The present invention relates to an outside case of a surveillance camera for preventing foreign substance pollution, and more particularly to an outside case of a surveillance camera for preventing foreign substance pollution, in which a surveillance camera for photographing a subject is disposed in an internal space, and compressed air at a constant pressure is injected into the space through one side of the outside case and ejected through the other side thereof, thereby preventing foreign substances from being generated on the surveillance camera and a lens unit of the surveillance camera. The present invention is mainly focused on provision of an outside case of a surveillance camera for preventing foreign substance pollution, in which a surveillance camera for photographing is disposed in an internal space of the outside case, a through hole is formed in a front surface of the outside case, compressed air is injected into the space from a rear surface so that the compressed air can be ejected via the through hole in the front surface, and a partition, in which air holes are formed, and a partition, which prevents turbulence, are individually formed in front of the rear surface adapted to discharge the compressed air, thereby preventing foreign substances, such as dusts and minute particles, from being attached to the surveillance camera disposed inside the outside case. Accordingly, compressed air is ejected from the internal space of the outside case via the through hole formed on one side, and foreign substances are not generated inside the space of the outside case in which the surveillance camera is disposed. Furthermore, glass or a protection member is not required for the outside case, thereby improving sensitivity of the surveillance camera. Turbulence is preemptively prevented by the partition for turbulence prevention, thereby preventing foreign substances from being generated by turbulence. Accordingly, the outside case of a surveillance camera for preventing foreign substance pollution can be semi-permanently employed in a paint factory or a painting factory in which a relatively large quantity of foreign substances are generated, or at a location at which fine dusts are generated. |
