Description

Technical Field

[0001] The present invention relates to a waterproof cover for a camera that can be used for a camera installed outdoors for monitoring outdoor equipment and the like.

Background Art

[0002] For example, when using a network camera used indoors for monitoring outdoor equipment outdoors, a LAN cable is connected to the camera, and the camera is fixed to the upper part of a tripod and installed at a desired location. However, when such an indoor camera is diverted as a monitoring camera outdoors, it is necessary to take sufficient waterproof measures against rain and the like. For this reason, conventionally, each time camera A was installed, a plastic bag was put on it, and the LAN cable was pulled out from the opening part below the plastic bag.

[0003] Also, conventionally, as a waterproof cover for a camera, there is known one that houses a holder for housing the camera in a bag body (see Patent Document 1), or one that is composed of a front cover that covers the front part of the camera and a rear cover that covers the rear part of the camera, which is formed so as to substantially follow the outer shape of the camera (see Patent Document 2), and the like.

Summary of the Invention

Problems to be Solved by the Invention

[0005] However, when performing waterproof curing with a plastic bag, the curing methods vary, the work is inefficient, and the image becomes unclear. Also, when checking the camera in the event of video abnormalities or the like, it was necessary to redo the curing each time. In this regard, in the conventional waterproof cover for cameras described above, a predetermined waterproof function is obtained and the blurriness of the image is eliminated. However, since it is formed according to the shape of the camera, the camera is not installed in the cover with a margin. For this reason, it is impossible to cope with cameras having different shapes, and it has no versatility. Further, when installed outdoors, it may be hit by foreign objects or exposed to wind and rain for a long time. Conventionally, since such a state is not assumed, if the case is deformed when hit by a foreign object, the structural damage will directly affect the camera, and there is a possibility that water may seep in from a position higher than the installation position of the camera, so the waterproof function cannot be sufficiently guaranteed. Furthermore, outdoors, there are also inconveniences such as lens flare caused by sunlight and an increase in the temperature inside the cover. For this reason, it was not suitable in terms of strength or structure for adapting the conventional waterproof cover for cameras to cameras installed outdoors.

[0006] The present invention has been made in view of such circumstances, and a main object thereof is to provide a waterproof cover for cameras that can accommodate various cameras, can reliably protect the camera from foreign object collisions and rain even when installed outdoors for a long time, and can also suppress the influence of sunlight.

Means for Solving the Problems

[0007] In order to achieve the above object, a waterproof cover for cameras according to the present invention is a waterproof cover for cameras that detachably attaches to a camera support and covers the camera. It includes an upper lid with an open bottom that covers the camera from above, and a bottom plate attached so as to close the lower surface of the upper lid. The upper lid has an upper wall portion extending from the front surface to the rear surface, a pair of side wall portions integrally formed with the upper wall portion and hanging down from both side edges of the upper wall portion, and a pair of end wall portions hermetically joined to the upper wall portion and the side wall portions and capable of facing the front and rear surfaces of the camera. The bottom plate is fixed between the camera and the camera support and is fixed to the upper lid by fixing means. The upper wall portion and the pair of side wall portions of the upper lid are made of a translucent or opaque resin material, and the pair of terminal wall portions are made of a transparent resin material. The upper wall portion and the side wall portions of the upper lid project beyond the terminal wall portions at least on the front side. On the upper surface of the bottom plate, a pair of guide plates are erected at a predetermined interval to define the installation state of the camera, direct the front surface of the camera toward the front surface of the upper lid, and direct the rear surface of the camera toward the rear surface of the upper lid. along the upper surface of the bottom plate and extending back and forth erected with a predetermined interval therebetween. parallel It is characterized in that.

[0008] Therefore, the camera is fixed to the camera support while being placed on the bottom plate, and is housed in the case in a state of being covered with an upper lid made of a hard resin material having a rectangular cross-section with an open lower surface. The upper lid is not formed along the shape of the camera, and a space is formed between the upper lid and the camera. Thus, the camera is housed with a margin in the waterproof cover. For this reason, even if a foreign object hits the upper lid, it is possible to avoid the damage from affecting the camera. Further, the upper lid is composed of an upper wall portion, a pair of side wall portions integrally provided therewith, and a pair of terminal wall portions on the front side and the rear side hermetically joined to the upper wall portion and the side wall portions. The boundary with the bottom plate on which the camera is installed is also at or below the lower end of the camera. Therefore, it is possible to surely prevent wind and rain. Even if rainwater seeps in from the boundary between the upper lid and the bottom plate, the camera will not be splashed with rainwater.

