Description

UPS type NVR unit having battery power pack of super capacitor type and Uninterrupted Networking system and method for smart CCTV using the same}

The present invention relates to an uninterrupted networking system and method for an intelligent security camera using an uninterruptible NVR device including a supercapacitor type battery power pack capable of responding to power and network abnormalities.

A CCTV (Closed Circuit Tele-Vision) system used as a security camera is composed of a plurality of cameras, a monitor that outputs captured images, and an NVR that records images so that they can be reproduced and viewed.

In general, an IP camera is a camera that is connected to the Internet by wire or wireless and is composed of a camera module, decoder, video compression chip, CPU, network transmission chip, etc., and converts an analog signal acquired from the camera module into a digital signal by a decoder. Network Video Recorder (NVR) is a dedicated PC server for video recording, monitoring, event management, and playback of cameras or video servers installed on the network. It is a dedicated storage device. In recent years, security systems using IP cameras and NVRs configured as described above have been widely used due to their relatively free scalability and the ability to minimize the work for separate cable connections.

The CCTV camera module is installed in the surveillance range of a certain area and receives power from the power supply device through the LAN cable to monitor the set surveillance range.

The intelligent CCTV system automatically notifies when a specific situation such as a disaster such as a fire or a crime occurs while a computer monitors CCTV images at all times, and has a function of recognizing and tracking faces according to a set program if necessary.

Such an intelligent CCTV system must always ensure a technical environment that can be monitored at all times. However, unexpected causes such as instability of power supply, power failure, and lightning, and artificial network blocking to remove information may cause data loss and paralysis of monitoring functions.

In this way, when the power supplied to the CCTV module or the network connection is blocked, the operation and information transmission of the CCTV is stopped, and crimes or accidents occurring within the monitoring range cannot be monitored during the stopped time.

In order to prevent this, a method of installing a UPS in parallel with an NVR or a power supply has been studied. However, the method of installing the UPS in parallel with the NVR or power supply cannot prevent loss of information when the power supply connected to the CCTV camera module or the connection state of the network LAN cable is bad or artificially blocked.

As another method, Korean Registration Publication No. 10-1910911 discloses a method of providing an uninterruptible power supply and a memory to the CCTV camera module itself, and recording using its own battery when the power is cut off and storing it in the built-in memory.

In order to provide an uninterruptible power supply and a memory in addition to the above CCTV camera module, there is an inconvenience in that the existing installed CCTV camera module must be replaced. In addition, when the connection of the network LAN cable is blocked, it is difficult to check the information in real time.
