Abstract

PURPOSE: A recording system of surveillance camera is provided to freely change setup of a menu screen during recording independently of a surveillance screen recorded. CONSTITUTION: A recording system comprises a first on screen display(OSD) part(10); a video integrated circuit(IC) part(20); a second OSD part(30) electrically connected in order and an output monitor(40) connected to a back end of the connection. The first OSD part indicates an event happening time of image signal input by a camera. The video IC part records the event happening time indicated by the first OSD part and plays a recorded part of the time a user wants. The second OSD part indicates mode setup the user wants.

Description

Recording system of surveillance cameras {A Picture Recording System of Supervisory Camera}

The present invention relates to a screen recording method of a surveillance camera, and more particularly, to exclude a case in which a menu of a recording control function, that is, an OSD screen is recorded as it is, when recording a monitor screen on which an on-site situation is transmitted through a surveillance camera. Apart from the surveillance screen recorded during surveillance camera recording, it is possible to change the set-up contents of the menu screen during recording to a desired position, and to record the surveillance camera screen to prevent the recording.

In the conventional case, as shown in FIG. 3, in the method of connecting to an OSD, a video IC, and a monitor, in a recording method using a VCR, a menu screen displayed during recording is recorded as it is, and an important part of the surveillance camera recorded by the menu screen Even if the surveillance screen is lost due to a mistake of the surveillance user's operation or the menu screen is not displayed on the screen during recording, the user's other purposes during the recording operation occupy most of the surveillance VCR operation. However, there was a problem that cannot change the set-up contents.

Accordingly, the present invention has been made in view of the above-described problems, and provides a screen recording method of a surveillance camera that allows the setup contents of a menu screen to be changed freely during recording separately from the monitoring screen in a recording state. Is there.

The present invention provides a first OSD unit for displaying the event occurrence time of the video signal input by the camera in order to achieve the above object; A video IC unit 20 for recording an event occurrence time presented by the camera input signal and the first OSD unit 10 and reproducing a time recording portion desired by a user; The second OSD 30 which displays each mode setting desired by the user is electrically connected to each other in sequence, and after that, the second OSD 30 is connected to the output monitor 40.

Hereinafter, with reference to the accompanying drawings, the configuration and operation of the screen recording method of the surveillance camera of the present invention will be described based on the preferred embodiment.

(Example)

The accompanying drawings, FIG. 1 relates to a configuration diagram for showing a structure in actual use of the present invention, and shows a state in which an OSD control screen output to the monitor 40 is sent out.

FIG. 2 is a schematic block diagram of the present invention, wherein a first OSD controller 10 is connected to a path through which video is input, and a video IC unit 20 for controlling a video input is connected to a rear end thereof. And a second OSD unit 30 for menu screen control and a monitor 40 for screen output are sequentially connected.

In the initial use of the present invention, an external input video signal S1 is transmitted through a surveillance camera, and video together with a character (date, time, site ID, etc.) signal S2 generated in the first OSD unit 10 is generated. It is input to the IC unit 20, and the video IC unit 20 superimposes and outputs the signals S1 and S2.

At this time, the menu screen (time setting, scheduled recording, alarm setting, etc.) signal S4 generated by the second OSD unit 30 is sent out, and the signal S3 or S4 is operated on the monitoring monitor 40 by a user operation. ) Is printed.

That is, when the surveillance screen of the surveillance camera is output to the monitor 40 as it is, the menu screen of the second OSD unit 30 is output on the monitor 40 as shown in FIG. The user can set the functions for each menu such as recording time, scheduled recording, alarm setting, and OSD location.In this case, the menu change screen through the second OSD unit 30 is output to the monitor. It is not actually recorded on the recording tape.

Meanwhile, the monitoring screen is monitored when the menu setting is completed in the state where the position of the first OSD unit 10 is changed to the upper right as shown in FIG. 1 by designating the position of the OSD in the second OSD unit 30 of the menu screen. In the situation output to 40, the current time and date are recorded in the upper right corner so that it can be easily grasped when the recorded screen is played.

Since the signal of the first OSD unit 10 in which the date and time are displayed on the screen of the monitor 40 to which the signal of the surveillance camera is input is controlled by the video IC unit 20, the menu setting is performed again on the screen. 2 Even if the menu screen of the OSD unit 30 is output, only the monitoring screen is recorded separately from the output screen, and in FIG. 1 at the request of the recording monitor during the recording of an arbitrary site by the monitoring camera. As you can see, if you change the date or the position of the OSD while the menu screen is open, the setting screen for this is not recorded on the recording tape, only the scene of the monitoring site is recorded.

As described above, the screen recording method of the surveillance camera of the present invention is to allow the user to freely change the setup contents of the menu screen during recording separately from the surveillance screen being recorded. It is a useful invention that can exclude the disappearance of the screen.

As described above, the present invention has been described based on the limited embodiments, but the present invention is not limited to the above-described embodiments, and the present invention has ordinary knowledge in the technical field to which the present invention belongs without departing from the gist of the present invention. Various changes and modifications can be made by the person, which naturally belongs to the scope of the present invention.