[0009] Furthermore, since the upper wall portion and the pair of side wall portions of the upper lid are made of a translucent or opaque resin material, it is possible to prevent direct sunlight, and it is possible to reduce the deterioration of the camera due to ultraviolet rays and the temperature rise inside the camera and the cover. Also, since the pair of terminal wall portions are made of a transparent resin material, the image will not become unclear, and the operating state of the camera and the error display lamp will not be difficult to see.

[0010] In addition, since the upper wall portion and the side wall portion of the upper lid project beyond the terminal wall portion at least on the front side, it is easier to block backlight, and it is also possible to reduce the rainwater hitting the terminal wall portion facing the camera lens during rainy days or the like. Note that the upper wall portion and the side wall portion of the upper lid may project beyond the terminal wall portion on each of the front side and the rear side. With such a configuration, in addition to the above-described effects, it is also possible to suppress the adhesion of rainwater to the terminal wall portion on the rear end side of the camera, and it is possible to avoid the inconvenience that the operating state of the camera and the error display lamp are difficult to see. Moreover, since it is possible to make the waterproof cover symmetric in shape, there is no need to worry about the front and rear in the installation work of the waterproof cover.

[0011] In the above-described configuration, only the lower surface of the upper lid is open, and the lower surface of the upper lid is closed by the bottom plate on which the camera is installed. Therefore, the boundary between the upper lid and the bottom plate does not come above the camera, and an effective waterproof effect is obtained. However, in order to obtain a more reliable waterproof function, it is advisable to interpose a sealing material between the upper lid and the bottom plate.

[0012] In addition, since the camera is installed in the waterproof cover with a margin, there may occur an inconvenience that the orientation of the camera accommodated in the waterproof cover is not fixed in a predetermined orientation. Furthermore, On the upper surface of the bottom plate, since a pair of guide plates are provided to define the installation state of the camera such that the front surface of the camera faces the front surface of the upper cover and the rear surface of the camera faces the rear surface of the upper cover, it is possible to always keep the installation state (orientation) of the camera in the cover constant.

Effect of the Invention

[0013] As described above, according to the present invention, there are provided an upper lid whose lower surface is open and covers the camera from above, and a bottom plate attached so as to close the lower surface of the upper lid. The upper lid is configured to have an upper wall portion, a pair of side wall portions integral therewith, and a pair of end wall portions hermetically joined to the upper wall portion and the side wall portions. The upper lid is fixed to the bottom plate fixed between the camera and the camera support by fixing means. The upper wall portion and the pair of side wall portions of the upper lid are made of a translucent or opaque rigid resin material, and the pair of end wall portions are made of a transparent rigid resin material. Further, the upper wall portion and the side wall portions of the upper lid project more than the end wall portions at least on the front side. Also, on the upper surface of the bottom plate, the installation state of the camera is defined so that the front surface of the camera faces the front surface of the upper lid and the rear surface of the camera faces the rear surface of the upper lid. along the upper surface of the bottom plate and extending back and forth A pair of guide plates are provided at a predetermined interval. parallel and are erected, so (1) Since the camera can be accommodated in the waterproof cover with a margin, even if a foreign object collides with the cover, damage to the camera can be suppressed. (2) By using an upper lid with only the lower surface open and closing the lower surface of the upper lid with a bottom plate on which the camera is installed, the boundary between the upper lid and the bottom plate does not come above the camera, and an effective waterproof effect can be obtained. (3) Since the upper wall and the pair of side wall portions of the upper lid are made of a translucent or opaque resin material, the inconvenience of direct sunlight hitting the camera (deterioration of the camera by ultraviolet rays and temperature rise inside the camera and the cover) can be reduced. (4) Since the pair of end wall portions are made of a transparent resin material, the image will not become unclear, and the operating state of the camera and the error display lamp can be easily seen. (5) Since the upper wall portion and the side wall portions of the upper lid project more than the end wall portions at least on the front side, it becomes easier to block backlight, and it is possible to reduce the inconvenience of rainwater adhering to the end wall portions during rainy days and the like. 、 (6) since a pair of guide plates extending back and forth along the upper surface of the bottom plate are vertically installed in parallel with a predetermined interval therebetween, it becomes possible to install the camera with its front surface facing the front surface of the upper cover and its rear surface facing the rear surface, The installation state (orientation) of the camera is always kept constant. and it can be maintained.

