Ignore this and do not turn on the lights or turn off the lights.

As shown in FIG. 2, the integrated surveillance camera 200 includes a camera unit 210 and a light switch unit 220, and the camera unit 210 and the light switch unit 220 are integrally formed.

The camera unit 210 captures an image of a predetermined region, detects an image movement in a setting region of the photographed predetermined region, and outputs a lighting control signal to the light switch unit 220 when a movement of a person is confirmed in the setting region. If the human motion is not confirmed in the setting area in the lit state, the light control unit 220 outputs an unlit control signal.

Here, since the motion detection of the camera image is already commercialized and widely known, a detailed description thereof will be omitted.

The light switch unit 220 lights or turns off the light 300 according to the control signal of the lighting of the camera unit 210 or the ON / OFF manual operation of the auxiliary switch 224.

The camera unit 210 includes an IP camera 211, a microphone 212, an illuminance sensor 213, an infrared (IR) LED 214, a camera controller 215, and a TCP / IP interface 216. The light switch unit 220 is configured to include a light control unit 222 and the auxiliary switch 224.

The IP camera 211 captures an image of a predetermined area by using a surveillance camera, for example, a CCTV camera or a CMOS camera, connected to the Internet network 500.

The IP camera 211 is capable of PTZ control and includes a position controller, a decoder, an image compression chip, a CPU, and an IP server.

The image of the IP camera 211 may be used for monitoring or motion detection for access monitoring and may be stored in a storage device such as a DVR.

As shown in FIG. 3, the TCP / IP interface 216 is connected to exchange information or signals with the manager server 600 connected to the Internet network 500, and the IP server and the camera controller of the IP camera 211. 215 is connected.

The microphone 212 notifies the manager server 600 by voice through the TCP / IP interface 216 and the internet network 500 by voice input, for example, in case of an emergency.

The illuminance sensor 213 senses the illuminance around the integrated surveillance camera 200 and outputs it to the camera controller 215.

The infrared (IR) LED 214 is turned on under the control of the camera controller 215 to allow the IP camera 211 to photograph a predetermined area at night to detect movement.

The camera controller 215 is connected to the CPU, the IP server, and the TCP / IP interface 216 of the IP camera 211.

The light control unit 222 of the light switch unit 220 lights up the light 300 according to the control signal of the camera control unit 215 or the ON / OFF manual operation of the auxiliary switch 224.

The auxiliary switch 224 is installed on the front of the light switch body in which the IP camera 211 is built, and enables the light 300 to be turned on by manual operation of a person.

The manager server 600 is an interface for receiving video and audio data through the Internet network 500, an AV stream receiver, a controller, a decoder, a video signal processor, a video display, a voice signal processor, a manager interface, a storage (DVR), It includes a microphone and a speaker.

In addition, the audio amplifier 410 and the speaker 420 may be further provided apart from the integrated surveillance camera 200.

The audio amplifier 410 narrows the sound signal input through the manager server 600, and the speaker 420 outputs the amplified sound signal as sound.

Referring to the operation of the above-described configuration, first, the IP camera 211 is built in the light switch body 201 to shoot a predetermined area in real time to the video signal to the camera control unit 215 and the TCP / IP interface 216 Output

The camera controller 215 detects a motion of a set area image among the images of a predetermined area to determine whether there is a movement of a person, and outputs a lighting control signal to the light controller 222 when there is a movement of a person.

In addition, the light 300 may be turned off using the sensing illuminance value of the illuminance sensor 213.

That is, when the illuminance sensor 213 senses the illuminance around the integrated surveillance camera 200 and outputs an illuminance signal to the camera control unit 215, the camera control unit 215 detects the illuminance value of the illuminance sensor 213 and the illuminance sensor 213. The first reference illuminance value is compared to determine whether the lamp is turned on according to the ambient brightness.

The camera control unit 215 outputs a lighting control signal to the light control unit 222 only when it is determined that there is a movement of a person in the setting area and that the first reference illuminance value is larger (because the surroundings of the integrated surveillance camera are dark). The light control unit 222 may thereby turn on the light 300.

When there is no human movement in the setting area or the sensing illuminance value is greater than the first reference illuminance value (because the surroundings of the integrated surveillance camera are sufficiently bright), the control signal is not output to the light control unit 222.

When the lamp 300 is turned on, the camera controller 215 continuously detects the movement in the set region image among the images captured by the IP camera 211 and determines that there is no human movement. The lights out control signal is output, and the light control unit 222 turns off the light 300 that was turned on by this.

Unlike this, the camera controller 215 may turn on the lamp 300 at a time of movement of a person and output a light control signal to the lamp controller 222 after a predetermined time elapses.

Meanwhile, the camera controller 215 compares the sensing illuminance value of the illuminance sensor 213 with the preset second reference illuminance value and determines whether the infrared LED is turned on according to the ambient brightness.

When it is determined that the second reference illuminance value is larger and the infrared LED lighting condition is turned on, the infrared LED 214 is turned on so that the IP camera 211 clearly captures a predetermined area even in the dark night so that motion can be detected.

In the state where the infrared LED 214 is turned on, when the day is bright and the sensing illuminance value is larger, the infrared LED 214 is turned off by determining that the infrared LED is turned off.

In this state, when the IP camera 211 or the camera control unit 215 fails and the lights of the light 300 cannot be controlled using the camera unit 210, the auxiliary switch 224 provided in the light switch main body. Can be used to turn the lamp on and off manually.

The position controller provided in the IP camera 211 controls the direction and the zoom of the IP camera 211 in order to receive a control signal from the camera controller 215 and obtain a valid image.

The TCP / IP interface 216 transmits the control data of the camera controller 215 and the image data of the IP camera 211 to the manager server 600 through the Internet network 500, and receives a signal from the manager server 600. Receives and transmits to the camera control unit 215 or the IP camera 211 to enable communication between the camera control unit 215 and the IP camera 211 and the manager server 600, under the control of the camera control unit 215 The image data is transmitted to the manager server 600.

Through this, the manager server 600 may remotely control the lighting of the infrared LED 214 or the light 300.

The camera controller 215 interworks with the CPU and the IP server of the IP camera 211 and the TCP / IP interface 216 to transmit / receive voice and transmit information between the IP camera 211 and the TCP / IP interface 216. do.

Accordingly, the camera controller 216 includes a remote camera control function for controlling the direction, distance, angle, etc. of the IP camera 211, and an image data control function for adjusting the level, method, speed, etc. of the encoded image data. The entire surveillance camera 200a, 200b, ..., 200n is controlled according to a manager's command input through the manager interface of the manager server 600.

In addition, the camera controller 215 communicates with the manager server 600 to receive and process various control commands or setting commands, and controls an operation to transmit an image received from the IP camera 211 to the manager server 600. .

In addition, the camera controller 215 determines that the voice (sound) of a predetermined size or more is input from the microphone 212 as an emergency situation, and transmits the voice information to the manager server 600 through the TCP / IP interface 216. send.

In addition, when a sound signal is input from the manager server 600, the camera controller 215 may output the sound signal to the audio amplifier 410 to amplify the sound signal and output the sound signal through the speaker 420.

In this way, there is a two-way audio function between the integrated surveillance camera (200a, 200b, ..., 200n) and the manager server 600 to directly talk to the remote manager and to be alerted through the speaker 420 in case of illegal intrusion outside the specific facility. Can be.
