Remote Internet Video Surveillance Program of Tax Offices of the National Taxation Bureau

Remote Internet Video Surveillance Program of Tax Offices of the National Taxation Bureau

(1) Remote online video surveillance of the tax offices of the National Taxation Bureau;

(2) The tax office of each branch bureau arranges two monitoring points. The collected video signals are converted from analog signals to digital signals by video servo equipment, and are transmitted on Ethernet using UDP or TCP protocol. The signal is transmitted to the superior management center;

(3) And set up a central monitoring and management system to receive the video signals from various monitoring sites, and manage and control. Monitor, record, store and playback video, and control PTZ and camera lens.

(4) Set up external network outlets for leaders to monitor at any time under the internal and external networks.


Equipment composition
DVS-102 dual-channel network video server

Front video part (camera can be selected as a gun, hemisphere or integrated smart dome, PTZ / lens, cloud mirror decoder, etc.)

Intelligent video integrator (optional equipment, expand and integrate multi-channel video)

System monitoring software

Monitor PC Server, video encoder + monitor or networked PC
System functions

1. Multi-channel monitoring: the monitoring center can arbitrarily select 1, 4, 9, 16 monitoring points in the global monitoring area to perform real-time monitoring at the same time
2. Video recording: using hard disk to record multiple monitoring signals in real time
3. Video retrieval and playback
4. PTZ and lens control: the camera adopts a fixed method of fixed focal length and fixed direction. In the place where the illuminance changes greatly, an automatic iris lens should be selected and equipped with a protective cover
5. Multi-level user password management: implement user level management, users at different levels have different operation rights, improve system security.
6. Other data access functions

7. Log management function
8. Remote monitoring and recording: In the private network, PCs can remotely monitor or record video via Ethernet, and can also choose special video encoders and traditional monitors for monitoring. At the same time, they can support Internet remote monitoring through VPN or DDNS technology. .

Introduction of main control equipment
DVS-102 four-way network video server is an embedded video processing, control and transmission equipment. Its core is a RISC embedded computer running a real-time operating system and a high-performance video DSP. The input video is digitally compressed and handed over to the embedded computer. Users on the network can directly use the browser or other special support software to observe the image of the remote camera. Super users can also set up, operate and control the PTZ camera on the video server through the network. Lens etc.
The system features adopt PSOS embedded real-time operating system (RTOS) to solve the virus and crash problems of PC

Supports 1-4 channels of full real-time audio and video collection, compression, and transmission.

Portable case with mounting parts for easy construction

It can be conveniently browsed, recorded, retrieved and played back on the PC through dedicated client software

Audio compression adopts ADPCM / G.729 algorithm for compression

Video compression adopts MPEG4 algorithm with optional picture quality

Support external alarm detection

Support the function of controlling front-end PTZ and lens

Password management, safe and reliable
