Surveillance camera
A surveillance camera is equipped with a capturing unit to capture a subject; an illumination unit that applies illumination light to the subject; a main body that is approximately formed in a cuboid that is long in a top-bottom direction and has an internal housing space that is partitioned by a partition plate into a lower space that houses the capturing unit and an upper space that houses the illumination unit; a visor that projects from a front surface of the main body so as to be inclined forward and covers a light-receiving space formed in front of the capturing unit; and a water repelling portion that is formed in step form in a tip portion of the visor.
1. A surveillance camera comprising:
a capturing unit that is configured to capture a subject;
an illumination unit that applies illumination light to the subject;
a main body that is approximately formed in a cuboid that is long in a top-bottom direction and has an internal housing space that houses the capturing unit and the illumination unit;
a visor that projects from a front surface of the main body so as to be inclined forward and covers, from above, a light-receiving space formed in front of the capturing unit; and
a step-shaped water repelling portion that is defined in a protrusion tip portion of the visor in such a manner that a tip inner circumferential surface of the visor recedes from a tip of an outer circumferential surface of the visor in a direction opposite to the projection of the visor.
2. A surveillance camera comprising:
a capturing unit that is configured to capture a subject;
an illumination unit that applies illumination light to the subject;
a main body that is approximately formed in a cuboid that is long in a top-bottom direction and has an internal housing space that houses the capturing unit and the illumination unit;
a visor that projects from a front surface of the main body so as to be inclined forward and covers, from above, a light-receiving space formed in front of the capturing unit; and
a step-shaped water repelling portion that is defined in a protrusion tip portion of the visor in such a manner that a tip inner circumferential surface of the visor recedes from a tip of an outer circumferential surface of the visor in a direction opposite to the projection of the visor, wherein
the water repelling portion has
a first tip surface that is connected to the tip outer circumferential surface,
a tip bottom surface that is connected to and bends inward from the first tip surface and
a second tip surface that is connected to the tip inner circumferential surface, and
the tip bottom surface and the second tip surface form an acute angle.
3. The surveillance camera according to claim 1 , wherein:
the visor is formed in an inverted-U-shaped gutter that is open at the bottom.
4. The surveillance camera according to claim 1 , wherein:
the visor has
a top protrusion tip portion and
a bottom protrusion tip portion that recedes from the top protrusion tip portion in the direction opposite to projection of the visor.
5. A surveillance camera comprising:
a capturing unit that is configured to capture a subject;
an illumination unit that applies illumination light to the subject;
a main body that is approximately formed in a cuboid that is long in a top-bottom direction and has an internal housing space that houses the capturing unit and the illumination unit;
a visor that projects from a front surface of the main body so as to be inclined forward and covers, from above, a light-receiving space formed in front of the capturing unit; and
a step-shaped water repelling portion that is defined in a protrusion tip portion of the visor in such a manner that a tip inner circumferential surface of the visor recedes from a tip of an outer circumferential surface of the visor in direction opposite to the projection of the visor, wherein
a glass plate which covers a lens of the capturing unit is disposed inside the visor so as to be inclined forward with respect to an imaginary line that is perpendicular to an optical axis of the lens.
6. The surveillance camera according to claim 5 , wherein:
a capturing unit opening where a bottom plate portion is provided is formed in a main body front portion of the main body; and
a bottom plate tip portion of the bottom plate portion is exposed as a result of forward inclination of the glass plate and retreat of a bottom portion of the glass plate, the bottom plate being formed with a cut right under an illuminance sensor provided under the glass plate.
7. A surveillance camera comprising:
a capturing unit that is configured to capture a subject;
an illumination unit that applies illumination light to the subject;
a main body that has an internal housing space that houses the capturing unit and the illumination unit;
a visor that projects from a front surface of the main body so as to be inclined forward and covers, from above, a light-receiving space formed in front of the capturing unit; and
a step-shaped water repelling portion that is defined in a protrusion tip portion of the visor in such a manner that a tip of an outer circumferential surface of the visor projects further outward from the main body than a tip inner circumferential surface of the visor.
8. A surveillance camera comprising:
a capturing unit that is configured to capture a subject;
an illumination unit that applies illumination light to the subject;
a main body that has an internal housing space that houses the capturing unit and the illumination unit;
a visor that projects from a front surface of the main body so as to be inclined forward and covers, from above, a light-receiving space formed in front of the capturing unit; and
a step-shaped water repelling portion that is defined in a protrusion tip portion of the visor and includes a groove disposed between an outer circumferential surface of the visor and a tip inner circumferential surface of the visor to prevent liquid accumulating on the visor from traveling to the inner circumferential surface and toward the main body.
