal:

  • Very sensitive to temperature change
  • High sensitivity = longer range
