- the upper surface 58e of the second holder 57 is located lower than the upper surface 17c of the concave portion 17. Therefore, the upper surface 17c of the concave portion 17 functions as a roof of the cable holding mechanism 50, and can prevent direct exposure to wind and rain.
- the through hole 52 of the bottom surface 17a, the through hole 52 f of the cylindrical portion 52a of the first holder 52, and the opening on the inner peripheral side of the holding piece 57b of the second holder 57 are provided.
- the diameter of the connector is not limited to the above example as long as at least one of the connectors 18a and 18b of the power cable 18 can be connected.
- the cable holding mechanism used for the lead-out portion of the network cable 19 in the concave portion 17 has a through hole 51 on the bottom surface 17a and a through hole of the cylindrical portion 52a of the first holder 52.
- the diameter of the through hole 52 f and the opening on the inner peripheral side of the holding piece 57 b of the second holder 57 should be large enough to allow at least one connector of the network cable 19 to pass through. No.
- the surveillance camera 10 configured as described above has a ceiling 13 at one longitudinal end of a substantially rectangular main body 11 and a bottom 1 at the other end. 4 and the imaging unit 12 is provided in front of the main body 11 sandwiched between the ceiling 13 and the bottom 14, so that the imaging unit 12 can be installed along the outer wall 2. Since the surveillance camera 10 is installed outdoors, its outer casing is waterproof and hermetically sealed.However, as shown in Fig. 5, the power supply section 37 is built in the upper ceiling section 13, Since the control circuit section 29 is built in the main body section 11 below the power supply section 37, it is possible to prevent the control circuit section 29 from being damaged by the heat generated by the power supply section 37. it can.
- the support plate 31 is rotated in the direction of arrow D 2 in FIGS. 7 and 8 so as to be connected to the first rotation support plate 24 separated from the base 23, so that the overhanging piece 4 6 is provided.
- the first connector 18a of the power cable 18 attached to the jack of the power supply section 37 can be easily attached and detached without being disturbed by the power cable.
- the cable holding mechanism 50 pushes the rubber packing 55 by the pressing force Fa when the second holder 57 is tightened to the cylindrical portion 52 a of the first holder 52.
- the diameter of the through hole 55 a of the rubber packing 55 decreases in the direction of the arrow F b in FIG. 12, and the inner peripheral surface of the through hole 55 a extends outside the power cable 18. It is pressed against the peripheral surface, and the water tightness around the power cable 18 can be secured.
- the rubber packing 54 is attached. Watertightness can be ensured by being compressed in the groove 52e and pressed against the bottom 17a.
- the present invention is not limited to this example, and is applied to, for example, a portable digital or analog still camera or video camera. You can also.
