Bnc Jack
what kind of signal does a BNC camera output?
A security camera outputs a high resolution image through a BNC connector. What kind of signal is it? What can read that signal? Using an adapter to make the BNC into an RCA jack won’t work will it?
I would suggest going direct to a DVR or monitor.
but you can buy adapters but like all adapters you will lose image quality.
If you are looking at CCTV equipment here is an earlier post.
These brand manufacturers also have a complete line of CCTV cameras and DVR for any application from residential to military and stand behind there warranties.

Ascendent Technology Group ’s has a really good 4 camera package for around $500.00 and will sell direct if they don’t have a dealer in your area.

Not all CCTV equipment is created equal, in fact there are many options that offer varying performance take cars for example. In the world of CCTV you can find the equivalent of a $2,000 golf cart and a $350,000 Ferrari and everything in between. Both have 4 wheels but that’s where the similarities end, it’s under the hood that counts.
95% of all wireless cameras are compete junk and any wireless camera under $400 run on 1.2, 2.4GHZ or 5.8GHZ and wont offer encryption. This is bad for 2 reasons one the signal can easy be jammed, with a laptop you can actually hacked video feeds so a criminal can use it to spy and know a good time to target your business or home.
Just like any other consumer electronic in the end you get what you pay for. Most retailers and sellers make about a 40-80% profit margin, this is after costs like shipping and overhead. That means when you buy a product that costs $100.00 the manufacturer usually has only spent $30 to build it which simply means it’s not a good product and will probably have a working life of about 2 months. There is a reason these products are 1/10 of the price of good and reliable DVR brand names. The type of seller these products attract are online sellers (ebay) and will make profits margins as low as 3% which means they can’t afford to offer good service or allow for RMAs (returns). Cheap products are like disposable razors they are NOT designed to last for a long time and you will end up replacing them every 2 months.
Now some products can be made cheaply like ipod cases, screen protectors, and other simple products with no moving parts or electronics. DVRs need to be good quality as they run 24/7 (20X more than the average electronic device) and process anywhere from 30-480 frames per second which in a year is over 15 billion images, and a good DVR should last 3-5 years.
A true DVR and camera require years of research and development to facilitate the seamless integration of both the hardware and software. DVRs are highly complex systems that must run 24/7, processing millions of images per day and are one of the few products that can’t be made both well and cheaply. Cheap and inexpensive products like Q-see, X10, Swan, Lorex, and other low grade DVR’s and cameras sold by Tiger Direct, Newegg, radio shack Sams Club, are not used by any security professional and should only be used by hobbyists.
To be honest the “frys” productsare Garbage and are not used by anyone who has worked with CCTV or security products. I They are poor quality especially for IR cameras, due to low quality material, low S/N ratio, and low grade CCD image chips.
Also as far as night vision or IR cameras go most do not give good images in the dark. Many companies claim good night vision but there are only a handful of brands who give night vision over 30 feet out doors. normally if a cameras is rated 150 feet of IR it will give you ok images at 30 feet at night and good images at about 20 if rated for 60 feet you might get 15 indoors and will be useless outdoors.
Now one option for wireless is using commercial IP radios which are basically wireless routers on steroids and can offer distances up to 40km of wireless with military encryption, this is not a cheap solution but neither is digging a trench. using these radios not only give you a security infrastructure but also communications infrastructures as well for internet and other purposes (LAN network)
Good radio company

now in order to use this wireless network to distribute video you need to buy IP cameras which are similar to IP cameras only they transmit video over networks instead of a cable.
The company I recommend for CCTV products is Ascendent Technology Group they have a large product line and offer better products then Pelco Honeywell and Bosch and are about %20 cheaper and in my opinion have the best IR outdoor camera line up.
For an IP I recommend uses Ascendent`s IP servers that have a hard rive built in which does 3 things. Allows you use any analog camera and convert it into an IP addressable server. Allows you to distribute video over the network and has an HDD in it so that if the network goes don’t or your NRV (network video recorder) goes down or gets stolen you have data redundancy. some companies use SD

A Bit on Video Cables..
So in attempting to connect my TV in the best way possible, it was necessary to do a bit of research into video cabling and the various qualities of each method of connection.
S-Video stands for “separated-video”. This is the next step up from composite video.
Interestingly here, we see that the bandwidth (or the volume of data) of an S-Video cable is the same as for a composite video cable. The difference is that S-Video reduces dot crawl, hanging dots, and crawling edges that appear on the vertical and horizontal edges of some colored objects in the picture. Dot crawl, hanging dots, and others are technological terminology for various odd effects that can happen in signal transfer that skew, distort, or otherwise make the picture worse.
S-Video works basically by separating the color information (Chrominance) from the brightness (Luminance). By doing this, it reduces things like color bleeding and dot crawl and greatly increases the general clarity and sharpness of the picture. The reason that this is so is that televisions are designed to display separate Luminance (Y) and Chrominance (C) signals.
If you have the option to use S-Video, it is preferable to component cable any day. This technology will stay around for a while as it is still the best option for certain electronic components that have a video output yet do not yet support HDMI or Component Video. You can get a decent quality S-Video cable for less than $20.
See example – www.ewholesaleoutlet.com/product_info.php?products_id=4590
Component (not composite) Video [aka Analog Component Video; Y - Pb - Pr; red-green-blue]:
Uses a three jack cluster of wires with the ends color coded green, blue, and red.
Y-Pb-Pr, or what we nowadays refer to as component video or color difference video, was invented to simplify video electronics and reduce the overall bandwidth requirements for transmitting video compared with RGB. In practice it provides one luminance signal with full horizontal resolution and two color signals with reduced horizontal resolution.
Y = Luminance, Pb = Chrominance 1, Pr = Chrominance 2
From your DVD player or HDTV set top box to your TV, it is analog, thus its full name is properly “analog component video”.
Also referred to as Y, R-Y, B-Y or color difference video. Some DVD players label the green, blue, and red jacks Y, Cb, Cr .
This cable may be a bit more expensive but is worth the money. Remember you can get great deals online on these cables.
See Example – www.ewholesaleoutlet.com/product_info.php?products_id=1304
Composite Video [RCA or BNC] (aka “yellow-plug” video)
The old “AV” standard connector. I have had these for years, and used to use them with my Super NES. Fun retro stuff. The common RCA connector is color-coded Yellow for Composite video. This cable also came with a red and white audio cable, but we will not discuss that here. That’s for later.
The term “yellow-plug video” is recommended to help cut down on confusion between “composite” and “component” (which sound alike and are often confused).
See example here : www.ewholesaleoutlet.com/product_info.php?products_id=5573
And in case you are asking, “Where’s the HDMI?” don’t worry a breakdown of HDMI cabling is on its way.
SUMMARY:
The three types of standard video connections described in the following table give you three levels of video quality. Optimize your viewing experience by using the best connection available for your connected component. For example, if your DVD player supports a component video connection, connect the DVD player to your Plasma TV using component video instead of composite video or S-Video. Remember you can have an incredible TV and an incredible Blu-Ray video source but if you don’t have the proper connection between the two, you will completely lose quality. Use the best that you can for your connections. This in turn, will bring you a great theater and media experience.
