The CCTV camera includes a fixed camera, a dome camera capable of rotating up and down in the small camera, a PTZ (Pan Tilt Zoom) camera, and a dome infrared (IR) camera equipped with an infrared LED suitable for nighttime shooting Is used.

PTZ (Pan, Tilt, Zoom) The camera has PTZ control function. Pan is a function to move the camera left and right while fixing the position of camera. Tilt (tilt up, tilt down) in / out provides a function to zoom in / out the image screen by focusing the camera's focal distance at a close distance or at a distance.

The SD camera provides SD (640 * 460 = 307,200 pixels, 24, 15fps) resolution image quality and it is divided into dome camera / square camera according to the installation position and is most widely used.

The HD camera uses a 1.3 / 2 / 3M Pixel lens, which is a higher resolution camera than the existing SD camera. The HD camera is HD (1280 × 720 = 921,600 pixels, 30 fps) or Full HD (1920 × 1080 = 2,073,600 pixels, 30 fps) It provides high resolution image quality and shows a clearer surveillance screen.

A DVR (Digital Video Recorder) is a digital video storage device that encodes an image captured by a plurality of cameras connected by a cable within a distance of 1.8 km, compresses and stores the image on a hard disk, and distributes and displays images for each camera channel. It is a system that integrates switch, screen divider, VCR (video player) sensor and alarm controller which change screen which is in the analog system separately.

NVR is a dedicated PC server for video recording, monitoring, event management and playback of a camera or video server installed on the network.

As a related art 1, Patent Registration No. 10-1735780 discloses a "method and terminal for detecting an intrusion in a smart home security system ". The terminal measures the strength of a signal received from a wireless heterogeneous terminal and calculates a change value of the measured received signal strength. The MS calculates the received signal strength change probability using the calculated received signal strength change value, and compares the received signal strength change probability with a predetermined threshold to determine whether or not the intruder intrudes.

1 is a diagram illustrating a conventional smart home security system.

The smart home security system includes a base station 100, a wireless LAN AP (Access Point) 200, a Bluetooth device 300, a terminal 400, a gateway 500, and a control server 600.

The base station 100 performs cellular communication for transmitting and receiving signals with the terminal 400 belonging to the base station. The base station 100 transmits a pilot signal S1 for measuring a received signal strength (RSS) at a predetermined time interval. Here, the pilot signal S1 for RSS measurement may be a pilot signal that the base station 100 transmits specifically for smart home security or a pilot signal used for general signal transmission.

The WLAN AP 200 performs WiFi communication with the terminal 400. [ The WLAN AP 200 according to the embodiment of the present invention transmits a pilot signal S2 for RSS measurement at a predetermined time interval. Here, the pilot signal S2 for measuring the RSS may be a pilot signal that the WLAN AP 200 transmits specifically for smart home security or a pilot signal used for general signal transmission.

The Bluetooth device 300 performs Bluetooth communication with the terminal 400. Although the Bluetooth device 300 is shown in FIG. 1 as being installed in a TV, it is natural that the Bluetooth device 300 may be installed in a home appliance other than a TV. The Bluetooth device 300 transmits a pilot signal S3 for RSS measurement at regular time intervals. Here, the pilot signal S3 for RSS measurement may be a pilot signal that the Bluetooth device 300 transmits specifically for smart home security, or may be a pilot signal used for general signal transmission.

The MS 400 measures the RSS of the received signal with respect to the pilot signal S1 received from the BS 100 and measures the strength of the received signal with respect to the pilot signal S2 received from the WLAN AP 200 RSS). The terminal 400 measures the RSS (RSS) of the received signal with respect to the pilot signal S3 received from the Bluetooth device 300. The terminal 400 analyzes signals by combining the strengths of the received signals measured through the pilot signals received from the respective wireless heterogeneous systems 100, 200, and 300, and determines whether intruders intrude through signal analysis. The terminal 400 may be a smart phone capable of 3G communication or LTE communication.

When the signal transmitted between the base station 100 and the terminal 400 is intruded, the strength RSS of the received signal is almost constant. However, when there is an intrusion, the intensity (RSS) of the received signal has a large fluctuation range. The received signal strength RSS of the signal transmitted between the wireless LAN access point 200 and the terminal 400 and the received signal strength RSS of the signal transmitted between the Bluetooth device 300 and the terminal 400 are also intruded If there is a large fluctuation. The terminal 400 determines whether or not the intruder intrudes using the variation width of the received signal strength RSS.

The terminal 400 transmits intrusion information to the base station 100 when the intruder determines that the intruder has intruded using the fluctuation range of the received signal strength RSS and the base station 100 transmits the intrusion information back to the gateway 500 To the control server (600). The control staff finally confirms the intrusion information transmitted to the control server 600, and the control personnel can go out to check on-site situation or contact the police.

The terminal 400 according to the embodiment measures and analyzes the received signal strength RSS of signals transmitted from the different types 100, 200, and 300 to determine whether or not the intruder intrudes.

As a related art 2, Patent Publication No. 10-2014-0028238 discloses a " home security method and system with enhanced network security ", and a home terminal (M2M device, gateway, etc.) logically separated from a general authorized network ) And a management server of M2M (machine to machine) service provider of the network domain, it is possible to access a home terminal or a management server through a public network by configuring a logical virtual point-to-point network And provides a home security method and system that enhances network security that is originally blocked.

However, the conventional home security system has a CCTV system including sensors and cameras. However, it is interlocked with a door open / close control system and a sprinkler control system as a doorbell (IoT device), an IOT gateway, a home server, There was no function to control the sprinkler operation.