MODE FOR CARRYING OUT THE INVENTION

[0015] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

[0016] The waterproof cover 1 for a camera is used when installing an indoor-specification camera, for example, a network camera A (hereinafter referred to as the camera) that does not require a power cable and is only connected to a LAN cable outdoors. As shown in FIG. 1, it is fixed to the pan head C of the tripod B and prevents the camera A housed and fixed inside from being affected by wind, rain, and collisions with foreign objects.

[0017] This waterproof cover 1 for a camera is entirely formed of synthetic resin and is composed of an upper cover 2 with an open bottom surface and a bottom plate 3 attached to close the open portion of the upper cover 2, as also shown in FIGS. 2 to 4.

[0018] The upper cover 2 has a cover body 21 with a U-shaped cross section formed by integrating a flat upper wall portion 21a and a pair of side wall portions 21b and 21c bent approximately 90 degrees downward from both side edges of the upper wall portion 21a, and a pair of end wall portions 22 and 23 hermetically joined to the upper wall portion 21a and the side wall portions 21b and 21c by an adhesive or the like and capable of facing the front and rear surfaces of the housed camera.

[0019] The cover body 21 is formed of a translucent or opaque acrylic plate (for example, gray) to prevent direct sunlight, ensure strength, and achieve weight reduction. It extends along an axis parallel to the upper wall portion 21a and the side wall portions 21b and 21c of the cover body 21, with one end side in the axial direction being the front side and the other end side being the rear side.

[0020] On the other hand, the end wall portions 22 and 23 are processed into a shape that matches the cross-sectional shape surrounded by the cover body 21 from a transparent acrylic plate and are fixed to the front side and the rear side of the cover body 21. These end wall portions are provided substantially perpendicular to the upper wall portion 21a and the side wall portions 21b and 21c (substantially perpendicular to the axis that is horizontal with respect to the upper wall portion and the side wall portions), and are attached in accordance with the positions of the front end and the rear end of the lower edge of the side wall portions 21b and 21c.

[0021] In this example, the side wall portions 21b and 21c of the cover body 21 are formed such that the upper edge is longer than the lower edge. On the rear side, the rear end of the upper edge and the rear end of the lower edge are at the same position as the terminal wall portion 23. However, on the front side, the front end of the upper edge protrudes forward more than the front end of the lower edge. Therefore, the terminal wall portion 23 on the rear side is erected so as to coincide with the rear end of the cover body 21, while the terminal wall portion 22 on the front side is erected at a position in front of the front end of the upper wall portion 21a of the cover body 21, and the cover body 21 projects forward from the terminal wall portion 22 more as it goes upward. The upper cover 2 formed in this way is sized to accommodate network cameras of various shapes, and in a state where the camera A is accommodated, the camera A does not come into contact with the inner surface of the upper cover.

[0022] The bottom plate 3 is formed of a semi-transparent or opaque acrylic plate (for example, gray) in order to prevent direct sunlight, ensure strength, and achieve weight reduction. Also, the lateral width is formed to a dimension that can simultaneously place the pair of side wall portions 21b and 21c, and the axial length is formed to a dimension that substantially matches the length of the lower sides of the side wall portions 21b and 21c. Therefore, when the bottom plate 3 is assembled to the upper cover 2 from below, the pair of front and rear terminal wall portions 22 and 23 are placed on the front edge and the rear edge of the bottom plate 3, and the entire opening portion of the upper cover 2 is closed.

[0023] Also, on the upper surface of the bottom plate 3, standing pieces 31 and 32 erected along the inner surfaces of the side wall portions 21b and 21c of the pair of cover bodies 21 are integrally formed. The pair of standing pieces 31 and 32 are formed to a predetermined length along the side wall portions 21b and 21c, and the surfaces facing the side wall portions 21b and 21c of the upper cover 2 are in sliding contact with the inner surfaces of the side wall portions 21b and 21c or have a slight clearance. Then, screw holes 33 are formed in the standing pieces 31 and 32 at a predetermined interval, and through holes 25 for inserting fixing screws 24 are formed in the side wall portions 21b and 21c facing these at positions that match the screw holes 33.

[0024] Furthermore, near the center of the bottom plate 3, there are provided a through hole 34 for inserting the camera mounting screw of the tripod head and a through hole 35 for passing the LAN cable connected to the camera.

