1、 Preface:

Firefighters carry wireless digital image transmission equipment, or the command car is equipped with wireless digital image transmission system to transmit the fire scene situation to the command center, so that the command center can timely grasp the fire situation, organize and dispatch fire forces, improve the rapid response ability, and minimize the loss. It can also store the fire-fighting situation to facilitate future analysis and summary and improve combat capability.

Wireless CDMA / edge video server has been widely used in order to solve the demand that the front-end images can be sent back to the monitoring center in time.

Wireless CDMA / edge video server, using Unicom's CDMA network card or mobile edge network card, can transmit 1 ~ 4 channels of clear and coherent video, rather than a single still picture. In this way, the personnel on duty in the monitoring center can see the timely video through the network; the leaders can also watch the video through the mobile phone Internet, and guide the rescue and disaster relief work at any time and anywhere.

3、 Principle of monitoring image:

4、 Vehicle mounted monitoring front end:

 the local video viewing and control function in the vehicle; the on-board display and control keyboard are used to enable police officers to control the camera orientation angle of the vehicle in the vehicle.

The commander can watch the front-end video in time through the PC network, also can display it on the TV wall on the decoder; he can also watch on the mobile phone through the wireless access system of the mobile phone. Even if he is on a business trip in the field, he can know what happened on the spot! He can control the rotation and stretching of the camera remotely. The video can be watched, and can also be stored, played back, retrieved and downloaded.

7、 System technical features:
