Chavi International Is A Direct Supplier Of Utp Video Transceiver (video Balun)

Let us start with cameras first. Work out the places where you want to put up cameras in your property (Office, Home, Factory, Warehouse). Put them in to scaled drawings. If cameras are within the range of 200 feet from each other then they will require one DVR to record and process the signals from different cameras and for cameras placed in different building and distance between them is more than 300 foots then we will require two or more DVRs depending upon the distance between them. These DVRs are networked together with your computer using network port. Cameras should be placed at entrance and at places which don’t have easy visibility. Cameras should overlook places which are having valuables. One stand alone DVR can control signals from 32 cameras.

Many people determine after buying a system that they need more cameras. A good rule to use when buying DVR is that is you are only using 75% of its capacity. Buy a 4 channel DVR if you need three cameras or a 8 channel DVR if you are going to use 6 cameras. Under normal circumstances a wired DVR and camera system should stay within 150 to 300 feet of each other, meaning with two cameras in different directions you can cover 300 to 600 feet. A low power wireless system works very well up to 1500 feet, while a high power transmitter will comfortably work at 3000 to 6000 feet from the DVR. If you are using different building with walls and distance being a factor with the wiring or reception, consider two DVRs and they can be connect to any computer port in your network. Another factor is the power supplying the DVR. Having a 2nd DVR on a different circuit or electrical grid can increase security in the event that wires are cut or power turned off by the burglar. If your situation calls for more spacing between cameras and the DVR, talk to your supplier and there are things like changing the wire and cable that can increase distance. Even though most systems advertise longer distance, I am being conservative as type of cable and composition of walls make a big difference in wired or wireless camera reception range.

Cameras have to be weather proof if they are to be used on external parts of the buildings. For total darkness infrared camera has be to be used. Camera has to be such that they are not visible to passerby. In areas where you want camera visibility to deter crime, use professional CCTV cameras located in outdoor enclosures. These professional cameras have a variety of features to include auto gain, auto iris and back light compensation. Also you can get a wide-angle or zoom lens that can be controlled remotely through your DVR.

If you find that you need a combination of wired and wireless cameras, than you can mix wired and wireless cameras with your DVR. If however you really only need one camera, consider a hidden camera or hidden DVR camera sometimes called a nanny cam. These hidden cameras are built into common objects found in the home or business. These cameras can be built into exit signs, clocks, mirrors, radios or air fresheners. Most of the objects used are fully operational. Also a hidden camera with internal DVR can easy be moved to any location and simply plugged in to operate.

Connectivity is our next goal. Do you want to set up a surveillance center in your business or just store the Video Balun on the DVR for viewing later? You also can send your video information over the internet and look at it on your laptop, PDA or smart phone. Today we have found that putting a DVR card in your computer to save money, instead of purchasing a stand-alone DVR, is not always the best idea. When you use your computer as a DVR you are susceptible to computer hacking or a virus and you must run your computer 24/7. Also you should run a separate external hard drive for recording the video. The security DVR is required to convert video signals to digital date so you can view or record this data. When using your video surveillance system to view the premises, but you have no need to record any video you can use a DVR USB that converts video signals to digital data to go to your computer, monitor or to a modem for the Internet. The DVR USB does not have a hard drive. The final option to go from video recording to viewing video data is the IP Camera. The IP camera has its own separate IP address and can be connected directly to your computer, monitor or modem for the Internet. Again the IP camera does not have a hard drive, but it does not require a stand-alone DVR.

In conclusion, determine the number and location of the cameras. Determine how you want to view the video signal and if you need to record it for later viewing. Then review complete systems available, and if they fulfill your needs, they can save you money with the complete video surveillance system when compared to purchasing individual components.
