Abstract: A surveillance method performed by a surveillance apparatus is provided. The surveillance method includes determining whether an event has occurred based on detection data; in response to determining that the event has occurred based on the detection data, transmitting a first wireless communication to an outside of the surveillance apparatus by using a second communicator at a second frequency and switching a power-off state of a first communicator to a power-on state; and transmitting a second wireless communication, corresponding to the event, to the outside by using the first communicator at a first frequency higher than the second frequency.

Abstract: An image processing apparatus includes an image processor and an encoder. The image processor enhances an edge of an input image, removes noise from the input image, synthesizes the edge-enhanced image and the noise-removed image, and removes a high frequency from the synthesized image. The encoder pre-encodes a downsized synthesized image, obtains a pre-bit rate of the pre-encoded image, sets a quantization parameter value based on a reference bit rate and the pre-bit rate, and compresses the high-frequency removed image based on the quantization parameter value.
