DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0015] Generally, surveillance cameras can be broadly divided into two types depending on how they are installed. One type is a surveillance camera that does not hide its presence, but rather deliberately makes the subjects of surveillance aware of its presence, with the aim of deterring illegal or nuisance behavior. The other is a surveillance camera that makes its presence as unnoticeable as possible. The present embodiment is a surveillance camera of the latter type (a type that is as unrecognizable as a surveillance camera as possible) (hereinafter referred to as a "secret surveillance camera").

[0016] In addition, such hidden cameras are not only installed at the time of various constructions or installations, but may also need to be installed later. Additionally, there may be a need to install the device for a limited period of time rather than permanently. It is also appropriate for the installation work to be as simple as possible, because if the installation takes time or requires major construction (such as wiring work), confidentiality will be compromised. The surveillance camera of the present invention is suitable for such applications.

[0017] <First embodiment> Hereinafter, an embodiment of the present invention will be described in detail.

[0018] FIG. 1 is an explanatory diagram of the structure of a surveillance camera 1 according to a first embodiment and a method of mounting the surveillance camera on a pole 101. As shown in FIG.

[0019] As shown in FIG. 1, the surveillance camera 1 has a first portion 51 and a second portion 11. The first portion 51 is inserted into the cylindrical pole 101 . The pole 101 may be, for example, a pole for various signs (speed signs, no parking signs, and other signs), a guardrail pole, or a pole used for other fences, etc. In many cases, these poles 101 are already installed, and the surveillance camera 1 of this embodiment can be attached to them as is. In addition, these poles 101 are often not supplied with electricity nearby, and even if there is a power source nearby, the construction work itself would be conspicuous. Therefore, the battery 52 described below becomes extremely important. On the other hand, the second portion 11 does not enter the pole 101 and looks as if it were an upper cover. Since this second portion is exposed to the outside, it is appropriate that it is as inconspicuous as possible. Therefore, it is preferable that the cover has at least the same shape or color as the cover used for that type of pole 101 (resembling the cover provided on the top of the pole 101), because this increases secrecy. Incidentally, this lid is often provided for safety reasons to prevent rainwater, garbage, insects, etc. from entering the inside of the pole 101 (if the top of the pole 101 is exposed, there is a risk of injury to people).

[0020] The first portion 51 holds at least the battery 52 therein. It will now be described that it is appropriate for the battery 52 to be contained in this position. Surveillance cameras for the applications mentioned above (the need to be retrofitted, the need to be removed, the need for confidentiality) are often installed in places without a power source, and even if there is a power source nearby, if construction work is required the construction itself will compromise confidentiality, and they must be able to be used for long periods of time once installed, among other restrictions.

[0021] In such a case, it is necessary to enable long-term operation by installing a large-capacity battery 52. ​​And the large-capacity battery 52 naturally needs to have a large volume in proportion to the large capacity. On the other hand, as described above, since it is generally preferable to make the second portion 11 small for the sake of concealment, it is difficult to load most, if not all, of the large battery 52 in this portion. In addition, since the first portion 51 is stored in the internal space of the pole 101, even if it is somewhat large, it does not affect secrecy. Therefore, it is desirable that most of the battery 52 be housed (mounted) in the first portion 51.

[0022] The second portion 11 has a cylindrical shape. The first portion 51 also has a cylindrical shape with a smaller diameter than the second portion 11 . The first portion 51 is connected to the lower side of the second portion 11 with the respective cylinders being coaxially aligned. As shown in FIG. 1, the second portion 11 has a ceiling portion 11a, a side portion 11b, and a bottom portion 11c. Here, the bottom surface portion 11c has a circular shape with a hollowed-out center. This bottom surface portion 11c has the role of coming into contact with the upper end of the pole 101 when the surveillance camera 1 is inserted into the pole 101.

[0023] The ceiling portion 11a is circular. It is also possible to install a solar panel or the like on this portion. In this case, the capacity of the battery 52 can be reduced, or the usable time of the battery 52 can be extended.

[0024] A movable portion 11d is provided near the center of the side surface portion 11b. A camera unit 21 and a sound collecting unit 41 are installed on the movable unit 11d. Although the sound collection unit 41 is not essential, it is preferable to have the sound collection unit 41 since there are cases where sound is required for the surveillance camera 1. It is preferable that the movable part 11d can be driven left and right by a mechanism such as a gear, etc. This is to move it in the direction of a monitoring target (a sound collection target) as necessary. The movable portion 11d may rotate 360 ​​degrees, or may rotate less than that, for example, 180 degrees or 90 degrees. It is preferable that there is a cover or the like on the outside of the movable portion 11d, and the movable portion 11d moves inside the cover. This is because the movement of the camera unit 21, etc. cannot be easily recognized from the outside. It is preferable that the camera unit 21 has not only focusing functions but also zooming in and out functions (optical zooming by moving the lens and / or electronic zooming) because there is a demand for magnifying only the monitored area. Furthermore, the pole 101 is often located at a high position, and in such a case, it is preferable that the camera unit 21 is angled downward. Furthermore, the camera unit 21 may be able to change its angle in the vertical direction to a certain extent. This is particularly preferable when capturing an image of a monitoring target from a high position.

[0025] An antenna portion 31a is provided on the second portion 11. This is because, since the pole 101 is usually made of metal, providing the antenna portion 31a on the first portion 51 makes appropriate communication difficult. The antenna unit 31a has a communication unit 31. The communication unit 31 does not necessarily have to be in the second portion 11. The communication unit 31 may also include, for example, a SIM card for a mobile communication network.

