The induction distance is general, the Angle is relatively small, and it is greatly affected by the environment, temperature, dust and so on. In the case of 37 degrees, the induction distance will be shortened. Detection of infrared sensor head needs to be exposed, which is inconvenient to install. The radar switch is an ideal replacement product for infrared switch.
Radar surveillance systems are ideal for protecting high-risk power stations, prisons, military installations, and high-risk industrial areas. Radar planes for fence products sensitivity adjustment can be set at the scene, can set the prisoner by fastest speed and the speed of the slowest through, radar monitoring system can prevent the prisoner with high ladder over the wall, can request product is suitable for the climate environment is bad, for the wind, the snow in winter, the summer sun, has a good adaptability, lower the rate of false positives.
Prison perimeter protection distance in the radar performance indicators can work to work ° C temperature range all-weather and high resistance to damage resistant casing design radio frequency interference and electromagnetic interference or IP65 standard (waterproof, dustproof design power lost protection and use of standby power supply can be easy to install and adjust the Settings; Multi-level sensitivity adjustment is used to protect the area with high degree of safety.
The sensing distance is related to the sound emitted by the object. When the surrounding environment is very noisy, the light may be on all the time. If it is too quiet, it may not be triggered. The microphone head needs to be exposed. If used in long-term workplace, lamp bead attenuation is relatively large.
Due to the Radar signal frequency is high, easy to evade name is complex, the larger environment noise, easy to obtain reliable results, centimetric wave (such as 24 GHZ) gradually replace traditional testing equipment in the field of civilian consumer solutions (sensor), get the opportunity to popularize and apply, such as intelligent lighting control, underground garage vehicle detection, speed detection, motion detection, etc.
The latest radar and radio systems are a complex collection of highly integrated digital, analog, and rf/microwave electronics controlled and analyzed by advanced computer systems (see figure 5).SDR technology, which underpins most modern radar, is also used in wi-fi routers, smart phones, cars and cellular base stations .The differences between aerospace and defense radars and modern commercial radios lie in the complexity, bandwidth, and power of rf and digital electronic devices, as well as in the size and power processing capabilities of antennas.
