    Security cameras for your home have changed a lot in recent years, the changes have made the cameras more affordable and easy to use than ever before. Yes, a home security system company can install them for you but there have been leaps and bounds of progress since I've started installing cameras, very few of these new systems use the old coax and a power cable. Most of the new camera systems are wireless or use a Cat5e cable and connect to your computer, TV or recorder with ease. There is even one that creates a secure video network over the existing electrical wires and is very easy to do yourself.

    Let's start off by briefly going over the wiring of the older or should I say standard security cameras, these standard cameras that use a coax cable and a power cable are still available on the market today.

    Installing a BNC Connector.

    Installing a BNC connector is much like installing a connector for cable TV. There are basically three types of BNC connectors, one you simply twist on, the compression type and the other you assemble all the little pieces. I strongly recommend that you use the twist on type of connector, it's easy and no special tool is required. I'm not even going to bother going through everything that is involved in the jig saw puzzle model, and it's just not worth it.

    The process is simple, strip out the coax cable as pictured and twist the connector on until it is tightly secured. Doing it yourself is very easy.

    . The compression type connector is a good secure connector, the only down side is you will need a special compression tool to install the connector. . The wire strips out the same way, you just need to slip the connector on and use the tool to secure it.

    Connecting all the components of your home security camera system.

    Once all your cables are in place this is a fairly simple process, all your cameras go to the input of the switcher or multiplexer and video out goes to the recording device which than connects to a monitor or TV. The key thing to remember is that different cameras require different voltages, 12VDC, 24VDC, 24VAC, 120V. It is imperative that you use a power supply that is the correct voltage and can supply enough current for the number of cameras you install. The camera you purchase should have all the power requirements in its documentation. It is also important to use the correct size cable for the power, the further the camera is away from the power supply the larger the size of the cable required. In your typical home 18g or 16g should be good enough unless you have cable runs of 2 or 3 hundred feet.

    These days you can get wireless wifi cameras, but keep in mind that usually means wireless internet connection. All cameras need some sort of power to operate, unless you purchase battery powered cameras you will need to supply power to the camera. There are also IP cameras that only require an Ethernet cable and gets power from a POE switch.
