Our Sparklet Optic Fiber introduces a light diffusion technology that achieves brilliant and distinctive sparkling effect without any noticeable reduction in the intensity of the light throughout entire length of cable travel. The Fiber optic strands are encased in a flexible clear UV stabilized PVC jacket to create fiber tail bundles in a variety of diameters for different type of projects. These fibers are best suited for sparkling effects, neon like effects, decorative lighting, chandeliers, and light Sparkle Fiber Optic,Fiber Optic Strands,Fiber Lights,Sparkle Fiber Optic Cable Jiangxi Daishing POF Co.,Ltd , https://www.opticfibrelight.com
Point-to-multipoint transmission means that multiple transmitters use one receiver to receive, and transmitters usually connect to the front camera. Do point-to-multipoint wireless monitoring system design must pay attention to the back end of a wireless bridge corresponding to the front-end device up to ten points, how to configure according to your transmission distance, camera bandwidth, your site environment to Decision. As for the receiver's angle can be determined according to your actual situation, the general angle of 30 degrees, 60 degrees, 90 degrees, 120 degrees, 180 degrees, 360 degrees and so on, the specific circumstances, please call Levin science and technology personnel for your design. If the distance from the transmitter to the receiver is relatively short and the transmission distance is less than 1000 meters, you can consider omnidirectional reception.
In addition, if you want to do point-to-multipoint transmission, must be within 10 km transmission distance, 10 km, including more than 10 km must use a one-to-one transmission to achieve wireless monitoring system, in order to ensure the stability of the wireless monitoring system.
When doing point-to-multipoint transmission , it is natural to consider the problem of transmission bandwidth. Then when using a camera, it is necessary to properly plan what pixel camera is appropriate. After all, wireless bridges have 150M and 300M bandwidth transmission links. If the pixels of the camera are too large, it will cause excessive transmission bandwidth and it will cause unstable transmission or even incomplete transmission.
How to achieve specific plans, please call the relevant technical staff to give you advice and guidance! The article comes from Levin technology wireless bridge monitoring equipment. . Com, please indicate, thank you!
Wireless bridge monitoring equipment has three modes: point-to-point transmission, point-to-multipoint transmission, and relay mode. Point-to-point is a one-to-one transmission mode. The front end can be a single camera, or multiple cameras can be transmitted through the switch and then use the point-to-point wireless bridge. In the relay mode, the wireless video signal is relayed by relaying in the case of an occlusion. The point-to-multipoint transmission mode is the most complicated in the wireless bridge monitoring system. The following Xiaobian will introduce you to the point-to-multipoint transmission considerations of wireless bridge monitoring equipment:
