* 3G laser night vision surveillance system platform provisional overall presentation 3G wireless monitoring refers to the monitoring equipment (cameras) video signals via public wireless mobile communication network (3G network) transmission, to achieve timely distant scene viewed online, without time and geographical restrictions. With the accelerated pace of commercial 3G, 3G wireless network technology is also accelerating innovation, 3G wireless monitoring access device functionality and performance has also made a larger increase, 3G wireless monitoring will have a wider road applications. This system not only has 3g wireless monitoring functionality, but also at the same time according to the actual working conditions of the policemen reasonable combination of long-range laser night vision and long-range wireless control PTZ together, dispatched from the fundamental solution to the short distance, the night can not be dispatched with the background of the problem can not be adjusted dispatched direction. Better adapted to the needs of the criminal investigation and evidence gathering. II. System Components 1. 3g distance night vision laser machine 3. Special monitoring of computer terminals (optional) (a) 4. Auxiliary accessories equipment (a) a head tripod stand 1 set 1 set of hoop Toolbox 4 Several accessories III. Specific features and benefits of the system 1. The system with remote monitoring capabilities, without distance limitations, as long as there is around 3g network signal, can be used. 2. The system has long-range laser night vision, night vision laser machine distances up to 300 meters in the evening. Close split type laser night vision night vision up to 80 meters at night, which can be a good long-range surveillance, a fundamental solution to the night can not be dispatched and close surveillance is not hidden inflexible Question 3. The system has remote control of PTZ functions. Adjust the lens can be very good according to the direction of a moving target shooting with focal distance, thus expanding the scope of surveillance. 4. The system has a flexible emergency surveillance function, in the case of internal devices are equipped with high-capacity battery, fully charged long-distance night vision laser machine can work more than six hours, close split type laser night vision can work 10 hours above, while the background of special monitoring terminal can work more than 10 hours. Which can play a good role in an emergency. 5. The system is simple to use operating advantages, after the front-end surveillance installation Booted Simply connect the card on special monitoring terminal and open software. The software will automatically connect to the network environment automatically adjust frame rate, delay, without operator adjustments themselves according to their own network environment. 6. The system has high video transmission security, mainly in the following points:? We are point to point video surveillance is a major feature of the server is not required. (Server mode to make up for a static IP data flows easily be intercepted, and the server vulnerable defects) video data acquisition front-end is touched by the number of conversion? - Compression - Encryption manner. In monitoring terminal through decryption - decompression - show, RSA1024 bit high-strength encryption, more secure within a unique Unicom card, not connected to the external network, the back-end only with our special offer Unicom network card can view? the front end of the video, a better solution from the channel security issues? independent software module correspondence, that is all your modules can only be accessed by the software of your watch, your software can only access your own front-end module . ? In short, you want to access the front end of the module must have the following conditions: 1. have the front-end module corresponding software; 2 unique Unicom's network card, the card can not be ordinary; 7. The system has a video ?.? higher quality features screen size 360 ??* 288 Video frame rate: actual can reach 25 frames / second to 30 frames / sec signal is stable under normal circumstances the delay is less than 2 seconds 8. The system has the characteristics of low operating costs? ? When the generation of 3G traffic monitoring, when not monitored does not produce 3G traffic. That is, if the front is on, but the background of computer software is not open, do not produce 3G traffic. 9. The system has the characteristics of low construction costs? Reduce the servers, firewalls and other large hardware investment? Does not require specialized technical personnel for server systems
