a bracket including a first surface coupled to an inner surface of the aspherical part and a second surface extending a curved surface of an inner surface of the spherical part.
2. The dome of claim 1 , wherein a center of a sphere of the second surface is the same as a center of a sphere of the inner surface of the spherical part.
3. The dome of claim 2 , wherein a curvature of the second surface is equal to a curvature of the inner surface of the spherical part.
4. The dome of claim 1 , wherein a stepped portion between the inner surface of the spherical part and the second surface is less than or equal to 0.5 mm.
5. The dome of claim 1 , wherein the spherical part and the aspherical part are inscribed so as not to generate a boundary therebetween.
6. The dome of claim 1 , further comprising a cover reflection preventing part coupled with an outer circumferential surface of the aspherical part of the dome.
7. A surveillance camera comprising:
a camera module configured to capture an image of a surveillance area;
an infrared light source configured to illuminate the surveillance area with infrared light;
a dome configured to cover the camera module and the infrared light source and comprising:
a spherical part,
an aspherical part, and
a bracket including a first surface coupled to an inner surface of the aspherical part and a second surface extending a curved surface of an inner surface of the spherical part; and
an infrared hood coupled with the camera module to contact the inner surface of the spherical part or at least a portion of the second surface of the bracket.
8. The surveillance camera of claim 7 , wherein a curvature of the second surface of the bracket is equal to a curvature of the inner surface of the spherical part.
9. The surveillance camera of claim 8 , wherein the infrared hood contacts an inner surface of the dome within a tilt angle of the camera module.
10. The surveillance camera of claim 7 , wherein a stepped portion between the inner surface of the spherical part of the dome and the second surface of the bracket is less than or equal to 0.5 mm.
11. The surveillance camera of claim 7 , wherein the infrared hood surrounds a lens to spatially separate the lens from the infrared light source.
12. The surveillance camera of claim 7 , wherein the dome is formed such that the spherical part and the aspherical part are inscribed so as not to generate a boundary therebetween.
13. The surveillance camera of claim 7 , further comprising a cover reflection preventing part coupled with an outer circumferential surface of the aspherical part of the dome.
14. The surveillance camera of claim 7 , wherein a center of a sphere of the second surface is the same as a center of a sphere of the inner surface of the spherical part.
15. A surveillance camera comprising:
a camera module configured to capture an image of a surveillance area;
an infrared light source configured to illuminate the surveillance area with infrared light;
a dome comprising:
a spherical part having a hemispherical shape,
an aspherical part having a cylindrical shape extending from an end of the spherical part,
a bracket having a first surface coupled to an inner surface of the aspherical part and a second surface extending a curved surface of an inner surface of the spherical part while maintaining a curvature of the inner surface of the spherical part; and
an infrared hood coupled with the camera module to contact the inner surface of the spherical part or at least a portion of the second surface of the bracket,
wherein the infrared hood contacts an inner surface of the dome within a tilt angle of the camera module.
16. The surveillance camera of claim 15 , wherein the infrared hood surrounds a lens to spatially separate the lens from the infrared light source.
17. The surveillance camera of claim 15 , wherein a stepped portion between the inner surface of the spherical part and the second surface of the bracket is less than or equal to 0.5 mm.
18. The surveillance camera of claim 15 , wherein the dome is formed such that a boundary between the spherical part and the aspherical part is inscribed.
19. The surveillance camera of claim 15 , further comprising:
a base configured to support the camera module;
a case top configured to fix the dome to the base; and
a cover reflection preventing part coupled with an outer circumferential surface of the aspherical part of the dome.
20. The surveillance camera of claim 15 , wherein a center of a sphere of the second surface is the same as a center of a sphere of the inner surface of the spherical part.
