Hierarchical monitoring system

Abstract

The invention discloses a hierarchical monitoring system. A power supply is connected to the first power supply port of the first network camera through a power line. The second power supply port andthe third power supply port of the first network camera are respectively connected to the first power supply port of the second network camera and the first power supply port of the third network camera. A monitoring center network switch is connected to the first network interface of the first network camera through a network line. The third network interface and the second network interface of the first network camera are respectively connected to the first network interface of the second network camera and the first network interface of the third network camera. The second network interfaceand / or the third network interface are electrically connected to a network accessory terminal. The monitoring center network switch is separately connected to a manager video monitor and a manager console. The network accessory terminal comprises at least a entrance guard, a microphone, a iris recognition device, a face recognition device, an intrusion alarm system, a network hard disk recorder,a network alarm and a network interphone.

Description

technical field [0001] The invention relates to the technical field of electronic information technology, and in particular provides a hierarchical monitoring system. Background technique [0002] For the installation of monitoring system engineering, the first difficulty lies in the wiring. If there are too many wires, it is necessary to install trough bridges and metal wire slots. Not only is the construction more difficult, but it also takes up most of the system deployment cost; Checking and wiring and subsequent repairs and maintenance also caused a lot of trouble; a good set of wiring will play a vital role in ensuring the normal and lasting operation of the entire system, and 85% of the faults in the project are caused by the wiring. If the construction of complex lines can be simplified, the number of lines can be changed to less, and the equipment can also be changed from more to less, and even the application of some equipment can be reduced, which may become the u...
