Abstract: The disclosure provides a camera module, a monitoring system and a vehicle camera, the camera module includes a lens barrel, a first lens and a heating element, the lens barrel includes a light entrance, the first lens is disposed at the light entrance, the first lens includes an image side surface, the heating element directly acts on the image side surface to heat the first lens. By directly applying the heating element to the image side surface of the first lens, the heating element can directly transmit heat energy to the first lens, thereby achieving the effect of defogging and defrosting automatically.

Abstract: The disclosure provides an infrared optical imaging lens, a camera module and a DMS. From an object side to an image side along an optical axis, the infrared optical imaging lens sequentially includes a stop, a first lens with a positive refractive power, a second lens with a positive refractive power, a third lens with a negative refractive power, and a filter. An object side surface of the first lens is convex, an image side surface of the first lens is concave. An object side surface of the second lens is concave, an image side surface of the second lens is convex. A paraxial portion of an object side surface of the third lens is convex, and a paraxial portion of an image side surface of the third lens is concave.

Abstract: Provided is an infrared optical imaging camera lens and an imaging device, said lens comprising sequentially along the optical axis, from the object side to the imaging side: a diaphragm; a first lens basing positive focal power, the object-side surface of said first lens being a convex surface and the image-side surface being a concave surface; a second lens having positive focal power, the object-side surface of said second lens being a concave surface and the image-side surface being a convex surface; a third lens having negative focal power, the object-side surface of said third lens being a convex surface in the region near the optical axis and the image-side surface being a concave surface in the region near the optical axis; and an optical filter.
