Abstract: An image surveillance device includes a casing, a lens module, a heater, a heat conduction sheet and a fan module. The lens module is disposed in the casing for capturing images. The heater is used for generating thermal energy. The heat conduction sheet is attached to the lens module and the heater for conducting the thermal energy to the lens module. The fan module is disposed on the heater for guiding airflow to cause heat convection in the casing. Accordingly, the present invention can solve the prior art problem that the thermal energy is accumulated on the heater, so as to greatly improve the thermal energy efficiency of the image surveillance device.

Abstract: The disclosure provides a light-enhancing component and a photographic device having the same. The light-enhancing component includes a light reflective unit and a light source. The light reflective unit includes a first reflecting surface and a second reflecting surface. The light source is disposed between the first reflecting surface and the second reflecting surface. An inclination of the first reflecting surface is different from an inclination of the second reflecting surface.

Abstract: The disclosure provides a photographing device which includes a main body, an image capturing module, a lighting module and a reflection module. The main body includes a substrate. The image capturing module is disposed on the main body. The lighting module is disposed on the substrate. The reflection module includes a cover movably disposed on the main body, for making the cover have a first position and a second position relative to the main body. The cover includes a first reflecting component and a second reflecting component. The first and the second reflecting components are adapted to make beams emitted from the lighting module form a first illumination and a second illumination field when the cover is located at the first position and the second position respectively. Accordingly, the lighting module has at least two illumination fields different from each other.
