In this case, in the surveillance camera device 1, since the camera sensitivity can be changed by changing the light transmittance of the filter cover 12, the light transmittance of the filter cover 12 is selected. Thus, a desired camera sensitivity can be obtained.

Further, in the above-mentioned embodiment, the case where the two signal cable connecting portions 5A and 5B are provided on the upper surface 2B of the housing 2 has been described, but the present invention is not limited to this, and the signal cable connecting end is not limited to this. You may make it provide 3 or more 5A, 5B. In this case, each signal cable connection end 5
By making the connection directions of the signal cables for A and B different from each other, wiring can be performed more efficiently.

As described above, according to the first aspect of the invention, inside the housing formed in the shape of a hollow triangular pyramid, the image is spread in the front direction of the imaging surface through the imaging surface which is the bottom surface of the housing. The housing 2 itself can be miniaturized by accommodating the imaging means for imaging the scene of the space and by disposing the circuit board along the inner surface of the side surface of the housing connected to the imaging surface. Thus, it can be made inconspicuous when installed. Therefore, it is possible to realize an image pickup apparatus capable of performing soft monitoring without noticing that it is being monitored.

According to the second aspect of the present invention, the view of the space spreading in the front direction of the image pickup surface, which is the bottom surface of the housing, is provided by the image pickup means housed in the hollow triangular pyramid shaped housing. By taking an image through the semitransparent filter means forming part or all of the imaging surface of the housing, the lens of the imaging means can be made difficult to see from the outside of the housing, and thus the lens can be It is possible to prevent the interior quality from being deteriorated by being visible from the outside and reduce the presence. Therefore, it is possible to realize an image pickup apparatus capable of performing soft monitoring without noticing that it is being monitored.

Further, according to the third aspect of the invention, the housing is formed in a hollow triangular pyramid shape, and a plurality of signals having different connection directions of signal cables as signal transmission paths are provided on a predetermined outer surface of the housing. By providing the output terminals 5A and 5B,
It can be installed in an inconspicuous position without worrying about the wiring. Therefore, it is possible to realize an image pickup apparatus capable of performing soft monitoring without noticing that it is being monitored.

Further, according to the fourth aspect of the present invention, the image of the space spreading in the front direction of the image pickup surface which is the bottom surface of the casing is provided by the image pickup means housed in the hollow triangular pyramid shaped casing.
An image is taken through a semitransparent filter means that forms a part or all of the image pickup surface of the housing, and the light that enters and exits inside the housing other than the lens of the image pickup means is blocked through the filter means. By doing so, it is possible to prevent the interior quality from being deteriorated due to the inside of the housing other than the lens being seen from the outside, and to reduce the presence. Therefore, it is possible to realize an image pickup apparatus capable of performing soft monitoring without noticing that it is being monitored.
