With Long range PTZ or pan / tilt / zoom thermal imaging becoming relatively cheaper and an integral part of Short, medium, long and extreme ultra long range Surveillance, security, observation systems, a whole range of uses becomes both possible and economically viable. long range Thermal flir PTZ cameras can be an excellent complement in many situations where conventional cameras diminish their performance as low light levels are present. They are, of course, unparalleled in a situation of twilight, thermal cross-over, near darkness and total darkness. They can also be an option in areas that are very difficult to illuminate effectively, for example a sea front, a harbor, or any other vast expanse of open water thus making SPI’s long range PTZ thermal infrared imaging Ir cameras paramount for use in marine, boat, vessel and ship applications.
Similarly, artificial light not only runs the risk of revealing where the cameras are placed, enabling parties to avoid or vandalize them, but can also create projected shadows in which an intruder can avoid detection. Furthermore, spotlights can blind as well as illuminate. So cameras that do not rely on light can be the preferred solution in many different traffic situations, whether it is in railway tunnels, on air strips, runways, or on regular streets. Long Range Thermal flir PTZ cameras, on the other hand, cannot be blinded by bright lights or laser beams.SPI Corp’s long range multi sensor Eoir flir thermal imaging camera systems offer substantial long distance detection ranges allowing the operator to be positioned at very far distant standoff locations offering ample time to react, to threats or targets of interest.

Long range thermal camerasLong Range Visible HD CCTV cameras can compliment the Thermal cameras and assist in daytime and low light DRI (Detection, Recognition and Identification)Long range Critical infrastructure applications require not only continuous video surveillance and monitoring, but also a solution that yields highly reliable intrusion detection, with fewer false alarms. This need makes advanced video analytics a must for any adequate long range thermal/cctv surveillance system.ANALYTICS, IMAGE CAPTURE, ACTION AND NETWORK SUPPORTABILITY.
long range thermal ptz camera
Advanced analytics will provide multiple automated alarm notification options, including email, edge image storage, digital outputs or video management software (VMS) alarms. Incorporating high quality, unique and adaptive analytics can virtually eliminate false alarms, allowing security personnel to respond more efficiently and effectively, while also lowering overall cost for the end user. Once a long range intrusion attempt is discovered, it is important to act fast. Organizing a response system that can initiate actions based on GPS location data, such as the slewing of the Long range thermal cameras, automated intruder tracking or activated lighting sensors, greatly increases staff’s situational awareness while easing their workload. For instance, thermal imagers deployed in conjunction with video analytics can be used to generate an initial alarm event, which can then trigger a sequence of other security equipment and notifications for personnel to eventually respond to. Having all of this in place essentially lays the entire situation out in a way that allows responders to accurately understand and evaluate a scene.
long range thermal ptz camera
While traditional long range surveillance & security technologies such as radar, Long range thermal cameras and visible cameras, or video analytics work well on their own, utilizing all of these options together provide an advanced perimeter detection system. For example, ground surveillance radar can detect possible threats beyond the fence line as they approach and send a signal to pan-tilt-zoom (PTZ) cameras, triggering them to slew to a specific location. From there, embedded analytics and visible cameras can further identify objects, notify authorized staff, and collect additional evidence through facial recognition or high-quality photos and videos, Post auto-response mechanisms have activated and done their job, it is time for responders to acknowledge and assess the situation. From here, authorized personnel can take the next appropriate step toward defending against and delaying the threat.
long range thermal ptz camera
Deterring suspicious activity can be achieved through real-time two-way audio, a simple but powerful tool. Often, control room operators can diffuse a situation by speaking over an intercom, telling the trespasser that they are being watched and that the authorities have been notified. The primary purpose of the delay facet of the overall perimeter protection strategy is to stall an attempted intrusion long enough for responders to act. Access control systems play a key role in realizing this objective. When a security officer sees a non-compliant, suspicious individual on the camera feed, the officer can lock all possible exits to trap them in one area all through the VMS.
MWIR and LWIR reference overview, Long range thermal cameras such as the M7 Flacon is an ideal sensor for 24/7 all-weather surveillance often used in protected environments such as a border or an airport. Quite often it is difficult to decide between
a thermal camera active in the cooled mid-wave infrared spectral band (MWIR 3-5 micron) or in the long-wave infrared spectral band (LWIR 8-12 micron).
Here’s a quick break down of the technical differences between the two, with comparative costs and benefits associated with each that may help
you decide on the most appropriate technology between Long range thermal cameras that are cooled MWIR and uncooled LWIR.

