PURPOSE: A three-axial rotary holding unit for surveillance cameras is provided to enable three rotation bolts to control the rotation of a first arm, a second arm, and a supporting component and to combine each component together, thereby removing a separate rotation component and a separate combining unit. CONSTITUTION: A three-axial rotary holding unit for surveillance cameras includes a base(10), a first arm(20), a second arm(30), and a supporting component(40). Pinions(4a,4b,4c) rotated by rotation bolts(2a,2b,2c) are prepared on the base, the first arm, and the second arm. The pinion of the base is interlocked with a first large gear of the first arm. The pinion of the first arm is inserted and fixed to a teeth fixing part(32) of the second arm. The pinion of the second arm is interlocked with a second large gear of the supporting component.
