(2) second way: this type systematic mainly comprises single or multiple video sensors, special-purpose monitor server (control centre), display terminal.At supervision scene, set up one or more video sensors, by dedicated modulation demodulation techniques (for making operating distance far adopt 433MHz operating frequency) to monitor server (control centre) transmission monitoring information, monitor server (control centre) shows monitor message by Internet network to guardian's display terminal again, and display terminal can adopt desktop PC, panel computer or mobile phone.
Such surveillance have set up conveniently, monitoring range is large, monitor the advantage of distance.The weak point of its existence mainly contains: 1. modulation /demodulation tranmitting frequency will be through the audit approval of Wireless Management Committee; 2. Internet network need be installed by family; 3. monitor server (control centre) special designs, Financial cost is high.
(3) the third mode: this type systematic comprises single dedicated video transducer and display terminal, and wherein, video sensor is provided with SIM card, this video sensor passes through commercial mobile communication network to guardian's display terminal transmission monitoring information.
Such surveillance has the advantage of setting up conveniently, monitoring distance.The weak point of its existence mainly contains: 1. video sensor can only be erected at certain room, cannot implement to monitor to a plurality of rooms; 2. video sensor special designs, Financial cost is high.
In sum, can not long-distance transmissions when existing surveillance exists monitoring range wide, during long transmission distance, need apply for radio frequency or rely on the problem of Internet network, and inconvenience and the high problem of cost of setting up that exist more.How to improve the performance of existing surveillance, to realize, monitoring range is large, long transmission distance, with low cost, stable and reliable for performance, easy to install, the target that can popularize, and is current surveillance urgent problem.
