Security alarm monitoring system to people's lives , business interests and social security and other aspects of bringing security, saving manpower costs. The development of these high-tech devices are the crystallization of human wisdom , security system upgrade from human smart brain . However, multiple thefts from site survey can be learned, security alarm monitoring system also has weaknesses, in real life, crime prevention can not completely rely on technology . In the case of difficult to find, supermarket anti-theft devices monitor the overall layout problems, 180 video cameras actually did not get any trace of the night I do not know all the interior of the surveillance camera off or blind spot monitoring system exists , or monitoring system administrators failed to find police intelligence ? In the case of the supermarket entrances to focus on anti-theft devices , and infrared alarm device only from the second floor to the third floor staircase range work, it is not valid for the thief device . If the alarm monitoring equipment in the layout of the supermarket , in addition to import and export department , but in the main channel is also installed burglar alarm sensor or monitor with motion detection function using surveillance cameras are likely to find the thief . Motion detection technology , also known as motion detection , commonly used in unmanned video surveillance and automatic alarms, surveillance cameras through the acquisition in accordance with different frame image obtained by the CPU according to certain algorithms to calculate and compare the screen when there is a change , if any, people have gone through the lens is moved, calculation and comparison results show that the number will exceed the threshold and indicates the system can automatically make the appropriate alarm processing . Motion detection technology is the basis for motion detection recording technology has now been widely used in network cameras, car monitors lock , digital treasure patron saint , baby monitors , automatic samplers , since recognition access control and many other security equipment and facilities . Common motion detection system also allows users to freely set arm disarm time , detection sensitivity , detection area . When the trigger should be linked video , linkage alarm output, linkage to the corresponding camera preset position . It is precisely because the supermarket did not install this mobile detection equipment, but only in the import and export of infrared alarm device installed , leading to the counter to get Kwak phone without bar codes when commodity alarm system is not responding. In addition, monitoring anti-theft system supermarket in the details , there are drawbacks, such as window -ventilated place , although the gap is small , but it is also leading to the outside of the channel, supermarket layout at least let the system take place monitoring equipment . In short, supermarket security system is irrational anti-technology insufficient key point . Intelligent security monitoring system because of its high technical standards , so its price is more expensive , so many families Despair. So many companies began to develop new intelligent security system civilian areas . Compared to other systems, mobile video surveillance alarm system relatively inexpensive . Mobile video surveillance is through the user's mobile phone anytime, anywhere remote monitoring point to watch the video . The entire system is run based on the Internet . Currently mobile video surveillance has two modes , one is placed in specific locations by surveillance cameras and video images captured through video compression processing server upload to the Internet , and then transmitted to the monitoring center through the network video surveillance server and then use the mobile Internet the way , landing to the video monitoring server , access control list of resources , and finally select the desired viewing surveillance video . One is a direct point to point connection . Is the phone directly log on to the network camera or DVR / DVS, network camera directly read the audio and video frequency , then the mobile terminal for audio and video processing . When the user enters into the monitor screen, the remote can control PTZ camera angle adjustment , monitoring of key regional situation, and camera remote settings. The times to Kate mobile video surveillance alarm system that is point to point mode as an example . When the monitored area there are unusual circumstances , the server host starts the recording, one every three seconds to capture images and send the message to a designated phone . With the development of 3G networks , mobile video surveillance alarm system will also show its mettle in the field of home security .
