This guide is written for those who do need video protection and can’t afford precious facility services, or if the Cctv installer is not ready in your area – the later is more base than one could think. We will cover most base protection equipment types, as it is virtually impossible to go over such a wide rang of separate protection cameras and recording/video processing equipment ready on the market.
I assume whatever considering do-it-yourself Cctv facility has basic knowledge of wiring techniques and practices. I am not to be held responsible or liable for damages to the equipment due to mishandling or misuse. Remember; while the facility all the time pay attentiveness to safety. Working at heights and using tools can be dangerous, please supervene all protection practices. Lets jump right to it now.
Planning: First step of any camera facility is to plan camera and monitoring equipment locations. When planning for camera locations please take in notice light condition, never setup cameras in low light room pointing level into the sunny area it will add glare to the picture, even if your camera has back light recompense it will not be enough. Use infrared cameras for very dark conditions and/or B/W cameras with as low Lux estimate as possible. I am not going to discuss proper equipment selection, as this was branch of my last article.
Selecting the best potential camera locations is not easy, and will directly impact the camera views. Besides light conditions, the length to the monitoring object is equally important. There are many separate types and focal lengths of lenses; your choice will depend on light health and length from the camera to the monitoring object. In small rooms nearby 500sq. Ft. Cameras with accepted 3.6mm lens should be Ok. Keep in mind that most bullet and board type of cameras come with 3.6mm lens, the greater the length to the monitoring object the longer focal length of the lens will be needed. There is no ease way of judging lens selection, you can eider guess or buy professional lens selector tool.. Alternatively you can start with your lens choice and if needed get longer or shorter focal length lens later. Other choice as far as lens choice goes, is to use variable focus lens, which is very versatile approach and takes the guess out of the lens choice process. For those who do not know what variable focus lens is, it’s basically adjustable focal length lens that will allow to turn the focal length within specified range, fore example: 2.6mm – 8mm or 5mm – 50mm.
To maximize cameras coverage and get the most out of the Cctv law for least estimate of money minimize estimate of it by placing cameras in strategic places, unless perfect area coverage is needed. Avoid overlapping camera views, do not setup them with source of light directly in front of it and do not place infrared cameras pointing at each other to eliminate risk of overexposure. These are the most base mistakes that need to be avoided. After the preliminary camera locations are predetermined, lets look at cable placement. Make sure that it is undoubtedly potential and practical to run cable to each location, if running the cable to any camera location is for some guess impossible opt-out for alternate location.
Wiring: The most time curious and foremost part of any camera facility is wiring. Plan your facility determined to minimize cable lengths and insure good quality video signal. Never run cables alongside high power electrical lines, at least 12″ spacing between video cable and power lines are recommended. Keep the cable lengths below 400ft and use good quality cable, most citizen take the cable for granted, but it is undoubtedly very foremost aspect of any installation. The Cctv law is only as good as its weakest component. I normally stick with Rg59U with power Coleman cable (Yes it is Us made) sometimes called Siamese type cable. It is combo cable and will forward video and power, as an alternative it is sometimes potential to use less expensive Rg6 accepted coax cable with separate run of 18/2Awg for power.
The Siamese cable is less bulky and easer to run, distribution power supply is recommended with this type of cable as power will be supplied from base place right next to monitor and recording equipment. Using Siamese cable makes for more clean and neat installation, as only one line is required for each camera. Running Rg6 cable with separate run for power is the likely solution if power outlets are ready near each locations. In this case private plug in power supplies are used to power them with power cable running as separate and independent line to the camera. Both types of cables are ready at dvrexperts. When running the cable it is good practice to leave combine of loops of extra cable at both camera and monitoring locations. This extra length of cable is needed if in the hereafter monitoring or location will have to be moved slightly. After the cable is in place, the labor-intensive part of facility is over, now we can get to the fun part of installation.
Camera mounting: Most s come with mounting screws and bracket included, attach the bracket firmly and remember that in some cases separate brackets than the ones supplied with the cameras could be needed.
