The captured video data is received by the mobile terminal 3 via the communication unit 33 and continuously displayed by the display unit 31.

  The central control unit 22 that has received the detection signal from the first detection unit 27 continues to execute the program. As a result, the network camera 2 enters the “mode switching state” described above (step S104).

  When the state of the network camera 2 is changed to “mode switching state”, input information (hereinafter referred to as “second input information”) for selecting and determining any equipment is again transmitted from the mobile terminal 3 to the network. It is transmitted to the camera 2 (step S105).

The network camera 2 that has received the second input information continuously executes the program by the central control unit 22 and transmits an output signal to the horizontal turning mechanism unit of the rotation base 221 through the camera control unit 23.
And the said horizontal turning mechanism part which received the said output signal starts predetermined regulation operation | movement defined beforehand.
As a result, the camera 21 held by the camera unit 223 starts to turn in the horizontal direction again with respect to the rotation base 221 via the unit support base 222 (step S106).

The camera 21 that has started to turn in the horizontal direction again stops when it reaches the aforementioned “output position” (see FIG. 3B) (step S107).
Thereafter, the second position sensor 62 detects the position of the camera 21 (more specifically, the unit support base 222) (step S107), and transmits a detection signal to the central control unit 22 via the second detection unit 28. To do.

In the remote control system 1 according to the present embodiment, the camera 21 still has all the equipment that constitutes the equipment equipment group 5, that is, even if the stop position is changed from the “mode position” to the “output position”. The images of the shutter 51, the illumination device 52, and the air conditioner 53 that can be selected and determined as the “second input information” are captured in real time.
The captured video data is received by the mobile terminal 3 via the communication unit 33 and continuously displayed by the display unit 31.

  The central control unit 22 that has received the detection signal from the second detection unit 28 continues to execute the program, and transmits an output signal to any of the equipment selected and determined via the equipment control unit 26 (step). S108).

  Then, the equipment that has received the output signal executes a predetermined operation (for example, an opening operation or a closing operation in the shutter 51) (step S109), and when the operation is completed, the camera 21 The imaging operation is finished (turned off), and the operation of the remote control system 1 is finished.

As described above, in the remote control system 1 according to the present embodiment, the facility device group 5 is remotely controlled through the network camera 2.

Transmission is executed and remote control of the equipment group 5 is performed.

  More specifically, in a state where the camera 21 is stopped at the “mode position”, the network camera 2 is in the “mode switching state”, and any equipment is selected based on the “second input information”. Further, when the camera 21 is stopped at the “output position”, an output signal to the selected equipment is transmitted from the equipment control section 26 of the network camera 2.

  And in the remote control system 1 in this embodiment, as mentioned above, even if the stop position of the camera 21 is either the “mode position” or the “output position”, all the devices constituting the equipment group 5 are included. Since it is possible to capture an image of the equipment in real time, it is possible to perform remote control of the equipment group 5 while confirming the video.

In the present embodiment, the remote control of the equipment group 5 is performed based on two types of stop positions (“mode position” or “output position”) of the camera 21, but the present invention is not limited to this. It is not a thing.
For example, by providing two or more position sensors, a plurality of stop positions corresponding to the “mode position” (the same number as the plurality of facility devices constituting the facility device group 5) are provided, and the camera 21 is located at these stop positions. It is good also as a structure that a predetermined installation apparatus is selected automatically by stopping each.
However, in this case, at each stop position, the camera 21 needs to be able to capture the video of the selected equipment in real time.

  As described above, the remote control system 1 according to the present embodiment is a remote control system that performs remote control of the equipment device group 5 including a plurality of equipment devices (such as the shutter 51, the lighting device 52, and the air conditioner 53).

As a result, the reliability of the entire system is improved.

  Further, in the conventional remote control system, a control device or the like for performing operation control of a plurality of equipment is separately required. However, in the remote control system 1 in the present embodiment, the network camera functions as the control device. It can be replaced by 2 and is economical.

  In the remote control system 1 according to the present embodiment, the camera 21 can be pivoted in the horizontal direction via the unit support 222, and can be pivoted in the vertical direction via the camera unit 223.

It is supposed to detect a striker (metal piece) 225 that is fixed to the base plate.

As described above, in the remote control system 1 according to the present embodiment, the remote control system 1 according to the present embodiment is configured by the proximity switch that can be attached to the outside of the network camera 2 (more specifically, the rotation base 221). It is going to be composed.
Therefore, for example, even if it becomes necessary to change the position and number of position sensors in the future, the remote control system according to this embodiment can easily cope with it.

Further, as described above, the configuration of the striker 225 and the first and second position sensors 61 and 62 is not particularly limited as long as the stop position of the unit support base 222 can be grasped.
