Abstract

PURPOSE:To surely perform the recognition of the status of a site and the transmission of a message by providing a video camera to be operated by receiving output from a sensor, and a delivery part to send a video signal photographed by the video camera via a telephone circuit. CONSTITUTION:When abnormality is detected by the sensors 1 and 2, the detecting signal is processed by a central processing part 4, and the video camera 5 is operated, then, the site is photographed. The video signal from the video camera 5 is generated from a video signal generating part 6, and is supplied to a facsimile signal synthesizing part 8. A facsimile signal is synthesized at the part, and it is sent to a facsimile terminal equipment 10 with a telephone number set in advance via an NCU9, then, the video of the site is transmitted to a receiver.

Description

[Detailed description of the invention] [Industrial application field].

The present invention relates to a monitoring device using a telephone line.

[Conventional technology] Traditionally, fire sensors,
There is a monitoring system that receives signals from various sensors of an intrusion sensor and sends a prerecorded voice to a receiver of an arbitrary telephone number to contact the receiver.

[Problems to be solved by the invention] Since the above-mentioned system transmits audio, the message cannot be transmitted when the recipient is absent, and no record of reception is left.
There are drawbacks such as difficulty in making synthesized speech clear and leakage of information to third parties.

Also, since only predetermined messages are sent, there is a drawback that even if an abnormality is reported, the situation at the site cannot be grasped.

The present invention eliminates each of the above-mentioned drawbacks by transmitting the on-site situation in the form of images.

[Means for Solving the Problems] The present invention provides information in the form of images by providing a video camera that receives the output from each sensor and filming the scene, and transmitting the video signal via a telephone line. It is designed to be sent out.

[In the drawings of the embodiment, 1 and 2 are sensors for crime prevention or disaster prevention, 3 is a sensor human power section, 4 is a central processing section consisting of a CPU, etc., and 5 is a video camera for photographing the sensor installation site. . Reference numeral 6 denotes a video signal generation section that generates a video signal captured by a video camera. Reference numeral 7 denotes a video signal sending section, which includes a facsimile signal combining section 8 and an NCU (network control circuit) 9. 10 is a receiving facsimile terminal.

In the above configuration, when an abnormality is detected by the sensors 1 and 2, this detection signal is processed by the central processing unit 4, and the video camera 5 is operated to photograph the scene. A video signal from the video camera 5 is generated from a video signal generating section 6 and supplied to a facsimile signal combining section 8. There, the facsimile signals are combined and sent to the facsimile terminal 1 of the preset telephone number via the NCU 9.
0, and the image of the scene is transmitted to the recipient.

Note that the sending unit is not limited to facsimile, and may also use telex.

[Effects of the Invention] According to the present invention, when an abnormality is detected by a sensor, the scene is sent as a video, so the situation at the scene can be grasped at a glance, a reception record is left, and even when the recipient is absent, the situation can be grasped at a glance. This ensures that your message is conveyed when you return home. Furthermore, since voice is not used, it is possible to eliminate the inconvenience of information being overheard by a third party and being leaked.

Furthermore, since no voice line is used, the reception rate on the receiving side is high, and the probability that the message can be transmitted immediately is high.
