With the increasing floating population, the social security situation is becoming increasingly serious, grab burglary, robbery, incidence increased significantly, to the enormous loss of life and property. Currently Ministry of Public Security, Ministry of Construction asked smart residential district must have a Security System. Residential area is characterized by the user focus, capacity, unified security management, the district security system must meet the "safe, reliable, cost-effective, centralized management" principle. SZH Series Active Infrared Detector will be used in smart residential area and flexible security system is to meet the requirements of residential security systems.
Detector Main features
Optical system: use of dual-beam infrared transmissive piece with the transmitting and receiving technology, the composition of the two beams overlap the field of view, to effectively improve the stability of the product reliability.
Signal processing: high-gain frequency-selective amplification, the double signal identification, pulse width modulation processing.
Strong anti-interference: radio frequency interference on the outside and a strong light interference resilience.
SMT: Surface mount technology to perfect the performance of the whole (smaller).
Optical Proofing: IR Alignment test table (microamps table) from the fundamental solution to the infrared beam (not visible) light school problems. Close (10 meters) can be used adjust the light show.
Detection range: of 5 meters, 10 meters, 20 meters, 50 meters, 100 meters and so on.
Adjustable response time :40-800ms.
Detector in the practical application of systems engineering security
Active infrared detector system can be used in the security perimeter to prevent cell can also be used to house the security of the residents.
Residential security of the past is in the house to install a passive infrared detectors, magnetic switches, emergency buttons, alarm signal to the control center via the network connection, when the intruder entered the room when committing the crime, the alarm signal. With the social development and improvement of living standards, the current variety of residential quarters, a growing number of buildings used as a garage or storage room floor, second floor stay residents, while common at the intruder into the household mainly through the windows at home Therefore, prevention has become an urgent task windows, and past the windows is to install security fence, therefore the first choice for residential security against active infrared detector detector should be around the second floor in the building and installed between the bottom of active infrared detectors, alarm signal through the network into the control center. When an intruder attempts to climb into the room through the window (when not enter the room), the active infrared detector alarm signal is generated, so that the family owners and a security control center to prepare ahead of time, security personnel can be very abundant in the scene to handle the case hair event.
The active infrared detectors based around the prevention of residential, has outstanding advantages:
24 hours deployment alert: alarm detector installed inside the house, at home or at night when the host window, the alarm system should not be deployed into the state, but also easily lead to false positives. If indeed the police, this time a thief has entered the room, to the tenants has caused mental or financial losses that may arise serious unexpected serious incidents. However, in the residential installation of active infrared detectors around, whether someone in the family or close windows or no windows, can implement security alert, and can advance invaders and take preventive measures.
System safety and reliability: If a district average household with four passive infrared detectors and four magnetic switches, if an average of 36 building blocks then the alarm on the address should be 288, if a District has 10 buildings with room then this plot should be 2880 on the alarm address, address of such a system alarm over the corresponding false positive rate was high.
If the above residential use of the system, then a building, only to install the 20 or so active infrared detector (alarm number Address decision by the house's appearance), if the district has 10 buildings with rooms, then alarm address should be 200 or so, compared to the system can reduce the alarm address 2680, the corresponding false positive rate of 93% reduction. This shows that the system is economical and reliable, and easier to property management.
Easy to use: the home security alarm system within the residential owners must be implemented promptly deployed, disarm, encounter an even greater worry for the elderly or children. While the active infrared detector deployed, the 24 hours alert, unified management of security personnel control center, home owners have no need to worry about things. Active infrared detectors in residential security system, currently in Zhejiang, Jiangsu and other regions have gradually extended the pilot and is well received by residents, property managers and relevant leaders and experts welcome and praise.
