Store alarm system signal poor communication, how to solve the recent years, due shop alarm system user's signal communication link is not clear, when the alarm signal can not be uploaded normally occurs when circumstances occur thefts user. As in 2005, there are Internet users theft occurred at the center of the signal did not perform a show that night, "arming" of its anti-theft alarm system operations. By understanding the art center, and access to the event recorded its burglar alarm system stored, confirm that the user is indeed the night was "arming" of its anti-theft alarm system operation, when the suspects entered the "zone" crime, the system also sent a warning signal, but the signal is not uploaded to the center, the center of the art when inspections at the user, telephone communication lines provided by the user burglar alarm control host communication are used in a normal state. Case analysis and solution is clear, the above-mentioned cases the problem is occurring on a communication line, center technical staff after repeated test trials, finally found the problem. It turned out that the telephone communication line before entering the alarm control host communication, also connected to a telephone, and then the door phone is not "hang up", resulting in the alarm control host communication communications links that enter in the suspects' Zone "when committing the crime, although the system sends an alarm signal, but due to the interruption of communications links, no alarm signal can be uploaded to the center in time. From this case can be drawn at the time of anti-theft alarm system construction, proper access method communication lines are: communication line first after entering the home burglar alarm control host communication, other communication device user should be connected thereafter, so as to effectively prevent the user equipment failure due to the interruption caused by the communication link. Second proposal shops network alarm users to choose products tend upload via GPRS and police intelligence confirmed with video equipment, so the above situation can be avoided. www.baojingxitong.com 18719449656