Attach the camera to the bracket and adjust the position almost at this time, we will come back to it later. Typical protection camera is powered by 12Vdc or 24Vac and power input type is screw or push terminals or 2.1mm plug. Power relationship will differ for each type of power supply and input style. Most cameras are 12Vdc, in this case it is foremost to scrutinize polarity or you may damage the camera. The power cable has two conductors and in most cases it will be red or white and black cable. Use the red or white for unavoidable and black for negative terminals. If it has screw or push terminals power input connect the cable directly observing polarity, if it is 2.1mm plug, a special 2.1Mm Female Dc Plug with Flying Leads have to be associated to the cable again keep attentiveness to polarity. The 24Vac relationship is very similar, with one major disagreement – polarity is not important.
Next step will involve some special tools and accessories. We will exertion to go over facility process of Bnc crimp-on video connector, I will post video demonstration of Bnc crimping techniques shortly so please check the web sites mentioned in this report often.
1. Take off about 1/2-inch long outer jacket from the end of video cable exposing braid.
2. Slide the crimping barrel onto the cable with the larger diameter facing end of the cable.
3. Pull the braid backwards exposing the inner isolator material and Take off 3/8-inch of it so you have now core conductor exposed.
4. The main part of Bnc connector has a small hole on one side; push the exposed core conductor of the cable into that hole as far as it will go.
5. Push all the braid folded backwards in step 3 onto the Bnc connector and spread the braid evenly nearby connector.
6. Push the crimping barrel onto the Bnc connector all the way.
7. Using crimping tool, squeeze the crimping barrel onto the Bnc connector, now the cable braid is compressed in between crimping barrel and Bnc connector assuring gain connection.
Bnc connector is on, lets hook it up now and repeat the steps for each camera, if you have purchased 16 camera law you may want to get some coffee first.
Monitor and recorder connection:
Cameras are on, its time to make final connections. I will focused on accepted Cctv monitor, standalone Dvr recorder and distribution power supply, as this is the most popular and likely solution for most Cctv installations.
First we have to setup Bnc connectors on this side as well – its time for that coffee again. It is good idea to make room for monitor and recorder now and setup some type of desk, shelf or rack to place all the equipment on.
We need the monitor and recorder in place so we can decide proper power supply location. Power supply should be mounted within combine of feet from the Dvr video inputs. After power supply is secured separate the power conductors from the Siamese cable, and run it to power supply. Like we did with the cameras if 12Vdc power is used, we need to watch the polarity, each concluding on the power supply is marked, so there should not be any doubt. Make sure the power supply is not plugged in to the power outlet yet.
Connect video cables to the Dvr video in ports. We need one video cable to connect the Dvr with the monitor, if you do not have one you may cut piece of Siamese cable separate the power conductors from it and setup Bnc connectors on both ends, you now have the cable. connect the Dvr monitor out port to monitor video in. We are almost ready to power up everything; there is only one more thing to take care before we do that.
We need to protect the equipment from power spikes by plugging it into power conditioner or good yet, buttery backup unit. If the facility location is experiencing frequent power outages, the backup unit is strongly recommended. To increase the backup time only plug the Dvr and camera power supply to the backup unit and the monitor to regular power strip, this way if we do loose power for some time the Dvr and cameras are still functioning as normal while monitor is off. Turning off monitor will not influence Dvr and cameras in any way; it is undoubtedly good habit to turn the monitor of if not used to increase its life.
Power on and final adjustment: Yes… We are now ready to power it up for the first time, if this is your first facility it may be nerve-racking experience. Start with turning the cameras power supply on, turn the monitor on as well followed by Dvr system. The stand-alone Dvr, after self-test will show cameras or setup menu on first power up depending on your model.
To setup the Dvr refer to the by hand for proper settings. Go over each camera view to decide if the view is undoubtedly what you want, hardly ever it will be without further readjustments. To properly and undoubtedly adjust the positions, the test monitor will be very handy if not principal tool. Go to each camera location and connect the test monitor to adjust the position to your preferences, if satisfied gain camera bracket adjustment screws – we will not go back to this camera anymore.
Conclusion: Congratulations! You have just completed your most likely, very first facility of Cctv system. Visit our store fore more information on lookout cameras, Dvr recorders, tools and accessories.
