Abstract

The invention discloses a method and a device for realizing alarm inputs and outputs, which are used for expanding the alarm inputs of a digital video recorder (DVR). The alarm input method comprises a step of presetting at least one network alarm kit. The method also comprises the following steps that: the DVR respectively establishes network connection with the network alarm kits; the DVR logs on the connected network alarm kits and sets alarm input parameters of the network alarm kits; and the DVR receives alarm input information from the network alarm kits to carry out alarm processing. The invention solves the problem of limited regions and number of the alarm inputs and outputs of the DVR, so that the DVR can expand any number of alarm inputs and alarm outputs. Moreover, the networkalarm kits can be put at any position far away from the DVR through the network connection between the DVR and the network alarm kits.

Description

technical field [0001] The invention relates to the technical field of video surveillance, in particular to a method and device for realizing alarm input and output. Background technique [0002] Digital Video Recorder (DVR, Digital Video Recorder) is a computer system for image storage and processing, which has the functions of long-term video recording, recording, remote monitoring and control of image / voice. [0003] The DVR itself has a local alarm input and output, and the local alarm input and output interface is generally on the rear panel of the DVR. The number of local alarm inputs is generally 16, and the number of local alarm outputs is generally 4. Since the local alarm input and output need to be connected to the DVR through a connection line, there are at least the following problems: [0004] 1. The geographical distance between the alarm and the DVR is limited. When the alarm that is far away from the DVR needs to be connected to the DVR, the amount of wiri...
