There are generally two types of night vision laser systems: active and passive. The active night vision system uses near-infrared light as the light source to illuminate the target, such as infrared LEDs, infrared lamps

The laser camera is equipped with a laser light source on the surveillance camera. The laser light adopts the uniform spot enhancement technology and the spot automatic focusing technology, which has the advantages of st

Night Vision Laser  | The characteristics and advantages of laser cameras are mainly reflected in several aspects: The first is the monitoring distance. Laser cameras can be divided into short-range laser cameras

The infrared range finders uses the principle that the reflection intensity of the infrared signal is different when it encounters an obstacle. In the rangefinder there are infrared signal transmitting and receiving diod

(1) Place the instrument First place the theodolite on the measuring station, after centering and leveling, install the rangefinder mainframe on the theodolite bracket, lock it with the connector fixing screw, insert the
