SWIR, MWIR, and LWIR are the three infrared bands used in industrial and security thermal imaging, distinguished by wavelength (1.4–3 μm, 3–5 μm, and 8–14 μm respectively). SWIR is a reflected-light technology suited to material inspection and through-glass viewing; MWIR and LWIR are true thermal-ra Read More

Electronic Image Stabilization (EIS) and Optical Image Stabilization (OIS) are the two primary stabilization technologies for CCTV cameras. EIS is a software-driven, cost-effective method that crops and shifts pixels after capture, well suited to dynamic, well-lit scenes. OIS is a hardware-based met Read More

An IR camera (short for Infrared Camera) is a camera that sees heat instead of visible light.It is a specialized optoelectronic device that detects infrared radiation (invisible to the human eye) emitted or reflected by objects, converting it into visible thermal or night-vision images. Unlike visib Read More

Thermal detectors are the core core components of infrared thermal imaging systems, responsible for converting infrared thermal radiation emitted by all objects in nature into detectable electrical signals. According to whether low-temperature cryogenic cooling equipment is required during operation Read More

Aperture controls how much light reaches a CCTV camera's sensor and how much of the scene stays in focus (depth of field). Selection should be driven by three factors: site lighting levels (lux), depth-of-field requirements, and the target DORI performance level (Detection, Observation, Recognition, Read More

Quick SummaryThermal distance is the long-range passive detection range of a thermal camera, capturing natural long-wave infrared (LWIR) heat radiation with no light source needed — typically hundreds of meters up to several kilometers. IR distance is the short-range active monitoring range of a cam Read More

NETD (Noise Equivalent Temperature Difference, in mK) is the target-background temperature difference that produces an output signal equal to a thermal camera's RMS temporal pixel noise — the core metric of thermal sensitivity. It is measured against a precision-controlled blackbody radiation source Read More
