D1 image quality requirements Can save half of the image.
Solution: 6,7,8,9 four point four of D1 through a Video Server Connected to the monitoring center, the purpose and the rest of points in a compatible, able to control the software in a 9 camera.
Three cameras as 3,4,5 and the monitoring center can not be visual Bottom, but can and 2 video cameras, we use a bit of the four-point solution to point the camera at the 2nd Department set base station, monitoring center set to a remote site.
No.
1,2-camera through the roof of another bridge base station receiver.
Monitoring center roof with a 12dbi omni antenna and a 14dbi antenna, 1 camera with 24dbi directional antenna, 2 points, and 14dbi antenna with 12dbi.
1-5 control points using the server + bridge + video + camera transmission antenna.

System Overview Mine Video Surveillance , Mine monitoring, wireless monitoring mining, coal wireless video surveillance, remote monitoring system mines, coal mines as one of high-risk industries, Security Production is always top priority. As the coal mining areas complex, underground operations from the ground, terrain, poor environment, so prone to accidents, work on underground mine safety video surveillance is an important part of the production. However, a number of coal used in the current video surveillance systems are basically the early analog (CCTV) or number ( DVR ) Monitoring, performance and stability is not high, difficult to maintain, can not be achieved more control centers and multi-level monitoring and management, not suitable for the current authorities of the coal mine safety production supervision and management requirements. As the network Technology And computer technology, based on TCP / IP protocol of the IP network is widely spread application. The completion of high-speed broadband backbone and regional rapid development of high-speed access systems, and promote a variety of IP-based video communication applications. Therefore, the introduction of coal mine safety monitoring system of modern network video surveillance system has become a trend. Another wireless network video surveillance system for remote monitoring provides new ideas and more room to achieve a point-based streaming media , multipoint, multi-to-multipoint multicast remote real-time coding (radio) and monitoring, remote control camera functions
Wireless network video surveillance system for remote monitoring to provide a new and wider concept of space and streaming media-based point to point, multipoint, multi-to-multipoint multicast remote real-time encoding (radio) and monitoring, remote control camera functions. Wireless video surveillance system has a powerful user management features, good compatibility, easy scalability, distributed management and many other advantages, can fully replace traditional analog CCTV systems and digital DVR systems, and more, more within the industry to create and inspire a new application model.
System Overview 2, system Front-end (monitoring points): Camera (explosion-proof camera), video server (which can be accessed cameras, smoke system, infrared alarm system, methane detection system, audio, etc.). If you need wireless transmission, but also select the Wireless Bridge.
Back end (control center): a computer server. If wireless, wireless bridge need to set up. For TV wall control is required decoder.
3, the system works: Front-end server to use video cameras, infrared alarm, smoke detector, etc. into a digital signal, based on TCP / IP transmission control protocol in the network. This can be achieved as long as there is network connectivity remote monitoring. Coal-based regional network development
incomplete, need set up their own network. Optical fiber or microwave can be used to build the net. As the fiber cost is too high, it is recommended to build the net using wireless bridges.
Back through the computer monitor directly to the various points of the site conditions, by increasing the voice gateway can implement and monitor real-time phone fax contact point! If you need the TV on the wall, given the increase in decoder can!
4, the system summary:
The system is a simple networking program, usually only need to add the video server and wireless bridges can transform the existing analog network. Will not result in waste of the original network.
A Home Video Surveillance System
Protecting your home has become more a concern for many people these days. Many people are still installing home security systems. Others are choosing to install home video surveillance systems for the benefits that they offer that other systems do not.
One benefit of this type of system is that you can record everything that is going on around your home. This means that if someone was to try and break-in, or did break-in, you would have a video image of the person(s) who committed the crime. This will help when it comes to prosecuting the criminals that are caught. Another great benefit is that many can be viewed from remote locations over the internet. This is a great way to continue watching out for your home even while you are away.
This type of system is fairly easy to use too. Once it is install you simply turn the cameras on when you are leaving or whenever you want it on.
Some systems even have motor detector sensors which will activate the cameras any time movement is picked up by the sensor. You can use this system with a security system as well.
The cost for these types of systems vary although you should expect to pay at least a couple thousand dollars for one. The higher technology systems, such as the motion detector sensors, will cost even more. However knowing that your home is safe and that you can catch the perpetrator in the event of a break-in is well worth the cost of the system.
Spy Pen ? Real-Time Audio And Video Transmission
Spy pen is the device you have dreamed of so long! The spy pen transmits video and audio information in a real-time mode. It is the smallest full-function digital video recorder (DVR) ever, combining the function of an ordinary pen. Therefore, the spy pen enables you to record audio and video in a real-time operation mode under cover of writing an essay or anything that suits better.
The spy pen can be useful not only for secret agents, but for many other those who need someone’s hidden assistance organized in a highly technological way. The spy pen is irreplaceable while taking hard exams, at negotiations, while keeping somebody under covert surveillance or in any other situation when it is urgently important to transfer any kind of audio/video information secretly. Your boss is constantly showing the signs of sexual harassment? Or someone is blackmailing you? Or you want to show the police someone’s lawlessness? Use a spy pen then! No one will even get a hint that you are doing anything else but taking notes.
How does the spy pen work? Almost as simple as an ordinary pen! It functions as a video/audio recorder and then transfers these data to a signal amplifier, which is a part of a spy-pen set. The receiver, in its turn, transmits the files to your partner’s computer in a real-time mode. A special program will let your friend see the recorded information on his or her computer and, certainly, an installation CD is included in set. This simple scheme makes it possible to transmit data up to a distance of 25 metres! Just click an upper button of the spy pen and that will turn it on. Then click an on/off button of the amplifier and wait until two gadgets connect. Now all the recorded files will automatically get to your partner’s computer! If you need to transfer data for a distance over 25 metres – then you need a second amplifier. The only difference in this process-message model is in the fact that you will have to wait until three gadgets get connected – and that’s it!
The spy pen is not a ‘hello’ from the future. It is today’s reality and there is only one thing that can make it even more efficient and better: a spy earpiece. While using them together you will see how technology makes your success not only possible but also inevitable. How? You record audio and video information, your partner sees and hears it and if conditions demand some changes – gives you some instructions that you hear in your covert earphone! Such mutual invisible communication makes you fully armed with thorough knowledge what to do next.
Sometimes one can feel completely defenseless in cases when there is only one thought left: “If only I could record it! If only I could show it to someone else! If only it could be made public…” Already today, the spy pen can make it for you easily!
