Emergency Communication


Through installing 3/4G on-board video terminal server for lawenforcement vehicles, it could realize transmission audio video information andreal-time image. Effectively enhance the efficiency and transparency of onlinecommend during the process of law enforcement.


Our country's economyentered a stage of rapid development. Urban landscape is a most intuitive reflectionof city culture, the security and life safety of people could not lack the hardwork of public security department. Continuously improving of city securitymanagement ability requires modern equipment and civilized law enforcement, soas to effectively guarantee steady economic development and social order. How torealize fair, effective and transparent law enforcement, it needs both thepolice team building and the demand of the masses of the people and theharmonious society. Therefore, CCOM launched a public security monitoringcommand system solution scheme to help law enforcement ministry to conduct supervision,standardize law enforcement activities and deal with emergencies at the processof enforcement.


Solved problems

Law enforcement vehicles could use 3/4G video server at the scene of lawenforcement, first-time upload the real-time images to the servers. Then commendand dispatch personnel could visit server to immediately get information of lawenforcement scene and make direction through two way audio function.

Law enforcement vehicles could use 3/4G video server at the scene of lawenforcement, effectively record the situation of scene as to enhance thetransparency of law enforcement.


Solution scheme

The whole system isdivided into front-end subsystem, wireless transmission system, the monitoringcenter three parts.

1. The front-endsubsystem

Front-end subsystemincluding 3/4Gindividual video server (on-board 3 Gvideo server, or 3Gportable hard disk video recorder), cameras, intercom headset, etc. 3/4G video server as the core device, isresponsible for compressing and coding the acquisition of video image, thenupload to the monitoring center through 3/4Gnetwork, implement the remotewatching video.

The specific designsare as follow:

(1) Front-endsubsystem using the camera on the scene video acquisition.

(2) Camera connects with3/4 g video server throughshielding coaxial cable; collected images will be compressed and coded through3/4G network, and thenuploaded to the monitoring center.

(3) Wireless 3/4G server needs a 3G or 4GSIM card.

2.Wireless transmission system

Wireless transmissionsystem has RJ45 front-end ports, through the local IP address, can previouslyset 3G network video servercorresponding to the monitoring center position. Due to the particularity oflaw enforcement, they can use private network to make the equipment to receiveaudio and video data, through the wireless network (TDD-LTE, FDD-LTE EV-DO, TD-SCDMA,WCDMA, CDMA and EDGE) transmission in the private network.

3.monitoring center

In the monitoringcenter computer room, the monitoring center platform USES a server, andinstalls network video management platform software. According to thesituation, monitoring center will install the TV wall, through the networkvideo decoder to vehicle image decoding into TV signal, output to the TV wall.