[0025] In the above configuration, to attach the waterproof cover 1 for the camera, pass the LAN cable D from below through one of the through holes 35 from below the bottom plate 3 and connect this LAN cable D to the camera A (or pass the LAN cable D connected to the camera A from above). Also, insert the camera mounting screw E of the head C of the tripod B through the other through hole 34 from below the bottom plate 3 and thread it into the screw hole of the camera A, while adjusting the orientation of the camera A on the bottom plate 3 (adjusting so that the front of the camera A faces the front of the upper cover 2 and can face the terminal wall portion 22, and also adjusting so that the rear of the camera A faces the rear of the upper cover 2 and can face the terminal wall portion 23), sandwich and fix the bottom plate 3 between the camera A and the head C.

[0026] After that, cover the upper cover 2 over the camera A from above the bottom plate 3, place the upper cover 2 on the bottom plate 3 so as to block the entire opening portion of the upper cover 2 with the bottom plate 3, and align the through holes 25 of the side wall portions 21b, 21c with the screw holes 33 of the standing pieces 31, 32. Then, insert the fixing screw 24 into the through hole 25 from the outside of the upper cover 2 and screw it into the screw holes 33 of the standing pieces 31, 32 to firmly fix the upper cover 2 to the bottom plate 3.

[0027] As a result, the camera A is fixed to the tripod B in a state of being entirely covered by the waterproof cover 1 for the camera, and is stored in a state where a space is secured between it and the upper cover 2. At this time, the upper cover 2 is closed in the front, rear, left, right, and upward directions by the cover body 21 and the terminal wall portions 22, 23 that are airtightly joined to it, and the boundary with the bottom plate 3 can be set at the position of the lower end of the camera A. Therefore, even if it is left outdoors for a long time, the camera will not be exposed to wind and rain, and even if rainwater infiltrates from the boundary between the upper cover 2 and the bottom plate 3, it will not reach the camera A. Moreover, since the camera A is installed in the cover without contacting the upper cover 2, even if a foreign object collides with the upper cover 2 and the upper cover is damaged, it is possible to suppress damage to the camera.

[0028] In addition, since the upper wall portion 21a, the pair of side wall portions 21b and 21c of the upper lid 2, and the bottom plate 3 are made of a translucent or opaque resin material, it is possible to avoid the inconvenience of direct sunlight hitting the camera. Even if it is left outdoors for a long time, it is possible to reduce the deterioration of the camera due to ultraviolet rays and the temperature rise inside the camera and the cover.

[0029] Furthermore, since the pair of terminal wall portions 22 and 23 are made of a transparent resin material, it is possible to avoid inconveniences such as the lack of image clarity and the difficulty in seeing the operating state of the camera and the error display lamp.

[0030] Furthermore, on the front side, the upper wall portion 21a and the side wall portions 21b and 21c of the upper lid 2 are made to protrude more than the terminal wall portion 22, so it becomes easier to block backlight, and also, in rainy weather, it is possible to avoid inconveniences such as rainwater adhering to the terminal wall portion 22 and making it difficult to see.

[0031] Also, in the above-described configuration, since the standing pieces 31 and 32 are standing on the bottom plate 3 along the side wall portions 21b and 21c, it is possible to prevent rainwater from reaching the camera A even if rainwater infiltrates through the gap between the upper lid 2 and the bottom plate 3. In order to more surely prevent rainwater from reaching the camera A, standing pieces may be provided along the entire circumference of the periphery of the bottom plate 3 (standing pieces may also be provided along the terminal wall portions 22 and 23). By doing so, a more reliable waterproof function can be obtained without providing a sealing member between the upper lid 2 and the bottom plate 3.

[0032] In the above configuration, since the upper lid 2 covers the front, rear, left, right, and upper sides, a waterproof function with no practical problems can be obtained. However, if it is desired to further enhance the sealing performance between the upper lid 2 and the bottom plate 3, and also in the above example, it is necessary to attach the upper lid 2 so as not to misalign the front and rear. However, if it is desired to perform the attachment work of the cover without worrying about the front and rear, and furthermore, if rainwater adheres to the terminal wall portion 23 on the rear side, it becomes difficult to see the operating state of the camera, the error display lamp, etc., and if it is desired to eliminate this, and furthermore, in the installation of the camera on the bottom plate 3, if it is desired to eliminate the need for adjusting the installation state (orientation) of the camera A, it is advisable to use the waterproof cover for the camera shown in FIGS. 5 to 7.

[0033] Hereinafter, a second configuration example of the waterproof cover for the camera shown in FIGS. 5 to 7 will be described. This waterproof cover for the camera is also entirely formed of a synthetic resin material such as acrylic, and is composed of an upper lid 2 with an open lower surface and a bottom plate 3 attached so as to close the open portion of the upper lid 2.

