At present, the bottlenecks generally existed in alarm systems focused on false positives false negatives, alarm the alarm system is not intuitive, transferring three of instability. False positive false negative problem mainly occurs on the detector in alarm systems, after years of development, the "false positive" problems remain with infrared correlation product in hand, is considered to be the anti-theft alarm unavoidable technical difficulties. In fact, in these cases of false positives, there is now a new technology solution. Injection product technology is no longer a traditional analog, digital technology has made great improvement in accuracy of passive infrared detectors, resistance to white light, lightning, temperature compensation and auto-learning technology used, also make false error rate down to a range acceptable to the public.
Alarm not intuitive but also confused many users and manufacturers of problem with false positives false negatives of burglar alarm systems, pure voice and SMS alarm can't tell whether this is a misstatement or omission, nor understand the earthquake area the specific instance. Due to the current security host of technological breakthroughs were sluggishly, typically enterprise or select start from the detector to make up for the alarm system that not one of them. More common practice is the detectors and composite video, that the compound has various models:
First do a camera directly on the detector, and when a warning is encountered directly photographed or video is transmitted to monitors; the second is camera detector linkage, the detector itself does not come with the camera, only output port; the third is detector comes with digital cameras and storage devices. Beyond alarm signal to the host when an alert occurs, their own video or pictures will be stored in the SD card in, and easy for customers to view; the fourth is the detector itself comes with camera and GSM module, alarm occurs when MMS can be sent directly to the end user.
