Explore our core technological offerings engineered for surveillance, temperature measurement, and security applications.
Over the past decade, forensic science has undergone a digital revolution. Traditional investigative techniques are increasingly supported by advanced electro-optical sensors. Among these, thermal vision technology has emerged as an indispensable asset for Crime Scene Investigation (CSI), search and rescue (SAR), and tactical operations globally.
By capturing the mid-to-long wave infrared radiation (MWIR/LWIR) emitted by objects, thermal cameras visualize thermal anomalies that are invisible to the naked eye. In crime scene reconstructions, this technology permits non-destructive, rapid analysis of environments, exposing footprints, hidden compartments, biological traces, and disturbed earth where bodies or weapons may be concealed.
Global law enforcement agencies, including the FBI, Interpol, and European national police departments, have established dedicated thermal imaging protocols. The integration of high-resolution, uncooled microbolometers has made these devices portable, cost-effective, and highly reliable under extreme field conditions, paving the way for ubiquitous field deployment.

Discover how modern forensic investigators leverage LWIR and MWIR spectra to gather high-integrity evidence.
Uncovering graves requires identifying changes in soil structure. Digging disrupts the soil's density and moisture content, changing its thermal inertia. Our thermal vision cameras locate these temperature variances during diurnal transitions, aiding in the discovery of hidden remains.
While chemical reagents like Luminol are standard for finding blood, they can degrade DNA evidence. High-sensitivity thermal sensors scan for latent biological fluid deposits based on micro-evaporation and thermal emissivity differentials, offering a non-destructive alternative.
During active threat or hostage containment scenarios, real-time uncooled thermal modules provide SWAT and response teams with visibility through smoke, dust, and total darkness, identifying the location of suspects and victims before tactical entry.
Smugglers use double-walled vehicles, false ceilings, and underfloor cavities to hide contraband. Because these alterations change the heat transfer properties of the vehicle or structure, thermal imagers can spot these voids during security screenings.
For large crime scenes or wilderness searches, mounting uncooled thermal cores on Unmanned Aerial Vehicles (UAVs) allows investigators to scan hectares of terrain quickly, detecting heat signatures under dense canopy or in hard-to-reach locations.
