The device, the method, and the system may provide a noise feedback for each household by analyzing and monitoring a noise level, a noise source location, a noise direction, an occurrence time, a noise type of a noise.

Apparatus, method and monitoring system for measuring noise between floors

Provided is a network camera, including: an event detector configured to detect an event; an image sensor configured to capture an image in response to the detected event; a storage configured to store image data of the captured image; a transceiver configured to transmit and receive the image data over a network; a controller configured to control the event detector, the image sensor, the storage, and the transceiver, to select a single network mode from among a plurality of network modes based on whether power is supplied from an outside, and to configure the network based on the selected network mode; and a power source configured to supply the power to the event detector, the image sensor, the storage, the transceiver, and the controller.

Network camera using hierarchical event detection and data determination

The present invention relates to a front-end event detector for detecting the occurrence of an event before a signal process is generated, and a low power camera system maintaining the low-power mode when idle but activated in normal mode only when the occurrence of an event is detected in the front-end event detector. The front-end event detector according to the present invention comprises: an image sensor for obtaining analog image data and converting them into digital image data; a first buffer memory for storing the digital image data; a first comparator, wherein the next digital image data delivered from the image sensor is compared to the digital image data stored in the first buffer memory for generating activation signals when the occurrence of an event is detected and transmitting them to an external device; an image signal processor for image data processing the digital image delivered from the first comparator.

Front-end event detector and low-power camera system using thereof

An environment monitoring method and an apparatus therefor are provided. The environment monitoring apparatus includes a charging unit configured to charge power necessary for monitoring environments, a sensing unit configured to receive the power from the charging unit and to sense peripheral environments through a plurality of different sensors which are selected according to a request of a user, a controller configured to control settings of the sensing unit according to the peripheral environments; a communication unit configured to transmit the sensed information of the sensing unit to a server so that the server shares the sensed information with a plurality of smart devices, and a display unit configured to display the sensed information to the user and to display a notification according to the sensed information to the user.
