With the application of technologies such as network and cloud computing, video surveillance has also entered the era of network, high definition, and cloud computing. However, while the clarity and intelligence of video surveillance has increased, the need for 24/7 clear monitoring has not been effectively implemented.
At present, the infrared light source used by common infrared night vision cameras is mostly 850 nm LED light source, which is limited by light intensity and heat dissipation level, and it is difficult to achieve night vision fill light of 80 m or more. To this end, nighttime monitoring capabilities have become a shortcoming of traditional surveillance cameras. At the time when infrared night vision new technology is being called for a long time, Inspur Huaguang exerts its own advantages and launches a series of civilian laser night vision products, which effectively improves the all-weather monitoring capability of the camera and fills the blank of the localization market.
Inspur Huaguang has undertaken a number of national “863†and “973†projects, with strong R&D capabilities and leading semiconductor laser technology. In order to promote the transformation of laser technology achievements, the company is the first to introduce civilian laser night light products such as fixed-focus high-power laser fill light board and high-power external laser fill light, which fills the gap of large-angle and long-distance infrared fill light. The angle of nighttime fill light can cover from 100 meters to 300 meters, and can be customized according to customer needs.
Laser night vision products have the following advantages: 1. Using laser infrared fill light technology, can achieve night vision fill light of 200 meters or even kilometers, which is incomparable to LED infrared light source; 2. CCD and CMOS chip to 808nm laser sensitivity ratio The 850nm LED sensitivity is about 30% higher. Under the same illumination, the 808nm laser night vision imaging is clearer. 3. The semiconductor laser photoelectric conversion efficiency is 2-3 times that of the LED infrared, and the laser energy consumption is lower and the lifetime is longer.

In order to serve customers more accurately and improve customer satisfaction, Inspur Huaguang established the Intelligent Optoelectronics Division, which is responsible for the development and promotion of laser night vision products. The company pays attention to practical product research and development. With its long life and uniform spot characteristics, the products have passed the test of many partners and won unanimous praise. At the same time, the company pays attention to intellectual property protection, has applied for more than 10 patents for laser night vision fill light technology, and has built a perfect patent protection network. We can foresee that with excellent product performance and technical strength, Inspur Huaguang will become the first brand of laser night vision products.
PufangTech`s VHF radio modems operate in 136~174MHz and 220~240MHz frequency band. The VHF Radio Modem has an air data rates of 19200bps in 25kHz channel spacing and 9600bps in 12.5kHz.
Suitable to apply in data collecting, and VHF radio modems have been used to transmit voice and radio data since the middle of last century. This is one of the most efficient ways to communicate over miles away. A wider coverage is a different advantage belongs to VHF frequency from the others. VHF has 30 to 50 per cent larger range than UHF Radio Modem with the same carrier power.
