With the growing demand for security and protection, the security‑protection market keeps expanding. Security products are updated at an accelerating pace and come in a wide variety. The infrared camera is a new‑type surveillance product that integrates network technology with security‑protection technology. Its emergence has solved many common security‑related problems in daily life. Do you know what components make up an infrared camera? This article gives a detailed introduction for your reference.

Main Components of the Infrared Camera

1. Image Sensor Chip: Serving as the "eye" of a surveillance camera, the image sensor chip directly determines image quality. This is especially critical for infrared cameras operating under low‑light nighttime conditions.
2. DSP Processing Chip: If the image sensor chip is the camera’s eye, the DSP chip acts as its "brain". It not only controls CCD signal acquisition but also performs signal spectrum analysis, digital filtering, intelligent analysis and other operations.
3. Infrared LED Supplement Light Board: Infrared cameras commonly adopt infrared supplementary lights with three wavelengths: 810 nm, 850 nm and 940 nm.
4. Lens: Ordinary non‑IR‑sensitive lenses may suffer focal‑point shift because visible light in daytime and infrared supplementary light at night fall in different spectral bands. This results in sharp images during the day but blurry footage at night.

The above are the key components of an infrared camera, each with unique functions and purposes. Proper care should be taken to protect these vital components in daily operation.
