In Oct 2009, an "Internet Eyes" Site was introduced which might pay back members of the public to watch CCTV digicam images from their residences and report any crimes they witnessed. The internet site aimed to add "additional eyes" to cameras which could be insufficiently monitored. Civil liberties campaigners criticized The reasoning as "a distasteful and a worrying growth".
To shop and regulate the recorded footage, stability digicam systems employ recorders. There's two primary different types of recorders normally utilized:

By way of a process often known as total inside reflection, mild rays beamed into the fiber can propagate inside the core for excellent distances with remarkably บริษัท รังรอง จำกัด little attenuation, or reduction in intensity. The degree of attenuation above distance may differ based on the wavelength of the light also to the composition in the fiber.
A semiconductor laser emits mild by stimulated emission rather than spontaneous emission, which results in large output electric power (~a hundred mW) along with other Added benefits connected to the character of coherent light-weight. The output of the Rungrong laser is pretty directional, allowing large coupling effectiveness (~50%) into single-mode fiber.
