Traditional security products include access control, infrared alarm, smoke sensor, camera and video monitoring, etc. The usual alarm center transmits the information of the front end of the alarm (smoke sensor, infrared ...) to the center through the telephone line dial, the biggest problem is not knowing Whether the alarm is a correct alarm or a false alarm can only be viewed on site. Most camera video surveillance (CCTV) is connected to the monitoring center through a video cable (optical fiber plus optical terminal), the display (TV) and stored in the hard disk video recorder. In addition to the staff on duty, the owner and superior supervisor cannot immediately understand the truth. The embedded network video server can solve the above two problems. It passes the alarm signal to the embedded server through the alarm port or 232/485 data port, at the same time, the camera is directed to the alarm-related area, and connected to the embedded server, these alarms and video multimedia information can be transmitted to the alarm via the network On the mobile phone of the center and the owner, the duty personnel, leaders and owners of the alarm center can immediately view the local video after receiving the alarm information from the computer terminal or the mobile phone terminal to understand the real situation of the alarm. The traditional installed camera video surveillance (CCTV) is connected to the embedded video server and will be upgraded to a digital third-generation network video surveillance on the network. Duty personnel, leaders and owners can monitor anytime and anywhere. A key technical device for digital information flow, the embedded network video server has the following technical characteristics: 1. It has the core functions of multimedia information processing, including digitizing and compressing the video of the camera into a small digital stream, digitally compressing and encoding the collected audio, and also accepting digital audio from the network, decompressing and playing to achieve monitoring and intercom ; With 232 and 485 control commands and various sensor digital acquisition access communication, and alarm input and output communication, the network video server package these video, audio, digital command signals and data acquisition and alarm information Other communication nodes and terminals of the network. Therefore, the improvement of the video and audio processing capabilities of the embedded network video server, the realization of high-definition video compression, and its use of very little bandwidth and storage resources will become the key technology of digital information flow. 2. It has a powerful communication service function and can realize interconnection with various network nodes and terminals according to the "uniform communication" and NGN communication protocols. 3. It has a powerful wired network and wireless network expansion access function. It can be connected to a wireless local area network (WLAN, WiFi) and 3G broadband wireless through the USB port. To achieve wired and wireless switching, dual network communication is also possible. Transmission, expanding the communication security channel, and achieving ubiquitous network access. 4. The embedded server can be equipped with built-in and plug-in external storage such as small hard disk, flash disk (U disk and SD card, etc.), it can store multimedia information for backup and information sharing, equivalent to Nodes and storage servers for information content on the network. 5. The server has high information security and stability. It is embedded in the device with a Linux kernel and is not subject to any virus. 6. Multi-video resolution and code stream: Select the code stream and the corresponding video resolution (resolution) according to the characteristics of the network. If the mobile phone network is relatively narrow, adaptive low resolution and low code stream should be selected.
Modular design of Optical Cable Cross Connection Cabinet(FDH,FOCC) provides the largest flexibility; satisfy the needs of the present and future development. The body using the stainless steel and surface using electrostatic spray so it has good corrosion resistance and anti-aging function, the wind protection class of the body achieves the IP66 level. The effect of defense dewing is excellent. The module tray can spin out of 90 degrees around the axis in the left front, and the bevel of the adapters within the module takes on 30 degrees. The clip-locked installation ensures the bending radius of the fiber directly and prevents the eyes from injury. Weld disk can spin out of 90 degrees, and then draw out, so it is convenient to construction, and also convenient to expansion and maintenance. Have doors in the front and back, have ample space for cabling, convenient to operation and maintenance. Have reliable device for fastness, peeling and grounding of the optical cables. Insulation resistance between high voltage protection earth and box20,000MΩ /500V (DC)
Communication Optical Cable Cross Connection Cabinet is interface equipment to contact trunk optical cable and wiring cable. It is compose of box, inside structure, optical fiber connector and some accessories. The function is to connect, store, dispatch and enlarge optical fiber. The material of box is cold-roll steel sheets, SMC fiber strengthen unsaturated polyester or stainless steel material. It has high resist destroy capacity, high strength, safety and stability. It has the device to bring optical cable, fix and protect. It has optical fiber termination device which could easy to splice, fix and maintain the optical cable fiber and optical cable fiber/optical fiber pigtail. At the same time, it has more space to store the surplus optical cable and fiber. Through the optical fiber connector, it could dispatch the fiber serial number of optical cable and change the transmission system route rapidly and expediently.
