1,2013 megapixel security camera, 2G wireless monitoring transmission methods including CDMA,2013 cctv camera pros, GSM two models. The two modes of the lower hardware cost, large coverage, transmission speed is slow,2013 battery operated cctv camera, the theoretical value of the transmission rate up to 153.6Kbps, in actual use can only reach
Chengdu Remote Control Technology Co. Ltd. 3G wireless monitoring and wireless monitoring WIFI difference between 3G wireless monitoring and wireless monitoring WIFI difference between
1, analog wireless monitoring is the wireless channel video signal directly modulated in 2.4G or 1G,2013 xbox wireless receiver driver windows 7, sent out by the antenna, the monitoring center to receive the wireless signal through the antenna, the wireless receiver to the original video signal, the monitoring of
3G wireless monitor
strictly speaking, divided into 2G and 3G in two ways; one is 2G die earlier test,2014 wireless monitor connector, another kind is the latest version of the 3G model test.
2, 3G wireless monitoring is the use of mobile (TD-SCDMA), telecommunications (CDMA2000 EVDO),2013 security cameras surveillance systems, China Unicom (WCDMA) technology of 3G access operators, since 09 years, the various operators to promote, many monitor manufacturers according to the R & D of related products. And the advantages of the 3G high speed download capacity,2014 cctv cameras kit, the ideal value transmission speed can reach 3Kbps~20Mbps, but because it is still in the promotion stage, so the transmission rate that has yet to be further research. 3G currently existing wireless bandwidth limited capacity, access Co., delay and other defects, the multi-user sharing, it is difficult to guarantee the wireless video monitoring rate and delay requirements, the main shortcoming or operators to charge flow Fei Taigao, general customers can not accept.
60~80Kbps. Because the video image bottom requires 512Kbps to smooth transmission, the speed can not reach the requirements of video. Therefore, in the wireless monitoring project, few manufacturers to choose. Another drawback is the operator for traffic fees are too high,2013 install security camera, every month,cctv camera surveillance, every year, will have a large fee. Only in a very remote, WIFI wireless devices do not to the case, will consider and have some money.
strictly speaking,top security cameras, WIFI wireless monitoring is divided into two ways; one is the simulation of wireless monitoring; another is the digital wireless monitoring.