[0026] It is preferable to use, for example, rubber between the bottom surface 11c and the top surface 101a of the pole to prevent rainwater or the like from entering the pole 101. Moreover, it is more preferable that the surveillance camera 1 has a fixed structure so that it cannot be moved, carried away, or dropped off. For example, it is more preferable that the first portion 51 has a structure that expands to bring the first portion 51 into close contact with the pole inner circumference 101b of the pole 101. Alternatively, a screw or the like may expand and the head of the screw may come into contact with the inner circumference of the pole 101 to generate friction.

[0027] The second portion 11 is suitably cylindrical in shape to match the shape of the pole 101 . Moreover, the diameter of this cylinder should be larger than the inner circumference 101b of the pole 101 so that the second portion 11 does not fall into the pole 101. By extension, the second portion 11 may have any shape as long as it does not fall into the pole 101. It is preferable that the second portion 11 is as small as possible in the height direction, but it may be the same in shape, size, color, and height as a cover that is normally attached to the pole 101, for example. The second portion 11 may be the same color as the pole 101 (the object to which it is attached) in order to improve concealment, and may also be the same color as the lid, as described above.

[0028] <Modification> In FIG. 1, the first portion 51 has a cylindrical shape to match the shape of the pole 101 . However, it does not have to be a cylinder. In order to maximize the capacity, the diameter is set to be slightly smaller than the diameter of the pole inner circumference 101b of the pole 101, but this is not limiting. In other words, the first portion 51 may have any shape as long as it can be inserted into the pole 101. For example, it may be a rectangular parallelepiped shape. Also, although the pole 101 is cylindrical, if it is square, the shape can be changed to suit the pole 101. One of the important points of this embodiment (the present invention) is that since a battery can be inserted inside the pole 101, it is possible to use the entire internal space of the pole as a battery space at maximum. Typically, the first portion 51 can be longer than one meter, ensuring an extremely large battery capacity. Nevertheless, there is an advantage in that it can be installed simply by inserting it inside the pole.

[0029] FIG. 2 is an explanatory diagram of the surveillance camera 1 system.

[0030] As shown in FIG. 2, the surveillance camera 1 is capable of exchanging information with an operating device or the like using a communication network 301 (the Internet, a mobile phone network, or the like). It is also possible to communicate directly with the operating device (wirelessly, via WIFI, Bluetooth, etc.) without going through the communication network 301. If anything, it is considered that cases where communication network 301 is not used are generally more common. The parent device can be a personal computer 302, a mobile phone 304, or any other dedicated device. Also, the system may be such that image data and the like are unconditionally stored in the server 305 for storage.

[0031] The surveillance camera 1 is operated by an operating device (personal computer 302, mobile phone 304). The operating device can display an image from the camera unit 21 to the user. Then, the user can operate the camera unit 21 . For example, the subject of image capture by the camera unit 21 is designated, and the associated focus and zoom operations are performed. In addition, the movable portion 11d is also operated. Recording operations etc. are also carried out.

[0032] FIG. 3 is a block diagram of a signal processing system of the surveillance camera 1. As shown in FIG.

[0033] FIG. 3 is a block diagram showing a signal processing system of the surveillance camera 1 of FIGS.

[0034] As shown in FIG. 3, the surveillance camera 1 is configured with a control unit 71, which is the center of control and processing, a battery unit 74, a communication unit 31, a microphone unit 75, an imaging unit 73, and a memory unit 72, each of which is commonly connected to a system bus or the like consisting of multiple lines for addresses, data, and control.

[0035] <Configuration and Effects of the Embodiment> The surveillance camera 1 of the present invention has a first part 51 that is inserted into the interior of the object to which it is attached, and a second part 11 that is larger than the first part 51, has a shape that does not fall into the interior of the object to which it is attached, and has at least a camera unit 21. With this configuration, it can be easily installed on a structure such as a pole.

[0036] Preferably, it has a first portion 51 having a diameter smaller than the inner diameter of the pole 101 to which it is attached, and a second portion 11 having a diameter larger than the first portion 51 and larger than the inner diameter of the object to which it is attached. With this configuration, it can be easily installed on a pole.

[0037] Preferably, the first portion 51 houses a battery 52 . With this configuration, a battery with a large capacity can be mounted.

[0038] Preferably, the second portion contains at least an antenna portion 31a for communication. With this configuration, it is possible to perform stable communication while maintaining confidentiality.

[0039] Preferably, the camera portion 21 rotates horizontally relative to the second portion 11 . With such a configuration, the imaging range of the camera section 21 can be expanded.

[0040] Preferably, the rotation and focus of the camera unit 21 are controlled by control instructions from an external terminal. With such a configuration, the surveillance camera 1 can be more appropriately operated by the user, and the target of surveillance can be monitored more reliably.

[0041] Preferably, the second portion 11 does not have any portion that emits light, at least during monitoring. With such a configuration, the second portion can emit light, thereby preventing the surveillance subject or the like from finding the surveillance subject.

[0042] Preferably, the colour of the second portion 11 is the same as the colour of the object to which it is attached. With such a configuration, confidentiality can be improved.

[0043] According to the present invention, it is possible to provide a surveillance camera that can be mounted at the upper end position of a pole. [Explanation of symbols]
