Fixed Mount Thermal Imagers

Fixed Mount Thermal Imagers

Fixed Mount Thermal Imagers are multi-sensor Thermal Imaging Cameras primarily intended for indoor and outdoor security applications. They are used to detect intruders and other threats to a facility's security. Imagers can detect the existence of heat in a totally dark environment and inclement weather. The cameras provide both simultaneous visible-light and thermal video outputs to insure constant security and surveillance in your facility or on your property.
 
Thermal Imagers for Security are also used by Law Enforcement and Fire Fighting in order to locate criminals, casualties, and hazards. They provide security in total darkness, smoke, fog, and fire. Thermal Imagers are used to measure surface temperature and temperature differential of surrounding areas for Commercial, Industrial, General, and First Responder Use. They are now considered to be an essential tool utilized in many first responder applications including, but not limited to, Law Enforcement, Fire Fighting, Marine Safety, and Home Land Security. They are now used and accepted worldwide for Security, Safety, and Enforcement Searches. They are considered to be extremely powerful weapons that can be used by officers and emergency personnel in the fight against crime. The use of thermal cameras offers officers and fire fighters a tactical and search advantage. A Fixed Mounted thermal imager allows increased security of property and personnel as well as the observation and location of possible criminals and suspects, without revealing the officers’ location in total darkness or through smoke, moderate fog, and behind foliage. Thermal Imagers also increase the likelihood of identification and capture of a suspect, improving ability to track and collect important evidence, increasing the probability of locating injured or hidden casualties in a fire, as well as locating the source of high temperature and possible danger. First Responders and Law Enforcement Personnel depend on having the shortest reaction time in order to gain information and to be able to assist, save, or apprehend. Utilizing a Fixed Mounted Imager offers much greater security and possible identification of intruders or criminals. Utilizing a high count pixel array with a long “field of view” lens allows information to gathered and recorded and transmitted quickly.
 
Some of the unique features include lens selection to obtain a selection of “field of view” distances, as well a choice of IR Resolution (pixel array) and mounting choice. A dome-up camera model can be mounted on top of the mounting surface. A dome-down camera model can be mounted under an overhanging mounting arm, or underneath an overhanging mounting surface such as eaves or an awning.
 
These cameras also allow precise pan/tilt control and fully programmable scan patterns, radar slew-to-cue, and slew-to-alarm functionality.

Applications

• Critical Infrastructure
• Law Enforcement
• Nuclear Power
• Petrochemical
• Seaports
• Borders
• Commercial Buildings
• Warehouses

• Residential

Features

• See objects, suspects, obstacles, animals and any heat source in total darkness
• Enhances Security vision in total darkness 
• Installed in either “dome-up or dome-down” for ease of mounting for all surveillance
• See heated objects through smoke 
• Enables vision at night during Pursuit
• Temperature can be seen in dark…so can suspects and dangerous situations be noted and reacted upon.
• Monitor the activity of suspects without their knowledge and in total darkness
• See through smoke, allowing officers to respond safely and quickly

See hazards and perpetrators from an offsite position enabling lives to be saved and property to be protected.

IR Resolution (Pixel Array) / Detector Size

Although for Fixed Mount Thermal Cameras the Detector Resolution selection is limited to one choice, it is important to understand more about Detector Resolution. Detector resolution is based on the pixel array that each camera contains. Using larger pixel arrays, (as well as the lens “Field of View” selected and any special electronics being added to the optical circuit), cameras can measure smaller targets at a longer distance that would be sharper and in greater detail. All cameras display temperature gradient. As the pixel array increase in size, the average temperature spot measured becomes smaller. This will increase the information gathered by the camera.

When discussing pixel size, the specific application must be taken into consideration. Please be aware that the detector resolution is different than the display resolution. It is the detector resolution that matters the most. Higher resolution thermal imaging not only provides more accurate quantitative results, but it is also very important when presenting those results to customers. Please see FOV, “Field of View” paragraph below. Given a fixed pixel array, the FOV will determine the detail of temperature being displayed.

FOV - Field of View

Like the Detector Size above, the FOV or "Field of View" selection is limited to one choice. But it was optimally chosen for viewing at a distance. The FOV is the area of the image that is measured and viewed on the imager screen. The lens has the greatest influence on the total view, but a larger pixel array (matrix) may provide greater detail of desired temperature gradient. Compare the following illustrations.

   

Review

Compare the application you desire for security, the placement of the cameras and the “field of view” you would like and the resolution required. This will enable you to determine the best camera and lens for your facility and purpose.
