Network type monitoring device

Abstract

To provide a networking monitor device where a reproduction terminal can acquire a picture from alarm information from a unit in a monitor area via a network. The networking monitor device consists of a picture input section that receives picture information received from a picture output device such as a camera or a switcher, a coded picture storage section that encodes picture information and stores the coded information, an alarm management section that detects presence of occurrence of an alarm from an alarm generator to store alarm information, and a communication section that receives a request from a reproduction terminal via a network transmits the coded picture stored in the coded picture storage section or the alarm information stored in the alarm amplifier section upon the request therefrom.

Description

Technical field [0001] The present invention relates to techniques that perform image transfer through a network, and more particularly to techniques for monitoring an image of an image of an image of a monitoring machine by a terminal such as a remote computer and an alarm information such as a sensor. Background technique [0002] The configuration of the prior art monitoring system includes monitoring the camera, the switch, the monitor image machine, the image display, and the coaxial cable connected to the above various machines and the control information, the monitoring person must have been Monitor the above-described monitoring of the fixed location of the security room. In addition, the transmission of the alarm information is a system-dedicated line that is separated from the coaxial cable for transmitting images. [0003] In addition, existing network-type image transmitting devices are implemented on PC loading dedicated software on PC connecting a PC (Personal Compu...

AI Technical Summary

Problems solved by technology

[0007] The first problem is that the network distribution of images from safety devices such as cameras and switches, the registration records of alarm information from sensors and the above-mentioned safety devices, and the distribution of the above-mentioned alarm information are realized by different devices. difficult to build relationships

[0008] The second problem is that if an image coding and storage device corresponding to the number of image input channels from cameras and image output devices connected to the network-type monitoring device is provided, the number of parts will be large and the cost will be high.

[0009] The third problem is that in order to cope with various reproduction terminals such as portable terminals such as PCs, mobile phones, and PDAs (Personal Digital Assistants), and information appliances such as TVs, it is necessary to efficiently display different displays for each terminal. Ability and display format correspondence

[0010] The fourth problem is that it is impossible to display the images of multiple channels on the same terminal at the same time by using the image encoding device and the image storage device of one system that can only process one channel by simply switching the image input channel.

[0011] The 5th problem is because only the latest image is stored in the existing coded image storage method, it is difficult to obtain the alarm image before the alarm occurs

[0012] The sixth question is when the second alarm occurs during the storage of the first series of alarm images. Depending on the application, the first alarm image or the second alarm image is required.

[0013] The seventh problem is that there must be special special software for viewing alarm information and obtaining and displaying alarm images

[0018] The twelfth problem is that due to the transmission delay of the network, when controlling a monitoring device with a simple control command, it takes time from the start of a series of operations to the end of the operation, or the accuracy expected by the operator of the monitoring device cannot be achieved. to control the amount of change
