  How to Install a Digital CCTV System  
When finished with this article you will have a solid idea of how to install and program a digital and/or analog CCTV system for your home. I'm writing this article with a digital 8 camera system in mind, obviously you can adjust according to your specific needs. I've included a list of recommended brands/models for a mid-high range set-up.

BNC Connector It's time to mount the cameras in the enclosures. Take your camera/lens set-up to your first location. Slide out the camera rig and mount the bottom of the camera to the slide via the screw included in the enclosure packaging. Slide the camera back into the enclosure. Now, while your at the first camera, lets add the ends to our cables. First, peel or cut the electrical tape away from the two cables. Take your power cable and split about 4 inches of it down the middle. Now you just have to strip back each wire approximately a 1/2 an inch. Take your hot power wire and slide it into the (+) lead on the back of your camera, using a macro screwdriver to fasten it in place. Do the same for the ground wire. Once your power cable is finished, move on to the coax. This will require patience in order to get it right, and your going to need your crimp-on BNC connector and your pair of BNC crimps. Take the barrel piece of your BNC connector and slide it on to the cable, wide side at the top. Take your wire cutters and cut back about 3/4 inch of the outer casing, leaving only the center copper wire and protector. Then use your wire cutters to cut back about 1/2 an inch of the copper wire casing, leaving the bare copper wire. Snip the copper wire at an angle and slide your BNC over the exposed copper. Then it's as easy and pulling the barrel up the RG59 cable, over the end of the BNC connector and use your crimps to crimp it together. Do not connect this to the camera just yet.

*If your having a hard time making a good connection or just can't get the hang of making a BNC end, check the video link at the bottom of the post*

You know the drill, go ahead and mount the other seven cameras. Make sure to connect power and add you BNC end at each stop.

Samsung SHR-2082 DVR Let's go to the back-end of the system. Take the DVR out of it's packaging and position it where it belongs in your git-up. This step is very repetitive, but absolutely necessary. It's time to add our BNC connectors to all eight coax cables. Then it's time to splice our power wire and feed it into the power supply. When your connecting your power wire, make sure to keep (+) and ground wires uniform with their corresponding camera. Obviously, make sure your power supply isn't actually plugged in. All done? Let's move on!

GV-LCD3 Color LCD Portable Monitor Time to focus our cameras. Let's make sure our power is all connected both at the back-end and the camera. Go ahead and plug your power supply into the wall. Grab a left over piece of RG59, 3-6 feet will do, and throw BNC ends on both sides. This handy little cable will plug into our GV-LCD3 Color LCD Portable Monitor and then into the back of our cameras so we can focus them. So, BNC cable plugged into the top of the portable monitor and into the back of our first camera. Using the tiny thumb screws on the lens, begin to focus the camera to your liking. If it looks a little dark, go ahead and adjust the (BLC or Back Light Compensation) on the back of the camera. When focusing the camera be patient, it takes time to get it perfect. Once you have it perfect tighten the thumb screws carefully and pop the BNC cable off the back of your camera. Set your portable monitor down for a second and plug your designated BNC connector into the camera. Close and lock the enclose, making sure any excess wire is either zip ties to the frame or tucked away in the wall. One camera finished, seven more to go. Remember, this is critical in protecting your home and valuables, so really take your time and get a perfect picture.

So, you have eight cameras mounted, powered, focused and connected. You have 8 BNC connectors and a DVR at the back-end waiting to be attended to. Plug your BNC cables into the back of the DVR, starting at one ending at eight. Then take an extra piece of coaxial cable and throw BNC ends on it. Make sure this extra piece of cable is long enough to go from the DVR to the LCD monitor you plan on using for viewing footage. Once that cable is made, plug one end into the "out" on the DVR. The other end needs our BNC-to-RCA adapter, then plug the RCA into your LCD monitor. Plug your DVR and LCD monitor into the wall and power both of them up.

Finally Finished. Your nearly finished. It's only a matter of minutes before you see what real work you've accomplished. Your DVR will probably prompt you for a few general settings like, when to record, time zone, etc. etc.. Most of the DVR's a pretty straight-forward, so this is quite easy. That's it. Make sure your LCD monitor is tuned to the proper AV channel. Voila! A total sense of accomplishment, security and safety. Well worth the cash, sweat and sheer agony of running wire you invested!
