产品性能:
     采用美国进口红外传感器进行信号的探测、采集及温度补偿技术，微电流技术，工作稳定，性能可靠，带低电压显示，当电压低于5.0v时led会变红色提示，另可根据用户的不同需要，改变探测器的间隔时间，在正常使用情况下，一节9伏电池能用8个月以上（探测器上有一标有1、2、3字符的三叉针处为探测间隔时间选择，选2、3时间间隔为6秒，选1、2时间间隔为4.5分钟，此时间可根据用户要求调整，调整范围为4秒~5分钟）；可防小宠物、阳光等不稳定因素的干扰；外设电源开关（拔向下为“开”）。
  性能指标：
探测距离：8~12米（探测器正前方25℃）
探测范围：水平：120°垂直：60°
工作电压：9v
静态电流：≤45ua
工作电流：≤45ma　　
抗干扰性：
1、防小宠物干扰：
探测器安装在*的使用高度，对探测范围地面的小动物，不产生报警。
2、抗电磁波干扰：
          探测器的抗电磁波干扰特性符合gb10408中的4.6.1的要求，一般手机电磁干扰不会引起误报。
3、抗灯光干扰：
探测器在正常灵敏度的探测范围内，受到3m外h4卤素灯透过玻璃照射，不产生报警。
 性能指标：
          发射频率：315±0.075mhz
 发射功率：200~400mw           
 发射距离：≥500m（空旷地）
红外安装要求：
          红外探头只能安装在室内，其误报率与安装的位置有*关系。正确的安装位置应离地面2.0~2.2米；远离空调、冰箱、火炉等空气温度变化敏感的地方：红外探头应尽量安装在室内的角落以取得的探测范围探测范围内不得隔屏、家具、大型盆景或其他隔离物。红外探头应与室内的行走路线呈一定的角度，红外探头对于径向移动反应zui不敏感，而对于切向移动则zui为敏感，在现场选择合适的安装位置是避免红外探头误报、求得*检测灵敏度的极为重要的一环。
product performance : in the united states dedicated infrared sensors imports for signal detection, collection and temperature compensation technology, micro-current technology, stability, reliable performance, a low voltage revealed that when voltage of less than 5.0v red led will alert other users may be based on different needs, change detector intervals in the normal use cases, section 9 volts batteries used 8 months (detectors, a marked 1, 2, 3 characters of the proposed three-pronged needle department for detection interval timing, the two, three intervals of six seconds, the 1, 2 intervals for 4.5 minutes, this time can be adjusted based on user requirements, the scope for adjustment ~5 minutes four seconds);
to prevent small pets, sunshine, uncertainties interference; the external power switches (weight down to the "open"). performance indicators : detection distance : 8~12 metres (detectors are front 25 degrees) detection range : level : 120 meridian east vertical : 60 meridian east working voltage : 9v static currents : =45ua work currents : =45ma interference sexual : 1, and against small pets interference : detectors installed in the use of highly recommended to detect the scope of the small ground animals, not have reported to the police. 2, the anti - electromagnetic interference : detector meet gb10408 - electromagnetic interference characteristics of the 4.6.1 requirement, the general phone electromagnetic interference will not cause misstatement. 3, resisting interference lighting : detectors in the context of normal sensitivity detection by 3m, h4 halogen exposure through glass without warning. performance indicators : the launch frequency : 315+0.075mhz fired power : 200~400mw launch distance : =500m (open to) infrared installation requirements : infrared probe only installed in the room, the location of the installation and its misreporting rates have great relations. correct installation location should 2.0~2.2 metres from the ground;
away from the air-conditioning, refrigerators, stoves, air temperature changes sensitive places : infrared probe should be installed at the corner of the room to achieve optimal detection not within the scope of detection screens, furniture, or other separation from large bonsai. infrared probe with indoor routes of a certain perspective, infrared probe response to the least sensitive radial movement, and the cutting is the most sensitive to movements in the se-lection of suitable location to avoid installing infrared probe misstatement, seeking the best detection sensitivity extremely important.
