An imaging apparatus includes a housing having an opening, a camera unit including a lens and an imaging device, disposed inside the housing, and configured to image an external object through the opening, a telecommunication member disposed inside the housing and configured to connect a control substrate controlling the camera unit to an imaging device substrate on which at least the imaging device of the camera unit is mounted, and a communication antenna at least partially disposed in a gap between an inner edge of the opening and the camera unit as viewed in an optical axis direction of the camera unit at a position substantially symmetrical to the telecommunication member across the lens.

Imaging apparatus

An imaging apparatus includes a lens barrel unit, an image sensor substrate having an image sensor, a metal plate to which an image sensor substrate is fixed, a lens barrel holder made of a metal material and configured to support the lens barrel unit, a third cover member made of a heat-conductive resin material fixed to the lens barrel holder and configured to cover the circumferential surface of the lens barrel unit, and a heat-conductive member configured to conduct heat of an image sensor sheet metal to the lens barrel holder. At least a part of the lens barrel holder is disposed inside the third cover member.

Imaging apparatus capable of efficiently radiating heat of an image sensor without an increase in size

There is provided a monitoring camera including a first case that contains lens barrel unit and is rotationally movable between a first lock position and a first release position, and a second case that covers the lens barrel unit disposed in the first case and is rotationally movable between a second lock position and a second release position, wherein the second case can be removed from the first case in a state where the first case is fixed to an installation member by rotationally moving the second case to a first direction from the second lock position to the second release position in a state where the first case is located at the first lock position.

Imaging apparatus for use on a ceiling or wall surface

A composition for optical materials of the present invention includes a polyolefin (A) obtained by (co)polymerizing at least one kind of olefin selected from &#x3b1;-olefins having 3 to 20 carbon atoms and a photochromic compound (B).
