Network surveillance video camera system
First Claim
1. A network surveillance video camera system using a network comprising:
- a plurality of video camera units, each having a different address and generating video data, each including motion detection means for detecting a motion of an image from said video data and communication means for communicating with said network to transmit said video data and an output of said motion detection means;
each of said video camera units including;
sensor input means for receiving a sensor signal;
alarm signal generation means for generating alarm data in response to said sensor signal and said motion detection means to transmit said alarm data and data regarding said alarm data including said sensor signal;
a transmission control protocol/internet protocol circuit made to receive said video data and said alarm data, and coupled to said network for transmitting said video data and said alarm data to said network;
storing means, having a different address and communication means for communicating with said network, for receiving and storing said video data from said video camera units through said network;
display means, having a different address and communication means for communicating with said network, for displaying said video data from said storing means and said video camera units; and
a control server coupled to said network having a different address for automatically communicating with said network to control said addresses of said video camera units, said storing means, and said display means.

Abstract
Monitor camera units, a data storing unit, a control server, and a monitor display are coupled by a network. The monitor camera unit includes a motion detector for detecting motion from video data, a microphone, a traffic monitor, a memory for storing the video data, and a sensor signal input circuit. The traffic monitor monitors the traffic of the network. If the traffic is high, only necessary data or sound data is transmitted. The memory stores the video data in response to the motion detector and a thinning circuit thins the video data from the memory in response to a sensor signal. The control server receives the alarm data from the monitor camera and further receives the alarm type data, time data, position data of a pivoting unit for pivoting the camera unit and transmits the data to the display terminal. In the presence of a loud sound, alarm data is also generated but it is not sent if a switch is OFF. The control server includes a data base storing set of alarm data. If an operator judges one set of alarm data is an error, the set of data is not erased but mark data is correspondingly stored to inhibit searching the set of data. During the night, the exposure and transmitting intervals are increased to prevent the same data from being transmitted twice.
