Abstract

PURPOSE:To not only video record and reproduce an image picked up picture by a television camera, but also to display a warning image on a monitor television by reading out display data for warning and displaying it on the monitor television when disaster prevention information is detected. CONSTITUTION:A memory 9 is stored previously with various warning display data for a fire, a gas leak, a trepass, etc. For example, the fire sensor of a security unit 11 detects the fire and outputs its detection signal and then a security detecting circuit 10 sends the disaster prevention information to a memory control circuit 7a. The memory control circuit 7a reads display data for fire warning stored in the memory 9 and writes it in a memory 5, out of which data is read so that its image is displayed continuously on the monitor unit 2. Consequently, the picture which is image picked up by the television camera is video recorded and reproduced and further if the fire or gas leak is caused, the warning image is displayed on the monitor television.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention is applicable to HA of door intercom handsets used in homes, etc.
(Home Automation) This invention relates to an image recording device that can be connected to a device.

BACKGROUND ART FIG. 2 shows a conventional image recording device, 3 is a video signal processing circuit that separates a composite video signal captured by a camera unit 1 into a video signal and a synchronization signal, and 4 is a video signal processing circuit. An A/D converter that converts the video signal from the circuit 3 into a digital signal; 5 is a memory for storing the digital signal converted by the A/D converter 4; 6 is a digital signal read out from the memory 5; A D/A converter converts the signal into an analog signal and outputs it to the monitor unit 2; 7 is a memory control circuit that controls writing and reading from the memory 5 using synchronization signals from the video signal processing circuit 3; This is a call detection circuit that detects a call from a call switch or the like of the illustrated door intercom handset.

In the above configuration, for example, when the camera unit 1 is placed at the entrance etc. and used as a video door intercom recording device, the user can have a conversation with a visitor while looking at the monitor unit 2 in the home mode, and when the user is away In this mode, when the call detection circuit 8 detects a call, the memory control circuit 7 stores one screen worth of video data of the visitor in the memory 5, so that after the user returns home, this video data is read out and displayed on the monitor unit 2. can be played.

Problems to be Solved by the Invention However, the conventional image recording device described above has a problem in that it lacks versatility because it only has the function of recording and reproducing images captured by the television camera 1.

SUMMARY OF THE INVENTION In view of the above-mentioned conventional problems, it is an object of the present invention to provide a versatile image recording device.

Means for Solving the Problems In order to achieve the above object, the present invention provides a storage means for pre-storing display data for warning in the event of a fire, gas leak, etc.; A disaster prevention information detecting means is provided, and when disaster prevention information is detected, the warning display data is read out and displayed on a monitor television.

Function The present invention has the above-mentioned configuration, and not only has the function of recording and reproducing images captured by a television camera, but also has the function of preventing fires, fires, etc.
When a gas leak or the like occurs, a warning image can be displayed on a monitor television, and therefore a versatile image recording device can be realized.

EXAMPLES Hereinafter, the present invention will be described in detail with reference to the drawings. FIG. 1 shows a professional 7 illustrating an embodiment of the image recording device according to the present invention.
This is a diagram.

In FIG. 1, reference numeral 3 denotes a video signal processing circuit that separates the composite video signal captured by the camera unit 1 into a video signal and a synchronization signal, and 4 converts the video signal from the video signal processing circuit 3 into a digital signal. A/D converter that converts into
5 is a memory for storing the digital signal converted by the A/D controller 4; 6 is a D for converting the digital signal read from the memory 5 into an analog signal and outputting it to the monitor unit 2; /A converter, 7a,
As will be described later, a memory control circuit performs writing and access control in the memory 5 based on a synchronization signal from the video signal processing circuit 3, and a call detection circuit 8 detects a call by a call switch of a door intercom handset (not shown). It is a circuit.

9 is a memory for storing in advance various warning display data in the event of a fire, gas leak, intrusion, etc.;
This is a security detection circuit that detects disaster prevention information from a security unit 11 that includes various sensors for detecting fire, gas leak, intrusion, etc.

Next, the operation of the above embodiment, particularly the operation of the memory control circuit 7a, will be explained.

In FIG. 1, for example, when a fire sensor of the security unit 11 detects a fire and outputs a detection signal,
The security detection circuit 10 outputs the disaster prevention information to the memory control circuit 7a.

The memory control circuit 7a uses this disaster prevention information to control the memory 9.
The display data for fire warning stored in is read out and written into the memory 5, and the data is read out from the memory 5 so that this image is continuously displayed on the monitor unit 2.

For example, when the camera unit 1 is placed at the entrance or the like and used as a video door intercom recording device, the user can have a conversation with a visitor while looking at the monitor unit 2 in the at-home mode, and in the away mode. When the call detection circuit 8 detects a call, the memory control circuit 7a changes to 1.
Video data of the visitor for a screen is stored in the memory 5, so that the user can read this video data and reproduce it on the monitor unit 2 after returning home.

Therefore, according to the above embodiment, in addition to being able to be used as a door intercom device with a camera, warning images can be displayed on the monitor unit 2 in the event of a fire, gas leak, intrusion, etc. Therefore, it is possible to realize an image recording device with a high level of performance.

DETAILED DESCRIPTION OF THE INVENTION As described in detail, the present invention includes a storage means for pre-storing display data for warning when a fire, gas leak, etc. occurs, and a means for detecting disaster prevention information such as a fire, gas leak, etc. When disaster prevention information is detected, the warning display data is read out and displayed on the monitor TV, so it not only has the function of recording and playing back images captured by the TV camera, but also has the function of preventing fires, etc. When a gas leak or the like occurs, a warning image can be displayed on a monitor television, and therefore a versatile image recording device can be realized.
