Description

Alarm monitoring device {Video audio and alarm monitoring apparatus}

The present invention relates to an alarm monitoring device, and more particularly, to an improvement of an alarm system that performs improved performance and operation by providing an additional device to a conventional alarm monitoring system.

In modern society, various kinds of alarm systems, that is, alarm monitoring systems, are widely used to reduce labor costs, monitor remote sites, and increase the convenience of residents' lives.

In addition, a variety of configurations have been devised to supplement police personnel who are lacking in the police service, and to monitor and detect remote areas and difficult areas where it is difficult to patrol.

The alarm monitoring system for monitoring public facilities such as crime prevention, security, road patrol, crime monitoring, multiple gathering banks, department stores, and the like from the prior art is exemplarily shown as a house in FIG.

In order to remotely monitor and monitor the plurality of surveillance zones (S1, S2, S3, .Sn) spaced apart from each other, an alarm device having a plurality of surveillance cameras and an alarm sensor (not shown) may be provided in each surveillance zone ( S1, S2, S3, .Sn)

The output signal from the remote monitoring, alarm sensor, etc. from these are connected to the monitoring unit (M) consisting of a rack of the central monitoring center (C) to centrally manage by an electrical connection such as a wire. Therefore, there is no problem in the case of houses concentrated in a single site, but electricity from a monitoring area (S1, S2, S3, .Sn) that flows like a remote patrol or a remote area or a police patrol car It has a problem that it is very difficult to receive a signal and to accept it in the central monitoring center (C).

In particular, in the case of remote homes, most of the wiring work is required and installation costs are very high. Most alarm monitoring systems are operated only in an urban area or in a single residential area.

In addition, the conventional alarm monitoring system is connected to the central monitoring center (C) by such a wired connection, so that the central monitoring center (C) must be transmitted to the patrol police car or the like for the on-site dispatch or early departure. By delaying the delay and increasing the number of manpower therein, the efficiency of the alarm monitoring system becomes extremely low.

In addition, in the case of the conventional configuration, the central monitoring center C unilaterally determines and takes subsequent measures based on the video-audio and alarm response signals from the surveillance zones S1, S2, S3, .Sn. It also had the problem of not being quick.

The alarm monitoring apparatus of the present invention devised in view of the above-described problems of the conventional configuration has a detected alarm output in each monitoring area S1, S2, S3, .Sn, that is, an image signal and an alarm of a monitoring camera. Automatically connects and transmits the voice signal from the sensor to the central monitoring center (C), and collects it from the central monitoring center (C) to make a database and transmit it to the police patrol car, police station, security company, etc. It is characterized by improving the efficiency of the alarm system by providing.
