Tenda C60S is a brand new upgraded intelligent webcam, equipped with original million HD lens and top imaging sensor, 720P HD shooting, clear and delicate picture quality, and also supports infrared night vision function, infrared visible distance up to 10 meters; support QQ IoT, users can open the mobile phone QQ to monitor in real time, no need to install APP, easy to use; support capture cloud storage, QQ alarm advancement and other functions.
What is QQ IoT?
QQ IoT is an intelligent hardware open platform released by Tencent. It integrates the core functions of QQ account system, relationship chain and QQ message channel capability to realize the interconnection and interaction between users and devices and devices and devices. QQ IOT relies on the accumulation of Tencent's years of security experience, and has a stable and secure encryption transmission channel. All data of Tengda smart camera C60S is transmitted through QQ security encryption, which can protect the security of user information and prevent privacy leakage.
Tenda C60S usage
First, connect the power & add equipment
Camera C60S is connected to the power supply, open the mobile phone QQ, find “My Device†in “Contactâ€, click “Discover New Deviceâ€, and then click “Scan†to scan the QR code of the C60S body.
Second, configure wireless & device binding
After scanning the QR code, enter the password of the WiFi to be connected to in this interface. Then click "Next" to configure the sonic network, and finally click "Confirm Binding".
other functions
After the installation is complete, you can browse the monitored content.
Tenda C60S also has a "Buffalo B" function - motion detection alarm. When there is a moving object in the monitoring screen, it will trigger the motion detection alarm capture, and the captured image will be pushed to your QQ in real time.
Not only can you operate the device yourself, but you can also authorize QQ friends to use the device together. Click on the upper right corner of the device control interface to evoke the menu and select "Friends Authorization Management" (only authorized by the device owner).
FBT WDM - Fused Biconic Taper Wavelength Division Multiplex
A fusion taper type wavelength division multiplexer, comprising an input end cone, an output end cone, and a coupling area. The input end cone is located at one end of the coupling area, and the output end cone is located at the coupling area. At the other end of the zone, the input end cone includes an input arm and a backscatter arm, the output end cone includes a through arm and a coupling arm, and the optical power is input from the input arm of the input end cone through the The coupling zone is redistributed after coupling and output from the output end cone. A part of the optical power is output from the through arm and the other part is output from the coupling arm. The coupling zone includes two optical fibers, and the cladding parts of the two optical fibers are mutually connected. Close, when pulling the taper, the two optical fibers are pulled in opposite directions but cannot move relative to each other. The two optical fibers are processed by a fusion taper device.
At present, the method of making FBT WDM in industry is to use a flame to heat and melt the fiber at a single point and then stretch it. The defect is that the heating area is too short, resulting in a short stretchable length (corresponding to the coupling length), and the fiber diameter is not small enough, so This limits the minimum channel spacing that this type of wavelength division multiplexer can achieve.
FBT WDM, also known as Fused Biconic Taper WDM and FBT WDM Splitter, along with LAN WDM Splitter, Filter WDM splitter, dense WDM splitter and coarse WDM splitter, are the most commonly used WDM device in construction of PON.
Further, the melting taper device is formed by two insulation bricks made of aluminum oxide fiber insulation material to form a cavity, and the high temperature heat source is provided by an electric heating wire made of molybdenum disilicide material, and the heating wire is located In the heating tank, the heating temperature is adjusted by adjusting the voltage at both ends of the electrodes connected to it, the optical fiber passes over the heating wire, and the taper speed is adjusted by changing the rotation speed of the programmable stepping motor driver.
Further, the two optical fibers are fused and tapered in the fusion tapering device, one of which is used as the input power of the input arm, and the other is used as the coupling arm fiber. After the tapering length reaches a certain distance, the two fibers are coupled, and the optical power is Continuously couple into the coupling arm fiber, continue to taper, and the optical power is repeatedly and alternately coupled in the two fibers.
