Monitoring camera
A monitoring camera includes a plurality of camera units mounted in a circumferential direction of a device body, and a dome cover assembly including a dome cover collectively covering the plurality of camera units. The dome cover includes a water droplet guide surface continuous with an R surface and tilted downward as approaching an axis of the dome cover, and a water droplet receiving portion continuous with the water droplet guide surface. The camera unit includes a camera rotating a lens center axis on the virtual plane about a tilt rotation center in a direction perpendicular to the virtual plane. The water droplet receiving portion is provided outside of a field angle boundary of a field angle of the camera close to the axis in a state where the camera is tilted toward the axis side at a maximum tilt angle.
1. A monitoring camera comprising:
a plurality of camera units that are mounted in a circumferential direction of a device body attached substantially parallel to a ceiling surface; and
a dome cover assembly that includes a dome cover collectively covering the plurality of camera units and that is attached to the device body, wherein
the dome cover is formed, on a virtual plane including an axis of the dome cover and parallel to the axis, with a water droplet guide surface continuous with an R surface and tilted downward when approaching the axis, and a water droplet receiving portion continuous with the water droplet guide surface,
each of the plurality of camera units includes a camera that rotates a lens center axis on the virtual plane about a tilt rotation center in a direction perpendicular to the virtual plane, and
in a state where the camera is tilted toward the axis at a maximum tilt angle, the water droplet receiving portion is provided outside of a field angle boundary of a field angle of the camera close to the axis.
2. The monitoring camera according to claim 1 , wherein
the dome cover includes a circular recessed portion recessed in a direction approaching the ceiling surface and coaxially formed around the axis, and
the water droplet receiving portion is provided in an annular shape in a radially outer side of the circular recessed portion.
3. The monitoring camera according to claim 1 , wherein
the water droplet receiving portion is shared by the plurality of cameras.
4. The monitoring camera according to claim 1 , wherein
an included angle between the water droplet guide surface and a horizontal plane is in a range of 1° to 10°.
5. The monitoring camera according to claim 1 , wherein
a radial width of the water droplet receiving portion is 10 mm or more.