[0034] The upper lid 2 includes a flat upper wall portion 21a, a pair of side wall portions 21b and 21c bent at approximately 90 degrees and hanging down from both side edges of the upper wall portion 21a, and a lower wall portion 21d spanning the lower end edges of the pair of side wall portions 21b and 21c, and is integrated into a cover body 21 having a substantially rectangular cross-section. The upper wall portion 21a, the pair of side wall portions 21b and 21c, and the lower wall portion 21d of the cover body 21 are hermetically joined by an adhesive or the like and are configured to have a pair of terminal wall portions 22 and 23 that can face the front and rear surfaces of the accommodated camera.

[0035] The upper wall portion 21a of the cover body 2 is formed to have a length corresponding to the lengths of the upper end edges of the pair of 21b and 21c, and the lower wall portion 21d is formed to have a length corresponding to the lengths of the lower end edges of the pair of side wall portions 21b and 21c. Further, an opening 26 is formed in the middle of the lower wall portion 21d, and a locking margin 27 of a predetermined width is formed on the periphery of the opening. And screw holes 28 are formed in the locking margin 27 at predetermined intervals.

[0036] This cover body 21 is formed of a translucent or opaque acrylic plate (e.g., gray) in order to prevent direct sunlight, ensure strength, and achieve weight reduction. It extends along an axis parallel to the upper wall portion 21a, side wall portions 21b and 21c, and lower wall portion 21d of the cover body 21, with one end side in the axial direction being the front side and the other end side being the rear side.

[0037] On the other hand, the end wall portions 22 and 23 are processed into a shape that conforms to the cross-sectional shape surrounded by the cover body 21 with a transparent acrylic plate, and are fixed to the front side and rear side of the cover body 21. These end wall portions 22 and 23 are provided substantially perpendicular to the upper wall portion 21a, side wall portions 21b, 21c, and lower wall portion 21d (substantially perpendicular to the axis that is horizontal with respect to the upper wall portion, side wall portions, and lower wall portion), and are attached in accordance with the positions of the front end and rear end of the lower edge of the side wall portions 21b and 21c.

[0038] In this example, the side wall portions 21b and 21c of the cover body 21 are formed such that the upper edge is longer than the lower edge. In this example, the side wall portions 21b and 21c of the cover body 21 protrude forward at the front end of the upper edge portion more than the front end of the lower edge portion on the front side, and the rear end of the upper edge portion protrudes rearward more than the rear end of the lower edge portion on the rear side. Therefore, the front end wall portion 22 on the front side is erected at a position in front of the front end of the upper wall portion 21a of the cover body 21, and the rear end wall portion 23 on the rear side is erected at a position in front of the rear end of the upper wall portion 21a of the cover body 21. The cover body 21 protrudes forward from the end wall portion 22 and rearward from the end wall portion 23 more as it goes upward. Therefore, the upper lid 2 has a shape that is contrastive in the front and rear directions and can be used with either the front or rear direction in the axial direction as the front side. The upper lid 2 formed in this way is formed in a size that can accommodate various-shaped network cameras, and in a state where the camera A is accommodated, the camera A does not come into contact with the inner surface of the upper lid.

[0039] The bottom plate 3 is made of a translucent or opaque acrylic plate (e.g., gray) in order to prevent direct sunlight, ensure strength, and achieve weight reduction. Also, it is formed with dimensions such that the lateral width and the axial length match those of the lower wall portion 21d. In the middle, a pair of guide plates 36 for defining the installation state (orientation) of the camera installed thereon are erected at a predetermined interval. This pair of guide plates 36 is formed at a position and size that do not interfere with the locking margin 27 at the opening periphery of the lower wall portion 21d, and functions as an auxiliary member for accurately orienting the camera placed on the bottom plate 3 in the axial direction of the upper lid 2. Further, through holes 37 are formed at positions on the periphery of the bottom plate 3 that are aligned with the screw holes 28 where the locking margin 27 of the lower wall portion 21d is formed.

[0040] Therefore, when the bottom plate 3 is assembled to the upper lid 2 from below, the periphery of the bottom plate 3 overlaps with the locking margin 27 of the lower wall portion 21d of the upper lid 2 (cover body 21), and a pair of guide plates 36 provided on the bottom plate 3 protrude from the opening 26 of the lower wall portion 21d into the inside of the upper lid 2. Also, a sealing member 4 for hermetically sealing the space between the lower wall portion 21d of the upper lid 2 and the bottom plate 3 is provided therebetween. This sealing member 4 is formed in a size corresponding to that of the lower wall portion 21d, has an opening 41 corresponding to the opening 26 of the lower wall portion 21d, and is formed in the same shape as the locking margin 27 of the lower wall portion 21d. Through holes 42 are also formed in this sealing member 4 at positions aligned with the screw holes 28 of the lower wall portion 21d.

