Problems solved by technology
[0006] The existing monitoring system including DVR and analog camera, or the existing monitoring system including NVR and digital camera, cannot support the access of digital camera and analog camera at the same time, in other words, existing DVR and existing NVR cannot realize the control of digital camera and analog camera at the same time
In order to realize the control of digital cameras and analog cameras, the existing monitoring system needs to include DVR and NVR at the same time, which not only increases the hardware cost, but also needs to control the DVR when controlling the analog cameras and digital cameras. The work with NVR also requires the DVR and NVR to control the work of the camera connected to it, which increases the complexity of control

The invention provides a monitoring device, a monitoring system and a monitoring method supporting hybrid access. The monitoring device supporting the hybrid access outputs a control instruction to at least one analogue video camera through an analogue channel, codes an analogue signal of audio and video data acquired through the analogue channel, and stores a digital signal of the coded audio and video data; and / or the monitoring device outputs the control instruction to at least one digital video camera through a network link, and acquires the digital signal of the audio and video data through the network link; and the monitoring device decodes the stored digital signal of the audio and video data or the digital signal of the audio and video data acquired through the network link according to a received play instruction, and outputs and displays the decoded audio and video data. By the monitoring device, the monitoring system and the monitoring method, hardware cost and control complexity can be decreased under the condition of controlling the digital video camera and analogue video camera accessing the system.
Description
technical field [0001] The invention relates to video monitoring technology, in particular to a monitoring device supporting hybrid access, the monitoring system and a monitoring method. Background technique [0002] figure 1 It is a structural schematic diagram of the existing monitoring system. Combine now figure 1 , to describe the structure of the existing monitoring system, as follows: [0003] An existing monitoring system includes: an analog camera 10 and a digital video recorder (Digital Video Recorder, DVR) 11 . Wherein, the analog camera 10 is used to collect audio and video data, and after processing the collected audio and video data, output an analog signal to the DVR11; the DVR11 is used to encode and store the received analog signal, for example, video data and / or audio data to record and record, and the DVR 11 controls the analog camera 10 to collect audio and video data according to externally input instructions. The analog camera 10 and DVR11 in the ex...
