The invention relates to an all-weather integrated camera protective hood, which comprises a protective hood cylinder body, a sliding groove and position limiting fixing holes are formed outside the protective hood cylinder body; a fixing insert slot is formed in the protective hood cylinder body; an anti-water wire hole and vents are formed on the cylinder body wall; a sun shield of the protective hood is arranged at the top part of the cylinder body, can achieve fore-and-aft movement and limiting fixing; the front cover of the protective hood is fixed at the front part of the cylinder part and adopts a design having characteristics of high intensity, high light transmission rate, water resistance, dust resistance, explosion-protection, optical filtering and heat insulation; the rear cover of the protective hood is fixed at the rear part of the cylinder body, adopts a design of high intensity, water resistance, explosion-protection and ventilation; the integrated supporting plate is arranged in the cylinder body and integrates a temperature control and heating module, a wiring terminal module, a camera fixing structure and an embedded system mainframe structure (including a mainframe casing, a functional integrated circuit board, an interface module and a ventilation structure). The protective hood adopts high intensity design, can achieve effective water resistance, explosion-protection, dust resistance and ventilation, lowers fault rates of the camera and the embedded system, and prolongs the service life of the camera.
