Product introduction
 
   Daaotimes laser correlation alerter with invisible light 980 nm wavelength laser technology, easily concealed protection, the shape of the column makes products could vertical installed on the wall  or be installed in a tilting Angle of 90 degrees, which according to the characteristics of the building and security requirements. the installation key point is to post the basis fixed and no shift or shaking.Strong penetrating power of laser, very low rate of false positives, far prevent distance makes laser beam do not like radio waves, infrared light that  can be  influenced by the background light and interference (also does not affect product performance in the hot sun protection).the detection range can be adjusted from 0 to 1000 meters according to the requirement.Products elegant appearance, convenient installation, good waterproof performance is suitable for use in indoor, outdoor, outdoors, such as protection operation, can also support monitoring probe linkage lights, etc. 
Product scope
 
       Mainly aimed at the field, outdoor and other areas, such as: height limit bridge, railway, subway, factories and mines enterprises, large oil field oil depot, wharf, libraries, Banks, power, museums, exhibition halls, schools, farms, alert at the airport, prison security and military stronghold, armory, border border on the need to focus on strengthening monitoring, prevention, security, security, border crossing, outdoor enclosures all environment, there are important items of shops and warehouses, etc., also USES in the home guard against theft and more safety guarantee.