Some basic physics first. The infrared spectrum is usually divided into three bands that correspond to three atmospheric transmission windows:
SWIR = ~1-2.5μm short-wave infrared Uncooled
MWIR = ~3-5μm mid-wave infrared (thermal) Cooled
LWIR = ~7-14μm long-wave infrared (thermal) UncooledLet us focus on the last two spectral wavelength bands, MWIR and LWIR, which are referred to as the ‘thermal imaging bands’, as the long range thermal cameras in these bands are actually making an electronic image that corresponds to the thermal gradients in the observed scene.
Overall atmospheric transmission The overall atmospheric transmission depends on the local atmospheric constituents (aerosols, particles, water vapor, fog, rain etc).
long range thermal imaging MWIR camera systems are less affected by humidity than long range thermal imaging LWIR camera systems for most target ranges, so we would usually recommend MWIR cameras for applications like coastal surveillance, vessel traffic surveillance, shoreline, frontier and border or harbor protection.
Both bands are adversely affected by fog and rain, though LWIR band has better performance than MWIR in fog conditions.

LWIR band is better than MWIR for imaging through smoke or aerosols, so LWIR is usually the chosen technology for firefighting applications and for military applications.
Nevertheless, for very long-range target detection at 10km distance or more, MWIR has greater atmospheric transmission than LWIR in most climates. For that reason, MWIR is usually the preferred choice for very long range surveillance applications.
Target temperature (thermal flux, contrast, spectral content)
For most of the long range surveillance situations (man or vehicle to be detected within ambient temperature background), there is more flux (thermal energy emitted by the targets and by the environment background) available in the LWIR band than in the MWIR band at most scene temperatures, (around ambient temperatures).
However, the thermal contrast (target flux normalized to background flux), which actually makes the thermal image, is usually greater in the MWIR cooled band, this is one of the reasons why MWIR
is often the preferred choice when customers can afford for SD and HD / 4k long range thermal cameras. Moreover, MWIR is also a better option for midwave 3-5 micron long range thermal cameras if you want to detect airplanes or missiles. Bright IR hot exhaust plumes are significantly more visible in the MWIR with SPI 3-5 micron long range thermal imaging cameras than in the LWIR thermal cameras.
Solar effects LWIR sees negligible solar effects while MWIR
does, so a LWIR long range thermal camera can provide more consistent images between day time and night time. However, please make sure that your LWIR long range thermal flir camera is resistant to direct exposure to the wsun, and in fact some of the low cost un-cooled microbolometers can have their detector ‘burnt’ by a too much or too direct exposure to the sun.
Long range thermal imaging camera
Inversely, while most of the MWIR long range flir cameras current technologies are ‘sun immune’, the actual MWIR performance can be deteriorated by solar glints, for example the sun reflecting off water can hide targets in case of coastal surveillance. The last but not least factor is price. As often,
the technology performance is proportional to the budget. This fact is globally true for long range thermal cameras with un-cooled LWIR cameras (very affordable today much like the M7 Falcon, good enough for most of the short and mid-range applications), cooled long range MWIR cameras (expensive, for long range surveillance) and cooled LWIR Long range thermal cameras (usually very expensive, for long-range application or specific military usage).

In short cooled MWIR and uncooled LWIR Long range thermal vision flir cameras are an incredible tool for detecting, identifying and recognizing threats at vast distances, in extreme low light level, harsh environments. NVTHERM can help characterization. The system is ideal advanced exotic applications like EOIR, ISR, FOD (Foreign Object Detection) preventive, predictive maintenance as well as a wide range of security and surveillance.
The M7 Falcon long range thermal vision camera utilizes the more affordable LWIR thermals. The same system in MWIR would cost about 4x the price.