[0041] Therefore, when the bottom plate 3 is assembled to the lower wall portion 21d via the sealing member 4 and the fixing screw 24 inserted through the through holes 37 and 42 is screwed into the screw hole 28 of the upper lid 2 to fasten the bottom plate 3 to the lower wall portion 21d of the upper lid 2, the entire space between the locking margin 27 of the lower wall portion 21d and the bottom plate 3 is hermetically sealed by the sealing member 4. Note that since other configurations are the same as those in the above-described configuration example, the same reference numerals are given to the same parts and the description thereof is omitted.

[0042] In the above configuration, to attach the waterproof cover 1 for the camera to the tripod B, pass the LAN cable D through one of the through holes 35 from below the bottom plate 3 and connect this LAN cable D to the camera A (or pass the LAN cable D connected to the camera A from above). Also, insert the camera mounting screw E of the pan / tilt head C of the tripod B through the other through hole 34 from below the bottom plate 3 and thread it into the screw hole of the camera A. At this time, since a pair of guide plates 36 are provided on the bottom plate 3, if the camera A is placed between this pair of guide plates 36 or on the upper part of the pair of guide plates 36, the front of the camera A can be oriented towards the front of the upper cover 2 (so as to face the terminal wall portion 22 on the front side), and the rear of the camera A can be oriented towards the rear of the upper cover 2 (so as to face the terminal wall portion 23 on the rear side). Thus, it becomes possible to sandwich and fix the bottom plate 3 between the camera A and the pan / tilt head B in a state where the installation state (orientation) of the camera on the bottom plate is defined.

[0043] After that, place the seal member 4 on the bottom plate 3, cover the camera A with the upper cover 2 from above, align the through hole 42 of the seal member 4 and the through hole 37 of the bottom plate 3 with the screw hole 28 of the upper cover 2, insert the fixing screw 24 from the outside of the bottom plate 3 into the through holes 37 and 42, and screw it into the screw hole 28 of the upper cover 2 to fix the upper cover 2 and the bottom plate 3 via the seal member 4. At this time, by tightening the fixing screw 24 strongly, the space between the upper cover 2 and the bottom plate 3 is firmly sealed by the seal member 4.

[0044] As a result, the camera A is fixed to the tripod B in a state where the whole is hermetically covered by the waterproof cover 1 for the camera, and is stored in a state where a space is secured between it and the upper cover 2. At this time, the upper cover 2 is closed at the front, rear, left, right, and above by the cover body 21 and the terminal wall portions 22 and 23 that are hermetically joined to it. The boundary with the bottom plate 3 can be set below the lower end of the camera A, and since the boundary with the bottom plate 3 is sealed by the seal member 4, it is possible to surely prevent rainwater from entering. Also, since the camera A is installed in the cover in a state where it does not contact the upper cover 2, even if a foreign object collides with the upper cover 2 and the upper cover is damaged, it is possible to suppress damage to the camera.

[0045] In addition, since the upper wall portion 21a, the pair of side wall portions 21b and 21c of the upper lid 2, and the bottom plate 3 are made of a translucent or opaque resin material, it is possible to avoid the inconvenience of direct sunlight hitting the camera, and even if it is left outdoors for a long time, it is possible to reduce the deterioration of the camera due to ultraviolet rays and the temperature rise inside the camera and the cover.

[0046] Furthermore, since the pair of terminal wall portions 22 and 23 are made of a transparent resin material, it is possible to avoid inconveniences such as the image becoming unclear and the operating state of the camera and the error display lamp becoming difficult to see.

[0047] Furthermore, on the front side and the rear side, the upper wall portion 21a and the side wall portions 21b and 21c of the upper lid 2 are made to project more than the terminal wall portions 22 and 23, so that it becomes easier to block backlight on the front side, and also, in rainy weather, it is possible to avoid inconveniences such as raindrops adhering to the terminal wall portions 22 and 23 and becoming difficult to see.

[0048] In addition, since the upper lid 2 has an axially symmetric shape, either side can be used as the front, and there is no need to worry about the direction of attaching the upper lid 2, making it easier to attach the waterproof cover for the camera.
