Introduction:

AK-W3885 is one model of the Aithink mid-long distance series laser night vision device.Integrated multiple industry-leading technology and our company patents,it enjoys huge technical advantages in market and can be widely used in mid-long distance stabilized or moving monitoring.

The night vision distance is 500m in the compley lightless environment.They are small-size,light and user-friendly operation.With many leading patents of Aithink,they have realized the full time monitoring in army border,police anti-smuggling,marine fisheries,forest fire prevention,safe city,oil fields,factories,airports,railway station,docks,etc.,?and it can be great substitute of the traditional infrared ones.

Features:

With 22X optical zoom,laser output power:8W,Full-screen clear image range is 0-500m in the complete lightless environment.

Laser light spot saving patent technologies.Light spot can be user-defined and save in memory.(Patent)

HPLM laser mirror assembly ensures prefect optical axis alignment.

Adopting multiple leading technologies,mainly FTIS,ATPC,high-efficiency and precision constant circuit design to ensure long life of the laser.

Military A grade big power laser,adopting BRP the homogenization technology,laser expected life is above 20,000 hrs.

Synchronized zoom function,laser angle can automatically adapt to FOV without manual operation.(Patent)

2D optical axis adjustment mechanism facilitates users to calibrate the optical axis.

With images high-speed focus algorithms design,it solves dark night focus problem.

Adopting Dynamic Inligent hot-pixel technology,reduce the image noise and have better image.

Surge&Lightning protection function,the effective lightning range is 2500VA.

Built-in Chinese and English menu,Multi-language menu optional.

PTZ location info display function(latitude and longitude)

With 128 precise positions preset,4 tour groups,and pattern scan and lateral scan function.

360°horizontal direction rotation,90°~-90 vertical direction rotation,all-positions monitor.

Timing function.It can be preset the timing on PTZ and camera to execute user order.

Integrated wiper and ,it can remote control to clean lens and disperse fog.
