Abstract: Provided are an apparatus for supplying ink and an inkjet printing system including the same, and more particularly, to an apparatus for supplying ink, which may effectively circulate ink for inkjet printing to stably maintain a state of the ink, and an inkjet printing system including the same. The apparatus for supplying ink includes an ink storage unit configured to store ink at least temporarily, a first passage tube configured to supply the ink stored in the ink storage unit to an inkjet head unit, a second passage tube configured to collect the ink from the inkjet head unit, an ink circulation unit configured to move the ink introduced through the second passage tube in one direction, and a third passage tube configured to supply the ink discharged from the ink circuit unit to the ink storage unit.

Abstract: The present invention relates to a triaxial dome-type surveillance camera comprising: an upper cap (10) having a camera module (M) embedded therein; and a lower cap (20) coupled to a lower part of the upper cap (10), wherein the upper cap (10) and the lower cap (20) are seated on a triaxial rotary body (40) of the surveillance camera to be triaxially rotated, and a diffused reflection preventing device (13) is positioned on the upper cap (10), to which the camera module (M) is coupled, so as to prevent the diffused reflection of light, the diffused reflection degrading the quality of a photographed image.
